Varec Biogas

Varec (VApor RECovery Specialty Company) began business in the 1930's at its manufacturing plant in Compton, California. Varec was there in the infancy stage of the biogas market in the early 1950's. From the onset, Varec's focus was to deliver Biogas Handling products that suited customers' specific requirements, even if it meant creating the product off the drawing board. Varec initially sold direct to end-users and in the 1970's instituted a Sales Representative Network that catered to Municipal Wastewater Treatment Plants. A select number of Sales Representatives in the United States helped Varec acquire approximately 90% installed base from the 2,500 Wastewater Treatment Plants that utilize Anaerobic Digesters for Biosolids Treatment built between the mid-60's to late 70's. Today, Varec Biogas is 100% dedicated in providing total solutions to the biogas market. In February, 2003, Westech Industrial Inc. acquired the biogas portion of the Varec business from Tyco Valves and Controls, LP Inc.
