Why is it important to test a chiller before purchase?

A chiller is the heart of a cooling system. It maintains the required temperature for production processes, directly impacting quality, shelf life, and manufacturing precision. The more critical the process, the higher the expectations for equipment stability.

When choosing a chiller, especially a used one, you want to be sure it can handle the task. Errors in selection or insufficient testing can result in:

• Increased energy consumption
• Unstable temperatures
• Production line shutdowns
• Frequent failures and financial loss

That’s why at Evroprom, we test every chiller — from 20 kW to 1100 kW — on our in-house test station. This is not just a basic start-up check. It’s a full simulation of real operating conditions.

Where are chillers used — and why Is testing critical?

Liquid cooling systems are essential in dozens of industries where accurate and stable temperatures are critical:

• Food industry: cooling of milk, cheese, beer, wine, beverages, chocolate
• Pharmaceuticals & cosmetics: strict standards, regulations, stability
• Chemical industry: temperature-sensitive reactions
• Engineering, casting, injection molding: product quality control
• Greenhouses & mushroom farms: microclimate regulation
• Ice arenas, hotels, logistics centers: comfort & reliability

A properly tested and configured chiller:

• Increases productivity
• Reduces operating costs
• Extends equipment lifespan

What is the Evroprom test station?

Our chiller test station is a universal system that allows us to test any chiller — any size or type, including refurbished units.

Station features:

• 5000-liter water tank
• Pump system with various diameter connections
• Simultaneous testing of multiple chillers
• Suitable for year-round testing — from summer to winter modes
• Continuous monitoring of all operating parameters

What do we measure?

During testing, we run a complete cooling cycle from +20 °C to +5 °C. All components operate under realistic conditions while our specialists monitor dozens of parameters.

We test:

• Refrigerant pressure (via manometers) — crucial for evaluating compressor function and refrigerant level
• Temperature delta at heat exchanger inlet/outlet

We also check:

• Compressors: startup, current, stability
• Inverters: not only fans, but also compressors/pumps
• EEV/TEV: correct opening, superheat stability
• Controller: configured for the customer’s project
• Hydronic module: tightness, pressure, performance
• Flow switch: response to flow presence and sufficiency
• Electrical equipment: fan/pump/compressor windings resistance
• Temperature and pressure sensors: accuracy

Main test stages:

• Connecting chiller to the hydronic module
• Running cooling cycle, analyzing compressor behavior
• Testing EEVs and sensors
• Verifying main chiller components: compressors, fans, pumps
• Controller configuration
• Testing hydronic system performance
• Final stability test

Optional services:

• Heat exchanger cleaning
• Fin straightening
• Condenser washing
• Oil & filter replacement
• Final washing & packaging
