The 1000K models have a maximum continuous operating temperature of 1200°C (2192°F) and utilize half round heating elements on either side of the process tube consisting of A1 wire embedded in ceramic plate heaters. The elements are kept independent of the furnace insulation for more efficient operation and much longer life than vacuum formed element/insulation combinations. The A1 alloy in these elements is very durable at high temperatures, due to the formation of a protective oxide layer formed by reaction with the oxygen in air. The 1000K Series Control and Power Supply console includes all components required for immediate installation and operation. Proper control of A1 plate heaters requires a zero-crossover SSR, firing indicating light, circuit breaker and a multiple segment programmable control such as Honeywell or Eurotherm used in conjunction with a Type “N” thermocouple.
The 1000SC models have a maximum continuous operating temperature of 1550°C (2822°F) and utilize silicon carbide “glow bar” elements on either side of the process tube. These elements are easily replaceable through the sides of the furnace. The 1000SC Series Control and Power Supply console includes all components required for immediate installation and operation. Proper control of silicon carbide elements requires a step-down transformer, phase angle-fire SCR, ammeter and voltmeter, independent overtemperature instrumentation, circuit breaker and a multiple segment programmable control such as Honeywell or Eurotherm used in conjunction with Type “S” thermocouples.
