Non-swaged cartridge heaters offer a cost effective solution where the performance of a swaged heater is not required. Non-swaged heaters can be used at watt densities up to 45 watts per square inch and temperatures up to 1000°F. Non-swaged heaters offer tighter length tolerances than swaged heaters. Non-swaged heaters can be built with 3 independent heat zones. Non-swaged heaters are not recommended for applications where there is a lot of vibration or impact.
Construction
