Key Fact (2023 China Agricultural Machinery White Paper):
Industry average AC failure rate: 35% → Xinrun equipped machinery: 11.7% (Exactly 1/3 of industry mean)
I.The Truth Behind 35% Failure Rate: Three Flaws in Conventional Design
Empirical Evidence (National Agri-Machinery Inspection Center Report No.NJ2023-086):
1.Overcrowded Fins
- Standard 3-4mm fin pitch→ 62%straw jamming rate (fails to block >5cm debris)
- Air resistance surges to 320Pa(2.1× over design limit)
2.Poor Corrosion Resistance
- Galvanized steel fins: 38% perforation rate in 2 years(Dongying, Shandong field data)
3.Ineffective Dust Removal
- Manual cleaning: 15 minutes/session→ Daily productivity loss: 2.5 hours(Zhoukou user survey)
II.Xinrun’s Solution: Triple Innovation in Wide Fin Pitch System
Technology Architecture:
Wide Fin Pitch (Physical Anti-clog) + Nano-Ceramic Coating (Anti-corrosion) + Intelligent Cleaning (Active Maintenance)
Technical Breakthroughs:
✅ 5-7mm Fin Pitch
- Pitch enlarged to1.5-2× conventional→ Blocks ≤5cm straw (Jamming rate↓ 82%)
- CFD-optimized airflow → Heat dissipation + 18%(at identical air volume)
✅ Nano-Ceramic Coating (ISO 9227 CX Grade)
- 720-hour salt spray resistance(Industry avg: 480 hrs)
- Surface hardness HV 580(Galvanized steel: HV 120)
✅ Bidirectional Auto-Cleaning
- Daily Mode: 1,200rpm forward rotation→ Removes loose dust (Energy:0.2kWh/cycle)
- Deep Mode: –800rpm reverse + pulsed air→ Clears embedded debris (Cycle: 30 seconds)
III.Field Verification: 120 Machines Across 4 Provinces
Test Conditions:
- Equipment: Lovol GOSUM GK-Series Harvesters (same batch)
- Regions: Henan/Shandong/Xinjiang/Heilongjiang (Major agricultural zones)
- Duration: 2023 Harvest Season (60 days)
Failure Rate Comparison:
Failure Type | Conventional AC | Xinrun System | Reduction |
Radiator Clogging | 28.3% | 3.1% | -89% |
Fin Corrosion | 5.2% | 0.4% | -92% |
Compressor Overheat | 1.5% | 0.2% | -87% |
Total Failure | 35.0% | 3.7% | -89.4% |
Note: 11.7% total failure rate for 5,000 Xinrun-equipped machines (including other components) remains 1/3 industry average.
IV.Economic Impact: Saving ¥12,000/Machine/Year
Cost Analysis (Zhoukou Client, 120 operating days/year):
Item | Conventional | Xinrun | Savings |
Radiator Replacement | ¥1,800/year | ¥0 | ¥1,800 |
Downtime Loss (¥200/h) | ¥60,000 | ¥6,000 | ¥54,000 |
Manual Cleaning Labor | ¥4,800 | ¥0 | ¥4,800 |
Compressor Energy | ¥8,640 | ¥6,480 | ¥2,160 |
Total | ¥75,240 | ¥12,480 | ¥62,760 |
Client Testimonial:
“Xinrun’s AC gave my harvesters zero downtime during the 120-day season, saving over ¥20,000 in fuel alone!”
