When your project is exposed to harsh weather, keeping your team warm and your materials at the right temperature is non-negotiable. For construction managers, event planners, and industrial operators, reliable job site heating solutions are crucial. This is where Flagro portable heaters excel, offering durable and efficient temporary heat for the most challenging environments.
Let's look at what makes Flagro heaters tough enough for your site.
Heavy-Duty Construction From the Ground Up
Flagro heaters start with robust materials designed to absorb impacts and resist wear.
Welded Steel Frames
16-gauge welded steel forms the backbone of every Flagro heater. Reinforced corners and impact zones protect critical components from drops, vibrations, and rough handling during transport.
Stainless Steel Heat Exchangers
Heat exchangers use 304-grade stainless steel for corrosion resistance and long-term thermal efficiency. Impact panels add another layer of protection in high-traffic environments.
Weather-Resistant Finishes
Powder-coated and e-coated chassis prevent rust and wear. UV-stable plastics resist sun damage, while cold-tolerant materials maintain flexibility in freezing temperatures.
Mobility Solutions for Fast Deployment
Getting heat where you need it quickly matters. Flagro heaters include multiple features to simplify transport and setup.
-
Flat-Free Wheels: High-density, puncture-proof wheels roll smoothly over rough terrain without maintenance
-
Forklift Pockets: Built-in lifting points allow fast loading and unloading with standard equipment
-
Stackable Frames: Compact designs nest together for efficient storage and transport
-
Grab Handles: Strategically placed handles make manual positioning easier
Performance in Extreme Conditions
Cold weather and remote locations create unique operational challenges. Flagro addresses these with specialized technology.
Riello Burner Technology
Advanced Riello burners include nozzle pre-heaters and low-temperature fuel pumps to ensure reliable ignition in freezing conditions. These systems maintain consistent performance even when ambient temperatures drop below zero.
Recirculation Hood Systems
Recirculation hoods boost efficiency by cycling warm air back through the unit. This technology delivers faster heat distribution while reducing fuel consumption—critical for sites with limited fuel access.
Tiger Loop Fuel Filtration
The Tiger Loop system eliminates air locks in fuel lines, preventing interruptions caused by contaminated or inconsistent fuel supplies common on remote job sites.
Safety Features That Protect Operations
Flagro heaters include multiple safety interlocks and monitoring systems to prevent accidents and equipment damage.
- High limit and fan limit switches prevent overheating
- Low oxygen and flame failure sensors trigger automatic shutdowns
- Fuel leak detection stops operation before hazards develop
- Protective outlet grilles and duct shields prevent contact burns
- Emergency shutoff switches provide immediate manual control
All models meet UL and CSA certifications, including UL733, ANSI Z83.7/CSA 2.14, and ULC standards.
