Electric heater refers to the electrical appliances that use electric energy to achieve heating effect. It has small volume, high heating power and is widely used. It adopts intelligent control mode and has high temperature control precision. It can be networked with computer. It has wide application range, long service life and high reliability. The core of the heater principle of frame heater manufacturer is energy conversion, the most widely used is the conversion of electric energy into heat energy. For example, the electric heater, which uses metal to generate eddy current in alternating magnetic field to heat itself and absorb, is the conversion of electric energy into light energy; for example, solar hot water.

Bioenergy is a kind of energy stored in the form of chemical energy in the form of biological carrier, which is directly or indirectly derived from plant photosynthesis. In addition, there are energy conversion modes such as nuclear energy and wind energy, but they generally need to be converted into electricity.

Oil tanks play a very important role in the process of oil and gas storage and transportation. In oil and gas storage, oil tanks are mostly used for oil storage. When oil is needed, it is exported from the tank. In the process of oil product export, it is unavoidable to encounter such a problem. Because of the low temperature, the oil product becomes viscous, which reduces the fluidity of the oil product, resulting in the oil product can not be smoothly exported from the oil tank, so the heater of the oil tank is needed.
