Air handling units
for general
(non-pool) applications.

The ‘WD General’ range of air handling units are designed for non pool applications such as general commercial development.

The ‘WD’ range are high quality but affordable air handling units, available in a variety of specifications & flexible configurations e.g. horizontal, double stacked, side by side or vertical arrangements. 

We also have a ‘WD Healthcare’ range designed specifically for hospitals, clinics & NHS & Private Practice healthcare applications; and ‘WD Packaged Heat Recovery units’, which are compact & efficient and factory wired for ‘plug & play’ installation. 

The ‘WD’ range feature excellent quality door furniture & low leakage door seals, weatherproof options and many optional features. 

The selection software allows us to tailor the air handling units to your precise project requirements and quotations include detailed drawings (pdf &/or CAD format) and easy to read technical data sheets.
