Band heaters and industrial heaters are ring-shaped heating devices that are usually clamped around the cylindrical element to help in heating. The heat will transfer from these heaters through a conductive method. Here is a guide on band heaters and industrial heaters for sale and factors to consider before purchasing them.
Selecting band heaters and industrial heaters requires that you analyze their performance specifications and the features they have. Some of the parameters that you need to consider when going to shop for them include their maximum operating or sheath temperature, watts, and AC voltage required to heat them.
The most important dimension you need to consider when looking for these heaters includes the bands inside diameter and thickness. As a rule, the cylinder to be heated needs to have the same diameter as the inside part of the heater.
The heater uses a sleeve or sheath for the outside cover protection of the heating elements. There are several types of materials one can choose for their sleeve. They include aluminum, copper, steel, brass nickel alloy, iron, and stainless steel.
Typically, insulation is used to control the amount of heat lost to the environment during the heating process. The different choices of insulation you can find include no insulation, mica insulation, fiberglass insulation, ceramic insulation, and mineral insulation. You will find so many products that have more than one type of insulation. For example, heaters that are equipped with ceramic insulation can resist both chemicals and heat. Those insulated using mica are believed to offer high resistance to acids and heat. However, those that are not insulated are not energy efficient.
Termination type, in this case, means the various methods you can use to make the electrical connection to your heater. Some heaters have several options for the termination type, which includes: insulated leads, metal braided leads, parallel screw terminals, quick disconnects, armor cable leads, terminal boxes, flexible conduit leads, and tandem screw terminals.
The feature options that you need to look out for are the various cooling options they have, insulated shrouds, probe holes or cutouts on the band, and expandable heaters.
It is important that the heater chooses to be attached or clamped well to the objects you will be heating. The good thing is that most heaters that you will find in the market have different clamping options that you can select. Examples of the options you will find include: built-in strap, barrel nuts, quick release, flange or tab, separate straps, and wedge lock or mounts.
Finally, it is important that you consider all your needs carefully and the kind of heating you will be carrying out before choosing a heater. Ensure that you use the guideline above to select the best heater that will provide you with the needed heating functions and features that are effective, good results, cost services, and easy to manage and maintain. You can also ask for help if you are not so sure of what you want.
