Two stage screw rack is specially designed for IQF / Dual spiral / blast freezing and any low temperature application. The efficiency of two stage screw is much higher than single stage screw, especially when the evaporating temp. is lower than -40C, the energy saving percentage against single stage screw will get bigger when the evaporating temperature is getting lower. Cryotek uses Kobelco two stage screw compressor with Inverter control as option, each single Kobelco inverter compressor can reach 25-100% operation range

Cryotek is able to supply Freon screw equipment which can meet 3-4 ton IQF or dual spiral application. R22 / R404A, evaporative condensing / water cooled are available.
