10. Adjustable Flow and Working Pressure: Diesel pumps equipped with mechanical or electronic speed governors allow adjustable engine speed, precisely aligning pump flow and head with actual conditions.
11. Water Temperature Pre-Heating Device: An AC220V cooling water pre-heating device ensures optimal operation in environments below 5 ºC, providing reliable performance in colder conditions.
12. Dual Battery Circuit: In the event of a battery failure, the secondary battery automatically activates, ensuring uninterrupted performance.
13. Maintenance-Free Battery: Enjoy peace of mind with maintenance-free batteries, eliminating the frequent need for supplemental fluid.
14. Automatic Timing Inspection Test: In the realm of fire protection, our systems are typically in a vigilant standby mode. The unit is engineered to autonomously conduct device testing to ensure readiness, providing timely alerts when conditions deviate, thereby safeguarding your peace of mind.
Note: The aforementioned functionalities are available for customization based on user preferences. We are adept at designing tailor-made solutions to meet your specific requirements, ensuring optimal performance and satisfaction.
