System description and eight characteristics of electric heater

The electric heater operation, in our opinion is very strange, although there have been previous knowledge of foreshadowing, but it is a type of electric heater, compared with ordinary electric heater, or different, so we should seriously learn about, and to be able to learn to use, in order to better use of it.

A system description of an electric heater

The electric heater is using resistive heating, its appearance, is a flange type electric heater.

The electric heater should be installed horizontally and supported by legs. The temperature control is realized through the temperature control table, which can control the output power of the heater and achieve stepless power regulation.

Its temperature alarm can detect the temperature inside the heater in order to prevent the heating inside the heater and damage the heater. When the temperature in the heater exceeds the specified value, the alarm indicator light is lit, and it is automatically locked. The heater can be restarted by artificial reset.

The system also has a pressure alarm chain system. When the pressure of the medium is normal, the heater can be started. Otherwise, it can not start.

When the electric heater is running, it can be automatically cut off and then alarm when the internal flow is over or the phase is missing.

The system can have multiple chains and can be used in chain with other devices, but if it is not used, a short connection is needed.

Distribution plate operation of electric heater

Check all the lines and ensure that the connection is reliable.

The chain points should be in accordance with the requirements, and the urgent stop buttons on the panel should be in normal use.

The electric heater has a chain pressure alarm. When the alarm is broken, the contact is broken, and the heater is turned off. After that, the electric heater can start automatically.

The starting and stopping of the heater can be operated at the same time at the same time.

If the heater is not used, the main circuit breaker should be disconnected to prevent the failure.

Electric heaters have the following characteristics:

The heating temperature is high: the heater can be designed for the highest working temperature of 850 degrees C.

The temperature of the medium is uniform and the precision of temperature control is high.

Wide application and strong adaptability: the heater can be applied to explosion-proof or ordinary occasions, explosion-proof grade can reach D II B grade and C grade, and the pressure can be up to 20MPa.

Small volume and high power: the heater mainly uses a cluster tubular electric heating element.

The heat response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high.

As a professional electric heater manufacturer, our electric heater has long service life and high reliability: the heater is made of special electrothermal material, and its surface power load is low, and multiple protection is adopted, so that the safety and life of electric heater will be greatly increased.

The energy saving effect shows that almost 100% of the energy generated by electric energy is transmitted to the heating medium.

Fully automatic control: according to the requirement, through heater circuit design, it can realize automatic control of outlet temperature, flow and pressure and so on, and it can be networked with computer.
