Water Cooling
Refrigeration may contaminate the cooling water if a leak occurs.
➤ A special heat exchanger must be used for heating drinking water.
The specific heat capacity and required volume flow rate of the cooling water changes if anti‐
freeze is added.
➤ Consult an authorized KAESER service representative to ensure optimum cooling-sys‐
tem performance.
➤ Comply with the specified minimum requirements for the cooling water in order to avoid
downtimes due to corrosion, calcification and contamination.
It is imperative that measures for cooling water treatment and filtration are implemented and
performed.
KAESER can provide the names of companies specializing in cooling water analysis and the
supply of suitable treatment devices.
The following design types are available:
■ Option K2: Water cooling with plate heat exchanger: Chapter 2.8.1
Open cooling system
An open cooling system may be a cooling circuit with open cooling towers for cooling via evapora‐
tion. As a portion of the cooling water evaporates, it must be replenished regularly. During evapora‐
tion, the material content of the cooling water concentrates and the contact with ambient air can
contaminate the cooling water. When replenishing cooling water, you must ensure the minimum re‐
quirements for the cooling water.
Closed cooling system
In a closed cooling system, the cooling water has not contact with the atmosphere. Thus, it cannot
be contaminated by the atmosphere or enriched with oxygen, for example.
Continuous-flow cooling system
A continuous-flow cooling system is an open cooling system. Ground, surface or drinking water cir‐
culate once through the cooling system.
Further information The dimensional drawing in chapter 13.1 gives the flow direction, size and position of the connec‐
tion ports.
