There are many reasoned explanations why industrial heaters could be installed. Besides their basic function of heating up a room or for instance every other area in the building, they can be utilized for heating material containers and for conduction of heat current. Plus, they are very helpful for bending equipments (of course, via heating) in order to leave them with the desired proportions necessary to fulfill operational needs. These units are available in several forms. You can either avail ceramic fiber heaters for transmitting radiant heat otherwise those which could heat through conductivity. Then there are the space heaters which could heat a specific area. Or else, you can even settle for (the one which we are concerned with, at present) – the cartridge heaters. These are the units which are positioned in already heated substances.
What’re Cartridge heaters?
The high watt and low watt cartridge heaters feature a resistance wire placed inside a straight and unbending tube. Often thermocouples are put inside these heating units-especially in those Cartridge heater designed for internal heating. This is completed carefully in order to render the control on the melt of the temperature. Please remember that you ought to put the thermocouple near the end of the cartridge.
If you are using the unit for external heating you should put it at where it is capable of measuring the temperature of the steel nearby the flow channel and not nearby the heater.
How they work
For internal heating the cartridge is inserted touching the melt within the channel. The length and diameter of the cartridge thus chosen are considerably governed by the dimensions of the nozzle. The cartridge heaters are duly designed in order to endure experience of plastic.
If you are aiming for heated manifolds with indirectly heated nozzles or drops you have to pop the cartridge in through the drilled holes on the sides of the runners. There should be a distance of about a size between the runner and the cartridge. It is vital for the drilled hole to comply with the diameter of the heating unit. Or else, there are serious odds of overheating.
That which you should be careful of..
Please understand that purchasing cartridge heaters is an important decision and must certanly be implemented only when you have conducted substantial research on the back ground of the dealers and manufacturers of cartridge heaters.
