Why choose a 5:6 asymmetric twin-screw compressor over conventional compressors?

> Key Value Proposition:
> - 20% higher efficiency: Reduced rotor leakage, IPLV ≥ 6.0 (30% less power vs. reciprocating chillers)
> - Extended lifespan: 100,000-hour design life (vs. ≤60,000 hrs for reciprocating)
> - Ultra-low failure rate: <0.5%/year (industry avg. ≥2%)
> Ideal for: 24/7 facilities like factories/data centers

How does the PLC control system reduce operational costs?

> Smart Management:
> - Remote monitoring cuts on-site inspections by 80%
> - Automatic cooling output adjustment (30%-100% seamless capacity control)
> - BACnet/MODBUS compatibility (zero-cost integration with BAS)

What operational benefits does the bilingual touchscreen provide?

> Efficiency Gains:
> - One-touch start/stop (training time reduced from 2 weeks to 1 day)
> - Dual-language fault codes (diagnose issues 2+ hours faster)
> - Automated maintenance reports via data export

Are international valves (Emerson/Danfoss) worth the premium?

> TCO Validation:
> Metric :Local Valves ; Int'l Valves
> Service Life: 3-5 years; 8-10 years
> Leakage Rate: ≤2%/year; ≤0.5%/year
> Temp. Accuracy: ±1℃; ±0.3℃
> Critical for pharma/semiconductor precision processes

Is IPX22 protection sufficient for chemical plants?

> Protection Options:
> - Standard IPX22: Vertical water resistance (general equipment rooms)
> - Optional IP54: Dustproof + water jet protection (recommended for chemical plants/coastal areas)
> - Corrosion-resistant coating (H₂S/Cl₂ resistance)

How does the "12-safeguard system" prevent downtime losses?

> Critical Protections:
> - Instant shutdown: Stops within 0.5 seconds of water flow interruption
> - Predictive alerts: Compressor winding overheating warning (6-8 hrs pre-failure)
> - Dual redundancy: Backup power protection modules
> Field data: ≤5 mins unplanned downtime/year (Tier-4 data centers)

Do you support legacy system retrofits? What's the timeline?

> Retrofit Solution:
> - Reuse existing towers/pumps: Chiller-only replacement (≤3 working days)
> - Standardized interfaces: Flanges compliant with ASME B16.5
> - Performance guarantee: 30% energy savings or cost compensation
