Ammonia screw parallel compressor unit with integrated recirculation system

This type of product is developed based on the single-stage open-type screw compressors of Bitzer and MYCOM etc. It uses two

or more compressors in parallel, with a wider range of gas displacement, operating conditions covering low temperature,

medium-temperature and high temperature. (-50 ℃～+20℃). Operating energy regulation is more flexible. Mainly suitable for

R717 (NH3), R507A or R404A. It can achieve automatic energy regulation and automatic Vi adjustment. According to operating

conditions, economizer components can be selected to effectively increase the COP. Fixed frequency or variable frequency

motor can be configured for frequency conversion operation. Safer and more reliable top brands electric components such as

Siemens, ABB, Schneider, etc. The unit adopts a three-dimensional optimization design and a fully automatic control system,

which can completely achieve unmanned operation.
