After the installation, D+H makes sure that the installed smoke vent operates flawlessly.

​A client asked us to design a smoke and heat extraction system according to the standard (longitudinal ventilation in the car park).

These workshops were designed in order to fulfill the current requirements as regards pollution, thanks to a system of smoke clearing and recycling.

The smoke-suppression system upgrades were put on hold, to accommodate the 192 immigration detainees transferred from the Toronto West Detention Center.

In the event of a building fire, you need to provide smoke extraction in the roof area and supply fresh air at the lower section of the wall.

The study has thus prevented the construction of a completely new smoke extraction system, while ensuring a safety level equivalent to that required by the regulations in force today

This European Standard specifies requirements and gives test methods for natural smoke and heat exhaust ventilators which are intended to be installed as a component of a natural smoke and heat exhaust system.

The smoke-suppression system upgrades were put on hold, to accommodate the 192 Federal detainees transferred from the Toronto West Detention Center.

The sample board (circa 1972) is the first complete smoke vent system from D+H. The letters EHP stand for Electric-Pneumatic-Hydraulic and were a product brand and previously part of the company's name.

The whole building is protected by sprinklers, and new galleries have a smoke control system for areas incorporated into the walls of thick glass to remove the smoke on the basis of a signal fire fans.
