I'm sick of replacing corroded coils. Should I consider all stainless?

Posted by Louis Rogerson on Jun 8, 2020 11:33:29 AM

Oftentimes, using stainless steel components seems like a simple solution to corrosion on coils. You may see fins or tubes or other parts of the system show signs of corrosion, and it seems that the best option is to change the coil to stainless steel, solving the corrosion problem permanently. While this seems like a simple solution to a significant problem in the HVAC, industrial, and commercial systems where coils are found, the answer to the question “should I make an all-stainless coil?” is far more complex.

Fin enhancements for plate fin heat exchangers: purposes and tradeoffs

Posted by Super Radiator Coils on Jun 8, 2020 11:11:15 AM

In plate fin heat exchangers, the fins themselves play a critical role. They provide the extended surface area needed to achieve effective heat transfer between a gas on the finside and a fluid on the tubeside.

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.)

Surface treatment of stainless steel: pickling, descaling, passivation

Posted by Super Radiator Coils on Apr 22, 2020 3:49:44 PM

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.
