Smoke and Heat Extraction (SHE)
The secure Nauheim SHEV domes
Natural smoke and heat exhaust ventilators (SHEV) using LBO 24 volt.
24V NRA equipment is primarily used in stairwells, public meeting places and buildings subject to state building regulations. Thus standard Skylights can be installed with approved system components. The size of the dome depends upon prevailing regulatory levels, the size of the stairwell surface to be ventilated (normally 5%, but at least 1 m²).
The control of this smoke exhaust trigger is through a manual release button and an automatic alarm which triggers the electrical control unit. As an option, locking on a fire panel is possible.
Flue values for the 24-volt dome can be found on the table on page 3 of our “Skylights” brochure.
Natural smoke and heat exhaust ventilators (SHEV) in accordance with DIN-EN-12101-2
For industrial construction, we offer the DIN-EN-12101-2 certified and approved CO² dome with all its accessories.
Natural smoke and heat exhaust devices must be capable of being opened in the case of fire manually and automatically. This takes place with a thermal trigger as well as control lines to the CO2 trigger stations. This trigger system for a natural smoke and heat exhaust device can be operated with electric or pneumatic controls. As an option, locking on a fire panel is possible.
We plan, project, calculate and optimize CO2 equipment according to construction plans or requirements in adherence to current valid standards and regulations.
Flue values for the CO2 dome can be found on the table on page 3 of our “Skylights” brochure.
