ZDR-0.2 Electric and Steam Heating Water Tank

ZDR-0.2 Electric and Steam Heating Water Tank

1. ZDR-0.2 Electric and Steam Heating Water Tank Application
This series heating water tank is suitable for heating fresh water by electricity or steam on the ship or platform, heated fresh water for crew use.

2. ZDR-0.2 Electric and Steam Heating Water Tank Operation method
(1) Adjust the temperature control range.
     Set the low temperature and high temperature of temperature regulating valve to 50℃ and 60℃ separately.
     Set the low temperature controller and high temperature controller to 50℃ and 65℃ separately.
(2) Set the open pressure of safety valve
     Set the open pressure of safety valve. When the pressure in tank is over 0.42MPa, the safety valve will take off to release the pressure in tank.
(3) Normal operation
     Open the water inlet and outlet valve. Start the electric heater. When the temperature in tank is lower than 50℃, it will start automatically until the temperature reaching 65℃.
     If using the steam heater, start the temperature regulating valve. When the temperature in tank is lower than 50℃, it will open automatically until the temperature reaching 60℃. Then close.
     If using the electric heater, start the electric heater. When the temperature in tank is lower than 50℃, it will open automatically until the temperature reaching 60℃. Then close.
