Application:
The low watt density cartridges are designed to heat solids by conduction. They are usually used in press mould heating or thermo-welding machines.
Maximum operating temperature of low watt density cartridge 500°C, maximum load 6W/cm² (35W/Sq. Inch) for TI with stainless steel tube and 350°C, maximum load 4W/cm² (26W/Sq. Inch) for LI with brass tube.
Technical specifications:
- Resistive alloy wire nickel chromium 80/20 coiled
- Insulation by ceramic parts
- Stainless steel tube diameter 9.5 (3/8ʺ), 10, 11, 12, 12.5, 12.7 (1/2ʺ), 13, 14, 15, 15.8 (5/8ʺ), 16, 17, 18, 19.8,20, 23, 25, 25.4 (1ʺ), 28, 30, 32, 38, 40mm.
- Tolerances on tube diameter ±0.1 mm for stainless steel
- Length from 40 to 3000 mm
- Termination by nickel cable glass fibre insulated, length to order
- Voltage up to 440 V 1 phase
- Power from 75 to 5000W
- End plug crimped
Possible variations:
- Other diameters, square cartridge
- Sheath in brass
- Water proof and plug argon welded or silver brazed
- Built in thermocouple type K or J
- Welded threaded gland BSP or metric
- Welded Flange or bracket for fixing
- Earth connection cable added
- Special sealing, e.g. high temperature cement, epoxy resin, silicon
- Connection by high temperature cable, Kapton insulated up to 400°C and ceramic beads up to 800°C
Assembly:
The low watt density cartridge should be assembled in a reamed hole with a clearance of 0.2 mm.
You must use a temperature control device to regulate the temperature of your process.
The layout of cartridges in the part to be heated must be on a regular pitch. The sensor for temperature control must be fitted in the middle.
