3.20. Phase monitoring
Optionally, the Vario-Line units can be equipped with so-called phase monitoring. This monitors the
phase sequence, phase failure, undervoltage and asymmetry and covers a voltage range of 200-
690V. If the respective predefined limits are exceeded the system switches off and protects the
electrical components installed in the unit.
3.21. Output control < ±0.5K
If more precise setpoint constancy than ±0.5 Kelvin is required, the chiller can be equipped with
output control. Here the output of the refrigeration circuit is adjusted to the refrigeration demand
by an electronically controlled valve.
3.22. UL version
The main components of the Vario-Line are already designed to conform to UL in the basic fitout. If
your unit is ordered with the UL version option, the control cabinet is also produced in accordance
with the UL regulations. The corresponding UL certificate must then be issued separately within the
scope of the official UL acceptance – please ask your customer consultant.
3.23. Special paint finish
All façade panels (see Chapter 1.2 Elements ) can also be optionally supplied with a special paint
finish.
3.24. Air filter mat (accessory)
If the chiller is operated in an environment contaminated with dust or oil vapour, the condenser
should be protected with the air filter mat. The filter is fixed in place using the Velcro tapes attached
in the condenser safety grille. The filter is removed for cleaning and is washed out with water or a
mild lye (alkaline solution). Highly soiled filters must be replaced by a new filter. Please contact the
KKT chillers service team (

3.25. Vario Foot (accessory)
The four levelling feet of the Vario Foot can be used for rolling, vibration isolation and for height
adjustment. To do this, the height of each foot can be individually adjusted up or down using a
special ratchet function. If the unit is out of service, all four feet can be screwed in until the unit
stands on the integrated machine rollers and can be rolled away.
3.26. Level package (accessory)
The level package is used if the application is to be installed more than 500 mm above the chiller
(see also
Chapter 6.2.7 Process level) . This option is delivered separately with the unit (i.e. is not
installed) and consists of an electrically activated valve and a check valve. The electrically activated
valve is to be installed at the unit inlet, the check valve at the unit outlet. The valve is installed
electrically in the control cabinet as shown in the electric circuit diagram.
