Press in Brass Coil Heater

Press in brass coil heater, the coil heater is designed to beset in the brass 
sheating, can eliminate known problems associated with the casting process.

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.

Flexible design options include internal, external “wound in” or external 
slotted type J or type K thermocouples.

For OEM application, HT-Elite can customize the brass sheathing upon request.

Technical Parameter

Heater Sheath: CrNi Steel
High Voltage Stability: 800VAC
Insulation Resistance: >= 5M ohm at 500 VDC (Cold)
Wattage Tolerance: +/- 2%, +/- 4%, or +/-10%
Maximum Voltage: 230V
Leakage Current: <= 0.5 mA at 250VAC (Cold)

Advantage:
1. Has quick heat dissipation, high insulation, greatly extend the service life of 
heater
2. Can be built with a Micro, Mini, Flat, Low profile, or Round Nexthermal Coil 
Heater.
3. Safety in use
4. Faster responding heater due to eliminated air pockets than cast in brass
5. Profile and heater orientation precisely repeatable
6. Thermocouple not exposed to molten brass temperatures; 
7. Improved durability
Potential for designing thin walled brass heaters to minimize OD impact
Faster responding heater due to eliminated air pockets than cast in brass
