Easy to operate

Ultra low temperature screw chiller manufacturerParameters:

1. The refrigeration capacity and cooling water flow rate indicated in the table refer to the parameters under the operating conditions of a cooling water inlet temperature of 30 degrees, an outlet temperature of 33 degrees, and an evaporation temperature of -40 degrees.

2. The flow rate of cooling water, the type and flow rate of refrigerant, etc. need to be determined by users according to their actual usage requirements.

When users deviate from the above standard operating conditions for a long time, it is necessary to adjust the flow of refrigerant and cooling water appropriately to ensure that the unit is in good condition.

Ultra low temperature screw chiller manufacturerWe can provide professional products suitable for users based on their different needs. For example, if a machine has multiple temperatures and requires both -20 ° C to -30 ° C and -40 ° C to -80 ° C for process use, or both -50 ° C to -80 ° C and -90 ° C to -120 ° C (but not used simultaneously), it can add the function of single-stage cooling to users or two-stage cooling to users, fully saving operating costs; If it is often necessary to cool down from room temperature to low temperature, the high-temperature stage of the cascade unit can be pre cooled to a certain set temperature before switching to the low-temperature system for operation, fully saving operating costs
