Top 5 Global Chiller Brands
Introduction
Today, the top five global brands cover almost the entire range of applications, from air conditioning in shopping centres and office buildings to complex industrial processes including pharmaceuticals, data centres and food processing. In this article, we take a look at the top 5 manufacturers whose solutions are most commonly found in projects around the world and which engineers have to deal with during the selection, installation and operation phases.
Any ranking in the engineering industry is arbitrary. In industrial refrigeration, the “best” chiller is not the one that shows the highest COP in the catalogue, but the one that most closely matches the specific application. Temperature regime, climate, acoustic requirements, service availability and budget all determine which brand is best for a given facility. In professional circles, this is known as the “fit-for-purpose” approach – selecting equipment that is maximally adapted to the purpose and operating conditions.
The focus of this review is on real experience of chillers in Europe, including aftermarket deliveries (Outlet segment), bench testing and design analyses. Our aim is not to assign “rankings” but to show the engineering logic behind each brand: where its solutions are justified and where there are alternatives.
If you need help in selecting a chiller for your facility, contact EVROPROM engineers – we will find the optimal solution taking into account your wishes and operational peculiarities.
Terms that are useful to know before continuing reading this article:
Integrated Part Load Value – Integrated Part Load Value is a standardised efficiency indicator used for refrigeration machines and heat pumps that evaluates their energy efficiency at different levels of part load.
BMS (Building Management System) – An automated building management system aimed at monitoring and controlling mechanical, electrical and plumbing processes
ESEER – European Seasonal Energy Efficiency Ratio and is the European standard for measuring the seasonal energy efficiency of air conditioners and chillers
Microchannel condenser (MCHX) is an efficient condenser that uses microchannels of up to 1mm to optimise heat transfer. It uses a series of parallel microchannels to convert the condenser pipework into thousands of microchannels, thereby providing a larger heat transfer area.
kWh/tonne– the unit of measure is kW electric per tonne of cold. “Tonne of cold” is an Anglo-Saxon unit of cooling capacity still used in the USA and in international chiller catalogues.
Evaluation approach and disclaimer
This review is not intended to be an “objective ranking”. In the chiller industry, it is pointless to compare brands directly: each manufacturer has its own specialisation and target niche. That is why we use the “fit-for-purpose” principle, evaluating equipment based on a combination of operational factors rather than catalogue indicators.
The main criteria for analysis:
- Reliability – build quality, durability of heat exchangers, compressor life.
- Repairability and service – availability of original components, cost and availability of service, software “openness” of automatics.
- Liquidity in the secondary market – demand, condition of units after 8-10 years of operation, adaptation to climate and environment.
- Engineering culture of the brand – design logic, unification of units, depth of customisation for non-standard tasks.
We rely not only on official technical data, but also on the experience of equipment operation, which has been delivered and tested at European facilities. This makes it possible to separate real advantages from marketing claims.
Take a look at our catalogue of chillers – units in various configurations, carefully checked for defects, adjusted to the required temperature regimes and shipped to you in perfect condition.
1. Trane (USA)
Trane is traditionally considered one of the most reliable manufacturers of refrigeration equipment in the world. This brand is a kind of “benchmark” of engineering quality in the segment of industrial chillers. The company is active in the European market: assembly sites are located in France and the Czech Republic, and the products cover a range of capacities from 50 kW to 10 MW.
Screw and centrifugal chillers form the basis of the range.
- The RTHD, RTWD (water-cooled) and RTAF (air-cooled, Sintesis™ range) screw units cover the 250-1800 kW range. Trane utilises proprietary screw compressors with hydraulically controlled capacity, ensuring stable operation under variable loads and high EER.
- The CenTraVac™ (CVHE / CVHF) and Series R™ centrifugal chillers are industrial machines with capacities up to 10 MW. They are characterised by minimal vibration, high durability and the ability to use low GWP refrigerants (R1233zd(E), R514A).
