API Heat Transfer 

We focus our engineering expertise on the markets you serve. By understanding your customer applications, we’re able to offer a broad spectrum of components and complete engine cooling systems designed to fit the needs of engine markets across the world – whether mobile or stationary, on land or in the water, in plant or underground.

Our air cooled designs employ the latest aluminum and copper-brass technologies in an array of fin configurations to deliver the most efficient heat exchange cores in the industry. Our coolers utilize CAB and vacuum brazing, cupro braze, mechanical-bond, and soldered processes to provide the strongest materials for your application.

For liquid cooled applications, our shell and tube offering is one of the most diverse when it comes to materials of construction, flexibility in design, reliability, and efficiency. Products are available in pre-engineered or custom designs, and in a variety of materials – including metals, composites, and special alloys when needed. Plate heat exchangers are also available.
