Fernox launches dedicated filter for heat pumps 

Fernox has extended its portfolio with the new TF1 Sigma HP Filter, a product which has been specifically designed to protect air and ground source heat pumps.  

The company has developed the new TF1 Sigma HP Filter to offer what it describes as “the best possible protection”. The filter’s shape allows for the efficient capture of system debris and the settlement of particles within the main body of the filter. The unit is manufactured from engineering-grade polymer. 

Key to its performance is the utilisation of flow and filtration technology (patent pending), which allows the filter to capture all types of debris, including magnetite, hematite and scale – at high flow rates (up to 80 L/M) typical of heat pump installations.  

The Fernox TF1 Sigma HP Filter is supplied with 22mm or 28mm full-bore valves as standard. The design of these valves means that there is no restriction of flow through the filter assembly, ensuring the heat pump can maintain the required COP (Co-efficient of Performance).  

Due to its double radial seal between the manifold and main filter body, the Fernox TF1 Sigma HP Filter is flexible. Installation is said to be quick and simple, enabling horizontal or vertical orientations or at any point around a full 360° pipework orientation.  

Similar to the design of other products in the Fernox TF1 range, the TF1 Sigma HP Filter is engineered as a sealed unit without a lid for greater integrity and security, reducing any potential for leaks.  

Greg Banham, UK & Ireland Sales Director at Fernox noted: “The TF1 Sigma HP Filter has been extensively tested, proving it has the best Kv value of any available filter on the market. A combination of features including the unique, patent-pending filtration technology and the low-pressure loss from the carefully engineered flow paths mean that COP levels and heat pump efficiency can be maintained. Furthermore, the use of high integrity and high-quality components ensures that the Fernox TF1 Sigma HP Filter provides unparalleled performance.”
