Frequently Asked Questions

Where are ceiling and floor FCUs installed?

They can be mounted on the wall or floor below windows, or on the ceiling above doors, making them flexible for hotel rooms, shops and offices where ducting is not possible.

What capacities are available?

The range covers approximately 2-15 kW with two-pipe and four-pipe hydronic configurations.

How quiet is the unit?

Low-speed sound levels start from about 33-38 dB(A) depending on the model and mounting position.

Can the same unit provide heating and cooling?

Yes. With hydronic coils the same unit provides both heating and cooling, and an electric heater option is available for heating-only projects.

Are custom sizes available?

Yes. We offer OEM/ODM units in custom dimensions and colors for projects of 100 units or more.
