The CM 1300 Series Diffusion Tube Furnaces offer controlled heating and cooling rates, uniform temperature control, compactness, and sturdy construction for long term use. Both horizontal and vertical models are available for virtually any requirement in single or multi-zone configurations. Atmosphere and vacuum packages, and specialized control systems are offered in addition to the standard furnaces.
The 1300 Series furnaces incorporate a graded insulation package using high purity alumina fiber. These furnaces will not hot spot at high temperatures and are resistant to degradation. The rugged exterior consists of a perforated aluminum shell and solid end caps An internal winding consisting of heavy gauge A1 wire is wound around the circumference of the inner furnace cavity and offset from the work tube by an array of ceramic spacers. 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 1300 Series Control and Power Supply console includes all components required for immediate installation and operation. Proper control of the element winding requires a step-down transformer, phase angle-fire SCR, ammeter and voltmeter, circuit breaker and a multiple segment programmable control such as Honeywell or Eurotherm used in conjunction with a Type “S” thermocouple.
