water and antifreeze protection for freon.

   KWA/KWM – Version with hydraulic unit (P)

Integrated hydraulic unit composed of a circulation pump suitable for water or glycol water to 0°C, bleed and stop valves, pressure gauges and a flow switch.
For temperatures lower than 0°C, the low temperature kit is required, which includes electrical heaters in the hydraulic elements, insulation on the heat
exchanger, water piping and expansion vessel and a replacement pump for small models. This kit allows it to work with water down to -10ºC.
