Liquid ring compressors LOH 20103, LOH 20107 - 1

Liquid ring compressors LOH 20103, LOH 20107 VACUUM TECHNOLOGY KPH K 2 133.72110.53.01 E 03/2002 Compression pressures: 0,2 to 1 bar Suction volume flow: 18 to 51 m³/h CONSTRUCTION TYPE Sterling SIHI liquid ring compressors are displacement compressors of simple and robust construction. They have the following important features: Handling of nearly all gases and vapours non-polluting due to nearly isothermal compression oil-free, as no lubrication in the working chamber additional liquid can be handled with the gas flow easy in maintenance and reliable operation low noise and nearly free of vibrations wide choice of material, therefore applicable nearly everywhere no metallic contact of the rotating parts The Sterling SIHI liquid ring compressors LOH 20103 and LOH 20107 are single-stage compressors. They can be applied without modification as vacuum pump up to a suction pressure of 150 mbar see catalogue part LI). APPLICATION Handling and compressing of dry and humid gases; entrained liquid can be handled during normal duty. The compressors are applied in all fields where a compression over pressure of up to 1 bar has to be created by robust compressors and only a small increase in temperature is admissible during compression. Fields of application are e.g.: - the plastics industry, for the recovery of process gases as vinyl chloride - the petrochemical industry, for the compression of combustible gases as gasoline vapours or hydrogen - transport of gases in general, e.g. to a reactor NOTE During operation the compressor must continuously be supplied with service liquid, normally water, in order to eliminate the heat resulting from the gas compression and in order to replenish the liquid ring, because part of the liquid is leaving the compressor together with the gas. This liquid can be separated from the gas in a pressure liquid separator ( see catalogue part accessories). It is possible to reuse the service liquid. The direction of rotation is clockwise, when looking from the drive on the pump.
