SHEV systems

natural smoke and heat exhaust ventilation systems

As in case of emergency natural smoke and heat exhaust (NSHE) shall save lives, no compromises are to be made with regard to their functionality. E.M.B. Products stands for high-quality, certified SHE-systems, which guarantee their functionality even after many years of daily use. Our products are benchmarking when it comes to important requirements such as wind or snow load capacity. Thanks to their high quality our systems can also be employed for daily ventilation.

All of our NSHE systems comply with the relevant requirements according to DIN EN 12101-2 and VdS 2159.
