Compact liquid-air cooling system with tank and pump

FLK series - in the power range from 1.1 to 10.5 kW

When cooling the process medium in the temperature range above 25 °C, the air convection cooling of the FLK cooler is an energy-saving alternative to compression cooling.

The circulating pump conveys the circulating medium over the component to be cooled back to the
DELTATHERM® liquid-air cooler. The series is ready for connection and has been tested for function and leaks.

For frost-free indoor installation.

Main applications of the FLK systems are:

Liquid-cooled motor spindles
Liquid-cooled drives
Liquid-cooled torque motors
Liquid-cooled servomotors
Liquid-cooled linear motors
Liquid-cooled converters
Liquid-cooled bearings
Liquid-cooled tools
Liquid-cooled welding systems
Liquid-cooled X-ray systems
Liquid-cooled CT or MRI systems
