Direct-fired make-up air heaters work well in most types of construction applications, helping to control moisture and air contaminants. These heaters operate like a permanent air handler, providing evenly distributed, warm, dry air. Installed either inside or outside, E5MA Series heaters draw 100% fresh air through the units intake and discharge tempered air controlled by a remote thermostat.
Features:
• Electronic modulating burner controls and remote space thermostats automatically adjust gas flow, saving money on fuel costs

What Is Make-Up Air?
Make-up air is air from the outdoors that is heated and then evenly distributed indoors in a controlled manner to replace air that is being exhausted. This drier, tempered, fresh air has the ability to absorb the moisture and ventilate the fumes from the construction process. It provides lower relative humidity levels and dew point temperatures inside the building to prevent condensation and minimize the potential for mold.
Why Use Make-Up Air?
All buildings infiltrate, or “breathe.” This naturally occurring air movement happens when there is a temperature difference between the inside and the outside. Because buildings breathe, and because there are air contaminants (paint, adhesives, exhaust gases, etc.) and moisture during construction that need to be diluted/exhausted, it is desirable to mechanically control the process through the heater. E5 Energy’s make-up air heaters allow the introduction of controlled amounts of fresh, tempered air from the outside. A recirculating heater only attempts to control the temperature issue. It adds moisture from the combustion process, and relies on uncontrolled infiltration to ventilate.
Make-Up Air Heaters Provide:
• Controlled mechanical ventilation
• Lower dew point temperatures
• Reduced hot and cold spots
• More uniform interior and surface temperatures
Ordinary Recirculating Heaters:
• Intensify uncontrolled infiltration
• Recycle stale, dirty air
• Increase hot and cold spots
• Increase moisture and contaminant levels
