Pressed in Brass Coil Heaters
Basic Info
Structure :
Pressed in brass coil heater, the coil heater is designed to beset in the brass sheating, can eliminate known problems associated with the casting process.
Characteristics:
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.
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)
Advbantages
Has quick heat dissipation, high insulation, greatly extend the service life of heater
Can be built with a micro, mini, flat, low profile or round coil heater.
Safety in use
Faster responding heater due to eliminated air pockets than cast in brass
Profile and heater orientation precisely repeatable
Thermocouple not exposed to molten brass temperatures – 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
