Refrigeration compressors, refrigeration one unit, air-conditioning compressor, the global hot selling! British technology, professional-quality, newly designed third-generation semi-hermetic screw compressor refrigerator, small size, high cooling capacity, energy efficiency ratio. ● rotor using the latest British Holroyd asymmetric screw profile, good liquidity, high efficiency. Optimized design, the film is easily formed tooth surface, while the choice of rigidity and good wear resistance of AISI standard US special screw rotor material, thus ensuring rotor wear, particularly long life. ● into the compressor motor, double body structure and specially designed exhaust chamber and a built-in oil separator, so that the noise is extremely small. Screw compressor rotor is a simple rotary motion, and therefore compressor vibration is particularly small. Noise and vibration Found British Society confirmed Laoai Shi were 75dB (A) and 5u. Capacity range: 125kW ~ 905kW ● semi-hermetic screw compressors, using the new multi-energy regulation, each compressor energy adjustment range: 50%, 75% and 100%. Smooth start-up mode specifically designed starting current, starting torque, the impact on small power, does not interfere with the normal operation of other equipment.
