Boesch Oil Sentinel
The Boesch Oil Sentinel is used in elevator sump pits, transformer vaults and industrial sumps to remove water while retaining oil and other hydrocarbons. There is no need for an oil-water separator. The Boesch Oil Sentinel is a UL listed system.

OIL SENTINEL OPERATION:
Water and oil fill the elevator sump pit. As the sump is filling, the oil will float on top of the water. This layer of oil will not be pumped from the tank. The water underneath the oil will be pumped out through the discharge pipe to the sewer or other proper disposal area.
