The Q-TEC Series self contained packaged water-to-air heat pump is designed to be installed inside a building structure against an exterior exposed wall when ventilation option is selected. When no ventilation option is used, the QWS Series units can be installed in any interior space accessible to water supply system and condensate drain.

Q-TEC’s design provides “whisper” quiet operation with total comfort for the occupants at high efficiency levels and eliminates the need for roof-mounted equipment and outside condensing units and can meet your specific architectural requirements.

Q-TEC’s “quiet technology” provides extremely low indoor sound levels by using special components and materials in the construction of the unit. By using special motors and sound insulation we have built a heat pump system that is significantly quieter than competitive product available today.

Q-TEC is suitable for both new construction and renovation projects for schools, modular buildings and light commercial buildings. A variety of ventilation options are designed to address your project’s indoor air quality.

The Q-TEC Series unique design allows all maintenance and service to be performed inside the building to facilitate multi-story installations. Access to air filters and controls is accomplished through a hinged front panel for easy accessibility. All Q-TEC Series models are built on heavy duty permanent rollers for easy installation and removal.
