To accomplish this goal, Unison blends the latest technology with a customer-centered approach to provide your company the best products and support. 

Since its foundation in 2006, our company has grown from a small team to a leading manufacturer and supplier of process solutions. We manufacture and supply state-of the-art machinery and systems specialising in pasteurisers, homogenisers, separators, heat exchangers, pumps and valves. Unison is also revolutionising heat exchanger testing with our groundbreaking Heat Exchanger Integrity Self-Testing (HEIST™) system - the world’s first fully automatic system for testing heat exchangers. 


To provide innovative and effective process engineering solutions. Our focus is to elevate the business of our clients by delivering unrivalled innovation, efficiency and value. 


We aspire to be a leading international process engineering organisation renowned for our innovative systems and equipment.


This is where Unison Process Solutions comes in. As a leading manufacturer and supplier of process solutions, At Unison, we specialise in liquid processing. We manufacture and supply state-of the-art machinery and systems specialising in pasteurizers, homogenizers, separators, heat exchangers, pumps, and valves. We are also revolutionizing the way that heat exchangers are tested with our HEIST™ system, the world’s first integrated Heat Exchanger Integrity Self Testing system.

Whether you are a small or mid-sized company, a multinational corporation, a farmer or an artisan producer – we can help you improve your process.

One of our core products at Unison is our pasteurizers.

Why the focus on pasteurization? Over the past few years, consumers have enjoyed the benefits of improved food safety and longer shelf lives as a result of the increased emphasis on pasteurization. This means more and more producers are searching for a cost-effective solution. 

Having spoken with our clients to find out exactly what they need, our engineering and design team has developed Unison’s unique range of innovative compact and bespoke pasteurizers. A key strength of Unison’s pasteurizers is that they meet the needs of the small to medium-sized producers who traditionally had two choices: invest in larger equipment than required or settle for laborious and time-consuming batch pasteurizers.

User-friendly and fully automatic, Unison’s pasteurization systems are uniquely built and designed to accommodate artisan producers’ exact specifications. Catering for all liquids including Milk, Beer, and Juice, and processing 200 to 50,000 litres of liquid per hour – our continuous systems save time, energy and money. It's truly a win-win for producers. 

Studies on milk production have shown that batch and flash pasteurization results in the exact same quality milk, in fact, flash pasteurised milk tastes better. Our flash pasteurizers use one-tenth of the energy and are proven to be three times faster than batch pasteurisers in processing milk, enabling our clients to save thousands a year.


At Unison, we also specialise in non-destructive heat exchanger integrity and holding time testing. These solutions allow companies to test their key heat exchangers quickly and effectively, with cutting-edge technology that reduces the risk of product contamination and costly recalls.

Our patented HEIST™ and Pastest+™ systems are the most advanced integrity testing methods on the market. HEIST™, the world’s first integrated Heat Exchanger Integrity Self Testing System, means that you are now able to integrity test your Plate Heat Exchangers daily, 365 times a year, rather than the typical 2-4 times annually. By testing before starting production, HEIST™ greatly reduces the risk of contamination that can occur in between tests along with putting an end to the need to open-up the system on site.

Ultimately, our HEIST™ system empowers companies to manage their heat exchanger testing so they can reduce safety risks before diving into production. Unison’s solution translates to time and money saved, from completely eliminating the risk of expensive recalls and reducing costs on service repairs, to wasted production and labour.

Unison’s unique technology is revolutionising the way companies test their pasteurisers and plate heat exchangers by providing innovative, cost-effective solutions to everyday problems.
