Thermetics Kappa Series are constructed with a nickel-plated copper inner sleeve and stainless outer sleeve. The heater is tightly sandwiched between these sleeves eliminating the heat transfer problems associated with other dual sleeved designs. The materials used direct the heat inward towards the nozzle, resulting in a very efficient heater with even heat distribution. The tightly tolerance ID allows a slip fit with no clamping required. Our patented method of thermal profiling produces very flat temperature profiles over the length of the nozzle.
This style consists of a brass conduction tube with grooves machined into the OD. A heater and thermocouple (as an option) are pressed into the grooves. This results in excellent thermal uniformity over the ID of the heater. Since the heater is so well heat sunk, much higher watt densities are possible. This also results in much longer heater life.
