The expert in manufacturing highly reliable industrial refrigeration compressors has now developed a new series of oil injection type screw compressors. Mayekawa’s new GH series is designed for different natural refrigerants, including ammonia and features a special rotor profile for higher efficiency.
Building on over 30 years of experience in designing and manufacturing screw compressors as well as screw packages, Mayekawa has now launched the GH Series of high-pressure screw compressors also suitable for ammonia refrigerant.
Product details GH series
The oil injection type screw compressors series is capable of running continuously at a discharge pressure of 5,0 MPaG (50bar). By employing a special rotor profile the GH-series enables a highly efficient operation. The compressors are designed for various gases, including ammonia, CO2, hydrocarbons helium and hydrogen.
All Mayekawa screw compressors are oil injected based on a male driven twin rotor set. Thanks to the patented rotor shapes, a high efficiency and COP can be achieved. In the new GH-series, Mayekawa is using forged steel for the rotors and tilting pads for the thrust bearings, that results in longer maintenance intervals and therefore lower running costs.
Basic technical and design specifications GH series
The 4 units of the series (160GHS, GH250S, GH250L, GH320S) range from:
Mayekawa’s commitment to the “Natural Five”
Actively addressing energy shortage and the global warming challenge, Mayekawa has shifted its focus towards the “natural five” refrigerants ammonia, hydrocarbons, carbon dioxide, water, and air. Mayekawa develops and manufactures a wide range of refrigeration systems that can be applied for heating, drying, hot water supplying, air conditioning, cooling, chilling and freezing covering a multitude of temperatures from -100°C to +200°C completely by “chemical refrigerant free” technology.
