Heaters' elements are PTC positive temperature coefficient semiconductors - making the heaters self-limiting. That is, they reach a set maximum sheath temperature (which is below the ignition point of most combustible materials), meaning they are especially safe for process applications.

• PTC heater element lasts longer than conventional heaters
• Will not burn out if run in air
• Will not burn out due to scale or sludge buildup

• Heater self limits its maximum operating temperature to 250°C (below ignition point of most plastics)
• Will not melt tanks when a 1/2" (12mm) minimum distance is maintained
• Overtemperature protection devices are not required
• Safety is built-in, not added on
• Metal-grounded construction (earth ground)
• Non-floating construction

Sizes: 1,000 watts (1kW) to 6,000 watts (6kW)

Voltages: Three voltage ranges available: 110-120 volt, 200-240 volt, and 380-480 volt. Heater is available in single or three phase power.

Corrosion resistant heads: Vapor-resistant, flame retardant polypropylene terminal enclosures each with 3-foot (.9m) flexible PVC liquid tight conduits.

• Watt densities of 4 watts/cm² ensure long service life
• Auto-stabilizing solid state element prevents hot spots and ensures uniform heating
• Heater derates itself in highly viscous and high temperature solutions

Consult factory for sizing assistance
