The compact, yet powerful ES500 indirect fired air heater outputs 390,000 BTU/hr at up to 2500 CFM. It is diesel powered and operates for 25 hours between refuels.

At the heart of this portable heating unit is a Flagro 400 indirect fired heater powered by a Kubota engine with a Mecc Alte generator end. These main components are housed in a durable steel cabinet designed with safety and convenience in mind. The cabinet features include 200% secondary fluid containment, emergency shutdown switch, seven bright LED floodlights, and easy access to commonly serviced components. The heater is light-weight and mounted on a 3500 lb single-axle trailer for easy mobility.

The ES500 industrial heater is engineered for reliable performance in extremely low temperatures and proven on Alaska’s North Slope oil fields and in northern Canada.
