Reznor 1930s Factory Video
This film was taken in the early 1930s to show the "modern" Reznor manufacturing facility.
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.
Competitive Edge: Solid Construction The Platform 125 (or P125) series got it's name because it was introduced during the 125th anniversary of the first Reznor brand unit.Like the Reznor name, these rooftop units are built to last.
Energy Edge: Condensing Gas Heating (90%+ Efficient) No matter what region you are in North America, Heating makes up the majority of the average building energy usage. By using Reznor condensing gas heating equipment (over 90% fuel efficient), you can make a big impact on the overall utility bills.
Y-Series Model Selection Based on % of Outside Air This PowerPoint slide explains why Reznor's Y-Series units (Platform 125) do not have pre-determined ranges set by the percentage of outside air the unit is bringing in.
