The ESBE series VTN100 is a range of safety valves for mono bloc heat pumps to ensure that in case of a power outage during cold weather, the heatpump and plate heat exchanger should not freeze and break. When the media temperature drops below 3°C, the valve starts evacuating water allowing warmer water to reach the valve, as it closes again at a media temperature of 4°C.
