CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The assembly typically uses nickel-chromium alloy (NiCr 80/20) for the resistance wire, ceramic insulation, a stainless steel housing (SS304 to SS316), and copper electrical connectors. These materials are selected for their electrical properties, corrosion resistance, and food safety compliance.
Rated power ranges from 3 to 12 kW, supply voltage is 220–480 V AC (three-phase, per IEC 60038), and frequency is 50 or 60 Hz. Insulation resistance is at least 100 MΩ at 500 V DC, and dielectric strength is 1500–2500 V AC for one minute, both per IEC 60335-1.
Temperature is controlled by integrated thermostats or external control systems that regulate the electrical current to the heating elements. The assembly can maintain temperature accuracy of ±1 to ±2 °C, depending on the control system and application.
The maximum continuous operating temperature is 200–350 °C. The actual limit depends on the specific model and materials used; always verify with the manufacturer for your application.
