KWG – Standard version (S)

Equipment with no hydraulic unit . The KWG equipment has triple protection of the plate heat exchanger because, as standard, it comes with a fl ow switch in the water piping, water antifreeze protection and freon antifreeze protection.

   KWG – Version with hydraulic unit (P)

Integrated 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.

   KWG – 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 unit’s chassis in all models. H version in series 4 and 6 does not alter the dimensions of a standard unit.

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)
