Heat Transfer

Our partner, Armstrong International designs and manufacturers extended heat transfer (coils) equipment for air and gas treatment, including unit, tank and door heaters and more.

Heavy Duty Coils - Series 6000

A full line of coils are capable of handling virtually any service—from light-duty applications to the toughest and harshest of industrial jobs. With custom built solutions, Armstrong coils have long-lasting performance for your heating, cooling and process drying applications.

Plate Fin Coils - Duralite™

Armstrong heavy-duty industrial coils are proven in process applications with quality and dependability.

Unit and Door Heaters

Unit and door heaters are made with heavy-duty enclosures, corrosion-resistant heating cores, standard NEMA frame TEFC ball bearing motors and thick fins and tubes. These high-quality components provide the ability to maintain heat transfer efficiency and resist corrosion.

Duramix™ Face and Bypass Heating Coils

Duramix™ heating coils control air temperature while operating at full steam pressure. Once set, the desired leaving-air temperature is maintained by Duramix™, regardless of variations in the temperature of the entering air. Typical applications include HVAC air preheated systems, make-up air systems and combustion air preheat systems.

Tank Heaters

Built for industrial applications, Armstrong tank heaters feature heavy-walled pipes and headers, thick L-footed fins and oil-welded construction to handle high-pressure cleaning. Available in based-mounted or flanged-mounted types.
