Oil-free screw compressor
Our OIL FREE series oil-free screw compressor adopts variable frequency open-loop vector control technology, delivering 100% pure oil-free compressed air that meets ISO 8573-1 Class 0 air quality standard.
Equipped with integrated TCO waste heat regeneration dryer as an optional matching system, the whole unit realizes zero extra energy consumption for air drying. It features ultra-low temperature rise, precise pressure control and soft start design, supporting long-time stable low-frequency operation for continuous production lines in food, pharmaceutical, electronics and chemical industries.
Core Advantages of Oil-Free Screw Compressor
- Ultra-low temperature rise design
The optimized cooling structure ensures stable long-term running under low frequency working conditions, effectively avoiding overheating shutdown during 24h continuous production.
- Open-loop vector variable speed control system
Faster response and highly precise speed regulation, automatically adjust air output according to real-time gas consumption to cut idle energy waste.
- High efficiency under low load
The unit maintains high energy efficiency even when the frequency is reduced by more than 50%, greatly lowering overall power consumption for factories with fluctuating air demand.
- Ultra-stable output pressure
Precise pressure control system limits pressure fluctuation within 0.01MPa, protecting precision production equipment from unstable air pressure damage.
- Soft start performance
Soft starting mode eliminates large starting current impact, reduces power grid load and cuts extra energy consumption during startup.
Supporting TCO Waste Heat Regeneration Dryer
- No pre-filter required at dryer inlet, simplify pipeline layout and reduce pipeline pressure loss.
- Zero extra energy consumption: desiccant regeneration only uses waste heat from compressor operation, no additional heating power needed.
- No purge air loss during regeneration, maximizing effective air output for production.
- Large diameter pipeline design, pressure loss only 0.1–0.2 bar, no waste of compressed air energy.
