1.High-Efficiency Energy-Saving Two-Stage Compression Unit

Our two-stage (series or parallel) screw compression unit redefines efficiency by splitting compression into two optimized phases:

Stage 1: Compresses intake air to an intermediate pressure, with heat absorbed by cooling lubricant.

Stage 2: Further compresses pre-cooled air to the target pressure, aided by atomized cooling injection for near-isothermal compression.
Result: Achieves up to 15% energy savings vs single-stage systems.

Precision Engineering: Rotors undergo 20-step precision machining for flawless profile accuracy and reliability.

2. Reduced Bearing Load for Extended Lifespan

Two-stage compression lowers the compression ratio, significantly reducing bearing stress. Paired with heavy-duty SKF bearings, our design ensures:

✔ 30% longer service life vs conventional compressors

✔ Stable operation under extreme loads
✔ Minimal maintenance downtime

3. Interstage Cooling Innovation Darko patented interstage cooling system boosts efficiency through:

Atomized Cooling Spray: Instantly absorbs heat after Stage 1 compression, eliminating the need for bulky intercoolers.

Energy Recovery: Pre-cools air before Stage 2, slashing compression power demand by 18%.
Key Advantage: Compact design with no performance trade-offs.
