LACT Systems

Envirosep’s LACT Units are certified engineered and manufactured skidded systems used for the accurate measurement and transfer of petroleum products from the production site to trucks, pipelines, or storage tanks. Envirosep utilizes the most reliable system components, from leading manufacturers, to provide the most precise and dependable system design. Our LACT Units come in standard 2″, 3″ and 4″ skids or can be customized for your specific needs.
