Demineralized Water Heat Exchangers

Sanitary Demineralized Water Exchangers:

Sales, Service & Replacement

Demineralized water is water almost completely free of dissolved minerals as a result of one of the following processes: deionization, membrane filtration (reverse osmosis (RO) or Nano filtration), electrodialysis, or distillation.

Southwest Thermal’s shell and tube heat exchangers are constructed from high quality materials with a sanitary finish, the ideal solution when cleaning is an essential part of the process. Our designs offer 100% drainable vessels with double tube sheets to guard against product cross contamination when required. The process sided connections are sanitary. We offer optional electro polishing to increase sanitary performance and minimize corrosion. 3A certification is available.

We offer demineralized water shell and tube heat exchangers from 2" to 48" shell diameters up to 65 feet in length. Multiple design styles such as multi-pass, U-tube, straight tube, and double tube sheet units are available. Our construction materials include 304L, 316L, and duplex stainless steels such as 2205, 2507, and Zeron 100. Additionally, corrosion resistant alloys like Hastelloy, Alloy 20, Monel 600, AL-6XN, Titanium and copper-nickel alloys are also available.

Tube-in-tube heat exchangers can be utilized when fluids contain significant amount of fibers or other suspended particles.  This type of exchanger is formed by two concentric tubes which are corrugated to enhance the heat transfer rate and reduce the overall size of the exchanger.  Product wetted components are manufactured from 316L stainless steel.  Duplex stainless steel materials are available for more aggressive fluids.  All areas not in contact with the product are constructed from 304 stainless steel.

We also offer brazed plate heat exchangers available in stainless steel and various alloys to meet the stringent demands of demineralized water applications. These compact exchangers offer maintenance free operation and allow for very close approach temperatures between fluids at economical pricing.

Southwest Thermal offers plate and frame exchangers to satisfy the high demands of demineralized water heat transfer. These are constructed of 304 or 316 stainless steel. Plate separation is handled by gaskets of various materials depending on your design requirements. Some of the choices in gasket materials include Nitrile (NBR), Silicone, EPDM, Viton, or Butyl.

The following is a list of typical processes that require heat exchangers of this type.  API or formulated pharmaceuticals, blood, plasma or growth media, WFI, USP, DI, RO and CIP heating /cooling, pure steam generation & condensing, bio kill & waste neutralization, and point of use cooling and/or heating.
