Wadsworth Controls has greenhouse operating controllers from simple heat and cooling to very complex total environmental systems for large multi hectare greenhouses. USGR has installed Wadsworth Control Systems to operate our equipment in numerous institutions, government facilities, Botanical Gardens. We strongly urge all of our clients to consider the Wadsworth controls and energy curtains because they are almost maintenance free, long life and operate with amazing degrees of accuracy. Testament to this is Wadsworth controls that USGR installed in a 50,000 sq ft greenhouse in Lhasa, Tibet in 1980. Spare parts were not called for until 1999.
