SRM Open- type Two- stage Screw Compact Compressors include 4 series totaling 12 models. Displacement 544- 5084m3/h(2960RPM), designed pressure 2.8 MPa, the designed obliquity of the compressor >30° , applicable for marine refrigeration. Applicable for the natural and environment-friendly refrigerants such as R717, R404A, R507A, etc.

Features of SRM open-type compound two-stage screw compressor:
● “I” type patented profile, best lobe ratio of 5+7, high efficiency and smooth operation.
● Rotor is made of high- quality forged steel with micron machining- accuracy, rendering excellent overall mechanical properties; high strength, high wear resistance, and long durability.
● The housing is made of high strength ductile iron.
● Nonnative shaft seal. The wear- resistant sealing surface is made of silicon carbide, rendering high reliability.
● High- precision and wear- resistant rolling bearings with the designed life of 100 thousand hours.
● Vi control function ensures high efficiency operation under various working conditions.
● Step less capacity control with the proprietary technology of explosion- proof cylinder of the capacity control.
● Integrated oil circuit: easy installation and low failure rate.

Open two-stage inverter type single screw compressor advantages:
● SRM screw compressor efficiency, COP value is higher than the same type of unit;
● Using the asynchronous machine open, high, low noise, but also matching permanent magnet synchronous motor;
● Unit using small Oil pump pre-lubrication differential pressure oil supply lubrication system, energy saving, reliable;
● The unit is equipped with an intercooler to super cool the high pressure liquid from the condenser to improve the system COP;
● Fully automatic one-button start, real-time analysis and control unit operation status, historical data storage records, can achieve remote control operations;
● Automatic energy adjustment, so that the unit can operate efficiently under different working conditions;
● Equipped with preventive safety protection system, unattended and safe and reliable;
● Components used in the unit are selected well-known manufacturers High reliability and quality assurance
● Each compressor unit undergoes full performance test before leaving the factory to ensure product quality.
