Heat transfer, fluid handling
and equipment servicing
for New Zealand’s
processing industries.
Specialist Thermal & Flow Solutions
Excel’s Thermal & Flow Division provides specialist solutions for heat exchangers and fluid handling equipment. From preventative maintenance and integrity testing through to refurbishment, replacement components and ongoing service support.
Working with leading international suppliers and backed by specialist testing technology, we help keep critical processing equipment performing reliably, efficiently and safely.
Keeping critical equipment performing
From routine preventative maintenance to complex equipment diagnosis, our Thermal & Flow team provides practical, specialist support throughout the life of your equipment.
We work alongside customers to identify potential issues early, improve equipment performance and reduce the risk of costly unplanned downtime.
Heat Exchanger Testing
Our specialist gas integrity testing equipment provides a highly sensitive method for identifying leaks and integrity issues within gasketed plate heat exchangers.
Testing can help identify compromised plates and gaskets, potential cross-contamination pathways and equipment integrity issues that may not be visible through conventional inspection.
We can also provide testing following servicing or repairs to verify the integrity of the heat exchanger before it returns to production.
Preventative Maintenance
A proactive maintenance programme can significantly reduce the risk of unexpected heat exchanger failure.
Our preventative maintenance services can include equipment inspection, gasket life-cycle management, scheduled testing, plate inspection, cleaning and refurbishment.
By planning maintenance around your production schedule, we help identify developing issues before they become costly production problems.
Heat Exchanger Servicing
Our specialist gas integrity testing equipment provides a highly sensitive method for identifying leaks and integrity issues with both gasketed plate, shell and tube heat exchangers.
Testing can help identify compromised plates and gaskets, potential cross-contamination pathways and equipment integrity issues that may not be visible through conventional inspection.
We can also provide testing following the servicing or repairs to verify the integrity of the heat exchanger before it returns to production.
Services can include:
- Gasket replacement and regasketing
- Plate pack inspection and refurbishment
- Ultrasonic cleaning
- Chemical cleaning
- Heat exchanger integrity testing
- Thermal imaging
- UV light leak detection
- Equipment inspection and condition assessment
- Root cause analysis and laboratory testing
Where replacement components are required, we can source quality plates, gaskets and other components through our established supply network.
Cleaning & Refurbishment
Fouling, scaling, and contamination can progressively reduce heat transfer performance and increase operating costs.
Our cleaning and refurbishment services restore peak operating efficiency without requiring complete equipment replacement.
By integrating infrared thermal imaging and acoustic emission monitoring, we can non-invasively detect internal blockages, flow maldistribution, and early-stage structural scale formation during normal operation—catching issues before catastrophic performance loss occurs.
Combined with our ultrasonic and chemical cleaning capabilities, plate inspection, and refurbishment services, we deliver a customized maintenance solution tailored to the precise condition of your equipment and process demands.
Parts & Components
Through our relationship with leading equipment manufacturers and suppliers, we provide access to a wide range of heat transfer and fluid handling components.
This includes heat exchanger plates, gaskets, replacement components and other critical spare parts.
Our channel partnership with Alfa Laval provides customers with access to genuine components and a broad range of world-leading heat transfer and fluid handling technology.
