If you're operating an air compressor, you'll want to take advantage of heat energy recovery. This process essentially reuses around 75% of waste hot air or water for running radiators, laundries, canteens and kitchens, and ducting. When properly executed, you'll be able to use your air compressor to offset energy costs from external suppliers.

As with a lot of equipment, the initial cost of investment is offset by total savings throughout its lifespan. The return on investment for energy recovery is generally 1-3 years. Many factors contribute to this estimate including facility size and age of equipment. With the right setup, you can nearly become your own heat power plant.

The savings with heat recovery are substantial. Especially considering electricity expenses make up around 80% of owning and operating an air compressor, and around 90% of energy is converted into heat. Adding to this, it's fairly easy to move excess hot air and water throughout your facility.

How heat energy recovery works

Essentially, energy recovery transfers the waste heat from an air compressor through your pipe or air duct network. Made possible by heat exchangers, valves, and other components, there are different variations depending on whether your air compressor is air-cooled or water-cooled.

When operating air-cooled air compressors, the energy recovery potential depends on the workload. This statement is especially relevant if you're operating a variable speed drive (VSD) machine. Typically, with these types of machines, heat is taken directly from the exhaust or an air to heat exchanger is used. This hot air is then used to keep a facility warm.

Also known as airborne energy recovery, hot air is usually fed through a duct system to circulate it throughout the desired premises. This is especially helpful for those working in colder climates, and who don't want to spend a lot on heating costs. It's a great way to keep expenses fixed with fluctuating oil and gas prices.

On the other hand, there are water-cooled compressors. These machines provide more flexibility in terms of how the heat is distributed. Usually, it's fed into radiator pipes. Additionally, excess hot water can be used to fill a boiler to offset the time it takes to reach desired temperatures. This applies to compressors with a temperature of up to 90° C.

Environmental impact

As emissions regulations become stricter, the environmental impact of your operations is more important than ever. As an example, heat energy recovery technology could save 1.99% of the total energy consumption in the UK. This statistic equates to fueling around 913,000 diesel/petrol cars.

In one case, a car manufacturer was able to reduce its CO2 emissions by 260,000 tons per year. This resulted in savings of around €43.500 yearly.  Also, a large operation consuming over 500 kW at more than 8,000 hours per year consumes more than 4 million kW annually. These figures are based on the huge impact air compressor systems have on industrial manufacturing.

The right equipment

For optimal results, you can either invest in an air compressor with built-in energy recovery or an external EnergyBox. With an advanced VSD air compressor like the RMC IVR, you can expect to recover 75% of the energy used. The EnergyBox claims to reuse up to 80% of thermal heat.

If you're investing in new equipment, it might make the most sense to go with a VSD compressor with integrated energy recovery. This is because this type of machine comes with additional efficiency features to ensure you're using as little electricity as possible. However, the best decision will depend on your actual needs and industrial application(s).
