Filter works with air and ground source

Now available from Fernox is a dedicated filter for air and ground source heat pump systems. The TF1 Sigma HP Filter’s shape allows for the efficient capture of system debris and the settlement of particles within the main body of the filter. Manufactured from engineering-grade polymer, the TF1 Sigma HP Filter is said to provide excellent strength and hydrolysis resistance.

Key to its performance is Fernox’s flow and filtration technology, which allows the filter to be effective at capturing 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 22 or 28mm full-bore valves as standard. The design of these valves is crucial as it means that there is no restriction of flow through the filter assembly, ensuring the heat pump can maintain the required CoP.

The sealed unit comes without a lid for greater integrity and security, reducing any potential for leaks. Fast and simple to service, unlike lidded filters, there is no need for replacement ‘O’ ring seals, minimising ongoing maintenance costs.
