Frequently Asked Questions

What is a ducted fan coil unit?

A ducted FCU is concealed above the ceiling and distributes conditioned air through ductwork, providing invisible, uniform comfort for offices, hotels, shops and homes.

What static pressures are available?

Standard concealed units offer around 30-80 Pa, while high-static-pressure models reach approximately 120-200 Pa for long or complex duct runs in commercial buildings.

How thin can concealed units be?

Ultra-thin models are as low as about 200-230 mm in height, allowing installation in shallow ceiling plenums without lowering the ceiling.

Can units provide heating as well as cooling?

Yes. Options include 2-pipe and 4-pipe hydronic coils, electric heater kits and hot-water coils to match the heating source available at the project.

Do you supply duct accessories and controls?

We supply flexible ducts, grilles, filters, wired or wireless controllers, and BMS interfaces as part of complete project packages.
