As the UK strengthens its net-zero commitments and expands energy regulations across manufacturing, industrial operators are under increasing pressure to cut energy use and carbon emissions. For facilities reliant on process cooling, the need to improve efficiency is becoming urgent.
The UK’s legally binding net-zero by 2050 target is now shaping day-to-day operational decisions for manufacturers. Energy-intensive sectors face a combination of high energy costs, tighter reporting requirements, and growing scrutiny over Scope 1 and 2 emissions. At the same time, schemes such as ESOS (Energy Savings Opportunity Scheme) are pushing businesses to examine how efficiently their sites operate.
Process cooling is one of the largest energy loads in many manufacturing environments, yet cooling infrastructure has historically received less strategic attention than other plant systems. That is now changing as sustainable cooling technologies demonstrate clear commercial returns.
“What we are seeing across the industry is a genuine shift in how plant engineers and energy managers are approaching cooling. Historically, efficiency was a secondary consideration when specifying or maintaining a cooling plant. That has changed. Free cooling, for example, is increasingly being integrated into new and existing chiller-based process cooling systems, using ambient air temperatures to reduce or eliminate compressor operation for significant periods of the year.
Similarly, heat recovery is moving from a best-practice recommendation to an operational priority. We recently completed a heat recovery project where waste heat from the cooling process is being recaptured and redistributed for use elsewhere in the facility, rather than simply being rejected into the atmosphere. These approaches represent a meaningful step-change in how manufacturing sites can reduce both their energy spend and their carbon footprint, independent of what fuel source they are running on.” Owen Crawford, Sales & Project Director, Direct Cooling Solutions.
Alongside the financial case, regulations are tightening. The Environment Act 2021 and evolving F-Gas regulations are forcing manufacturers to review cooling system specifications and plan for the phased reduction of high global warming potential refrigerants. Many businesses are using this as an opportunity to replace ageing equipment with more efficient systems.
Energy audits are also uncovering widespread inefficiencies, including oversized cooling systems, poor part-load performance, lack of variable speed drives, and inefficient sequencing of multiple units. In many cases, significant energy savings can be achieved through optimisation rather than full system replacement.
“The manufacturing sector has historically under-invested in cooling infrastructure relative to the role it plays in energy consumption and production continuity. With energy costs unlikely to return to pre-2021 levels and regulatory obligations only increasing, we would expect to see a sustained increase in capital expenditure on cooling efficiency over the next three to five years.
The businesses that move early will be better positioned competitively, not just in terms of operating costs but in their ability to meet the sustainability reporting requirements that are increasingly being demanded by customers and supply chain partners.” Crawford added.
For smaller and mid-sized manufacturers, the challenge is often accessing the right technical expertise. Assessing free cooling integration, heat recovery opportunities, and refrigerant transition planning requires specialist engineering and compliance knowledge. Government support, including the Industrial Energy Transformation Fund (IETF), can help eligible businesses invest in energy-efficient plant, though uptake remains uneven.
Direct Cooling Solutions says manufacturers should now treat cooling infrastructure as a strategic asset rather than a fixed overhead. With energy costs high and sustainability expectations rising, businesses that act early are likely to gain both operational and competitive advantages.
