(1) Adopting the new generation SDC high efficiency screw profile, the free-form surface is sealed to reduce the length of the contact line while minimizing the leakage triangle area.
(2) Adopting two-stage comoression technology, without pre-cooling, the evaporature temperature can be directly reduced from cold storage temperature to -65ºC.
(3) The motor is arranged between the low-pressure and the high-pressure stage, to prevent condensation or frost in the motor shell and the terminal box to ensure electrical safety. At the same time, the internal flow path is optimized to reduce pressure loss.
(4) Both the suction side and the replenishing side are large-area filters, which protect the compressor while reducing the pressure loss.
