55 KW 75 Hp 30 Bar Permanent Magnet VFD Two-Stage Screw Air Compressor Energy Efficient Medium Pressure

Product Definition

The 25~30 bar two-stage PM VSD screw compressor delivers energy-efficient, precision-controlled medium-high pressure air – a modern replacement for traditional piston compressors in PET blowing, laser cutting, and heavy industrial applications.

Technical Specifications

Medium-Pressure 25–30 bar Two-Stage PM VSD Screw Compressor

• Dual-Stage Design – 15–20% Less Power Use – Cuts pressure load per phase, reduces bypass losses, and improves overall performance versus conventional single-stage systems.

• PM Variable Drive – 20–40% Extra Efficiency – Dynamically adapts motor output to fluctuating consumption. Total power reduction: 25–35% average, up to 45% under ideal conditions. Zero unloaded run time.

• Consistent 25–30 bar Supply – Produces 362–435 PSI reliably. Offers a robust substitute for traditional medium-pressure piston-type machines.

• Reduced Outlet Heat – Integrated cooling between phases lowers final thermal output, protecting critical components like bearings and seals – prolongs lifespan and reduces unexpected stoppages.

• Greater Output Per kW – Yields up to 15% additional free air delivery versus single-stage equivalents – raises capacity without requiring electrical infrastructure changes.

• Tight Pressure Tolerance (±0.1 bar) – Variable drive maintains outlet stability, removing pressure swings that compromise process consistency.

• Gradual Ramp-Up – Eliminates current spikes, minimizes grid strain, lengthens motor service intervals, and cuts demand-related fees.

• Quiet Performance – Diminished compression ratios and permanent-magnet motor design significantly reduce mechanical noise and vibration – suitable for sound-restricted workspaces.

• Heavy-Duty Endurance – Refined inter-stage airflow distribution guarantees steady functioning amid changing load conditions – delivers extended service life with reduced breakdown occurrences.

• Upgrade Over Piston Types – Delivers smoother running, fewer service requirements, and markedly superior energy performance compared to outdated medium-pressure reciprocating compressors.

  
  

Main Application Industries

• PET Blow Molding & Beverage Filling – Provides steady 25–30 bar pneumatic power for preform shaping. Even pressure delivery promotes consistent wall thickness and lowers scrap rates.

• CNC Machining & Laser Profiling – Supplies contaminant-free, pressurized gas for cutting heads and automated tooling. ±0.1 bar regulation preserves edge definition and machining accuracy.

• Geothermal, Mining & Quarrying – Runs down-the-hole hammers, percussive drills, and borehole equipment. Configurable as mobile units or fixed installations.

• Refining & Gas Processing – Actuates control valves, sensing instruments, and safety interlocks. Built for uninterrupted service in high-risk production zones.

• Hydroelectric Facilities – Feeds starting air to turbines, clears penstock lines, and supports station-wide pneumatic networks.

• Pharma & Edible Goods Manufacturing – Offers purified, stabilized high-pressure air for compacting tablets, encapsulating powders, and sealing food trays.

• Cement, Glass & Fabric Mills – Energizes air-slide conveyors, shuttleless looms, and float-glass forming lines.

• Industrial Workshops & Fabrication – Fits impact wrenches, media transfer systems, leak-detection rigs, and any operation requiring 25–30 bar supply.
