China factory supply hot water equipment and electric heating steam
boiler for restaurant and hotels
Electric heating steam boiler Safety performance
1. leakage protection: when the boiler leakage of electricity, through the leakage circuit breaker in time to cut off the power supply, to ensure personal safety.
2. Water shortage protection: when the boiler is short of water, cut off the control circuit of the heating pipe in time to prevent the dry burning damage of the heating pipe. Meanwhile, the controller issues an alarm indicating water shortage.
3. Grounding protection: when the boiler shell is energized, leakage current is introduced into the earth through grounding wire to ensure personal safety.
Protective earthing wire should be between the earth and usually make good metal connection, often done deep Angle iron, steel pipes buried in the ground earthing body, grounding resistance shall not be greater than 4 Ω.
4. Steam overpressure protection: when the boiler steam pressure exceeds the set upper limit, the safety valve starts to release steam to reduce the pressure.
5. overcurrent protection: when the boiler overload (high voltage) work, leakage circuit breaker automatically disconnect.
6. power protection: with the help of advanced electronic circuit detection of over voltage, under voltage, break equal fault state, reliable power failure protection.
Product features
1. PLC based electric hot water boiler controller is adopted, and
LCD screen display with backlight lamp is built in, so that the
operation status of the boiler can be clearly seen.
Boiler controller display function, control function is very
complete.
All operations can be easily done by pressing a button.
2. When the electric heating pipe of the hot water boiler is
ceramic material, the electric heating mode of "water and
electricity separation" is adopted to completely separate the
electric heating pipe and furnace water to ensure the safe
operation of the boiler and facilitate maintenance and replacement
of the heating pipe.
3. When the electric heating pipe of the hot water boiler is made
of stainless steel, the "immersion" electric heating method is
adopted to make the heating water of the furnace heat up quickly
and efficiently. At the same time, the heating pipe is connected
with the flange of the furnace body, which is easy to be cleaned
and dismantled.
4. the user can be arbitrarily set between 30 ℃ -- 90 ℃ water, hot
water boiler can be according to the requirements of users, timing
and constant temperature heating to the heating circulation system
or to provide users with industrial water.
5. High-power hot water boiler adopts stepping and time-sharing
input mode to control the heating group.
The heating group can be randomly put into or stop working
according to the change of load, which obviously reduces the impact
on the power grid.
At the same time, the number of heating sections can be started or
stopped manually, which is more convenient for users to adjust the
electric power of the boiler.
