Direct-Fired Heating & Ventilating

R-Series offers the Best Available Technology for environmental friendliness, energy efficiency, and indoor air quality (IAQ) in make-up air and heating and ventilating applications. These systems deliver “total air management” by introducing a slightly positive pressure to reduce heat stratification and limit infiltration of cold air, dust and dirt.


With “green engineering” a mandate, innovative R-Series is an excellent choice. R300 models offer low first-cost, while R400 models set a new standard for premium construction. Both offer a wide range of facility air-management choices, as well as maximum installation flexibility. The line is ETL-certified to ANSI design standards and offers many options.
