Electric Heating Hot Water Tank

Application

This series hot water tank is suitable for heatingwater on the ship or platform, heated fresh water for crew use.

Principle Description

This series hot water tank can be combined to use with fresh water pressure tank on board,namelyuse fresh

waterto renew the stock of hot watertank,and then heated by electric for usage of entire vessel.

MainComponents

Temperature controller: The water temperature in tank is controlled by two WTZK-50-C pressure type temperature controllers; If the water temperature in tank is lower than 50 centigrade,

the power will be on automatically and the electric heater will begin to heat; If the water temperature in tank is

higher than 65 centigrade, the power will be off automatically and the electric heater will stop heating.

Pressure gauge: To show the pressure in tank

Thermometer: To show the water temperature in tank.

Safety valve: If the pressure in tank is more than 0.42MPa, the safety valve will open to release the pressure in tank.

Note: Never wind the raw material belts into the inlet of safety valve when installing the safety valve.

Float level Switch: To protect the electric heater, if the liquid level in tank is lower than float level switch, the

electric heater will cut off automatically.

Electric control box

There two kinds of hot water controlling: Manual control and auto control. When the change-over switch SA2 is turned to "Manual", the electric heater will start to heat until the water in tank reaching 65 centigrade,

Then the electric heater stops heating. When the change-over switch is turned to "Auto", at this moment, if the water temperature in tank is lower than 50 centigrade,

the electric heater will start to heat automatically until the water in tank reaching 65 centigrade, . Then the electric

heater stops heating. If the float level switch finds that there is no water in hot water tank, the electric heater

controlled by electric control box will not work. For the hot water tank which has two or three groups of electric

heater, the device will adopt segmentation heating method to realize due to the large power of electric heater.

1min later, another group electric heater will start to work. By that analogy, all of the electric heater will stop heating

after the water in tank reaching 65 centigrade.
