Recover and save energy

As much as 90% of the electrical energy used by a compressed air system is converted into heat. Using Atlas Copco's integrated energy recovery systems, you can recover up to ≈ 75% of that power input as hot air or hot water without any adverse influence on the compressor's performance. Through efficient usage of the recovered energy, you generate important energy cost savings and a high return on investment.

Applications

● Auxiliary or main heating of warehouses, workshops...

● Industrial process heating.

● Water heating for laundries, industrial cleaning and sanitary facilities.

● Canteens and large kitchens.

● Food industry.

● Chemical and pharmaceutical industries.

● Drying processes.
