Description
Attached pictures show the spiral immersion heater element,this type heater is bent to spiral shape ,several rounds.So this design can shorten the heating element length and enlarge the heating area to make the best heat efficient.So it is small and easy for using ,improving the customers' heating effienct,in can also be customized,adding more round coils.
The flange is square shape as the pictures showed which is for assemble,it can also be round.
The common tube diameter is φ6.5,8.0,10.0,11.0,12.0.The machining length is 100MM-5000MM.The tube material can be stainless steel or copper or titanium.
The spiral immersion heater element is usually used in the instant water as it is small and convenient.It is electrical heating elements with two head. Protected with a stainless steel sheath. Mostly double head heater is used for heating up solids such as injection presses heating plates or various tools, double head heater can also be used for heating up water of gases under certain conditions.The choice of technology will depend on technical specifications required and the application.
When you don't know exactly which product you are looking for, we will recommend you the best solution for your needs.Tubular heaters are custom designed in a various shapes to as client's requirements for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases.

How Does an Electric Heating Element Work?
A heating element is what heats the water in your electric water heater. Metal coils extend into the heater, and the electricity that runs through these coils heats the surrounding water.
Water enters your heater through a tube at the bottom of the tank. This water, while initially cold, will be heated by the element. All electric water heaters have at least one element positioned at the bottom of the tank to ensure all of the water is heated.
The default temperature of a heating element is typically set to 120 degrees Fahrenheit. You can still change this manually via the thermostat attached to the element if you prefer a different temperature.
