A Naturally Ventilated SHEV system ensures that smoke and heat is exhausted naturally through the natural convection of heat within the building. These systems also provide a natural supply of air.

In a fire scenario, the heat generated by the fire produces an updraft which allows smoke and heat to escape the building through the naturally ventilated SHEV system.

SHEVS (Pty)Ltd have a very unique low profiled naturally ventilated SHEV available for the market, called the SHEVILATOR™