- In recent years, Trane has been actively introducing oil-free magnetic bearing compressors (Turbocor range), offering solutions for facilities with variable loads such as data centres, ice arenas and pharmaceutical plants.
Trane is deservedly considered a favourite of service engineers in Germany and Northern Europe. Units of this brand retain a high resource of heat exchangers and condenser sections even after 10 years of operation. On the secondary market you can often find chillers with fully working sections that require only preventive cleaning.
Among the disadvantages, experts note the high cost of service maintenance and licensed policy in terms of controller firmware (it is impossible to simply “disconnect the sensor” without access through the official service), the difficulty of supplying original spare parts when repairing large centrifugal machines.
At the same time, performance remains among the best in the industry. Trane screw compressors provide up to 80-100 thousand hours of service life, and centrifugal units often operate for more than 20 years.
Many engineers believe that Trane has never made a reciprocating chiller, but that’s not entirely true. In fact, it did, especially until the late 1990s. It is just that these models were gradually replaced by branded screw and centrifugal solutions, and today this period is hardly remembered:
Obsolete Traneseries
| Series | Refrigeration type | Compressor | Power range, kW | Notes |
| CGF / CGW / CGL | Air / water | Piston (Trane / Copeland / Carlyle) | 40-250 | Most mass-produced models of the 80s-90s; used R22 |
| CCF / CCU | Air | Piston (Copeland) | 50-200 | Compact chillers for small to medium sized buildings |
| RTAA (early versions) | Air / screw | Mixed configuration – piston in early versions | 150-400 | Later replaced entirely by screw design |
| RCA / RCF Series | Water cooled | Piston (Bitzer / Trane) | 80-300 | Industrial and commercial R22-era models |
| CGAM (early) | Air | Piston → Scroll | 70-200 | Transition versions used piston versions before upgrading to R410A |
These models were common in Europe and the USA in the 1980s and 1990s. Carlyle or Bristol / Copeland semi-hermetic reciprocating compressors were used, depending on the model. These units were designed as “small commercial” and domestic refrigeration machines – mainly for the US market. The switch to R407C and R410A in the 2000s made the reciprocating ones obsolete – Trane replaced them with Copeland scroll compressors and Helical Rotary’s own screw compressors.

Modern Trane series
| Compressor type | Series | Compressor manufacturer | Capacity range, kW |
| Scroll | Thermafit AXM, CGAM, CXAM | Copeland / Trane | 50 – 400 |
| Screw (Screw / Helical Rotary) | RTAF, RTWD, RTHD, XStream RTHF | Trane (in-house production) | 250 – 2 500 |
| Centrifugal (Centrifugal) | CenTraVac (Series E, CDHF, CDHF-SE) | Trane (in-house) | 700 – 10 000 |
| Turbocore (Magnetic Bearing Centrifugal) | XStream RTHF E, High-Efficiency Chillers | Danfoss Turbocor | 400 – 1 500 |
2. Carrier (USA)
Carrier is one of the oldest and most recognisable brands in the HVAC world. Founded by Willis Carrier, the inventor of mechanical air cooling, the brand has come to symbolise the widespread adoption of chiller technology. Today, Carrier is part of Carrier Global Corporation, with European manufacturing facilities in France, Italy and the Czech Republic.
For the European market, Carrier remains one of the main suppliers of medium and large capacity air and water cooled chillers. Its products are well known not only in new projects, but also in the aftermarket for their high liquidity and ease of operation.
The Carrier range covers almost the entire range of chiller capacities – from 100 kW to 5 MW.
The main model lines are:
- 30RB / 30RQ – AquaSnap™.
Air chillers and heat pumps on Danfoss Scroll compressors. Capacity 150-1100 kW, high EER (3,0-3,4), integrated hydronic module and noise-absorbing housings. It is one of the most massive and popular ranges in Europe, especially in office and retail buildings. - 30XW / 30GX – AquaForce™.
Water-cooled units with Carlyle screw compressors (Carrier’s own manufacture). Range 300-1800 kW. Series is targeted at industrial applications and large commercial buildings. - 19XR / 19XRV – centrifugal chillers.
