Ajax Boilers

Ajax Boiler, Inc. designs and manufactures a comprehensive line of boiler and commercial water heating products. With over eight decades of experience, the company offers high quality, heavy duty products with a reputation for reliability, serviceability, and cost effective operation.

Ajax boilers perform dependably and quietly, providing commercial, institutional, and industrial buildings with space heating, domestic, and process hot water.  Inclined tubes provide uniform heat transfer, resulting in high fuel economy and long boiler life.  2" O.D. tubes (steel or copper) are rolled into large headers on both ends producing excellent boiler circulation.  Also, Ajax's straight tube design allows for easy inspection of tube conditions.
