3. Options and accessories
The chiller can be equipped in the factory with the options described in the following.
The items marked with "accessory" are enclosed with the unit and can also be ordered later at any
time under the relevant product number. The installer of the machine is responsible for installation
of the accessory. You can also ask our KKT chillers service team to carry out this installation (see
Table 1: Contact details ).
Details of your machine fitout are given in the separate quick start documentation.
3.1. Version without tank, with pump
The Vario-Line units are optionally available as continuous flow coolers. The units are delivered
without an internal tank in the unit. The temperature sensor is then located in the cooler's return
line. If a tank open to the atmosphere is integrated on site, ensure that the tank is not installed at
a lower geodetic level than the cooler. Additional pressure losses between the tank provided on
site and the integrated pump are to be avoided (dp
max
=0.3bar)
3.2. Version without tank, without pump
The Vario-Line units are optionally available as continuous flow coolers. The units are delivered
without an internal tank in the unit and without a pump. The temperature sensor is then located in
the cooler's return line. The cold water is then circulated via the evaporator by a pump to be
installed on site. This must at least be designed for the pressure loss of the whole system.
3.3. Version with water-cooled condenser
While the basic variant of the Vario-Line has an air-cooled condenser, it is also possible to purchase
the individual units in this series with water-cooled condensers.
Figure 3: C6848 Refrigeration diagram
The condensers used are plate heat exchangers, whose stainless steel plates are copper soldered.
The 3-way valve is located in the cooling water outlet and is controlled via a servomotor according
to the condensation pressure. By closing the additional bypass valve provided it is possible to switch
from 3-way to 2-way control.
