The atmospheric pressure electric hot water boiler is composed of a boiler body, a supporting control cabinet and a pipeline valve instrument. The design, manufacture, inspection and acceptance of this product shall be subject to the provisions of the "Safety Supervision Regulations for Small and Normal Pressure Hot Water Boilers" and "General Technical Conditions for Atmospheric Pressure Hot Water Boilers".

1. The working pressure of the atmospheric pressure hot water boiler is normal pressure, and the gauge pressure is 0 MPa. The designed feed water temperature is 85/65 ° C, and the thermal efficiency is not less than 98%.

2. The furnace body is made of boiler special Q235 steel plate to achieve safe use of the furnace body.

3. The electric heating tube shell adopts the standard SUS304 stainless steel seamless steel tube with high temperature resistance, corrosion resistance and good stability, which is suitable for various water quality. The heating tube should have uniform heat transfer and good insulation.

4. The heating pipes are arranged reasonably, and the wiring structure of the heating pipe group is detachable.

5. Each group of heating pipes can be started and shut down separately, so that the heating pipe group can be segmented and cycled to avoid large impact on the power grid when the equipment is started and operated.

6. The safety protection function in the control cabinet has the basic operation protection functions of over temperature, over pressure, overload, short circuit, leakage, water shortage and lack of equal. In the event of an abnormal situation, the unit should give an audible and visual alarm and automatically cut off the heating device until all the cuts are stopped. The control panel is a liquid crystal display.

7. The operating system is divided into manual operation and fully automatic operation, which can be switched freely.

8, the controller can be optionally equipped with 485 remote control interface, open communication protocol.

9. The electric hot water boiler adopts the separation method between the furnace body and the control cabinet, which avoids the heating of the electrical components and affects the heating. Separate electromechanical for easy wiring and maintenance.

10. The boiler body is manufactured according to the “Safety Supervision Regulations for Small and Normal Pressure Hot Water Boilers” and “General Technical Conditions for Atmospheric Pressure Hot Water Boilers”.

11. The product should be packaged and transported separately according to the boiler body, control cabinet and supporting valve.

12. The electrical components of the electric hot water boiler adopt the well-known electrical components of Zhengtai, and the power supply is 380V, 50Hz.

It can provide heating and domestic water for hotels, schools, bathrooms and other enterprises and institutions.
