This product is not available in your country Images 2 Frost protection valve AAV Frost protection valve for heat pumps Variants Downloads Benefits for protecting monobloc or hydrosplit heat pumps against frost damage in the case of malfunctions or power outagehelps to avoid major damage to system componentswith integrated vacuum breakerintegrated mounting valve for easy replacement of the thermostatic elementmaintenance-free Application For applications with monobloc or hydrosplit heat pumps that are connected directly to the heating circuit water outdoors. Description A frost protection valve with integrated vacuum breaker is installed in the flow and return lines of the system. The valve must be installed as close as possible to the outdoor unit of the heat pump so that sensitive components of the heat pump are protected from damage caused by freezing of the heating circuit water. If maintenance is required, the thermostatic cartridge can be replaced, checked and reinstalled without draining the heating circuit water thanks to the integrated mounting valve. Additional information Technical data Downloads Additional information If the temperature of the medium in the heating system drops to 3 °C, the thermostatic element inside the valve opens so the medium can flow to the outside. The resulting negative pressure opens the vacuum breaker and supports the draining of components such as the heat exchanger, pipes, pumps or valves. If the temperature of the medium rises above 4 °C, the thermostatic element automatically shuts off the flow of the medium from the system.
