Frequently Asked Questions (FAQ)

1. What is the expected lifetime of a Screw Compressor in harsh environments?

A DECHUAN Heavy Duty Screw Compressor is designed for 24/7 continuous run under high dust, vibration, and high-ambient temperature conditions. With SKF large bearings, low-speed rotors, and industrial-grade materials, the MTBF (Mean Time Between Failures) can exceed 50,000 operational hours when properly maintained.

2. How does the compressor handle high-temperature and dusty conditions?

The features:

Dual dust filters to remove >99% of particulates.

Independent cooling systems rated up to 50°C ambient temperature.

Thick steel casings and vibration-resistant mounts.

These components ensure reliable operation in mining, cement, and steel plant environments without frequent thermal trips.

3. Can multiple  Screw Compressors be connected in one plant system?

Yes. DECHUAN units support multi-machine integration (2–6 compressors in parallel) with load-matching and VSD control. This allows your factory air system to scale according to demand while maintaining energy efficiency and stable pressure.

Why Choose Screw Compressor for Extreme Environments?

• SKF large bearings and low-speed rotors reduce wear and vibration.
• Dual dust filters and thick steel casings protect internal components.
• Cooling systems rated for 50°C high ambient temperatures prevent thermal trips.
• Precision factory manufacturing ensures repeatable, high-quality performance.
