The MAC 2.5ES is a relatively large platform, but slightly smaller than our MAC 4.2ES. The MAC 2.5ES delivers 2,500,000 BTU’s per hour (733 kW/hr) of heat. It is an indirect diesel fired heater that provides clean, safe, and reliable air flow capable of ducting long distances with minimal loss of air pressure or outlet temperature to the targeted area. The MAC 2.5ES is comprised of rugged, heavy-duty steel construction inside and out. Large doors provide easy access for service, maintenance, and operation.

The MAC 2.5ES has a temperature rise of up to 180 degrees Fahrenheit (82 degrees Celsius) and an air output volume of 12,000 cubic feet per minute at 3 inches of static pressure, delivered through a single 30 inch outlet. The heat exchanger is MAC designed and constructed of stainless steel. We offer simple to use, push button controls for ease of operation. Manufactured in North Dakota, U.S.A.
