About Us

Flagro is a quality manufacturer of portable heaters, liquid and vapour propane torches, and liquid burners.  Our manufacturing facility is based in St. Catharines, Ontario, Canada and has been producing high quality heaters for decades.  Our line of heating products contains a wide variety of oil, propane and natural gas fired and electrical commercial portable direct and indirect heaters that range in BTUs from 85,000 BTU/hr to 1,500,000 BTU/hr.

Flagro was established in 1978, by Bruce Watson, and was acquired by Sunbelt Rentals in September of 2022.  Since the acquisition, Flagro has been able to expand our manufacturing facility and add additional products to our lineup.  Recently we have expanded our product offerings to include the Airrex product line of portable air conditioners, heat pumps, dehumidifiers, and air scrubbers/HEPA filtration units. We provide a wide range of solutions for all your portable HVAC requirements.

We pride ourselves on the quality of our products along with an unmatched dedication to customer service and technical support.  Each of our Flagro and Airrex products are tested by qualified technicians to ensure that they meet all applicable regulatory and safety standards.
