Frost Fighter Indirect-Fired Heaters

Frost Fighter Indirect-Fired Heaters: Safe, Efficient Heating Solutions for Industrial Applications

When extreme cold threatens to shut down operations, Frost Fighter indirect-fired heaters deliver reliable, clean heat that keeps projects moving. These portable heating solutions have become essential equipment for construction sites, mining operations, oil and gas facilities, and warehouses across North America.

What Are Frost Fighter Indirect-Fired Heaters?

Frost Fighter indirect-fired heaters are portable heating units that provide clean, dry air by separating the combustion process from the heated air stream. Unlike direct-fired heaters that release exhaust into the workspace, these units vent combustion gases outside while delivering pure heated air through ducting systems.

This design makes them ideal for occupied spaces, confined areas, and applications where air quality is critical. The Frost Fighter offers models ranging from 170,000 BTU/h to 1.5 million BTU/h, ensuring the right heating capacity for any project size.

How Frost Fighter Indirect-Fired Heaters Work

The Indirect Heating Process

Combustion Chamber: Fuel burns in a sealed chamber, completely separated from the air being heated
Heat Exchanger: A stainless steel heat exchanger transfers heat from combustion gases to clean air
Air Distribution: Fans push heated air through ducting to target areas
Exhaust Venting: Combustion gases are vented safely outside the heated space

This process ensures 100% clean, dry heat with no fumes or moisture entering your workspace.

Key Advantages Over Direct-Fired Heaters

Clean Air: No combustion gases in heated air
Safety: Reduced fire and carbon monoxide risks
Versatility: Safe for occupied and confined spaces
Efficiency: Advanced heat exchangers maximize fuel utilization
