Hydraulic versions

   KWB/KWP – Standard version (S)

Equipment with no hydraulic unit.
KWB units with a shell and tube heat exchanger and KWP units with a plate heat exchangers.
KWB/KWP units have triple protection for the heat exchanger because, as standard, they come with a flow switch, water antifreeze protection and freon antifreeze protection.

   KWB/KWP – 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 water temperatures lower than 0°C, the low temperature kit is required, which includes electrical heaters and 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.

   KWB/KWP – Version with hydraulic unit and buffer tank (H)

Hydraulic unit built into the equipment, composed of a circulation pump suitable for water or glycol water to 0ºC, a 725-litre buffer tank (except KWP-1, which is 375-litre, 725 litres optional) with an antifreeze electrical heater to reduce compressor short cycling, a 50-litre expansion vessel, bleed and stop valves, pressure gauges and a flow switch.
Optionally, a module that is separate to the unit can be supplied, with a buffer tank and electrical heaters
