AIR REPLACEMENT SYSTEMS
Air replacement systems are used in buildings requiring the replacement of air having been evacuated through general ventilation or source extraction fans. We offer custom designed solutions to provide you with a top quality and long lasting solutions.
Make-up air units
These make-up air units are the most economical way that fresh air can be brought into a building to compensate for process exhaust, negative pressure or simply to complete an air change requirement. This system comprises a powerful inline fan-motor assembly, two modulating dampers and controls. The units economically reclaim heat trapped at the ceiling (roof) level and uses this free energy to preheat the incoming fresh air.
Textile air tubes
These textile air tubes are the perfect complement for make-up air units. During operation, these fabric tubes drive the air along the pipeline and diffuse it evenly in any structure that requires air (swamp cooler, air conditioning, ventilation, heating or any combination of these), unlike metal ducts which only difuse air at specific points.
