KWE – Standard version (S)

Equipment with no hydraulic unit. The KWE equipment has triple protection of the plate heat exchanger. The series production version includes a flow switch, antifreeze protection for water and antifreeze protection for freon.

   KWE – Version with hydraulic unit (P)

Hydraulic unit composed of a circulation pump suitable for water or glycol water to 0°C, expansion vessel,
bleed and stop valves, pressure gauges and a fl ow switch.
For water temperatures lower than 0°C, the low temperature kit is required, which requires replacement of the pump and adds electrical resistors to
the hydraulic elements for work with water temperatures as low as -10°C.

   KWE – Version with hydraulic unit and buffer tank (H)

Equipment designed with a hydraulic unit in addition to a buff er tank with an antifreeze
electrical heater to reduce compressor short cycling.
The hydraulic unit is built into the very chassis of the equipment in all models except for series 6, where the hydraulic unit is in a separate module but
is delivered with the equipment.
Optionally, a module independent to the equipment may be delivered, with a 375 or 725 litre capacity buff er tank and antifreeze resistors.
For water temperatures below 0°C, it is necessary to request the low-temperature kit for the hydraulic unit (see module dimensions)
