New from Fernox is the TF1 Antifreeze Valve, specifically engineered for heat pump applications to prevent ice forming in heating and cooling systems and damaging the heat pump itself.
Manufactured from brass for a robust, durable and long-term operation, the valve is available in two sizes to suit the application – either 28mm compression or 1¼” BSP. In addition, the 1¼” BSP TF1 Antifreeze Valve is also manufactured with a 1″ BSP female connection for ease of installation on the flow and return pipes.
When temperatures drop, systems that are not treated with a glycol-based fluid can freeze within the heat pump circuit, which can result in harmful and costly damage to vulnerable components and pipework. The Fernox TF1 Antifreeze Valve reduces this risk thanks to its internal sensor, which detects when the fluid in the system is close to freezing to initiate protective action.
Specifically, when the circuit temperature drops to 3°C, typically in the event of the heat pump ceasing to circulate fluid due to a power outage or other external factor, the valve opens to discharge a small amount of fluid, allowing the circuit to drain until it returns to a temperature above 3°C, at which point the valve closes. Critically, this action prevents potential damage to the heat pump and pipework caused by the formation of ice in the system.
The TF1 Antifreeze Valve features a dual sensor thermostatic module for fast and accurate water temperature monitoring, so that the TF1 Antifreeze Valve responds to actual water temperature, not the effects of wind chill.
