Brief
The series units come from the 170 series ammonia compressor units. The units adopt Y series high-efficient energy-saving electric motor with the protection class of IP23. Therefore, besides running at high velocity, small volume, parts is easy to interchange, starting with empty load and charging oil while running like the 170 series units, the units feature higher efficient, more energy-saving, smaller area to place and higher liabilities.
This series compressors is suitable for all kinds of refrigeration conditions within condesing£¼46¡æ, single stage evaporating temp +5¡æ~-30¡æ, two stage evaporating temp -25¡æ~-45¡æ.
Ammonia and Freon can be both adopted as refrigerant of compros, different revolutions can be designed in accordance with clients exact requirements. All the data in this caalog is based on ammonia compressor..
