TROX HESCO displacement flow diffusers offer a variety of different shapes and guarantee an optimum compliance with all kinds of architectural demands. Depending on the customers’ requirements, bespoke designs supplement the large range of standard versions.

The displacement flow diffusers provide optimum comfort conditions combined with excellent acoustics and a uniform velocity profile over the entire outlet.

Special geometrically arranged plastic nozzles with integral air deflectors scoops guarantee that no maintenance is required.

Simple and quick selection and design of displacement flow diffusers is possible with the TROX design program “Easy Product Finder”.

TROX displacement diffusers of the QLK series are employed primarily in the commercial sector.
The cool supply air is introduced into the room at low discharge velocities and very low turbulence, according to the displacement principle.

The series comprises 3 different variants in highly tasteful design.

TROX displacement diffusers of the QL series are deployed primarily at industrial plants.

The cool supply air is introduced into the room at low discharge velocities and very low turbulence, according to the displacement principle.

The series comprises 3 different designs. A robust variant is available for industrial applications in particular.

• These two types are notable for their flat, space-saving construction and feature an elegant face construction.
• Depending on the degree of activity of the persons in the occupied zone, the supply air can enter the space with a temperature difference of -1K to -6K in relation to the room air.

• Displacement flow
• End mounted side entry spigot for fresh air
• Heat exchanger vertically mounted with condensate drip tray for low chilled water temperatures

• TROX displacement flow diffusers type QSH/ISH are primarily used in industrial manufacturing and installed as free hanging units.
• They can be adjusted individually for any temperature range.
