 Dedicated to providing the information you need

Our dedicated R+D and Test facilities complement our in-house design and manufacturing capability to meet requirements placed by the most demanding customers.

Our combination of real-world simulation, expert staff and certified test equipment means you can be confident that all Diffusion units will perform according to plan in their target environments.

Using instruments calibrated and certified by BSRIA, we measure air volume, thermal and acoustic performance:

 Validating Air Volume Performance

Air volumes are measured on a purpose designed flow-measuring rig utilising duct mounted flow measurement equipment. The rig measures air volume, motor amps, motor power and power factor simultaneously. Units can be mounted on the rig with the project ductwork and grilles fitted to give an accurate measurement of actual site external pressure drop.

 Validating Acoustic Performance

The acoustic test lab consists of two 4mx4mx4m (64m3) reverberation chambers positioned end-to-end to allow measurements of the inlet/casing radiated and discharge levels simultaneously using full octave band sound measuring equipment.

The chambers can also accept the ductwork and grille layouts for a specific project to be fitted to the unit under test, so an ‘as installed on site’ scenario can be accurately acoustically measured.

 Validating Thermal Performance

The thermal test lab consists of a computer controlled thermal test system to accurately simulate the internal load conditions required for a given project.

The system also controls the operating parameters of the unit under test with regards to water flow rates, air volume and external pressure drop. It can be used for both heating and cooling in airside and waterside control formats. Heat exchanger pressure drops can also be measured and recorded, and all results are made available as comprehensive hardcopy output.
