One of the world's leading breweries located in South America is paving the way for a sustainable future by investing in green technology start-ups to harness solar and wind energy for its breweries. This initiative marks the beginning of a significant transformation as the company begins to renew its energy matrix to prioritise clean sources and reduce emissions, with the firm aim of achieving carbon-zero status by 2040.

Brewing beer depends on extensive temperature and pressure control making energy efficiency and reliability critical. Our customer needed heat exchange technology that could achieve these parameters while using less water. Kelvion’s NT250 proved to be the perfect solution, providing high-performance, low-energy wort cooling.

NT250 PHE sets new standard in efficiency 
The customer wanted to replace a competitor's plate heat exchanger, which had failed to deliver the required performance at one of its sites. They were supplied with an NT250 gasketed plate heat exchanger, which impressed with its high efficiency. 

NT plate technology ideal for brewery process
Our NT range of gasketed plate heat exchangers is the perfect choice for brewing and many other industries due to its flexibility and wide range of plate lengths. With its Optiwave® design, the NT plate heat exchanger allows the flow to be evenly distributed across the entire plate surface, maximising heat transfer while minimising fouling. This makes it ideally suited to the strict hygiene requirements of the brewing industry and can reduce CIP downtime and energy intake.

Other advantages include our trademarked PosLoc® plate design, which allows plates to self-align and seal tightly every time the unit is closed, providing stress-free maintenance and reliable operation.

Energy savings of up to 25%
This unit was delivered in 2017 and is used to cool high maltose wort from 98°C to 8°C and to heat brewing water from 6°C to 90°C. 
The advanced NT plate alignment provides a critical advantage by increasing the heat transfer surface area. This results in optimum wort cooling efficiency even at higher brew water temperatures, such as 8°C, compared to 6°C in competitor units. 
“This option not only offers operational savings. It also reduces our environmental impact,” said the customer’s project manager. “By cooling the brewing water down to 8 °C instead of 6 °C, the refrigeration process is much less energy-intensive. We save up to 25% of electricity demand for brew water cooling, making this system much more environmentally friendly.”
