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.

Water Quality & Filtration in Liquid-Cooled Data Centers

Posted by Kenny Beach on Jan 12, 2021 9:13:57 AM

Cooling data center IT equipment using air has been the industry standard for as long as there's been a data center industry. However, advances in computing technology have pushed the limits of what air-cooled systems are able to efficiently keep cool, as the amount of power needed to operate those systems increases.

Uses for Spiral-Wrapped vs. Industrial Plate Fin Heat Exchangers

Posted by Super Radiator Coils on Dec 1, 2020 8:24:42 AM

In the heat transfer universe, the term ‘coil’ is typically used to describe lighter duty heat exchangers used for various HVAC-R functions across a slew of industries. However, when the pressures, temperatures, and all-around harshness of an application and installation environment are ratcheted up, this equipment commonly falls under the ‘industrial heat exchanger’ umbrella.

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.

Factors That Limit a Coil's Thermal Capacity

Posted by Brian Elliott, P.E. on Oct 27, 2020 11:48:48 AM

My parents were fond of saying, “There is only so much meat on the bone.” No matter how hungry we children were, there was a limit as to what meat we could get from gnawing a bone. The same is true for coils. No matter how hard we wish for more, a coil can only transfer a limited amount of heat. Why is that?

In What Situations Would I Even Consider Retrofitting an R-22 System for R-410A?

Posted by Al Nord on Oct 12, 2020 12:00:14 PM

Today, most new air conditioning system components that would have used R-22 prior to its regulation are now designed to operate with R-410A. However, R-22 systems, such as commercial split systems for example, still exist. This means that when a coil reaches the end of its service life, the system engineer has a decision to make: replace the system or convert the existing equipment to operate on R-410A.
