GSGR GS15031-202 AL20

Air Cooled (air-to-oil), Nominal Heat Rejection: 11 HP, with Filtration and Gauge.

The GS Global Resources GS15031-202 AL20 Offline Cooling System allows for cooling of gearboxes and reservoir solutions without impacting existing plumbing of the system.

  • Cooler is a compact system for removing approximately 11 plus HP of heat continuously from hydraulic or lubrication system
  • Small compact size cooling solution allows for installation in tight areas and is ready to install
  • Compact solution utilizes proven air cooler cores allowing for cooling of thick lube oils
  • System comes with thermal bypass valve and is protected from over pressure
  • Three-phase multi voltage premium efficient dual shafted motor is rated for outdoor use which allows the cooling system to be installed in most applications
  • Double shafted motor solution with gear pump allows for pumping of fluids from ISO150 to ISO320
  • Gear pump has double shaft seal for pumping of very thick fluid
  • Pump is designed for high vacuum inlet condition
  • System has a 25-micron filter for cleaning the oil while cooling
  • Bypass valve allows for element replacement while system is running with no interruption
  • + expand all
  • - collapse all
