Seeking help with laboratory heating issues!
Thread Content
I have a question now: how to heat the oil inside a cylindrical tank in order to control its temperature. I’m thinking of adding a heating layer, along with thermocouples and a temperature controller. Could anyone give me some advice on how to combine these elements? How to build a heating layer? What to use for heating? How to use it in conjunction with a thermocouple? Also, how to choose the insulation material and determine its thickness? Thank you so much to everyone!
Electric heating, equipped with a voltage regulator to control the heating speed, along with a K-type temperature controller
I’ve learned that the choices in the laboratory may differ from those in practice. If I had a choice, I would use an electric heating element for direct heating. Use a thermostat to control the oil temperature.
It is necessary to consider the physical properties of the oil in order to choose the heating method.
Planning to use ordinary heat transfer oil and silicone oil
For certain reasons, it is not possible to use an electric heating element for direct heating; therefore, a heating layer must be used outside to provide heat
I don’t know what is used to heat the outer heating layer right now.
For capacities up to 10L, electric heating can be considered, with temperature measurement points installed inside and outside the equipment. Heating methods that have been used include electric wire heaters and stainless steel coil heaters; the heat tracing belts used in the early days were not very effective. ------------------------------------ For larger equipment, I usually design it by adding a jacket on the outside and using thermal oil for electric heating; temperature sensors are also installed within the jacket and inside the equipment. It is not recommended to use heating elements directly inside the equipment. Or use an oil temperature controller with heat transfer oil for circulating heating/cooling. They are all designed for school laboratories~ ------------------------------------ The thickness of the insulation layer depends on the highest temperature at which it will be used; I’m not sure about the exact details:lol
How large can the equipment in a laboratory be? An electric heater is sufficient.
What kind of electric heater is it? Please provide more details
