Leading manufacturer Fernox has introduced new TF1 Antifreeze Valves to its extensive portfolio of renewable products.

Available in two sizes suitable for both compression and BSP fittings, the high performance valves have been specifically engineered for heat pump applications, to prevent ice forming in heating and cooling systems and damaging the heat pump itself.

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.

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. The TF1 Antifreeze Valve features a new technology 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.

“When fluid in a heat pump system freezes, it can lead to costly repairs and unscheduled downtime, leaving the building without heat, which is always a concern for end users during the cold season,” said Mark Hall, Head Of Mechanical Engineering at Fernox. “Our new TF1 Antifreeze Valves offer a proactive and preventative solution to safeguard against such issues and is an essential component in protecting the heath of the system.”

The new TF1 Antifreeze Valves join an expanding line up of water treatment products for renewable systems from Fernox, which includes the recently launched, award-winning heat pump filter – the TF1 Sigma HP, and a range of transfer fluids and cleaners.

Established in 1964 and celebrating its 60th anniversary this year, Fernox is a leading manufacturer of water treatment chemical products, central heating system filters, plumbing consumables and diagnostic testing services. For six decades, Fernox has pioneered the development of energy efficient products both for traditional and renewable technology in domestic and commercial applications.
