Up to 94% of the energy used by air compressors can be recovered and reused through heat recovery systems, maximizing efficiency and reducing waste.
What is waste heat recovery and how does it work?
First of all, what is a heat recovery system? Every air compressor generates heat during operation, and instead of letting this heat go to waste, heat recovery systems capture and reuse it, for example to heat water for industrial processes or heat your facilities during the colder months.
By integrating a heat recovery system, you transform wasted energy into usable heat, reducing your dependence on external energy sources.
Why waste heat recovery matters for your energy consumption
Research shows that 94% of the energy consumed by air compressors is recoverable.
For example, this means that heat recovery could save 1.99% of total industrial energy consumption in a country such as the United Kingdom. This is equivalent to removing 913,000 diesel or gasoline cars from the road each year!
Therefore, implementing heat recovery is not only beneficial for your bottom line, it’s also an important step towards better management of energy consumption.
Slash energy costs with heat recovery
Did you know? Compressed air systems account for 12% of manufacturers' total energy costs, and can even reach up to 40% in some cases. Given that 94% of this energy is recoverable, the potential for savings is enormous.
Here is an example of a specific case involving one of our clients.
A British car manufacturer installed a heat recovery system to heat the water used in production. Results:
- Reduction in CO₂ emissions of 260,000 tons/year
- Annual savings of €43,473
When energy costs account for 80% of air compression expenses, these savings are truly game-changing.
FAQs
Heat recovery systems can lead to significant cost savings. For instance, one manufacturer saved €43,473 per year by using recovered heat for production processes.
