Extend the Life of your Hydraulic Elevator System!

Avoid hot oil problems like nuisance shutdowns, leveling problem and oil odor by installing the MEI- BOL Oil Cooler.
Designed to be mounted in a remote location in order to connect to the duct/ventilation system of the building


  • Smoother stops and starts
  • Extended component life
  • Fewer shutdowns
  • Overall performance improvement
  • Filters oil

Recommended Applications

  • Twin jack holeless applications with two- or three-stage telescopic jacks.
  • Heavily used single-stage twin jack holeless projects.
  • Roped hydraulic applications with moderate usage and travel exceeding 25 feet.
  • Any hydraulic elevator with high usage.

How It Works

This Oil Cooler is designed to be mounted in a remote location* in order to connect to the duct/ventilation system of the building. When the oil temperature in the reservoir reaches a preset limit, it is circulated through the radiator. This process reduces the oil temperature by nearly 40°F, depending on site conditions. The oil is also filtered as it runs through the system, which results in enhanced performance and extended component life.

*Remote location must be within 110 feet horizontally or 55 feet vertically from the power unit. Piping, wiring, and conduit to remote location are not included.

*MEI recommends our Cold Weather Kit (Part No. 19919) when your heat exchanger is installed where the temperature gets below 50°F
