ZD Series: Compact Air and Nitrogen Boosters
Our ZD (VSD) hybrid solution combines the advantages of oil-free screw technology, rotary‑drum adsorption dryers, and the well‑known piston‑type booster compressor technology.
Therefore, it can supply oil-free dry air or nitrogen for medium- and high-pressure applications such as the following:

• PET Industry: Bottle Blowing
• Instrument air supply
• Natural nitrogen export capture
• Air source for the soot-blowing device
The ZD system is easy to install and use: no complex connections or foundations are required. The Z compressor and D booster can be operated in parallel or independently, and they can achieve a wide range of pressure ratios (between 25 and 40 bar), helping you save on maintenance time and costs.
Four-stage air compression with an efficient intercooler can significantly enhance compression efficiency. By retrofitting variable-speed drives (VSDs) and energy recovery systems, additional energy savings can be achieved.


Hybrid technology
ZD integrates well-known oil-free screw compressor, desiccant air dryer, and booster technologies into a single unit.
Specifically designed to enhance the efficiency and reliability of compressed air systems.


Low maintenance costs
By leveraging a hybrid system design, ZD has reduced the number of components, which helps extend component life, increase maintenance intervals, and lower maintenance costs.


Air purity
The ZD booster compressor has been certified oil-free to ISO 8573‑1 Class 0, ensuring that no oil contamination enters your air or nitrogen system and minimizing the risk of product contamination.


Energy Efficiency of Compressors and Boosters
Save energy through compressor technology
Compared with a three-stage piston design, a four-stage compressor with an intercooler offers higher compression efficiency.
The MD dryer can also enhance the compressor’s compression efficiency.
Energy Reuse
With the optional heat recovery system, you can utilize the hot water generated by your production system for boilers, sprinklers, and cleaning processes, thereby reducing energy costs.
VSD is more energy-efficient.
Variable-speed drives enable ZD units to achieve an average energy efficiency that is 35% higher than that of fixed-speed compressors. Furthermore, by leveraging the waste heat from compression in MD dryers for the drying process, additional energy savings can be realized.
