ZQ Series Roots Steam Compressor by MingTian ShanGu
Core Product Advantages
- Simple mechanical structure, stable continuous operation, high mechanical efficiency, convenient daily maintenance.
- Insensitive to dust, droplets and fibers inside conveying steam. Rotor working surface runs without lubrication oil; process gas keeps oil‑free, zero secondary oil pollution.
- Optimized sealing impeller design reduces internal leakage, realizes high‑efficiency & energy‑saving operation.
- Precision manufacturing assembly guarantees long service life and low failure rate under continuous heavy‑load working condition.
- Equipped with independent cooling system, protects high‑temperature components during unit shutdown.
