The Reznor ZQYRA Series is a low cost, high efficiency dedicated outdoor air system (DOAS) for adding outdoor air requirements in light commercial spaces.
The ZQYRA–8 (500 to 1,100-CFM) and ZQYRA–12 (900 to 1,500-CFM) units combine control design with modulating heat pump, enthalpy wheel technology and a small footprint.
Its Selection Software expedites specification easily because inputs require only basic project parameter data.
The Series features: supplemental electric heat control that uses an SCR time-proportioned modulation controller; extended heat pump operational time during low ambient temperatures; and a refrigerant charge compensator.
