ZD (VSD) oil-free medium pressure screw compressor
Four-stage compression with intercooling is more efficient than a three-stage piston design, and the MD Dryer also increases the compression efficiency of the booster .
The ZD series oil-free medium-pressure screw air compressor integrates oil-free screw technology , adsorption dryer and booster technology , and its design can improve system efficiency and reliability.
With the optional energy recovery system , hot water from the production system can be used for boilers, showers and cleaning processes, reducing energy costs.
Ingersoll Rand ZD (VSD) oil-free medium pressure screw air compressors are certified ISO 8573-1 CLASS 0 oil-free, which means that oil will not enter your air or nitrogen system, thereby reducing the risk of product contamination smaller.
With hybrid system design, ZD (VSD) oil-free medium pressure screw air compressor reduces the number of components, which helps to improve component life, extend service intervals and reduce maintenance costs.
The variable speed drive makes the ZD (VSD) oil-free medium pressure screw compressors 35% more efficient on average than fixed speed compressors. Further energy savings can be achieved by having the MD dryer utilize the heat of compression for drying.
industry
Our ZD (VSD) hybrid solutions combine the advantages of oil-free screw technology, drum-type adsorption dryers and the well-known piston booster technology. The end result is oil-free dry air for the following medium and high pressure applications:
- PET industry: bottle blowing
- Instrument air
- Natural Nitrogen Export Capture
- Air source for sootblower
The ZD system is easy to install and use: no complicated connections or foundations required. The Z compressor and D booster can be used in parallel or individually and can be used in a variety of pressure ratios (between 25 and 40 bar), saving you maintenance time and costs.
Four-stage air compression with high-efficiency intercooling increases compression efficiency. Additional energy savings can be achieved by adding a variable speed drive (VSD) and energy recovery.