Large units with a power range of 700-6000 kW. Used in industrial facilities, data centres and hospitals.
Fig.1 – CARRIER 30RBSY 87 kW chiller in our catalogue
Carrier is actively developing microchannel-capacitor technology (MCHX) to reduce weight and refrigerant consumption. The Touch Pilot™ automation system supports BACnet and Modbus, with an intuitive interface and remote monitoring.
Carrier is one of the most common brands in the aftermarket. This is due to the wide geography of sales and the fact that the units are relatively unpretentious in maintenance. However, engineers note several peculiarities:
- Microchannel sections after 8-10 years of operation often require replacement or local repair – aluminium is susceptible to corrosion in an aggressive environment.
- The cost of original spare parts and service work is higher than the market average.
- Carlyle compressors can rarely be overhauled – in most cases the unit is replaced.
On the other hand, Carrier units are easy to install, work steadily at unstable voltage and do not impose strict requirements to the quality of water in the circuits. For facilities with moderate loads and limited budgets, this is often a decisive argument.
Carrier’s modern series
| Compressor type | Compressor manufacturer | Compressor manufacturer | Capacity range, kW |
| Scroll | 30RB, 30RAP, 30MP, 30WG | Danfoss / Copeland | 30 – 900 |
| Screw | 30XW, 30XBV, 30XF, 23XRV | Carlyle (Carrier own brand) | 400 – 2 500 |
| Centrifugal (Centrifugal) | 19XR, 19XRV, 19DV | Carrier (own brand) | 700 – 10 000 |
| Turbocore (Magnetic Bearing Centrifugal) | AquaEdge 19DV, 23XRV | Danfoss Turbocor | 400 – 2 000 |
| Piston (Reciprocating) | Old 30GA / 30GT series (withdrawn) | Copeland / Carlyle | – |
Carrier used to produce reciprocating chillers – these can still be found on the aftermarket. Today, the series on reciprocating compressors have been discontinued. All modern models are either scroll, screw or centrifugal. Carrier was one of the first to switch to Danfoss Scroll compressors (back in 1999-2001) and then extended them to the entire AquaSnap series.
3. York / Johnson Controls (USA / EU)
The York brand, now part of Johnson Controls International, remains one of the oldest and most respected chiller manufacturers in the world. Its history dates back to the 19th century, and today’s range ranges from scroll and screw units to large centrifugal chillers with a capacity of over 10MW.
York focuses on centrifugal and screw chillers, offering solutions for both commercial and heavy industrial applications.
- YK / YZ centrifugal chillers.
The YK series are classic centrifugal units with capacities from 700 kW to 10 MW. The IGV (Inlet Guide Vanes) control system is used in combination with VFD (Variable Frequency Drive) for smooth performance control and high IPLV performance.
The YZ series has become the brand’s flagship, the first fully oil-free centrifugal chillers with single-stage magnetic bearing compressors. Their efficiency in partial modes reaches 0.31-0.33 kW/t, making them among the most energy-efficient machines in the world. - YS / YVFA / YCAL screw chillers.
The YS (water-cooled) series – 200-2000 kW range, with York’s proprietary screw compressors. YVFA range – modern air handling units with micro-channel sections and free-cooling system, designed for operation in northern climates.
YCAL is a popular range of 150-1200 kW air chillers, often found in Europe in office and retail type facilities.
Among the disadvantages, engineers note several practical nuances:
- York units have many parts that are customised – fans, sections, mountings and housings differ in size from standard solutions, making replacement more difficult.
- Centrifugal compressors are highly skilled in maintenance and balancing.
- The cost of service work is comparable to Trane, but spare parts are sometimes harder to find in stock in Eastern Europe.
At the same time, York has obvious advantages: the units are stable under variable loads, they quickly get up to speed, and compressor service life reaches 70-90 thousand hours.
