Keeping Your Workforce Cool: Summer Climate Control for Manufacturing Facilities

Manufacturing environments are among the most challenging spaces to keep cool in summer. The combination of large, poorly insulated buildings, heat-generating machinery, and high occupancy creates conditions that can quickly become uncomfortable and even hazardous. For production managers and facility teams, finding an effective and sustainable cooling solution is essential — not just for comfort, but for performance and compliance.

Why Heat Is a Productivity Problem

The relationship between temperature and workplace performance is well established. Studies have consistently shown that productivity begins to decline when ambient temperatures exceed around 24°C, with error rates increasing and output falling as temperatures rise further. In manufacturing, where precision, consistency, and pace are critical, this can have a measurable impact on output quality and overall efficiency.

High temperatures also increase fatigue and reduce concentration, raising the risk of accidents and near misses. This is a particular concern in environments where workers operate heavy machinery, handle hazardous materials, or carry out repetitive physical tasks.

Legal Obligations for Employers

UK employers have a legal duty of care regarding workplace temperature. While there is no statutory maximum workplace temperature in UK law, the HSE's guidance makes clear that employers must take reasonable steps to achieve a comfortable working temperature. This includes considering the provision of fans, cooling systems, or other appropriate measures during hot weather.

For pharmaceutical manufacturing and food production environments, specific temperature standards must also be met for product quality and regulatory compliance — making climate control a business-critical requirement rather than simply a welfare consideration.

Choosing the Right Cooling System for a Manufacturing Facility

The ideal solution depends on the specific characteristics of the facility. For large open-plan production floors, evaporative cooling typically delivers the best combination of performance and energy efficiency. EcoCooling systems supply a continuous flow of fresh, cooled air across the entire space, using up to 90% less energy than conventional air conditioning.

For enclosed areas, clean rooms, or zones requiring precise temperature control, split systems or VRF air conditioning may be more appropriate. In larger facilities, a combination of technologies often delivers the most effective overall result.

Zero-Downtime Installation

One of the key concerns for manufacturing businesses considering a new climate control system is disruption to production. At Celsius Design, all installations are carried out with zero downtime as standard. Our engineers work around your production schedule to ensure operations continue uninterrupted throughout the installation process.
