These vacuum pumps consume approximately 50% less energy than alternative technologies. They are among the most energy-efficient oil-lubricated vacuum pumps on the market in the capacity range where some other technologies (e.g. oil sealed vane) start to become inefficient mechanically and expensive in terms of capital expenditure. As much as 90% of the electrical energy used by a vacuum solution is converted into heat. With Atlas Copco’s integrated energy recovery system, it is feasible to recover up to 75% of that power input as hot air or hot water without any influence on the machine’s performance. Through efficient usage of the recovered energy, you bring about important energy cost savings and obtain a high return on investment.
