Powering Heavy Industry with Reliable, High-Efficiency Compressed Air

Customer Background
The customer is a leading general manufacturing enterprise with multiple production lines operating around the clock. Their operations span automotive component machining, heavy equipment fabrication, and metal forming – all of which demand a continuous, high-volume supply of clean, dry compressed air. With rising energy costs and increasing pressure to meet national carbon reduction targets, the plant sought an air compression solution that could deliver both exceptional reliability and measurable efficiency gains.

Solution
We installed three LU160 oil-injected, fixed-speed screw compressors (160 kW each). These work-horses are designed for heavy-duty continuous operation:

Total air delivery: up to 28.0 m³/min per unit at 8 bar – combined capacity easily covers peak demand.

Direct drive, simple construction – fewer components mean high reliability and easier servicing.

Built-in heavy-duty air filter and efficient oil separator ensure oil carryover ≤3 ppm, meeting industrial air quality standards.

Noise level kept below 78 dB(A) with standard acoustic enclosure.

All three units run in parallel with automatic load-sharing control, providing redundancy and stable system pressure.

Results

Uninterrupted production – no unscheduled downtime since commissioning.

Cost-effective – lower initial investment and maintenance costs compared to variable-speed alternatives, while still achieving good part-load efficiency via intelligent on-/off-load control.

Easy maintenance – routine oil and filter changes are straightforward, with clear indicator lights for service alerts.

Workshop-friendly – compact footprint and standard foundation requirements simplified installation.

Training & Support
Our team provided on-site operation and maintenance training for the plant’s engineers, covering daily checks, oil replacement, filter cleaning, and safety procedures – empowering them to keep the system running at peak performance.
