Electric Heating Calorifier

DRG Series Electric Heating Calorifier | Marine-Grade Hot Water System with Automatic Temperature Control

Product Overview: Advanced Marine Electric Heating Calorifier
The DRG Series Electric Heating Calorifier delivers reliable hot water solutions for maritime applications through advanced electric heating technology. Designed for seamless integration with vessel freshwater pressure systems, this professional-grade calorifier automatically replenishes from your ship’s freshwater tank and heats it to optimal temperatures for all onboard domestic requirements. Featuring fully automated operation and comprehensive safety systems, our marine calorifier ensures consistent hot water supply while maintaining maximum energy efficiency.

Smart Temperature Control System:

Dual Temperature Controllers: Utilizes two WTZK-50-C pressure temperature controllers for precise regulation
Automatic Heating Activation: Powers heating elements when water temperature drops below 50°C
Intelligent Shut-off: Automatically stops heating when temperature reaches optimal 65°C
Visual Monitoring: Integrated pressure gauge and thermometer for real-time system monitoring
Safety Pressure Release: Specialized safety valve activates at 0.42MPa to prevent over-pressurization

Important Safety Note: Never introduce raw material tapes into safety valve inlet during installation to ensure proper operation.

Advanced Protection Features:

Float Level Switch Protection: Automatically cuts power to heating elements when water level drops below safe operating minimum
Dual Control Modes: Manual and automatic operation settings for flexible management
Segmented Heating Technology: For units with multiple heating elements, implements staggered activation to manage power load efficiently
Dry-Fire Prevention: Comprehensive system protection against operation without adequate water supply
