Appendix 1: Water cooled condenser option
The water-cooled condenser option is available as an alternative to the air-cooled standard
version.
Chillers with a water-cooled condenser require an in-house cooling water supply, which
meets the following recommended specifications:
10 litres/minute
1 bar minimum differential pressure across chiller
25C maximum temperature, but lower is better
The modulation valve, which can be found behind the front grille of the chiller does not
require adjustment. It is factory set to control the refrigeration system at an optimum
pressure and temperature.
Coolant and house water connections
There are two pairs of water connections on the rear of water-cooled chillers. The left hand
pair are the recirculating coolant connections; these are the connections for the coolant
supply to your application. The right hand pair are the connections for the house water
supply.
Standard configuration for both coolant and house water is
Inlet Right
Outlet Left
with respect to the chiller unit.
All other operation features are the same as those described in the main body of this
manual.
