Hydraulic versions:
KWE – Standard version (S)
Equipment with no hydraulic unit. The KWE equipment has triple protection of the plate heat exchanger because, as standard, it comes with a flow switch in the water piping, water antifreeze protection and freon antifreeze protection.KWE – 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 flow 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°CKWE – Version with hydraulic unit and buffer tank (H)
Equipment designed with a hydraulic unit in addition to a buffer 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 buffer tank and antifreeze resistors. For water temperatures below 0°C, it is necessary to request the low-temperature kit for the hydraulic unit.
