A direct cooling Chiller is a device that directly outputs refrigerant from a refrigeration system into a temperature controlled heat exchanger or control chamber component, where it evaporates and rapidly cools and maintains a constant temperature of the target equipment.

In the direct cooling type refrigeration machine, the refrigerant evaporates directly, and the cooling method is phase change refrigeration. Compared with the temperature difference cooling of liquid cooling, the cooling speed is faster, the energy efficiency is higher, the equipment has no load cooling cycle system, and the external dimensions are more compact.

The advantages of REFTEK direct cooling refrigeration machine:

1. Higher heat exchange capacity, generally more than 5 times that of secondary heat exchange;

2. Faster and more rapid cooling; Direct output of refrigerant, suitable for the demand of high heat transfer capacity and fast cooling, high temperature can quickly cool down;

3. Temperature range: -120℃~0℃;

4. High and low temperatures can be quickly switched, saving testing time and having a fast response rate;

Suitable for the new generation of energy type battery packs, it can effectively test the environmental adaptability of battery packs. Suitable for extreme performance testing of motors and battery packs, temperature rise and fall thermal shock testing, and environmental adaptability evaluation testing.

During the charging and discharging tests of batteries/cells/modules, the refrigerant directly cools the battery to reduce temperature and increase temperature.
