SRM Open-type Single- stage Screw Compressors include 6 series totaling 19 models. Displacement 265- 10850m3/h（2960RPM）,discharge temperature - 45℃ - +20℃ , applicable for the natural and environment-friendly refrigerants such as R717, R404A, R507A, etc.Stepless (10%- 100%) capacity control: intelligent controller with accurate selection and rapid response to ensure to operate in high EERunder different working conditions. The designed obliquity >30° , which is also applicable to the refrigeration systems on the marine units. SRS Semi-hermetic Single- stage Screw Compressors include 20 models, displacement 85- 850m3/h (50Hz), designedpressure 2.8Mpa，applicable for R717. Compact structure, easy maintenance, low vibration and noise, zero leak of refrigerant.The compressor is packaged with the permanent magnet synchronous variable frequency motor, which regulates the rotorspeed to improve the operation efficiency of the compressor. SRH Series Open- type High- pressure Screw Compressors include 7 series totaling 14 models, displacement 25- 2770m3/h(2960RPM), designed pressure 6.3Mpa. The high pressure design of the compressor can be applied to high- temp heat pumpwith NH3, also applicable for CO2/NH3 cascade refrigeration system for the low- temp refrigeration SP RefComp Semi- hermetic piston compressors are widely used not only in commercial and industrial refrigeration, but alsoin certain special air conditioning conditions. RefComp SP Series compressors have a wide applicability, good in variousrefrigeration conditions. Despite the already mature and reliable technology in making piston compressors, RefComp stilldiligently researches and innovates to further improve the piston compressors' performance such as quality and reliability.RefComp SP series include 34 models, with 2, 4, 6, 8 cylinders, rated power ranging from 3 to 70 HP. SB RefComp SB Series includes 6 models. High-pressure displacement: 27.6- 51.5m3/h, Power: 12- 30HP, Applicability: R22,R404A and R507, Features: high efficiency, long durability, compact size and low vibration, etc.. The two- stage displacementis achieved through two consecutive compressions. In Stage I, the refrigerant gas from the evaporator is sucked from theinlet into the intermediate cavity. in Stage II, the refrigerant gas is sucked in from the intermediate cavity and is compressed tothe displacement pressure. Compared to the single- stage compressor, the compression ratio of each stage of the two-stagecompressor is always lower. as a result, the displacement temperature is lowered and efficiency is improved. RefComp SRC- S Series include 18 models, applicable in the refrigeration conditions of medium and high evaporatingtemperatures. SRC- S compressors are characterized by embedded oil separator, compact design, easy installation, lownoise, high efficiency, etc.. They can be best configured in line with various applications and conditions, e.g.full- flooded normaltemperature/high- temperature heat pump and water chiller.
