Frequently Asked Questions

What is a ground trench convector?

It is a floor-recessed fan coil installed flush with the floor, typically along glass facades, delivering heating or cooling at the glazing to prevent condensation and cold downdrafts.

Where is it commonly used?

It suits buildings with large glazed areas: office atriums, showrooms, hotels and residential floor-to-ceiling windows.

What sizes are available?

Standard trench depths range from approximately 130 mm to 180 mm, widths from 150 mm to 300 mm, and custom lengths up to 3 m per unit.

Does it provide both heating and cooling?

Yes, with 2-pipe or 4-pipe hydronic coils. The fan can be switched off for natural convection mode when no air movement is required.

Is the floor grille customizable?

Yes. Grilles are available in different materials, colors and open-area ratios to match the floor finish and project design.
