TIG welding in manufacturing: advantages and tradeoffs

Posted by Ben Smith, CWI on Nov 11, 2020 9:36:34 AM

Gas-tungsten arc welding (GTAW), or more commonly, Tungsten Inert Gas welding (TIG), is a method of arc welding named for the non-consumable tungsten electrode used during the process. TIG welding isn’t the best option in some industries, but as coil manufacturers, it makes sense for us.

Other than copper and aluminum, what materials are used to build heat exchangers?

Posted by Super Radiator Coils on Sep 8, 2020 8:27:34 AM

In many of the industries we serve, heat exchangers made with copper tubes and aluminum fin are extremely popular, and very often, these materials are a terrific choice. But copper and aluminum aren’t suited for everything. At Super Radiator Coils, the needs of many of our customers often dictate that we explore and understand alternative materials.

Airside fouling in heat exchangers: causes and solutions

Posted by Louis Rogerson on Jul 13, 2020 6:02:25 PM

Fin tube heat exchangers are subject to fouling, which takes place as long as there is an airflow or waterflow in the unit. Defined as thermal resistance due to the accumulation of contaminants on heat transfer surfaces, fouling negatively affects heat exchanger efficiency, longevity, and increases system operating costs.

Frost frustration: studying fouling in gas turbine inlet filter houses

Posted by Louis Rogerson on Jun 8, 2020 10:57:32 AM

An 800MW 2x1 combined-cycle power plant in Alberta, Canada was experiencing consistent frost issues on anti-icing coils in their gas turbine inlet filter houses. The purpose behind these coils is to bring the temperature of the air up to just above the dew point, to prevent the condensation of water (which can cause serious damage through icing if introduced into the turbine.)
