Water-cooled Chillers丨Ultra-low Temperature Chillers丨Cryogenic Chillers
1. A liquid low temperature cooling using heat transfer medium, used in chemical, pharmaceutical, military, aerospace, biochemical industries, low temperature, ultra-low temperature process, supporting extraction, distillation, reaction kettle… for filtration, crystallization… reactions.
2. It can cooperate with CBD equipment, CO2 extraction equipment, PVD equipment, etc. to provide low circulating temperature for the reaction process.
The water-cooled chiller uses a shell-and-tube evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat in the water. After the water is cooled, the heat is transferred to the shell-and-tube condenser through the compressor. After the water absorbs heat, the heat is taken out to the external cooling tower through the water pipe for heat dissipation.
Ultra-low Temperature Chillers
Temperature Range -60°C ~ -10°C
Cooling Capacity Up to 360kW
Circulating Pump 6.6m³/h~25m³/h 2.5bar
Temperature Range -110°C ~ -50°C
Cooling Capacity Up to 120kW
Circulating Pump 6.6m³/h~25m³/h 2.5bar
Single-fluid ultra-low temperature chiller, the cooling temperature range is from -150 degrees to -5 degrees, which can meet different cooling temperature needs.
The whole system is a fully closed system, and there is no water absorption during low temperature operation, which ensures the purity of the cold heat transfer medium, prevents ice crystals, and improves the life of the heat transfer fluid.
The direct-cooling ultra-low temperature freezer developed by LNEYA adopts international brand compressors and single-compressor automatic cascade refrigeration technology. It can be cooled to minus 120°C within 3 minutes, and the cooling speed is fast, safe and reliable.
Ultra-low Temperature Chiller Can Be Either Air-Cooled Chiller Or Water-Cooled Chiller. The Choice Of Air Cooling Or Water Cooling Depends On Your On-Site Process Conditions And Requirements, You Can Explain To Us At The First Time, So As To Better Choose Model.

Basic Structure Of Chillers
Industrial water chiller consists of compressor, condenser, evaporator, expansion valve and other accessories.
- Compressor: in the industrial water chiller system, the compressor is the power to ensure refrigeration. The compressor is used to increase the pressure of the refrigerant in the system and make the refrigerant circulate in the refrigeration system to achieve the purpose of refrigeration.
2.Condenser: high temperature and high pressure Freon of the refrigeration system enters the condenser after coming out of the compressor, releases a lot of heat to the cooling medium, and then is cooled and liquefied.
3.Evaporator: when the Freon liquid of the refrigeration system enters the expansion valve for throttling and is sent to the evaporator, it belongs to the vaporization process. At this time, it needs to absorb a lot of heat to gradually reduce the valence and mass temperature to achieve the effect of refrigeration and cooling.
4.Expansion valve: in the refrigerant system flow chart of the industrial water chiller, we found that there is a small part between the outlet of the condenser and the inlet of the evaporator, which is called thermal expansion valve. It is a throttling and depressurizing part to reduce the condensation pressure of the refrigerant to the evaporation pressure. Therefore, its role in the refrigeration system is essential. It is connected with the refrigeration compressor, evaporator, condenser It is also called the four components of the refrigeration system.
5.Other accessories: including drying filter and high and low pressure controller. The drying filter is non detachable. The internal structure adopts molecular sieve structure, which can remove a small amount of impurities and water in the pipeline, so as to purify the system. The high and low pressure controller plays a protective role in the refrigeration system.
