Options and accessories
The chiller can be equipped in the factory with the options described in the following.
The positions marked with "accessory" are included with the device, unattached, and can be re-ordered at
any time with the respective product number. The installation of the accessory is the responsibility of the
installer of the machine. You can also ask our KKT chillers Service Team to arrange for this installation (see
Contact details
).
Information on the features of your machine can be found in the separately enclosed summary
documentation.
3.1.
Heater for the compressor and control cabinet
The oil sump heater prevents the deposit of refrigerant in the oil when the temperature is low. When the
compressor is started up this refrigerant would be liberated from the oil as gas and make the oil foam up.
Under these conditions the lubrication of components subject to friction in the compressor would be poor,
which could lead to the damage of the compressor.
The control cabinet heater is thermostatically controlled and prevents moisture from the drawn-in ambient
air in the event of lower ambient temperatures from condensing on electrical and electronic components of
the control cabinet and hence from damaging them.
To enable the activation of both heaters, the chiller may not be disconnected from the power supply (
Chapter
8.2 Selecting the operating mode
).
ATTENTION! The water - glycol mixture ratios specified in the Technical Data Chapter
1.2 must always be observed
Do not use mixtures of different anti-freeze products. This can lead to undesired
chemical reactions as well as silting.
