Decentralised compact air handling unit for ceiling installation

Sense is the ideal solution for both new and existing buildings. Quiet operation makes it perfect for schools, offices, and conference rooms.


Ventilation is crucial

In poorly ventilated indoor areas with a large number of people, the concentration of CO2 in the air will exceed the recommended values, negatively affecting the health and wellbeing of occupants.

Sense a healthy and comfortable environment for classroom-based learning.

Multiple studies* show fresh, clean air contributes to better concentration during learning, improves exam results, and enhances student and staff productivity.

This just makes sense!

The unit is fully exposed in the room; however, its design is adapted to be inconspicuous.

Correctly specified and positioned components are essential for the energy-efficient operation of the unit.


The frameless housing is made of painted aluminium sheet (RAL 9010), which makes the unit lighter and more compact.

Maintenance technicians can access components through the bottom of the unit using the doors on the left and right sides and a removable panel in the middle.

Counter flow heat exchanger

Aluminum or enthalpy counter flow plate heat exchanger with high heat recovery efficiency (up to 90%). Sense has a built-in motorised by-pass air damper, regulated by an integrated control system to prevent freezing of the exchanger during winter.

A condensate tray with a Φ28 mm drain connection at the back of the unit is placed under the heat exchanger.

Siphon and drain pump are available as accessories.
