When designing a heat exchanger, an engineer should not only consider thermal performance, but also external influences that can negatively impact thermal performance, such as fouling.

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.

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.

We get asked a lot of questions about the passivation of stainless steel welds. Oftentimes, customers want to know what passivation is. Others ask if it’s necessary. Given the number of factors that such a decision hinges on, Super Radiator wants customers to understand the benefits of passivation, and also understand what’s involved in the larger process of treating stainless steel surfaces.
