Originally known as The Heywood Compressor Co, founded in Glover Street, Redditch, Worcestershire, it was renamed The Hymatic Engineering Co. in 1946. The company designed and produced portable and stationary air compressors and valves supplying the Royal Air Force in the 1950s.

Around 1952 it was acquired by Chloride and by 1957 was a subsidary of Chloride Electrical Storage Co.

By 1973, the company was involved in cryogenics, systems engineering, aircraft and missile equipment, precision control valves, and other products and was taken over by Huntleigh Investments in 1974.

Now owned by Honeywell, Honeywell Hymatic is a maker of high tech equipment for the defence and aerospace sectors.
