APPLICATION

Used in heating and cooling systems with air source heat pump monoblock type. Mounted on the return

and supply pipe of the system, as close as possible to the heat pump outdoor unit, outside the building.

Protects the internal components of the heat pump and the system from damage due to freezing of the

medium in the system.

WORKING PRINCIPLE

In a system with a monoblock air source heat pump, during a loss of circulation (e.g., due to a power

failure), the medium in the installation may freeze at sub-zero ambient temperatures. The created ice can

damage the heat pump heat exchanger and other sensitive installation components. When the tempera-

ture of the medium in the system drops to 3°C, the thermostatic element inside the valve will open the

flow of the medium to the outside, preventing potential damage. When the temperature of the medium

rises above 4°C, the thermostatic element will automatically close the flow of medium from the system.
