The working environment of the heating tube is generally divided into dry heating and heating liquid

●If you boil dry;

 

During dry burning, if there is a fan cycle, the power of our heating tube is generally set as: the ratio of the total length of the heating zone of the single-head heating tube electric heating tube (unit: meter) to the power of the heating tube is 1:1.5, that is The heating tube with a length of one meter, in the case of dry burning and fan circulation, the most suitable power is 1500W;

 

During dry burning, if there is no fan circulation, the power of our heating tube is generally set as: the ratio of the total length of the heating zone of the single-head heating tube electric heating tube (unit: meter) to the power of the heating tube is 1:1, that is The one-meter-long heating tube, in the case of dry burning and no fan circulation, the most suitable power is 1000W.

 

●When heating liquid;

 

When heating water or corrosive liquids, the power of the electric heating tube is set as: under normal circumstances, the ratio of the total length of the heating area of ​​the electric heating tube (unit: meter) to the power of the electric heating tube is 1:2, that is, the length of one meter Electric heating tube, the power is suitable for 2000W, of course, in the case of boiling water, the maximum can be 4000W, but the lower the power per meter, the longer the life; when heating oil, the power of the electric heating tube is set as: the heating area of ​​the electric heating tube The maximum ratio of the total length (unit: meter) to the power of the electric heating tube is 1:2.5, that is, the electric heating tube with a length of one meter has a power of up to 2500W. For normal heating of heat transfer oil, we generally set the ratio to 1 :1 or 1:1.5 to reduce the speed of carbon formation and life.

 

In general, regardless of whether the heating air is dry or the liquid is heated, the lower the power per meter, the longer the life of the heating tube!
