For Sale - SRP - 2442 - Coil Heaters Cast in Brass

We manufacture coil heater cast in brass having an outer casing of stainless steel tube. Available with an added feature of built in thermocouple, its applications are similar to coil heaters, such as hot runner nozzles, pressure die cast nozzles, tube extrusion etc. but have some advantages over the coil heaters.

Advantages
- Highly non corrosive.
- Maximum heat transfer due to more contact area.
- Even temperature profile.
- Precision fit on Hot Runner Nozzles.
- Higher watt density.
- SS casing acts as a heat insulator.
- Robust cast body can withstand pressure during leakages & avoids de-coiling.

As these heaters have very specific applications they are made as per customer's requirement.
Inner diameter of these heaters is ground finished and can be provided with a tolerance of 0.02mm.

Minimum Wall Thickness
- Units without Thermocouples: 4mm
