Nexthermal Hotslot pressed in brass coil heaters deliver the benefits of cast in brass coil heaters and eliminate known problems associated with the casting process.  Originally designed for the mass spectrometry market, Nexthermal Hotslot 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, Nexthermal Hotslot coil heaters can be delivered in 7 business days or less. Flexible design options include internal, external “wound in” or external slotted type J or type K thermocouple For OEM applications Nexthermal can heat profile a Hotslot coil heater specifically to your nozzle.
