Why do some machines work for many years without element failure?
It’s the finer details of the unitemp ceramic bandheater that make the difference!
For example, the heating wire/ spiral is specially calculated and selected using a computer simulation program.
It is critical that the power rating per surface area of heating wire selected does not exceed certain values in order to ensure a “beyond satisfactory” life span of the heater.
In addition, the stainless steel outer clamp not only serves as a clamping mechanism but also must protect the fragile ceramic formers inside. Therefore, special attention is given to the side wall serration. It is serrated in such a way that it acts as a shock absorber in case of any physical damage.
Generally, electrical terminal lugs are of the tin plated copper type. Due to the high heat stresses these tend to corrode very quickly and become brittle. They are unsuitable for heating elements but tend to be used to lower the cost of a band.
At unitemp, to eliminate this problem special nickel lugs are used which can sustain high temperature and increase reliability.
For large, high-power bands unitemp uses special robust ceramic insulated connectors to ensure that no breakages occur. These are also easier to connect.
Our unique design ensures trouble-free operation and will, ultimately, reduce the maintenance and downtime on your machine.
In conclusion, the quality and lifespan does not only depend on the outside appearance of the heater, but also on the design effort and hidden detail.
Ultimately, ensuring that your heater is giving you a long and hassle-free service will reduce your downtime costs and frustrations substantially.
