DRG – 2.0 Marine Domestic Hot Water Tank
The DRG – 2.0 Marine Domestic Hot Water Tank is a cutting – edge marine electric calorifier that leverages advanced electric heating technology to offer dependable and highly efficient hot water generation for a wide range of maritime applications. With its large – capacity design, this system guarantees a steady and uninterrupted supply of heated freshwater to meet all onboard domestic needs. It is built with a robust structure and incorporates intelligent temperature management features, all specifically tailored to thrive in the challenging marine environment.
Operational Principle: Advanced Marine Hot Water Production System
1. Automatic Heating Mechanism
- Freshwater Intake: It has an integrated connection to the vessel’s pressure water tank, which supplies freshwater at around 15°C.
- Efficient Heating: The state – of – the – art electric heating system quickly and effectively raises the water temperature to the ideal 65°C.
- Uniform Distribution: The heated water is then continuously distributed throughout the vessel to cater to all domestic applications, such as showers, sinks, and laundry facilities.
2. Recirculation & Temperature Stabilization
- Return Line Linkage: There is a dedicated return line connection to the hot water tank pump inlet.
- Automated Pump Function: The automated pump operation ensures that the water temperature remains consistent at all times.
- Continuous Flow Advantage: Continuous circulation of the hot water prevents any significant temperature drop in the distribution systems, maintaining a comfortable and reliable hot water supply.
- Energy – Saving Reheating: The cooled return water is reheated in an energy – efficient manner, reducing overall energy consumption.
Technical Specifications: DRG – 2.0 Marine Water Heating System
