Direct-fired air heaters offer economic heating safely for residences, warehouse and other structures. This type of heating system can keep the occupants warm in large and smaller structures. It depends upon the type. In fact, there are two basic applications of the technology: Space heating and make up air units. Of the two, direct fired make up air heaters, or direct-fired MUA units provide diverse advantages when it comes to outdoor and/or large structure applications.
What Is an Indirect Fired Air Heater?
Direct-fired heating is a system which features a fan and a burner. Modern units are self-contained. The fan draws the air into the heating unit. The air moves across the burner and the fan then pushes it out as heated air into the duct run or directly into the structure. A space heater utilizes this technology to provide air to a specific space.
What Is an Indirect Fired Make Up Air Heater?
The principle for direct fired make up heaters is the same. The term “make-up” indicates the air in use is to make up for the lack of fresh air within the interior. The lack of air within the space or the inadvisability of using the air currently in the room or space means the air must be sourced from outside the space. Any space where the air cannot be either used or recirculated is another reason for employing an indirect fired MUA system. No matter why the facility requires such measures, the heaters ensure the space retains warmth without negatively affecting the required air quality.
Applications of an Indirect Fired Make Up Air Heater
Direct-fired MUA units commonly find use in various facilities where the exhaust or ventilation load is huge. This is more common in larger buildings or spaces. Industrial applications include:
- Aircraft service facilities
- Automotive service facilities
- Construction sites
- Food processing plants
- Foundries
- Manufacturing paint booths
- Warehouses
All are common places where employees and sites are kept comfortable through the application of direct-fired technology. The heaters are also effective at making sure the workplace maintains comfortable levels of moisture or humidity.
Direct Fired Make Up Air Heaters
Direct-fired technology provides companies with an energy-efficient, safe and very cost-effective means of heating. Applications vary according to the type of direct fired heater. A space heater, for example, is restricted in its capabilities to produce heat for a large expanse. On the other hand, direct fired make up air heaters prove to be very efficient and effective in addressing the heating needs of very large spaces.
