Chillers for water
Project planning
Chillers may be used in all situations where a high cooling
load is required, e.g. in process and machine cooling, in
media cooling or when dissipating heat loss from enclosures
via air/water heat exchangers.
Our project engineers will be happy to help you design a
chiller for your specific application area. An overview of the
planning data required for this purpose can also be found
on the Internet at www.rittal.com.
The cooling output is calculated from the heat loss of the
components to be cooled. This can be calculated using
volumetric flow and temperature difference.

= Cooling output kW
V
= Volume flow [l/min]
ΔT = Temperature difference [K]
c = Specific thermal capacity [kJ/kg  K]

Design of chillers
The Therm software takes care of the time-consuming calcu-
lation of the required cooling output, allowing you to design
the optimum chiller.
