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.

4 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.

Flexible Scheduling and Reliable Delivery for OEMs

Posted by Super Radiator Coils on Jun 17, 2020 2:22:25 PM

We serve a diverse customer base at Super Radiator, one segment of which are what’s known as original equipment manufacturers (OEMs). Though we classify them together, OEMs and their respective industries all operate differently. Some customers are recurring business – they need coils every week consistently over a given timeframe – we’ve seen this with commercial HVAC or datacenter OEMs. Other customers need us to supply coils for projects that may arise infrequently over a period of years, which describes industries like transit cooling.

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.

Differences Between Plate & Spiral Fin Heat Exchangers

Posted by Super Radiator Coils on Jun 8, 2020 10:20:58 AM

It was long thought that a spiral fin design was the only option for use in environments that demanded heavy materials, long life span, and overall sturdiness. Plate fin coils were thought to be too fragile for the rigors of many industrial applications. But over the last few decades, it's become more common to see plate fin style heat exchangers used for a bevy in industrial applications.
