Industrial repair and liquid ring vacuum pump solutions to the power industry
Rezitech has supported Australia’s power industry for more than 50 years, providing engineered repair, protection and maintenance solutions for critical power generation equipment and infrastructure.
Our experience spans conventional power generation, hydroelectric facilities, renewable energy assets and power distribution networks, helping operators extend equipment life, reduce downtime and avoid unnecessary replacement.
Across power generation facilities, Rezitech solutions are used to repair and protect pumps, turbines, condensers, valves, pipework, tanks, structural assets and other equipment affected by corrosion, erosion, cavitation, abrasion and general wear. Our cold-applied repair composites, protective coatings and composite reinforcement systems provide practical options for restoring damaged assets while helping minimise disruption to operations.
Rezitech also supports the wider electricity network with solutions for transformer oil leaks, SF₆ gas leaks, corrosion protection and maintenance of electrical infrastructure. From hydroelectric generation to wind farms, substations and transmission assets, our team provides technical support, product supply and application services across Australia.

Rebuild and Repair
Restore worn, corroded or damaged power industry equipment and components to extend service life and reduce the need for replacement.
Restore worn, corroded or damaged power industry equipment and components to extend service life, improve reliability and reduce the need for costly replacement.
Rezitech provides cold-applied repair solutions for pumps, shafts, valves, flanges, pipework, tanks, turbine components, bearing housings and other critical plant affected by corrosion, erosion, cavitation, impact or general wear.
These repair systems can be used to rebuild lost metal, restore profiles and tolerances, seal damaged areas and reinforce weakened components—often without the need for welding or hot work. This can help reduce shutdown time, simplify maintenance and return valuable equipment to service more quickly.

Protective Coatings
Protect critical plant and infrastructure from corrosion, erosion, cavitation, abrasion and chemical attack.
Protect critical plant and infrastructure from corrosion, erosion, cavitation, abrasion and chemical attack with high-performance protective coating systems designed for demanding power industry environments.
Protect critical plant and infrastructure from corrosion, erosion, cavitation, abrasion and chemical attack with high-performance protective coating systems designed for demanding power industry environments.
Rezitech supplies and applies Belzona protective coatings for pumps, valves, condensers, tanks, pipework, turbine components, structural steel and other assets exposed to aggressive operating conditions. These cold-applied polymeric systems can be used to create durable barriers against corrosion and chemical attack, while selected Belzona systems also provide resistance to erosion, cavitation and abrasive wear.
Where conventional abrasive blasting is difficult, costly or impractical, NanoPrep provides an alternative surface preparation and corrosion-protection solution for steelwork. NanoPrep can help treat and stabilise corroded surfaces prior to overcoating, reducing the need for extensive blasting and containment. This can be particularly useful on tanks, structural steel, substations and other large or difficult-to-access assets where minimising downtime and surface preparation requirements is important.

Pump and Valve Repairs
Repair and rebuild pumps and valves affected by corrosion, erosion, cavitation and wear to restore performance, extend service life and reduce the need for replacement.
Restore worn, corroded and damaged pumps and valves with engineered repair and protection systems designed for demanding power industry applications.
Rezitech provides repair and refurbishment solutions for pumps and valves affected by corrosion, erosion, cavitation, abrasion and general wear. These systems can be used to restore damaged surfaces, rebuild lost metal, repair worn sealing and mating areas, and return critical components to a serviceable condition.
Belzona cold-applied repair composites can be used to rebuild pump casings, impellers, valve bodies, flanges and other worn components without the need for welding or hot work. Where required, high-performance protective coatings can then be applied to provide additional resistance to corrosion, erosion and cavitation, helping extend equipment life and improve long-term reliability.
By restoring existing pumps and valves rather than replacing them, Rezitech can help power generators reduce replacement costs, shorten maintenance time and return critical equipment to service more quickly.

Substation Repair Solutions
Repair and protect transformers, switchgear, structures and other substation assets affected by corrosion, leakage and general deterioration.
Repair and protect transformers, switchgear, structural steel and other substation assets affected by corrosion, leakage, weathering and general deterioration.
Rezitech provides cold-applied repair and protective solutions that can help extend asset life, reduce maintenance requirements and avoid premature replacement of critical infrastructure. Applications include transformer oil leak repairs, corroded transformer tanks and cooling fins, flange and joint sealing, switchgear enclosures, structural steelwork, concrete plinths, bunded areas and other exposed substation infrastructure. Belzona repair composites and protective coatings can be used to rebuild damaged metal, seal leaks and provide long-term corrosion protection, while NanoPrep can offer an alternative surface preparation solution where abrasive blasting is difficult or impractical.
Because many substation repairs must be completed with minimal disruption, cold-applied systems can be particularly valuable where welding, hot work or major equipment removal would be undesirable. Rezitech can provide technical support, product selection and application services to suit the condition of the asset and the operating environment.

SF₆ Leak repairs
Seal SF₆ gas leaks from flanges, joints and electrical equipment using cold-applied repair systems designed to minimise leakage and support continued operation.
Seal SF₆ gas leaks from flanges, joints and electrical equipment using cold-applied repair systems designed to minimise emissions, reduce gas loss and support continued operation of critical power infrastructure.
Rezitech provides repair solutions for SF₆-insulated switchgear, transformers, bushings, flange connections and associated electrical equipment where leakage is occurring around bolted joints, seals or deteriorated interfaces. Belzona cold-applied systems can be used to encapsulate and seal leaking areas externally, helping avoid welding, hot work or major component replacement.
These systems can be particularly useful where equipment access is limited or where shutdown time needs to be minimised. Rezitech can assist with assessing the leak location, selecting a suitable repair system and carrying out the application to provide a durable external seal and help reduce ongoing SF₆ loss.
