Product Overview
When it comes to managing and improving indoor air quality, we know that you don’t want something generic. You need an air-handling solution that delivers healthy air and perfectly fits the needs of your commercial space—whether that’s a school, hospital, shopping center, or other commercial building. Enter the ENVIRO-TEC MQL Indoor Air-Handling Unit—an efficient, commercial heating and cooling system with the customizable design you’ve been looking for. Nearly everything can be changed to meet your needs: the configuration, the size, the filters, the access panels, and more. You can even customize the acoustics of this unit, an important feature in spaces where noise control is critical for building owners and occupants. With the MQL, the ability to configure the fan and coil vertically works very well for sound-sensitive areas. Now available with direct drive plenum and forward curved (FC) fan combinations, this unit offers even greater flexibility and performance.
