Press In Brass Coil Heater With Cross Section 4.2x2.2mm With Inbuilt Thermocouple
1. Introduction
Pressed in Brass Coil Heater are suitable for eliminating known problems that are associated with the casting process in spectrometry industries.
Our range is capable of functioning 8% faster than cast in brass heaters. The component integrated in the brass for the heater enables in facilitating exact repeatability of heat profile.
Furthermore, even when the coil heaters are exposed with molten brass, there would be no destruction of the thermocouple junction.
Our products are available in flexible designs like internal, external “wound in” or external slotted type J or type K thermocouple.
2. Characteristics
1). Optimal heat distribution
2). Tight fit on nozzle
3). Superior heat transfer
4). Up to 1200°F at inner brass casing
5). Highly non-corrosive
6). Built-in Type J or Type K thermocouple

4. Application
Hot runner heater is the important component of hot runner system, which is made of special technque and high quality material, ensuring its efficient work in the close space, even when the heating jacket temperature is 700 degrees Celsius. Complying with the metric system and the international standard, all models are on the basis of VDE0721 quality inspection requirements, so as to meet most factories and hot runner machines.
we provide several kinds of heaters, such as pipe heater, press in brass heater, coil heater and so on.
