Evaporative Cooling

The most efficient and environmentally friendly temperature relief for commercial and industrial environments

Find out how much you can save with on your site with our Evaporative Cooling vs. Air Conditioning Cost Comparison Calculator.

Evaporative air cooling provides the most energy efficient temperature relief for commercial or industrial environments of any scale.

Up to 80% more economical than conventional air conditioning systems, our award-winning evaporative cooling systems have delivered proven cost reductions and operational returns throughout the manufacturing, food and beverage, IT, retail, health and education industries.

Here at Cosaf, we’re not only world leaders in clean, green heating, ventilation and air conditioning technology, but also the pioneers and unrivalled experts in the design and installation of evaporative cooling solutions in the UK.

Why evaporative cooling?

Evaporative cooling (EC) is to date the most energy efficient and environmentally friendly climate control system used for temperature regulation within commercial and industrial environments.

The method presents a number of benefits over traditional AC systems, including:

  • Better energy efficiency – you could be looking at saving anything up to 80% of your energy costs
  • Introduces 100% fresh air – reducing the risk of poor indoor quality and air pollution
  • Allows for open doors and windows
  • Lower initial and ongoing costs – up to 50% less to purchase and capable of cutting maintenance and repair costs by more than half
  • No use of high GWP refrigerant gases

The ultimate F-Gas solution

The F-Gas regulations lead to a 60% price increase of refrigerant gases last year, with a further 40% increase for high GWP gases, such as R32. The most important F-Gas facts that you need to be aware of:

  • High GWP gases are being phase out
  • >150 GWP is banned from 2022
  • From 2025 existing systems and maintenance re-gas would be included
  • Cost is already spiralling out of control
  • Demand has already outstripped supply

What is GWP?

  • GWP stands for Global Warming Potential
  • GWP of 1 = 1 kg of CO₂
  • R410A has a GWP of 2088
  • 1kg of R410A = 2088 kg of CO₂ to the atmosphere
  • The equivalent of 15,000 miles driven in the average diesel car in the UK

Why is R32 not a viable long-term option?

  • >150 GWP
  • A2L restrictions on application

Evaporative cooling is the ultimate solution to the F-Gas challenge. Our clean, green systems require no use of harmful to the environment refrigerant gases and use 80% less energy to operate when compared to air conditioning systems.

How much will evaporative cooling cost and how much will I save?

In reality evaporative cooling

In reality evaporative cooling could:

  • Cost you up to 50% less than traditional air conditioning systems, due to the simplistic design of the technology
  • Deliver up to 80% lower energy usage; and
  • Save you huge amounts of money in terms of maintenance, as this can be done in-house by your team following training.

However, don’t take our word for it. Calculate how much you could save by implementing an evaporative cooling system on your site with our quick and easy to use Evaporative Cooling Cost Comparison Calculator
