ARIHANT plastic Heaters’ pressed in brass coil heaters deliver the benefits of the cast in brass coil heaters and eliminate known problems associated with the casting process. Originally designed for the mass spectrometry market, ARIHANT pressed in brass coil heaters have measured 8% faster responding than cast in brass heaters. The machined path in the brass for the heater enables exact repeatability of heat profile. By never exposing the coil heater to molten brass there are no risks of shifted heater coils or destruction of the thermocouple junction. Once the brass component is designed and in stock, ARIHANT pressed in brass coil heaters can be delivered in 20 business days or less. Flexible design options include internal, external “wound in” or external slotted type J or type K thermocouple. For OEM applications ARIHANT can heat profile a pressed in brass coil heater specifically to your nozzle.
