Van der Heijden 121-A-RB400 koelthermostaat 2.100 Watt

KÜHLMOBIL 1.2kW to 2.9kW

A powerful but quiet, small circulatory cooler available in different cooling powers. A cooling unit cools the circulating water and/or antifreeze mixture in a small container, from where it is supplied to the cooling unit by a circulation pump.

The 15 or 25L container is easily accessible and can be filled from under the hinged cover on the top of the unit.

This type of unit is supplied with a 3.5 or 4.5 bar pump with up to 10 or 40 l/min.  Other pump pressures or temperature ranges are available. The chiller can be supplied as an air or water cooled version.  .  Many other options and accessories are available, please see the accessories and options section.  The air inlet is on the front face.
