Based upon years of data from live test sites, SE Evello is an innovative system solution designed to ease the effects of heat accumulation whilst creating a more comfortable environment in communal spaces and corridors. Designed to utilise and integrate with a building’s existing smoke ventilation system, the system constantly monitors internal air temperatures on every floor and manages ventilation demand via the smoke extract system. The overheated air can be vented to the atmosphere and replaced by cooler outside air, which reduces the internal temperature.
