Special valve design, high stability, long service life

large refrigerating capacity

Perfect low temperature performance; for R22 refrigerant, single compressor evaporating temperature can reach -40℃.

Used in a variety of refrigerant such as R12, R22, R502, R134a, R404A, and R507 . Comply with environmental requirements

Using the sub-coils start can reduce the impact on the grid. The design of special technical parameters and the new development of the rotor components can increase the efficiency.

A wide range of applications: high temperature and low temperature type. The evaporation temperature of high temperature type can reach 12.5 ℃; the low temperature type evaporating temperature of single compressor can reach up to ( R22 ) -40 ℃. The evaporating temperature of two-stage compressor can reach -50℃( R22 ). Lower evaporating temperature can reach up to -70℃,if using R404a or R507

The built-in motor overloading protection device ( INT69VS ) can protect the motor from overloading and overheating as the load of refrigeration system is increasing or the gas shortage of refrigerant happens.

In order to prevent excessive starting current, customers can also choose unloading device.

In order to reduce the exhaust gas temperature, customers can choose water cooled cylinder.