Fig. 3 – York 787 kW chiller in our catalogue
Until the early 2000s, York produced a range of piston chillers and heat pumps with small and medium capacities. These were units for office buildings, hotels and server rooms – simple, reliable but energy-intensive by today’s standards.
Obsolete York series
| Series | Cooling type | Compressor | Power range | Notes |
| YCAL (early versions) | Air | Piston (Copeland / Carlyle) | 50-250 kW | Later replaced by scroll |
| YCWL / YCAL R22-era | Water / air | Piston hermetic | 40-200 kW | Worked on R22 and R407C |
| YCAM / YCCL | Air, modular | Piston (Bitzer / Copeland) | 60-180 kW | Older series late 90’s |
| YCAS (transitional series) | Air | Screw (first generation) | 250-1000 kW | Becoming a replacement for piston units |
After 2004-2005, all models with reciprocating compressors were discontinued because they did not support inverter control, had low seasonal efficiency (ESEER ~2.5-2.8), and did not meet new requirements for noise and refrigerants (R22 → R410A / R134a). All modern York chillers are screw or centrifugal (including oil-free YZ).
Modern structure of the York series
| Compressor type | Compressor manufacturer | Compressor manufacturer | Power range, kW |
| Scroll | YCAL, YCWL, YVAG | Copeland / Danfoss | 80 – 800 |
| Screw | YS, YVFA, YVWA | York (own) | 200 – 2 000 |
| Centrifugal (Centrifugal) | YK, YD | York (own) | 700 – 10 000 |
| Oil-free centrifugal (Magnetic Bearing Centrifugal) | YZ | York (own design with magnetic bearings) | 400 – 3 000 |
York is completely self-sufficient in the manufacture of screw and centrifugal compressors. It was York that first brought to market the completely oil-free YZ centrifugal chiller, which has become the benchmark for energy efficiency. Third-party scrolls are used in the small segment, but all medium and large capacity is Johnson Controls’ own engineering.
4. Climaveneta (Italy, Mitsubishi Electric Group)
Climaveneta is a leading Italian manufacturer of chillers and heat pumps, known for its combination of energy efficiency, low noise and sophisticated automation.
The company was founded in 1971 in Bassano del Grappa (northern Italy) and became part of the Mitsubishi Electric Hydronics & IT Cooling Systems (MEHITS) group in 2015. Despite the integration into the Japanese corporation, Climaveneta has retained its own engineering school and remains focused on the European market.
Climaveneta traditionally relies on energy-efficient screw and inverter chillers, as well as on hybrid systems – capable of simultaneous cooling and heating.
- Air chillers of the i-BX, i-FX, FOCS series.
Power range – from 50 to 1200 kW. Screw and scroll compressors (Copeland, Bitzer), EC fans and microchannel condensers are used. The i-FX and FOCS-V versions utilise inverter control and multi-compressor circuits, resulting in high seasonal ESEER > 4.5. - TECS2 and i-AX water-cooled chillers.
Capacities are 400-2500 kW. Equipped withflooded evaporator or oil-free Turbocor screw compressors for high energy efficiency and compactness. The TECS2-W/HC versions operate in heat pump mode. - Polyvalent systems and 4-pipe solutions.
The NECS-Q and i-FOCS ranges are capable of producing cold and heat simultaneously, balancing the load between consumers.
Fig. 4 – Chiller/Heat Pump Climaveneta I BX N 025T HANRV 24.7 kW/26.1 kW in our catalogue
Climaveneta is well established in the European market as a reliable and “technological” brand. Engineers note that even chillers of 10-15 years of age remain functional with minimal intervention – especially models of FOCS and TECS2 series. The build quality is consistently high: good frames, neat wiring, well thought-out drains.
However, there are some peculiarities:
- Bitzer and Piller screw compressors in older series are difficult to repair – in case of serious failures, the whole unit is replaced.
- The cost of original spare parts and in-house service is higher than the market average.
- In the newer series, there is a focus on automation: intervention without access to software is limited.
