5. Exceptional Indicating System: Equipped with indicators for ready-to-start, manual start, automatic start, unit operation, unit shutdown, and battery charging. Additionally, it alerts you on speeding, lubrication oil low pressure, turbocharger low pressure, engine lubricating oil low temperature, cooling system high water temperature, battery low voltage, low fuel level, and regular inspections.
6. Superior Alarm and Protection System: Stay safeguarded with alarms for failure start after three attempts, overspeed, low lubrication oil pressure, turbocharger low oil pressure, high cooling water temperature, low lubricating oil temperature, automatic charging device failures, low and high battery voltage, and low fuel level.
7. Comprehensive Display Systems: Offers visibility into engine oil pressure, engine speed, battery charge current, and battery charging voltage, ensuring informed operation.
8. Innovative Direct-Coupled Design: Featuring a high-flexible coupling between the diesel engine and water pump, all on a common channel base, this compact structure promises superior overall performance, minimal failure and vibration, and easy on-site construction installation.
9. High Pressure and Large Flow Capacity: Choose from IS series single-stage single-suction, SOW series single-stage double-suction, and SHD series segmental multistage pumps to accommodate diverse fire scenarios, delivering exceptional performance.
10. Adjustable Flow and Working Pressure: With mechanical or electronic speed governors, adjust the diesel engine's speed to ensure pump flow and head align with actual data for enhanced precision.
11. Advanced Water Temperature Pre-Heating Device: Equipped with an AC220V cooling water pre-heating system, maintaining optimal operational conditions even in environments below 5 ºC.
12. Dual Battery Circuit: Should one battery fail, rest assured the other will automatically take over, ensuring uninterrupted operation.
13. Maintenance-Free Battery: Enjoy the convenience of maintenance-free operation, eliminating the need for frequent supplemental fluid additions.
14. Automated Timing Inspection Test: While in standby mode, the unit autonomously performs condition tests and provides timely alerts for any necessary standby condition adjustments.
Note: The above functionalities are thoughtfully designed to be adaptable to user preferences, ensuring that every need is met with precision and care. Furthermore, we offer bespoke customization services, enabling us to tailor designs to meet the unique and specific requirements of our esteemed clientele.
