ADDITIONAL INFO
Indirect Heater – 395,000 BTU Oil/Diesel – Frost Fighter IDH400QRM
The Frost Fighter IDH400QRM is a high-performance indirect-fired heater powered by oil or diesel fuel. It delivers up to 395,000 BTU/h, making it ideal for large industrial spaces, temporary structures, and demanding job sites. Moreover, it features a built-in air recirculation system, helping you save fuel without compromising heat output.
🔧 Consistent Power and Efficiency
The unit produces up to 2,800 CFM of warm air and maintains a static pressure of 2.8 inches, allowing for duct runs of over 100 feet (30+ meters). Thanks to its multi-pass stainless steel heat exchanger, it achieves a thermal efficiency greater than 81%. In addition, the fully insulated cabinet minimizes heat loss while staying cool to the touch, enhancing operational safety.
🔁 Recirculation for Fuel Savings
By recirculating the heated air back into the system, the IDH400QRM maintains more stable internal temperatures. As a result, fuel consumption is significantly reduced, especially in colder environments. This feature not only cuts operating costs but also improves overall energy performance.
🛠️ Built for the Field
The heater’s rugged frame, pneumatic tires, and lift-friendly handles make it easy to transport across challenging job site conditions. Furthermore, its quiet operation (around 62 dB) ensures minimal noise disturbance, making it suitable for sound-sensitive areas. Maintenance is simple thanks to its easy-access service panels.
