MAC, Inc. manufactures the Chinook line of indirect-fired portable air heaters. These industrial and commercial heaters are made to withstand the harshest of cold weather climates imaginable while providing a heat source for equipment and personnel.
Each of our Chinook heaters are test run before leaving our yard. We have found North Dakota Winters have proved to be an excellent climate for our testing grounds and prototype trials - easily operating in the sometimes -50 degree temps! Chinooks thrive in the extremes!
