Multicell Heaters
The Multicell Heaters from Watlow Industries, offers extreme high process temperature capability. Independent heating zones permit application temperature gradients. Loose-fit design, for easy insertion and removal, heats platens via radiance.
| Sheath Material | Maximum Watt Density | Maximum Operating Temperature |
| Inconel® | 60 W/in² 9.3 W/cm²) | 2300 °F (1260 °C) |
Applications:
- Super Plastic Forming & Diffusion Bonding (of high performance metals)
- Hot Forging Dies
- Platen Assemblies
- Furnaces & Ovens
- Super Heating Air, Gases & Vapors
- Fluidized Beds (for heat treating)
- Glass Forming & Processing Machinery
Multicell Insertion
The advanced design of the Multicell Insertion heater from Watlow offers three major advantages: extreme process temperature capability, independent zone control for precise temperature uniformity, and loose fit design for easy insertion and removal.
Performance Capabilities:
- Engineered to Achieve Process Temperatures up to 2150 °F
- Up to Six Independently Controllable Zones
Features:
- Multiple, independently controllable zones allow process temperature uniformity not possible with any other single sheathed heater.
- The oxidized sheath provides high emissivity and improves the heaters performance as oxidation increases.
- Individually metal-sheathed coils are swaged into a larger, high temperature alloy outer sheath for maximum protection against element burnout through the outer sheath.
- The heaters radiant design allows for loose insertion in boiling holes, and piping holes. Since it will not bind or seize in the hole, the heater is easily removed and replaced with minimal down time.
- Satisfies long heater needs, 40 foot plus, providing reduced wiring.
- Quick disconnect plug and jack permit fast replacement of individual elements while the press stays at operating temperature.
- Special bending capabilities solve unusual machinery needs and keep leads away from heated zones.
Industrial Multicell
A streamlined version of Watlow's multicell insertion heater is now available for applications that do not require extreme high temperatures.
The new product, the Industrial Multicell, will operate efficiently at temperatures up to 1830 °F (1000 °C). It is designed to handle industrial applications that demand high voltages and wattages. The heaters rugged construction permits it to survive in conditions that would be lethal to many heater types.
The first heater offers up to three separate and independently controlled zones, the Industrial Multicell is designed for single zone applications, and is available in lengths from 8 inches to 18 feet.
The new heater is available in all three standard multicell diameters: 0.485, 0.685 and 0.935 inches. This product can satisfy 480 V ~(ac) three-phase power requirements for the process industry.
Performance Capabilities
- Operating Temperatures up to 1830 °F (1000 °C)
- Single Zone
Features:
- Loose fit design permits easy installation and replacement.
- Rugged construction results in longer heater life.
- Single zone heating for lower cost than multiple zone heating.
