Atlas Copco Oil-free medium pressure screw compressor with high pressure piston booster ZD (VSD)
Four -stage compression with intercooling is more efficient than three-stage piston designs. The MD dryer also improves the compression efficiency of the booster.
ZD is a combination of well-known oil-free screw, adsorption dryer and booster technology. Designed to increase system efficiency and reliability.
Re-use your energy
Thanks to the optional heat recovery unit, you can reduce energy cost by using the hot water generated in your production system by boilers, showers, cleaning processes.
ZDs are ISO 8573-1 Class 0 certified, which means no oil will enter your air or nitrogen network, minimizing product contamination risk.
Low maintenance costs
Thanks to the hybrid system design, the ZD reduces the number of components which increases component lifetime, extends maintenance intervals and reduces maintenance costs.
VSD for more savings
The Variable Speed Drive makes the ZDs on average 35 % more energy-efficient than fixed-speed compressors. MD dryer uses the heat of compression for further savings.
