Heat exchanger repairs, servicing, rebuilds and parts for gasketed plate, brazed plate and welded block heat exchangers, on site or in our Townsville workshop.
Eureka Water & Filtration services, rebuilds and sources parts for gasketed plate, brazed plate and welded block heat exchangers of all brands, on industrial, mining and commercial sites across North Queensland. We work on site or in our Townsville workshop, and every unit we rebuild is pressure tested before it goes back into service. Service agreements are available, and the work fits alongside our cooling tower and plant servicing.
Need plates or gaskets?
Send us a photo of your heat exchanger’s nameplate (make, model and serial number) and we will order plates and gaskets to match.
Signs your heat exchanger needs servicing
If you are seeing any of these, it is worth an inspection.
Rising pressure drop
Fouled or scaled plates restrict flow across the pack.
Falling outlet temperature
Heat transfer drops as scale and deposits build up.
External leaks
Usually worn, hardened or incompatible gaskets.
Cross-contamination
A sign of cracked or corroded plates letting one fluid into the other.
Heat exchanger repairs and services
Plate and gasket care
Tear-down and inspection
What we do
Full tear-downs, high-pressure cleaning and plate integrity inspection.
Mechanical overhauls

What we do
Frame restoration, tie-bolt replacement and correct plate-pack alignment to prevent leaks. Finished units are pressure tested before they go back into service.
Scale removal
Restore heat transfer
What we do
Chemical and mechanical descaling, then a performance check on temperatures and pressure drop. Brazed plate and welded block units are cleaned in place and pressure tested.

Heat exchanger FAQs
Which heat exchangers do you service?
Gasketed plate, brazed plate and welded block heat exchangers, from all brands. We service them on industrial, mining and commercial sites across North Queensland.
Do you work on site or in your workshop?
Both. We service heat exchangers on site where the unit can be opened in place, or bring them back to our Townsville workshop for a full rebuild.
How often should a plate heat exchanger be serviced?
It depends on the fluids and how quickly they foul the plates. Rising pressure drop or falling outlet temperature are the usual signs a clean is due. We can set a service interval from an inspection.
What causes a plate heat exchanger to leak?
Common causes are worn or incompatible gaskets, uneven tightening of the plate pack, and corroded or cracked plates. A tear-down and inspection finds which it is.
Can brazed plate heat exchangers be serviced?
Yes. Brazed plate units are sealed and cannot be opened, so they are cleaned and descaled in place and then pressure tested. If a unit fails the test, we can source a replacement.
Do you pressure test heat exchangers after a rebuild?
Yes. Every unit we rebuild is pressure tested before it goes back into service.
Can you supply plates and gaskets for my heat exchanger?
Yes. Plates and gaskets are ordered to suit your unit. Send us the make, model and serial number from the nameplate and we will order the right parts.
Do you offer heat exchanger service agreements?
Yes. We set up service agreements so your heat exchangers are inspected and cleaned on a regular schedule rather than when they fail.
How much does a heat exchanger service cost?
Each job is quoted individually. The price depends on the type and size of the unit, its condition, whether the work is on site or in our workshop, and any plates or gaskets needed.
