Regasketing Heat Exchangers

Reconditioning plate heat exchangers is a method of renewing the efficiency and like of a plate heat exchanger. We offer the most comprehensive reconditioning service to the process, HVAC and light industries. Under our "All Brand Service" we recondition and regasket all manufacturer's brands of plate heat exchangers including Alfa Laval (Vicarb) and Tranter, APV, Armstrong, ITT, Sondex, Swep, Polaris, GEA and Schmidt.

Our process involves careful steps to ensure the plates metal characteristics are not compromised during this procedure.
Our unique and innovative method of removing gaskets in a nitrogen tank whereby the gasket is frozen from its groove extends the life of the plate.

We service the following brand name heat exchangers:

Vicarb
Tranter
APV
Armstrong
ITT
Sondex
Swep
Polaris
GEA
Schmidt

Other Services
To support our heat exchangers we also offer a wide range of maintenance and technical services to keep your equipment performing at its optimal best. As users of heat exchangers you may already enjoy impressive heat transfer rates, but are always on the look out for any way to maintain your equipment and keep it free of worn out parts, i.e., gaskets, dirt, contamination and corrosion.

Since nothing lasts forever, even the best designed equipment is going to eventually deteriorate to a point where productivity suffers and your profits shrink. Valutech's reconditioning and maintenance service for plate heat exchangers comes with a “as-good-as-new guarantee" and can only enhance your bottom line.

Gasket Removal	Plate Cleaning
The plates are immersed in a liquid nitrogen bath at -196° C (-320° F). After one minute at this temperature, the gaskets become brittle, shrink, and separate cleanly from the plate	The deposits to be removed from the plate naturally vary in composition. Most types can be removed by immersion in a series of chemical baths. If required, we also use other methods for cleaning.

Inspection	High Pressure Cleaning
Use in excessively corrosive applications may cause minute pinholes or cracks not visible to the eye. To find these flaws, the plate is sprayed with a dye penetrant and is then inspected under ultraviolet light or with a developer.	The plate is then cleaned by high pressure water jet to remove all traces of the dye penetrant.

Regasketing	Oven Curing
Date stamped gaskets are selected from stock and bonded to the plate with a two component epoxy resin adhesive.	The glue is oven cured to form an immensely strong bond to the plate. This oven cured epoxy is far superior to a rubber-based cement.

Pressure Testing	Installation
The plates are pressure tested before they are shipped back to their owner.	Valutech can provide installation and start-up services if required.
