ZDR Series Steam-Electric Marine Hot Water Storage Tank: Efficient Fresh Water Heating Solution for Ships and Platforms
The ZDR Series Steam-Electric Marine Hot Water Storage Tank is expertly designed for heating fresh water on ships and offshore platforms, ensuring a steady supply of hot water (up to 65℃) for crew use. This marine hot water tank is an essential component in maritime fresh water heating systems, providing reliable and efficient performance in demanding marine environments.
Working Principle:
The hot water tank operates by connecting its water inlet to a pressure water tank. Fresh water, initially at approximately 15℃, fills the calorifier system and is heated within the cabinet by the system’s heater. The heated fresh water is then distributed throughout the ship, reaching a temperature of 65℃. The used water returns through the system’s backwater pipe to the hot water tank’s water pump inlet. The water pump periodically regenerates the water in the tank, which gradually cools, and the cycle repeats, ensuring continuous heating.
Key Features:
- High-Capacity Storage: Available in various capacities (0.12m³ to 1m³), the ZDR Series meets the diverse needs of marine fresh water heating systems.
- Steam-Electric Heating: Combines steam and electric heating for efficient and reliable performance, even in harsh marine conditions.
- Temperature Control: Precisely regulates water temperature from inlet (15℃) to outlet (65℃), ensuring optimal comfort for crew members.
- Safety Mechanisms: Incorporates a safety valve with an open pressure of 0.42 MPa, ensuring safe operation under design pressure conditions.
- Durable Construction: Features a 40mm external thermal layer and a 0.7mm outer galvanized sheet steel casing for enhanced durability and insulation.
