Nortek Global HVAC introduced the Reznor® ZQYRA Series. The company says the series is a low cost, high-efficiency dedicated outdoor air system (DOAS) for adding outdoor air requirements in educational, healthcare, office, retail, and other light commercial spaces.
The patented ZQYRA–8 (500 to 1,100 cfm) and ZQYRA–12 (900 to 1,500 cfm) units include modulating heat pumps and enthalpy wheel technology. They feature a small footprint and are ideal for adding outdoor air ventilation in smaller spaces for new and retrofit VRF or conventional DX air conditioning projects.
