Designer and manufacturer of the largest range of twin rotary screw compressors in the world for refrigeration and gas gathering.

Howden™ screw compressors

Howden screw compressors are manufactured to exacting standards and supplied to distributors worldwide. In addition to supplying bare shaft units, Howden provides complete screw compressor systems engineered for specific installations.

Screw compression technology was developed by James Howden & Co. and Professor Lysholm of Svenska Rotor Maskiner in 1939. Howden Compressors commercialised this novel technology during the 1940s and developed the world's first oil-injected controlled-capacity compressors in 1961. Howden has been providing screw compressors to the refrigeration, oil, gas and petrochemical industries world-wide ever since.

Howden's compressor design with its low maintenance and high efficiency minimises operating costs. The smooth running action of the twin screws enables the compressors to handle the most difficult gases, contaminants or liquid slugs without vibration. Howden supplies two series of bare shaft standard screw compressor units, the XRV and WRV ranges. The XRV supplies flows from 300m3/h to 1600m3/h, and the WRV from 550m3/h to 12,000m3/h.

Should more than a bare shaft compressor be required, Howden will engineer a full compressor system. A typical package incorporates compressor, driver, oil management system, controls, instrumentation and additional process components such as coolers, knock out vessels, condensate removal system and scrubbers. Howden normally delivers each package as a fully assembled unit ready to link to the customer's process and utility interfaces, thus minimising the installation and commissioning period. Attention is paid to ensure that maintenance access is fully taken into account.

Howden's customised package sets are designed to comply with the requirements of international standards such as API, ASME (VIII DIV 1), BS, GOST, AD, MERKBLATT, Chinese and Japanese pressure vessel codes, NORSOK, NACE, and TEMA, when specified. In addition, Howden's compressor systems and the installations are accepted by many major authorities such as Lloyds, Bureau Veritas, Norske Veritas, RINA, DSRK, Bureau do Mines, Germanischer Lloyd and NKK.
