ULOC Series

Cooling System, Industrial Use, Cooling Capacity up to 60 HP, Three-Phase AC Motor, 575V, 60Hz, 25.4 GPM, No Bypass.

The ULOC Series Oil Coolers offer a compact and durable design that will provide efficient performance and long life. They provide up to 60hp of offline cooling and are suitable for most applications and environments.

This ULOC Air Oil Cooler is a stand-alone, offline cooling circuit that offers quiet operation (using a very low noise motor and gerotor pump combination), low-pressure drop and high cooling capability.

The ULOC design is also referred to in the industry as “kidney loop circuit” or “offline circuit.” It utilizes a robust bar and plate construction, providing a more efficient and compact design when compared to traditional tube and fin construction. The ULOC Series features three-phase NEMA motors, providing a wide range of available voltages and frequencies.

Features:

  • AC motor
  • Cooling up to 60 HP
  • Compact, lightweight
  • Integrated circulation pump

The system is supplied ready for installation. An integrated circulation pump makes it possible to cool and treat the oil in a separate circuit – offline cooling. Together with a wide range of accessories, the ULOC cooling system is suitable for installation in most applications and environments.
