KHL Oil Level Controller


Operating Principle:
KHL,Oil,Level,Controller,Kenco,EngineeringKENCO Oil Level Controllers are designed to control a constant oil level in the crankcase of stationary engines, compressors, and mechanical lubricator boxes. The KENCO oil controller works in conjunction with an overhead oil supply system which feeds the oil level controller. As the oil is consumed, the oil controller supplies the required amount of oil to maintain a proper level in the crankcase. The oil controller maintains the proper amount of oil in the crankcase by using a float controlled valve. The valve opens and closes as oil is needed in the crankcase to provide a constant oil level.

The oil level switch in the KHL is an electric switch in an explosion proof enclosure, rated for hazardous hydrogen gas environments. The float switch monitors the oil in the crankcase. The level within the crankcase directly corresponds with the oil level in the oil level controller housing. If the oil level in the crankcase drops or rises 3/4" past the centerline, the switch will trip sending an alarm.


  • Locations where high and low levels will be monitored by one alarm

  • Hazardous locations where flammable or combustible elements are present.

  • Stationary engines and compressors

  • Mechanical lubricators

  • Pumps


  • Reduces maintenance by maintaining a constant lube level.

  • Protects against lubrication failure

  • Group B explosion proof certification for hydrogen gas atmospheres

  • Controller mechanism fully removable without draining oil

  • Easy view convex sight window

  • High pressure applications up to 70psi

  • Fire Safe Valves Available

  • Oil inlet allows for piping configuration from any direction

  • Oil outlets on either side of housing and in the bottom to allow for various piping configurations

  • Easy access to switch float through 3/8" vent hole in top of housing for simple testing of switch operation

  • Direct mount adapters eliminate equalizing problems and reduce installation costs

  • Oil level controllers for synthetic oil applications now available
