Performance Characteristics And Application Of Water Cooled Low Temperature Brine Chillers?

Jul 28, 2017

This unit is an industrial chiller that can provide low temperature brine below 0 ° C for cooling the process sectors such as grain processing, food processing, chemical, pharmaceutical and other industrial sectors.

The structure of the low temperature brine chiller is similar to that of the standard piston chiller, and the refrigeration cycle also has a single stage compression cycle and a two stage compression cycle. In addition, in order to ensure the normal operation of the chiller, also set the energy adjustment device, overpressure, oil pressure is too low, water, motor overload and other automatic protection device.

Low temperature brine chillers used in the refrigerant (low temperature brine) is mainly aqueous ethylene glycol solution, sodium chloride aqueous solution and calcium chloride aqueous solution, especially the most commonly used ethylene glycol solution. Their use temperature range is as follows: ethylene glycol aqueous solution 4 ~ -20 ℃, sodium chloride solution -15 ~ 25 ℃, calcium chloride aqueous solution -20 ~ -45 ℃.

According to the different industries, low temperature brine water temperature is not the same, should be based on the user's actual needs, but it should be noted that the freezing point of salt water and salt concentration, so the preparation of brine concentration must ensure that the chiller in the evaporator Does not freeze. The actual use of temperature, should be higher than the freezing point of salt 5 ~ 8 ℃.
