ESBE VTN102 Anti Freeze Valve

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 heat pump and plate heat exchanger should not freeze and break. When the fluid temperature drops below 3°C, the valve starts evacuating water allowing warmer water to reach the valve, as it closes again at a fluid temperature of 4°C.

• Fluid temperature range: 0-90°C
• Opening temperature: 3°C
• Max. discharge flow: 2 l/min @3 bar ΔP
• Exact temperature regulation
• Robust
• Maintenance free
