Direct-Fired Air Handlers for HVAC Applications

Direct-fired air handlers for the HVAC market provide heated outside air into the space. Based on building needs, air handlers can adequately maintain a pressurized space allowing up to 80% return air for reduced energy cost. All heaters are built to ETL standards per ANSI Z83.18 or Z83.4.

Four basic configuration styles are available. Heaters with a constant discharge air volume include Make-Up Air, Fixed Recirculation and Air Management. Variable Air Volume configuration sustains a variable discharge air volume ranging from 100% to 50%. Regardless of configuration selected, a minimum of 20% outside air is required. Before air is delivered into the space, it can be filtered via an inlet hood or filter section.
