Building your Project on Trust

Having expert in-house knowledge offers countless benefits to our customers including Developers, Consultants and Contractors who can benefit from the knowledge that, not only do we have a diverse range of standard fan coil units but that we have the in-house capability to design and manufacture bespoke products for any specific project application they require. 

Many of the Diffusion fan coil units have been designed to be of modular construction enabling us to create a combination of arrangements from our standard unit range. Whether your need is for slimline units and easy access for maintenance purposes in a confined space, very low sound levels to suit residential or hotel applications or meeting the lowest Specific Fan Power (SFP) levels, our Technical team have the specialist knowledge to design a unit to meet and often exceed your expectations. 

Our advanced in-house Test Facility is another huge benefit to our customers. Your chosen Diffusion fan coil unit can be set-up to accurately simulate how it would perform under your precise, often complex, specific project parameters. This delivers our customer further assurance that our product will exceed the projects criteria and enables you to invite your customer to witness the testing first-hand at our HQ in West Molesey, Surrey.  Your customer can have any technical questions answered directly by our Technical team, and Witness the product being Certified, resulting in further peace-of-mind.  The three key Witness Tests that we offer are:


Volumetric Testing and Performance
Acoustic Testing and Performance
