Roof unit

Ensure optimal heating, air conditionning and ventilation in your buildings.

Benefits of a natural gas roof unit

Installed directly on the roof, this versatile unit can handle three functions: heating, air conditioning and ventilation in commercial spaces. The natural gas roof unit is ideal for effectively controlling heat and ventilation in open-air spaces. It also outperforms its more expensive and less powerful electric equivalent.

Choose performance

Provide greater comfort to occupants of your commercial spaces. With a natural gas roof unit, you can decentralize your ventilation system and control comfort levels as required.