On the secondary market, Climaveneta chillers are in demand due to the durability of heat exchangers and resistance to corrosion. Microchannel sections, unlike some competitors, often remain in good condition even after 8-10 years of operation.
Initially, the company did not manufacture its own compressors but purchased them from Bitzer, Maneurop, Copeland and Bock. The evolution of Climaveneta’s compressor technology therefore reflects the general shift in the European HVAC market from reciprocating to screw and scroll solutions. From the 1970s to the early 2000s, Climaveneta made extensive use of reciprocating compressors – primarily Bitzer and Maneurop (Danfoss).
Obsolete Climaveneta series
| Series | Refrigeration type | Compressor | Power range, kW | Notes |
| NECS / NECS-C (early versions) | Air | Piston (Bitzer / Maneurop) | 40-250 | Used R22 / R407C, the most mass-produced models of the 90s |
| FX / FXC | Air / water | Piston (Bitzer / Copeland) | 80-300 | Transitional series before the introduction of screw compressors |
| RS / RSE | Water cooled | Piston (Bock / Bitzer) | 100-350 | Used in industrial applications |
| RECS / RECS-Q | Air cooled, heat pump | Piston (Maneurop / Bitzer) | 50-200 | Models with heating option; discontinued in 2004-2005. |
After 2005, with the introduction of the FOCS, TECS, i-FX series, Climaveneta switched completely to screw and scroll compressors, and later to inverter and Turbocor compressors. The switch to scroll and screw compressors has improved energy efficiency (EER / ESEER) by 20-30 % in partial operation modes. Reducing noise and vibration has become particularly important for residential and hospitality applications, a key segment for the company. Also reciprocating compressors are not well compatible with modern refrigerants R410A, R134a and R1234ze, which required switching to new technologies. Simplification of service was another advantage – scroll compressors do not require major repairs (they are simply replaced), while screw compressors are serviced much less frequently. Finally, the new MEHITS range integrates with Mitsubishi “smart” automation, where the use of frequency control is critical, which is conveniently realised exactly on scroll and screw units.
Modern Climaveneta series
| Compressor type | Application (series) | Compressor manufacturer | Power range, kW |
| Scroll | i-BX, NECS, NECS-Q, i-FOCS | Copeland / Panasonic | 50 – 500 |
| Screw | FOCS, TECS2, i-FX, i-AX | Bitzer / Piller | 200 – 2 500 |
| Turbocor (Magnetic Bearing Centrifugal) | TECS2-HFO, i-AX Turbocor | Danfoss Turbocor | 400 – 1 200 |
| Inverter Scroll (Inverter Scroll) | i-BX / i-FX (new versions) | Mitsubishi Electric / Copeland | 80- 800 |
Climaveneta uses external compressors (Bitzer, Copeland, Turbocor), concentrating on system integration and energy efficient automation. The brand does not manufacture compressors itself, but masterfully applies different types to the task – including hybrid schemes and 4-pipe systems.
5. Daikin (Japan / Italy)
Daikin Industries Ltd. – is the largest Japanese corporation in the field of air conditioning technology, one of the few manufacturers that independently designs both compressors, automatics and refrigerants. In Europe, Daikin chillers are manufactured at plants in Italy and Belgium, including Daikin Applied Europe (formerly McQuay).
Daikin combines Japanese precision and Italian engineering school. The range is based on air and water-cooled chillers with screw, scroll and centrifugal compressors.
- EWAD / EWWH – screw chillers.
The EWAD (air-cooled) and EWWH (water-cooled) series cover a power range of 200-2000 kW. The units utilise in-house developed screw compressors with Variable Volume Ratio (VVR) technology to maintain high EER at partial load. In the basic configuration – flooded evaporators (flooded), new versions use R1234ze refrigerant with low GWP. - EWAT / EWWT – medium capacity chillers.
They use Danfoss or Copeland scroll compressors and inverter control of fans. The capacities are 100-800 kW, EER at the level of 3.1-3.5. These are the most popular machines in the commercial sector – offices, shopping centres, hotels. - TurboChi™ – centrifugal chillers.
