Immersion Heater Role and Types for Water Purification, Part 2

September 8, 2020
by Gordo Sales Team

In part one of this two-part blog series, we went over some of the basics on immersion heaters and the role they often play in the water purification process. Many facility applications require clean and potable water, such as medical and chemical industries, and immersion heaters are often in place to assist with this and related themes.

At Gordo Sales, we’re happy to offer a wide range of immersion heaters for this and other purposes, from flanged immersion heaters to screw plug heaters, over-the-side heaters and more. In today’s part two of our series, we’ll start digging into these specific immersion heater varieties in terms of their use for water purification needs, plus give you some notes on the value of custom designs for these products.

Flanged Heaters

Electric flanged heaters are one of the most common immersion heaters out there, and they’re particularly useful for water purification (among other purposes). They involve the heater being bolted to a matching flange, which is welded to the tank or nozzle being used. One of the main reasons they’re so popular here: With custom element configurations that are easily possible, virtually any tank size corresponds to use of a flanged heater.

For this reason, flanged heaters are often used in water-based applications. Their sheath materials make their use in corrosive environments valuable, typically including either hairpin or bugle tubular elements for their configuration. They are generally the top choice for larger tanks.

Screw Plug Heaters

In many ways, screw plug heaters are similar to flange heaters. Their configuration will often be the exact same, in fact, and they also fit on many different tank sizes if they have the proper customization, though they are somewhat limited here once tank size goes above a certain threshold (our pros can detail this threshold for you).

The main area where they differ, however: Their installation. Unlike flanged heaters, which are welded onto their tanks, screw plug heaters – as the name suggests – are actually screwed in. This makes them extremely efficient and versatile compared to flanged heaters, which often makes up for the fact that they aren’t ideal for larger tanks. For any small or medium tanks, screw plug heaters are usually the ideal choice for water purification.

Custom Designs

As we’ve noted in a couple places here and during part one, customization is a huge part of the value of these immersion heaters within the water purification realm. Designs must be able to match the specifications of a given operation, tank, distribution loop and other factors. Flanged heaters are a great example of the value of customization: With it, they can service virtually any tank size; without it, they’re far more limited.
