Efficiency
u003cpu003eTypically, the investment and installation of a compressor represents about 15% of the total life cycle cost of a compressor, calculated over 10 years. Maintenance represents another 15%, while the energy consumption represents 70%. It is easy to understand that energy efficiency is important. Every percent that can be gained in efficiency will have a direct impact on the life cycle cost of youru003c/pu003eu003cpu003e compressor. While being utterly reliable, our ZT 15-55 (VSD) and ZR 30-55 (VSD) are also competitive in terms of efficiency. These are the highest contributors to the efficiency of this machine range:u003c/pu003e
u003cpu003eu003cstrongu003eVariable Speed Driveu003c/strongu003ennA Variable Speed Drive (VSD) compressor automatically adjusts itsu003c/pu003eu003cpu003e motor speed to the air demand. Applications have a varying airu003c/pu003eu003cpu003e demand. That is why Atlas Copco pioneered the Variable Speedu003c/pu003eu003cpu003e Drive (VSD) technology for compressors to make sure that youru003c/pu003eu003cpu003e system gets the right amount of air.u003c/pu003e
