What the work involves
Typical jobs are fit-outs and refurbishments: a new tenant needs ventilation to match a new layout, an old system cannot keep up with more staff, or a change of use needs a fresh design. We can work directly for occupiers and landlords, or as a subcontractor to fit-out and building contractors.
Design and build or install-only
We design it, or install to a consultant's drawings.
Heat recovery supply and extract
One or more units with ductwork to diffusers, sized for occupancy.
