Isotherm, Inc. is the industry leader in providing state-of-the-art technologically advanced concepts and products in Industrial Refrigeration, with its main emphasis in Natural Refrigerants, such as Ammonia and Carbon Dioxide. We are also the first to actively use Enhanced Tubes in Ammonia system chillers, condensers and de-superheaters. The company has internal capability to fabricate such specialized tubes. It also has close collaboration with the world renowned research centers and Universities. Dr. Ayub is the founder and director of two such research centers.

We are one of the few companies in the world that fabricate both shell-tube and plate type exchangers. Dr. Zahid Ayub was the first in the United States to introduce Plate and Frame Exchangers to be used as Ammonia Chillers. The first such unit was installed at a beverage plant in North Carolina in the early 90’s.
