чиллеры hitachi

Chiller – is a refrigeration unit for air conditioning in commercial premises. Industrial chillers have a wide range of applications. They are used in the wine industry, production of plastics, mechanical engineering and metal processing, food, chemical and pharmaceutical industries for a variety of technical needs, as well as for ice rinks and swimming pools. The chillers maintain the required temperature for the productive operation of the equipment.

Chiller is the industrial equipment for cooling of a liquid which in turn cools through heat exchanging equipment objects of conditioning or production processes. Thus, the unit performs one of the most important functions – cooling without which the existence of most office, residential, commercial premises and production processes is impossible.

How does the chiller works?

Cold production process occurs in a closed circuit, where involved three main nodes:

• 1. cooling Compressor
• 2. evaporator (heat exchanger)
• 3. condenser

The compressor compresses freon gas where it is heated to 80-90 degrees and enters the condenser. Installed above the heat exchanger fans cool the freon flow of incoming air to a temperature slightly above outdoor air. Next the refrigerant enters the filter dryer and after passes through the thermostatic expansion valve (TEV).

The next step is the most important, is the transition in freon exchanger where he boils and going from liquid to gaseous takes heat from coolant, resulting in water or glycol cooled to the temperature and the freon is heated to the State of the couple, and then returns to the compressor and the process is repeated.

To date, industrial chiller selection is huge, and is chosen based on the task at hand.

Types of Chillers

• 1. By condenser cooling type: air and water cooled 2. By type of execution: split system or bar
• 2. By noise level: standard, low noise and super low noise.
• 3. By temperature mode: high temperature, average temperatures, and low-temperature.
• 4. By type of compressors: screw, scroll or reciprocating type.
• 5. By type of heat exchanger: plate or shell-and-tube.
• 6. By hydro-module type: full hydro-module, with a pump and expansion tank, pump and cumulative capacity, with two pumps, without hydro-module.
• 7. With additional features: recovery of heat, heat pump, free cooling.

Manufacturers and Brands

(Information Written Exclusively from our Experience)

Industrial chillers produce worldwide ranging from manual garage Assembly and ending with international concerns with the robotic assembly sites.

But nevertheless, we would like to share them this way:

Chillers of American Brands

Standard of Quality

TRANE is the most reliable and durable chillers. Made with high quality materials and modern technologies. Install the spiral and screw compressor, various types of heat exchangers, which makes it possible to use them for all kinds of tasks from low temperatures on the ice arenas before chilling mold.

Carrier is a sweetie, and most famous brand. Just one title that it wanted to acquire, stylish design and modern technology often use heat recovery and heat pumps, as well as their production Rotary screw compressors. Pro control system-dialog with the touchpad makes management easier and faster. Carrier is most often used for air conditioning of buildings.

York – excellent machines, the leaders of the field of manufacture of refrigerating machines. Manufacturing them for the European market in the UK. Are based on the screw and scroll compressors. Suitable for use in low temperatures.

Lennox is a little less common chiller from the American brand. In Europe appeared after the merger with the Dutch brand REFAG. However, the excellent quality, often produces small models with scroll compressors installed. Often protected from aggressive sea air condenser.

Chillers Produced in Germany and France

Riedel – the company specializes in production of machines for cooling molds in the manufacture of plastic products as well as cooling laser metal cutting. Equipped with scroll compressors, and hydro module with a pump.

OPK – rarely used technique, however, like all German is not deprived of attention to detail. Chiller is made on the basis of scroll compressors, equipped with additional sound-insulated heating by irradiation in cold period of time, and other things that help in its operation.

Ciat – chiller from the French manufacturer. Durable and easy to operate, up to the year 2000 were painted in blue and assembled piston compressors. And now this machine based on the scroll Copeland compressors that use energy-saving technologies.

Chillers Produced in Italy

Climaveneta – who does not know this brand in Ukraine. Sample of the perfect Italian chiller. Often the covering is made of stainless steel, it looks very impressive. In addition, Italians are keen to be the first in the field of energy saving by releasing a new generation of models IFX with inverter compressors Bitzer.

Geoclima – little known company in Ukraine, but it should be noted that the quality of these cooling units is always on top. Use of quality metal and first-class European components in the manufacture of the chiller, makes these machines stable robot and has no impact of weather conditions.

There are many good brands such as: MTA, Stulz, Airwell, McQuay, Hiross, Clivet…

Some of them have already been produced under a different name as included in other companies but produced models still serve their true owners.

Used chillers from Europe from the company Europrom working for a long time in the most various spheres of services and industry:

• Dairies
• Breweries and private brewery
• Ice arenas and skating rinks
• Manufacture of cosmetics and chemistry
• Thermoplastic automatic machines and extrusion lines Cooling vegetables: carrots and corn farm
• Mushroom farms
• Shopping centers and hotels
• Sunflower oil Cooling
• Wineries
