The VPR Series from Valent is a high-percentage outdoor air rooftop ventilator with packaged air-cooled refrigeration.
Valent units are constructed with premium features to reduce energy consumption, increase control over occupant comfort, and lengthen the product’s service life.
Panel construction: Entire casing (including access doors) comprised of 2″ foam-injected, double-wall panels for a solid structure designed for years of exposure to the elements. In addition, individual panels are thermally broken, maximizing thermal resistance and resulting in lower overall energy consumption.
Direct-drive plenum fans: Direct-drive design eliminates belts and sheaves for reduced vibration and noise transmittal. Backward-inclined plenum fans are quieter and more efficient than their forward-curved counterparts.
Evaporator and hot-gas reheat coil separation: In order to prevent condensate re-evaporation and to monitor the evaporator coil leaving air temperature, all Valent units are designed with a minimum 6″ of separation between the evaporator and hot-gas reheat coil.
Indirect gas furnace: All indirect gas furnaces include a 2-stage blower for true 4:1 turndown. In addition, heat exchanger tubes are always constructed of 409 stainless steel for years of trouble-free service.
Vertically-oriented heat wheel: Energy recovery wheels are installed vertically to minimize bearing wear. In order to simplify maintenance, energy wheel cassettes are accessible through a hinged access door and slide out of the unit without the use of tools.
