The KZB units feature triple protection for the plate heat exchanger. The series production version includes a flow switch, antifreeze protection for water and antifreeze protection for freon.


   KZB – Version with hydraulic unit (P)

Hydraulic unit composed of a circulating 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°C.
