ADDITIONAL INFO

Indirect Heater – 395,000 BTU Propane/Natural Gas – Frost Fighter IDH400QRM LP/NG

The Frost Fighter IDH400QRM LP/NG is a high-performance indirect-fired heater designed to run on propane or natural gas. With an impressive output of 395,000 BTU/h, it provides reliable, clean heat for demanding applications such as construction sites, industrial facilities, or temporary structures.

🔧 Reliable Power and Efficiency

This unit delivers up to 2,800 CFM of hot air with a static pressure of 2.8 inches. It can easily supply heat through ducts over 100 feet (30 meters). Additionally, its multi-pass stainless steel heat exchanger ensures a thermal efficiency above 81%. The fully insulated cabinet reduces heat loss and stays cool to the touch, even during extended operation.

🔁 Fast and Flexible Fuel Switching

Thanks to its Ball Valve Switchover system, switching between propane and natural gas is quick and simple. This flexibility allows the unit to adapt easily to your site’s fuel availability. Furthermore, the standard air return feature recirculates warm air into the system. This reduces fuel consumption while maintaining consistent indoor temperatures.

🛠️ Durable, Mobile, and Quiet

The heater’s rugged frame includes forklift pockets, lifting handles, and heavy-duty 6-ply pneumatic tires, making it easy to move on uneven terrain. It also operates at just 62 dB, making it suitable for noise-sensitive environments.
