What factors should be considered in the selection of self-controlling electric heating cables?
The selection of automatic temperature electric heating cables should not only consider the length, but also consider the following factors, namely: 1. Maintenance temperature If it is only antifreeze, usually this value is set at 5-10 degrees; if it is process heat tracing, it is necessary t...Read more -
Principle of explosion-proof electric heater
Flameproof type “d” Explosion-proof principle： An enclosure of electrical equipment that can withstand the internal explosion of a flammable mixture that has entered the enclosure without damage, and will not ignite an external explosive atmosphere formed by the same one or more gas...Read more -
Types and setting modes of reactor electric heaters
Everyone should know about the electric reactor heater, but its classification may be relatively unfamiliar. At present, the electric reactor heater can be divided into three types, each of which is aimed at different heating positions. The effects are also different. Which three are there? One i...Read more -
The difference between electric heat tracing and steam tracing
Before the 1970s, the energy industry used steam tracing to do antifreeze and heat preservation projects. Then to the early 1980s, after research and reform, steam heat tracing has been replaced by electric heat tracing. The technology has been continuously improved in practice, and it has been u...Read more -
Steps to Calculate Heater Power for Electric Heaters
According to the process, draw the process flow chart of heating (does not involve material form and specification). Calculate the heat required for the process. Calculate the amount of heat and time required to start the system. Redraw the heating process flow chart, consider the appropriate saf...Read more -
Functional characteristics of explosion-proof electric heater

The thermal response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high. 3. High heating temperature: The maximum working temperature of the heate...Read more -
Electric heater internal fault solution and heating method
The burnout of the electric heater and the short-circuit of the internal system of the heater are also common faults. Once the internal system has a short-circuit fault, if it is not eliminated in time, the internal system cannot guarantee the quality and use of the pigment products, and it will ...Read more -
Types and characteristics of control systems in electric heaters
Whether in industrial production or in scientific research experiments, electric heaters are a kind of heating and heat preservation equipment that is frequently used. In the process of processing, it is often necessary to strictly control the rise and fall of temperature. With the promotion of c...Read more -
Structural layout and working principle of flanged electric heater
Since there are various types of electric heaters, it is not easy for users to choose a suitable one, and at least have a basic understanding of a commonly used electric heater. Take the flanged electric heater as an example, do you know its structure, performance and working principle? Start wit...Read more -
Overhaul and Outer Dimensions of Heaters
The heating speed of the heater is fast and the heat transfer efficiency is high. There will be no local high temperature in the asphalt, which ensures the quality of the product. A heating sleeve is added to the inlet and outlet of the asphalt to ensure the fluidity of the asphalt. A basket filt...Read more -
Introduction to the working principle and construction of electric heat tracing and insulation of pipelines
Pipeline electric heat tracing and insulation is a new type of heating system, which can also be called a heating cable low-temperature heat tracing system. It is realized by converting electrical energy into heat energy. What is its principle? How to build it? These are all problems that we need...Read more -
