Coils' Roles in Football's Biggest Game

Posted by Super Radiator Coils on Feb 4, 2021 7:02:31 AM

As far as stages go, the big game is one of the biggest out there, and there’s a small army responsible for making sure the game goes off without a hitch. Behind that army of personnel is an even larger assemblage of vehicles, equipment, and other technology that help along the way – one of which is the heat exchanger.

Material & Designs Used for Low-Temp Heat Exchangers

Posted by Chris Strickler on Jan 25, 2021 11:19:35 AM

There are a number of industrial processes that require extremely cold temperatures – sometimes as cold as -150°F. For the equipment used in such applications, those low temperatures pose some unique challenges. In this post, we’ll detail some of the temperatures involved and outline some things to consider with regard to heat exchanger design and materials for low-temp applications.

3 Advantages of TIG Welding in Manufacturing

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.

Ethylene Glycol vs. Propylene Glycol: Differences & Uses

Posted by Will Klick, P.E. on Sep 28, 2020 3:35:57 PM

For low-temperature hydronic systems, systems in which chillers and AHUs are located outdoors, or other equipment used in low-temperature processes, some form of glycol is a critical ingredient. It works to lower the fluid’s freezing temperature, enabling lower-temperature operation and preventing freezing.

Features of Evaporators Used for Vegetable Cold Storage

Posted by Super Radiator Coils on Sep 9, 2020 11:35:08 AM

This article has been updated. It is accurate as of 9/23/20.

Heat exchangers used for different applications need different design features. For example, in industries like pulp and paper, lower fins per inch (FPI) are often included to reduce airside fouling and to make for easier cleaning. Other applications such as the military are often concerned with weight, which impacts material selection. For this post, we're going to focus on some unique design choices we often include when building heat exchangers for the refrigerated storage of potatoes, onions, beets and other vegetables.

Transcritical CO2 Refrigeration: Basics and Benefits

Posted by Ken Allen on Jun 23, 2020 12:18:42 PM

Around 2010, the first refrigeration systems operating on transcritical CO2 began cropping up in North American supermarkets. Since then, usage of transcritical CO2 systems has grown steadily and they’ve become viable options for places like supermarkets, food warehouses, and ice rinks, as more organizations move away from traditional HFC refrigerants. Natural refrigerant market accelerator Shecco estimates that transcritical CO2 systems grew from 140 in 2008 (all in Europe) to more than 35,000 systems worldwide today.

Benefits & Tradeoffs of All-Stainless Steel Coils

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.

Evaluating Types of Fin Enhancements for Plate Fin Heat Exchangers

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.

How to Choose the Appropriate Corrosion Resistant Coil Components

Posted by Ken Allen on Jun 8, 2020 10:41:09 AM

This article has been updated. It is accurate as of 9/23/20.

For commercial operations that rely on effective heat transfer, external corrosion of heat exchanger components is a major concern. When left unchecked, corrosion can significantly reduce a coil's effectiveness, but sometimes it’s difficult to know which anti-corrosion option best meets your needs.
