Cast in Aluminum/Bronze Alloy Nozzle Heaters:
Pressed in Brass Coil Heater
Cast In Brass Alloy Nozzle Heaters
National Plastic Heaters' 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, NPH 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, NPH pressed in brass 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 NPH can heat profile a pressed in brass coil heater specifically to your
nozzle.
