Unit ventilators with two-stage compressors

McQuay International introduces self-contained unit ventilators

06/28/2011


McQuay International’s AAF-HermanNelson self-contained unit ventilators with two-stage compressors are designed for classroom retrofits because they are a low-cost alternative to renovations, fit easily into existing ventilator space, offer classroom comfort for students and teachers, and meet energy-efficiency requirements. In addition to air conditioning with electric heat, units are available in both air source and water source heat pump configurations. The two-stage compressor reduces noise in the classroom and provides a more consistent and comfortable room temperature by allowing units to operate efficiently at reduced fan speeds a majority of the time. As a result, the units consume less energy, can assist in lowering utility costs, and require fewer repairs with longer part life. The AAF-HermanNelson self-contained unit ventilator is also one of the first console classroom unit ventilators on the market using non-ozone-depleting R-410A refrigerant.
