Low Temperature and Frozen Environment Temperature: -50℃～-25℃
When using reciprocating compressor, if the compression ratio is larger than 8-10, normally select 2-stage compressor; with R22 refrigerant, if the evaporation temperature is lower than -30℃, select 2-stage compressor.

DESIGN BENEFIT
● Equip with 2-stage semi-hermetic reciprocating compressors from Emerson Copland, BITZER, XUEYING, GEA BOCK, etc, sturdy and stable, highly efficient
● For the same evaporator and condensing temperature, its energy consumption is smaller than that of single stage reciprocating unit.
● Compared to single stage reciprocating unit, the exhaust temperature is lower and the volume capacity efficiency is higher.
● Shell and tube water condensers use high-efficient wire whorled copper pipe, which has high heat exchange efficiency. All condensers are produced and inspected strictly based on to ensure the quality.
● Air cooling condenser is punched by high velocity ram machine and fold by secondary operation. Copper pipes and fins are expanded by mechanical tube expansion to obtain high heat exchange rate.
● Adopt the refrigeration accessories from well-known brands
- Normal Configuration: filter, solenoid valve, double pressure controller, high and low pressure gauge
- Standard Configuration: shock absorber, oil separator, filter, sight glass, solenoid valve, double pressure controller, high and low pressure gauge
- Additional components are available to meet specific requirements.
