HD Series Reciprocating Gas Compressors HD080, HD160, HD170, HD340, HD360, HD370, HD600, HD610, HD640, HD940

The HD Series Reciprocating Gas Compressors provide efficient and quiet delivery of oil-free gas or air. Single and two-stage compressors combine advanced design technology and state-of-the-art materials to deliver maximum performance with minimum maintenance. With a variety of options and models, these compressors are highly customizable and can be set up to meet the exact specifications for application requirements. 

The ductile iron and stainless steel materials used in these compressors provide toughness and strength that helps extend compressor life under all operating conditions. The HD Series Reciprocating Gas Compressors are available in two model types - HD and HDL - and a variety of sizes. The HD air-cooled models are suitable for most applications, especially for operation at lower compression ratios and for liquefied gas transfer applications. HDL models have a liquid-cooled head and cylinder for more demanding applications.
