Immersion electrical heater:

An immersion electrical heater is a mechanism that heats a variety of fluid types — including water, oil, solvents, salts, plating baths and acids — used in industrial applications. Immersion heaters come in three varieties — over the side, flanged, and screw plug — and are installed in a tank or other vessel. With the heating element immersed in the fluid it’s warming, all of the heat is generated within the liquid and the immersion heater becomes almost 100 percent energy efficient.

The three major types of tank heaters include flanged, over-the-side, and screw plug. Flanged heaters are bolted to their container, and are the most permanent form of immersion water heater. Over-the-side heaters are named for the fact that they dangle over the side of the tank, which makes them more easily repositioned and removed. Screw plug heaters are plugged into the side of a tank, and are used for larger volumes of liquid. Both over-the-side and screw plug heaters come in many different designs, and they are also frequently used to heat liquids other than water.

Type: Flanged, over-the-side, and screw plug

Common voltage: 200V-220V-380V

Power: depend on sizes, 3KW-4.5KW-6KW-8KW-9KW-10KW-12KW-15KW-18KW-21KW, ect

Construction: Composed of 3, 6, or 9 U type tubular heater and flange, welding method: TIG argon arc

Advantage:

1. Small volume, high power

2. Can be used in any cases to heating all kinds of material, such as explosion-proof occasions

3. Heating temperature could reach 700°C

4. Heating system could be controlled automaticly, including controlling the heater by DCS system

5. Long lifetime, and with multiple protection system, safe to use

Installation Recommendations

• Select the heater size best suited for your application.
• Choose the appropriate watt density for the solution.
• Choose the proper sheath for the solution being heated to avoid corrosion.
• Uniform heat distribution in larger tanks is enhanced by the use of several heaters rather than one large heater.
• Protect heaters and tank against liquid level drops with safety controls.
• Clean heaters periodically to avoid premature failure.
• Avoid physical damage to heaters.
• Mount all heaters securely.
• Use the appropriate terminal box for each application.
• Select an appropriate temperature control.
• Electrical wiring should be in accordance with national and local codes.
• Contact us for any sales or service questions or problems.
