DRG-2.0 Marine Domestic Hot Water Tank | High-Capacity Shipboard Hot Water Heating System
Product Overview: Professional Marine Electric Calorifier for Vessel Hot Water Supply
The DRG-2.0 Marine Domestic Hot Water Tank delivers reliable and efficient hot water generation for maritime applications through advanced electric heating technology. This high-capacity system ensures a consistent supply of heated freshwater for all onboard domestic requirements, featuring robust construction and intelligent temperature management designed specifically for marine environments.
Operational Principle: Marine Hot Water Generation System
1. Automatic Heating Process
-
Integrated connection to vessel pressure water tank receives freshwater supply at approximately 15°C
-
Advanced electric heating system efficiently raises water temperature to optimal 65°C
-
Continuous hot water distribution throughout vessel for all domestic applications
2. Recirculation & Temperature Maintenance
-
Dedicated return line connection to hot water tank pump inlet
-
Automated pump operation maintains consistent water temperature
-
Continuous circulation prevents temperature drop in distribution systems
-
Energy-efficient reheating of cooled return water
