A smarter way to cool and conserve
process cooling.

considering the SEPR ratings at the time of equipment selection, companies can ensure they are investing in solutions that deliver the best return on investment over time."
n industries that use cooling systems in their production processes, energy use is a major concern. Energy costs
businesses, but recent events and price spikes have brought this into sharper focus. In addition to cost, environmental concerns and the need for UK businesses to achieve Net Zero status by 2050 are also causing headaches. These cooling systems, comprising industrial chillers and refrigeration units, are crucial for ensuring product quality and safety; however, they can be energy-intensive, driving up operational costs and contributing to environmental impact. As businesses increasingly prioritise energy use and sustainability, the need for more accurate and comprehensive data to evaluate chiller performance has never been greater. One metric that provides such data is the Seasonal Energy Performance Ratio (SEPR), which is emerging as an essential measurement tool in the realm of process cooling, providing businesses with a more realistic and comprehensive understanding of energy use over time.
What is SEPR?
over an entire year. Unlike traditional metrics such as the
at a single operating point under controlled conditions, SEPR accounts for real-world variations. It assesses chiller ambient temperatures, providing a more holistic view of its actual energy consumption throughout a typical year. This is particularly important in industries where cooling demands vary seasonally, making SEPR an essential tool for accurate, long-term performance evaluation.

loads throughout the year, working harder during summer months and less during winter, which is why SEPR’s seasonal approach provides a more realistic view of their energy consumption.
This is especially relevant given the typical lifecycle of industrial chillers, which are generally replaced every 10 years. By using SEPR, businesses can make more informed decisions about their cooling systems, ensuring they choose equipment its lifecycle.
Selecting Energy-Effi cient Process Cooling Equipment
In industries such as food and beverage and pharmaceuticals, cooling systems play a crucial role in ensuring product safety and consistency. These sectors rely on precise temperature control to meet strict regulatory standards and maintain consumption and lower operational costs, their true value lies in providing more reliable and consistent cooling. This ensures that temperature-sensitive products maintain their integrity throughout the production process. For instance, in food manufacturing, precise cooling can prevent spoilage or microbial growth, ensuring that products meet safety standards without generating waste. Focusing on equipment with a higher SEPR allows companies to make smarter choices that contribute to long- term sustainability while meeting regulatory requirements. to travel further on less fuel, a higher SEPR score indicates that a chiller provides more cooling with less energy with the performance required to meet the demands of their industries, helping them reduce costs while maintaining the high standards necessary for product quality and safety.
