Fluid heater is a popular international high-quality long-life electric heating equipment. For the flow of liquid, gaseous medium, heating, insulation, heating. When the heating medium under pressure by electric heater chamber, using fluid thermodynamics take tremendous heat evenly heating element arising from work, so that the heating medium temperature reaches a user process requirements. Works cycle electric heater is a wasting energy is converted to heat, to heat the material to be heated. High-temperature heat energy in the working fluid medium through a pipe into the low temperature under pressure input port, along a specific change electric heating vessel internal hot runner, the fluid path using the design principles of thermodynamics, work away electric components generated, so that the heating medium temperature, electric heater outlet temperature medium to get the technical requirements. Internal control system according to the electric heater outlet temperature sensor signal to automatically adjust the output power of the electric heater, the temperature of the medium uniform output port; when the heating element over-temperature, independent of the heating element overtemperature protection device immediately cut off the heating power, to avoid over-temperature caused by heating the material coking, deterioration, carbonation, leading to serious burn heating element, effectively extending the life of the electric heater. Applications cycle electric heater Typical applications are: 1, the chemical industry, chemical materials warming heated under pressure some powder dry, chemical process, and spray drying. 2, hydrocarbons heating, including crude oil, heavy oil, fuel oil, oil, oil, paraffin, etc. 3, process water, superheated steam, molten salts, nitrogen (air) gas, water gas category, and so need to heat up the heating fluid heating. 4, due to the use of advanced explosion-proof structure, the device can be widely used in chemical, military, oil and gas, offshore platforms, ships, mining and other places need proof.
