Diffusion, the heating and cooling equipment specialist, has been acquired by the Volution Group plc, a leading supplier of ventilation products to the residential and commercial construction market in the UK and northern Europe.

Volution Group plc completed the acquisition at the end of December, with Diffusion joining some of Group’s top brands including Vent-Axia.

A company with great British heritage, Diffusion has been manufacturing heating and cooling equipment in the UK for more than 50 years. Its product portfolio comprises a wide range of fan coil units, air curtains, fan convectors and general purpose heaters. In addition to its standard product range, it also offers a specialised bespoke product service aimed primarily at end-users, architects and consultants.

Now that Diffusion and Vent-Axia are part of the same group specifiers will have access to both brands together.

Mark Hoskins, UK Ventilation Group managing director, said: “There is a great synergy between Vent-Axia and Diffusion, with a strong heritage of British manufacturing and provision of excellent products to the market. Specifiers can now take simple steps to building services specification, knowing that they can find a wide range of quality products in one place.”

Together, Diffusion and Vent-Axia’s product development programme focuses on their energy saving initiatives, using technology which reduces power consumption and, wherever possible, recovers, recycles and re-uses energy that would otherwise be wasted.
