Hazardous waste treatment systems

Features & Benefits:

Features	Benefits
Multiple, independently controllable zones	Allows process temperature uniformity not possible with any other single-sheathed heater
Radiant design of heater	Allows for loose insertion in boiling holes and piping holes Permits easy removal and replacement with minimal down time since it will not bind or seize in the hole
Oxidized sheath	Provides high emissivity and improves the heater’s performance as oxidation increases
Individually metal-sheathed coils swaged into a larger, high-temperature alloy outer sheath	Provides maximum protection against element burnout through the outer sheath
Quick disconnect plug and jack	Permits fast replacement of individual elements while the press stays at operating temperature
Special bending capabilities	Solves unusual machinery needs and keeps leads away from heated zones
Flexible leads up to 842°F (450°C)	Protects termination from high-temperature environment
