Frost Fighter IHS1500 Indirect Fired Heater Key Features & Capabilities

Unmatched Heating Performance for Demanding Job Sites

The IHS1500 delivers serious heat—1,500,000 BTU/hr on high fire and 970,000 BTU/hr on low fire with the flexibility of dual fuel input (Propane or Natural Gas). The ball-valve switchover makes transitioning between fuel types seamless. This level of power and adaptability makes it an ideal choice for large-scale heating applications like:

• Construction & Industrial Projects
  
• Oil & Gas Facilities
  
• Utility Infrastructure Repairs
  
• Mining & Temporary Structures
  

Built with a stainless-steel heat exchanger, this unit resists corrosion and is built to last under extreme workloads.

High CFM Airflow & Industry-Leading Static Pressure

Equipped with a 5 HP motor, the IHS1500 pushes 11,000 CFM of heated air through dual  20-inch outlets, perfect for extended duct runs.

• Up to 100 ft of ducting per outlet
  
• 5″ static pressure — highest in its class
  
• Universal duct compatibility (pin lock and belt cuff)
  

This combination of power and reach ensures that heat penetrates far corners of your worksite, even in frigid, windy environments.

Engineered for Safety, Efficiency & Durability

Designed with both user safety and operational uptime in mind:

• Fully insulated outer shell — stays cool to the touch
  
• 3-Trial ignition system ensures reliable startups
  
• Independent fan and blower improve combustion control and light-off reliability
  
• Polarity light indicator confirms correct electrical hookup
  

Efficiency ratings speak for themselves:

• 81% efficiency (US standard)
  
• 91% efficiency (EU standard)
  

This results in more heat per fuel dollar and a lower carbon footprint.

Built for Harsh Environments

• Satin-coated steel + powder-coated finish for corrosion resistance
  
• Heavy-duty chassis with multiple forklift pockets and lifting hooks
  
• Compact footprint for tight work zones:
  
  • Dimensions: 156" L x 44" W x 71" H
    
  • Shipping Weight: 2,800 lbs
    

Flexible Electrical Compatibility

• 460V / 3-Phase (18.5 amps)
  
• 575V / 3-Phase (13.9 amps)
