Van der Heijden 549-A-B400 chiller 20.000 Watt 16-22°C

Van der Heijden 549-A-B400 koelthermostaat 20.000 Watt

KÜHLMOBIL 16kW to 38.5kW - Powerful workhorse

A range of more powerful cooling units, these models of cooling unit are also mobile units with plug-in connections.   For reducing the operating cycles per hour the tank size is 225 or 250 litres. The containers are easy to fill thanks to the large screw cover filling holes on the top of each cooling unit. Evaporation rates are very low.
Since the heat emitted from units of this size can be very considerable (warming of more than 40% to the surrounding area), these units are frequently installed outside, in technical areas or even in large fields. The amortisation times are relatively short since the KÜHLMOBIL saves significant amounts of water per year. 

Rear View.  This application shows a version with a manual bypass. Automatic bypass is available as an option.  In applications where the water flow is on/off via magnetic valves, the automatic bypass will open when the application valve is closed and water will flow in a short circuit, avoiding pump damage and limiting the maximum pressure.  The required opening pressure can be factory set for you, however, easy access into the unit allows for the user to make adjustments for higher or lower pressure easily.

All the variants are also possible on these versions.

The chiller can be supplied as an air or water cooled version.  Other temperature ranges and pumps are available.  Many other options and accessories are available, please see the accessories and options section.
