Direct Fired systems are very efficient and safe for space heating applications. Very well suited for the following:
When you need a heating solution for large volumes of ventilation air, then direct fired units may be the right solution offering:
Not recomended for schools or high occupancy areas due to the normal aldehyde smells that result from natural gas combustion.
DF direct fired air handling units combine high efficiency heating and ventilation across a broad spectrum of industrial and commercial applications. Combined heating and ventilation units ensure precise control, excellent indoor air quality and optimum energy efficiency. There are units with a constant flow of fresh air, with a variable flow of fresh air and with variable return air.