Units on oil-free compressors Turbocor (magnetic bearings), capacity 400-2000 kW. They are characterised by high IPLV < 0.33 kW/t, low noise level and minimal oil consumption (in fact, its absence).
Fig. 4 – DAIKIN 459 KWT chiller in our catalogue
Daikin is actively introducing inverter technology and heat recovery. In 4-pipe configurations, the chillers are able to cool and heat different areas of the building simultaneously.
Engineers note that the units maintain parameters even under unstable environmental conditions, and controllers provide precise regulation of performance.
In the EWAD and EWWH models, the reliability of heat exchangers and the tightness of freon circuits remain at a high level even after 10 years of operation.
However, there are also limitations:
- Electronic components are sensitive to voltage fluctuations and grounding quality – especially in older series.
- Italian-built units (Daikin Applied Europe) have reported cases of leakage on microchannel sections in aggressive environments and high humidity.
- The cost of original electronics and control boards is relatively high, and third-party analogues are not always available.
Despite this, on the secondary market Daikin is valued above most analogues due to energy efficiency and predictable behaviour of the equipment in variable modes.
Daikin used to use reciprocating compressors, but today has completely abandoned them in both chillers and heat pumps. It was one of the first manufacturers to consciously move away from piston compressors back in the 1990s, relying on its own screw and scroll compressors, and later on oil-free Turbocor centrifugal compressors.
In the 1970s and 1990s Daikin produced small and medium-sized chillers with reciprocating compressors for offices, hotels and industrial facilities.
Obsolete Daikin series
| Series | Chiller type | Compressor | Power range, kW | Notes |
| EWJ / EWJP | Air | Piston (Daikin / Bock) | 40-200 | Used on R22, R407C |
| RWE / RWF Series | Water | Piston (Daikin) | 60-250 | Old industrial units, discontinued by 2000. |
| UAY / UAYY / UAYP | Air / heat pump | Piston (Bock / Matsushita) | 50-150 | APAC (air-to-water) versions popular in Asia |
| WCC / WCF (Water Cooled Chillers) | Water Cooled Chillers | Piston | 80-300 | Operated on R22, used in hotels and office buildings |
After the early 2000s piston compressors were completely replaced by scroll and screw and later by Turbocor centrifugal compressors.
Modern Daikin series
| Compressor type | Application (series) | Manufacturer | Power range, kW |
| Scroll | EWAT, EWWT, EWYD-Q | Daikin / Copeland | 80 – 900 |
| Inverter Spiral (Inverter Scroll) | EWAT-B / Mini Chillers / VRV | Daikin (own, Japan) | 30 – 200 |
| Screw | EWAD, EWWH, EWYD | Daikin (own) | 300 – 2 500 |
| Centrifugal (Centrifugal) | TurboChi, EWCH | Daikin / Turbocor | 400 – 2 000 |
| Oil-free centrifugal (Magnetic Bearing) | TurboChi R1234ze, EWCH-VZ | Danfoss Turbocor | 400 – 1 500 |
Daikin is one of the few brands producing its own screw and scroll compressors. The company integrates them with proprietary automatics and refrigerants (R1234ze, R32). In premium ranges are used magnetic bearing Turbocor, and for VRV-systems – completely own inverter scroll-compressors. Daikin’s core philosophy is vertical integration and precise energy management.
Conclusion
The analysis of the five leading global chiller brands confirms that there are no universal solutions: each manufacturer occupies its own niche, emphasising certain technical features.
- Trane is the benchmark for reliability and service life. Suitable for facilities with continuous operation and high criticality (industry, ice arenas, data centres), where higher initial capital and service costs are acceptable.
- Carrier is the universal choice for the mass commercial market, favourable for limited budgets and wide service network coverage.
- York / Johnson Controls – premium positioning with emphasis on low noise and high efficiency centrifugal solutions, good for projects with acoustic and energy efficiency requirements.
