This series unit is widely applied in ship, has a greater demand cooling capacity, for food preservation, refrigerated, frozen, low temperature processing, marine air conditioning etc. Such as tuna fishing boat, a large squid fishing boats, large ocean seine, trawl processing vessels etc.

High-efficiency

*The 4th generation high-performance rotor profile with international advanced level. Being processed by advanced HOLYROYD exclusive rotor grinding machine to ensure the most accurate precision and high efficiency.

*The outside diameter of the male rotor and female rotor is equal, the circumferential velocity tends to the optimal value, the compressor efficiency improved significantly.

*Oil pump supplies oil continuously and make compression process close to no temp change. Lubrication oil forms a film on the seal line to reduce inner leakage and increase volume ratio.

*High-efficient oil separator and oil cooler ensure low oil consumption and high heat transfer efficiency.


High Reliability, Long Running Life, Good Vibration and Noise Reduction

*Rotor profile with feature of bilateral asymmetric are cycloidal, and with sealing ribs, to improve the reliability of operation of the compressor.

*Apply ductile iron replace steel. Its wear resistance, self-lubrication, sound insulation, and vibration damping are greatly improved.

*Apply imported mechanical seal, superior sealing performance.

*Apply high quality roller bearing take axial force from rotor, can run over 40000hours. Sliding bearing take radial force, can run over 80000hours.

*Compact unit, reasonable layout, low gravity center, reliable operating.

*All using steel valves.

*Reasonable center of gravity and anchor bolt location optimize unit vibration and noise.


Compact Piping, Stable Performance

*Add constant pressure valve in oil pipe, stability the oil supply pressure, improve the performance of the machine.

*Simple piping layout and easy to operate.
