New Explosion-Proof Electric Heater 380V 20kW Application Places - Yangzhou Darui
Darui Electric recommends for you
1. Heating and raising temperature of chemical materials in the chemical industry, drying of some powders under certain pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air) gas, water gas, and other fluids that need to be heated.
4. Due to the advanced explosion-proof structure, the equipment can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion-proof measures.
New Explosion-Proof Electric Heater 380V 20kW Features:
The electric heater consists of a heating core and a sheath. The heating core uses a metal tubular electric heating element as the heat source, and the sheath is made of cold-drawn seamless steel pipe or stainless steel pipe.
The electric heater is connected to the oil tank body by flange. The sheath isolates the heating core from the heated oil. When replacing the electric heater, it is not necessary to drain the oil from the tank; only need to pull out the heating core and replace it with a new one, making maintenance convenient.
The electric heater has a large contact area with the heated oil, low surface thermal power, no carbon deposition, and the oil will not carbonize due to local high temperature. Long service life, safe and reliable.

Process:
The heating tube is made by inserting electric heating wire into an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, then shrinking the tube, undergoing heat treatment (some tubes do not require it), and then processing into various shapes required by the user. It has simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids, acids, alkalis, and salts, and is also suitable for heating and melting low melting point metals.
Installation form:
Based on the design concept of high efficiency, energy saving, convenience, and practicality, we combine the actual usage of users: large storage tank volume but small oil extraction quantity at a time, and the non-continuous and irregular nature of operations. Therefore, when heating, it is not necessary to heat the entire storage tank. While saving electricity, it can also heat quickly. Local or partial heating method can be used to heat part or local media: the design concept of heating on demand, not heating when not in use. Referring to industry and standard design specifications, combined with our company's many years of practical production experience, we design instant-heating pump-out electric heaters.
