Slide Out Fan
Fresh Air Hood

Model YDMA makeup air unit provides superior control of high volumes of outside air in a package DX system design. The model’s feature set allows it to properly condition 100% outside air. The unit’s blower system incorporates a superior energy efficient blower design with variable speed control to balance and control the airflow as needed. The DX system maximizes efficiency with the use of modulating digital scroll technology, ECM condenser fans and optimized coil designs. The DX system exceeds ASHRAE standard 90.1 requirements. Model YDMA can utilizes the Tcore3 condensing heat technology. Tcore3 condensing gas heating system maintains greater than 90% efficiency throughout the modulated control range. The system features state of the art stand alone control system that further maximizes energy use.
