We have been manufacturing API oil water separators since the 1930’s, when we worked with the American Petroleum Institute (API) to develop the industry’s standard design. Our API separator design has been risk-assessed, assuring safe operation. Above ground, steel tankage provides double-containment and visual leak detection for hazardous sludges and wastewater, and VOCs are contained through the use of vapor-tight covers. Additional safety features include non-metallic collector components and covers, stainless steel on all wearing metallic components, deflagration vents, flame arrestors, and more.
