Direct Fired Heat:
Direct-fired heaters are similar to barbeque grills or gas stovetops, as they heat the air that passes through an open flame.
Internal components within the heater control the warmed air, making it an efficient heating solution. This type of heating application is good for temporary applications,
for areas with limited insulation or those that need large volumes of warm air, such as construction sites or warehouses.
Direct-fired heaters use 100 percent of the combustion gases to heat air, making them more efficient than indirect-fired heaters.
Some heaters can operate in areas with temperatures as low as -30°F.
You may use ducts to carry hot air throughout a site or facility without worrying about fumes or exhaust.
This type of heater is generally less expensive to purchase or rent than indirect-fired heaters. They are also less expensive to maintain.
The heaters are made of simpler components that are easier to transport.
Small heaters produce high amounts of heat (BTUs).
Some direct-fired heaters do not need electricity to operate.
Most models have built-in thermostats.
The heaters feature redundant safety features that allow you to operate them with minimal supervision.
Direct-fired heaters are not appropriate for use in tightly sealed spaces or near flammable materials because of the exhaust and fumes produced.
The heated space must have some type of air exchange or an exterior window or door that you can open.
The warm air produced is not always dry.
You should not use direct-fired heat in spaces where materials will be affected by combustion byproducts.
When it comes to construction drying services, the manner in which you heat or dry a space matters. Using the right equipment protects construction workers and its future inhabitants,
prevents project delays and promotes a building’s health. To learn which is best for your site, get in touch with Polygon to schedule a consultation.
