Screw compressors are a type of compressors that produce positive pressure in a rotational manner. These compressors are widely used to replace piston compressors in high tonnages. Creating pressure in screw compressors is a uniform and continuous process, this reduces the vibration and noise of this type of compressors in comparison with piston compressors.
Currently, these compressors are simply a piston compressor and can be used in air conditioning devices without the need for additional equipment. These chillers are under the supervision of the strict management system standards based on ISO DIN EN-ISO 9001:2008 and BS EN ISO 14001:2004 occupational health and safety management standard certificate and BS OHSAS 18001:2007 environmental management system standard certificate and the European CE standard. are produced and marketed.
The advantages of screw chillers manufactured by Damavand Pars Air Conditioning Company are summarized as follows:
