| |  Designers of industrial ventilation systems to reduce negative pressure and solve indoor air quality problems. Installation of KeepTheHeat™ air - air heat exchangers will reduce the need for ambient air exhausters. Facilities problems associated with welding smoke, oil mist haze, diesel fumes, carbon monoxide, humidity, and negative pressure have all been solved with custom designed industrial ventilation systems by VentilationUSA. The goals are reduction of energy wasting exhaust fans and installation of Quietaire's™ un-heated air make-up systems will be the solution; saving energy with air - air heat exchangers. | |
