2.18. Permitted cooling media
Water and mixtures of water / Antifrogen N (AFN) or water / Antifrogen L (AFL) according to the
details given in Chapter 2.17 Water quality. The following table shows the requirements for the
mix ratio of water with the antifreezes AFN or AFL. To maintain the performance of your machine
and prevent damage to components, these values must be maintained as precisely as possible.
Table 8: AFN and AFL mix ratios (or equivalent)
3. Options and accessories
The chiller can be equipped in the factory with the options described in the following.
The items marked "accessories" are enclosed with the unit, unattached, and can be reordered at
any time using the appropriate product number. The installer of the machine is responsible for
installing the accessories. You can also ask our KKT chillers Service Team to arrange for this
installation (see Table 1 Contact details).
Details of your machine's equipment are given in the separate summary documentation.
3.1. Version without tank, with pump
The Compact-Line units are also optionally available as continuous flow chillers. In this case the
units are delivered without an internal tank. The temperature sensor is then located in the
chiller's return line. If a tank open to the atmosphere is integrated on site, it is necessary to
ensure that the tank is not installed at a lower level than the chiller. Additional pressure losses
between the tank on site and integrated pump must be avoided (dp
max
=0.3bar)
3.2. Version without tank, without pump
The Compact-Line units are also optionally available as continuous flow chillers. In this case the
units are delivered without an internal tank and without pump. The temperature sensor is then
located in the chiller'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 to the pressure loss of the overall system.
