Value-Added Solutions
Legacy System Upgrade Path
·Retrofit kits for old housings (ISO 52134 adapter)
·3-stage transition:
Mechanical → LoRa remote → AI leakage alert
Lifecycle Cost Revolution
·Traditional 20-year cost distribution:
Initial purchase (15%) + Installation (10%) +
Maintenance (25%) + Leakage loss (50%)
·2026 Solution: Predictive maintenance reduces leakage loss to 12%
Deliverables & Compliance
| Stage | Output | 2026 Enhancement |
