LABORATORY BOX FURNACES 1200°C (2192°F)


The most reliable and widely used lab furnaces available today, the CM 1200 Series, Laboratory Box Furnaces offer controlled heating and cooling rates, temperature control, compactness, and sturdy construction for long term use. Configurations are available for virtually any requirement with three basic configurations including front loading, bottom loading and front loading atmosphere retort. Thermal cycling systems, as well as custom designs and specialized control systems are offered.

The 1200 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 double wall shell construction allows the fan cooling feature to maintain reduced skin temperatures while keeping the element terminals cool. The heating elements consist 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. Four-sided heating is offered to ensure uniform temperature control. 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 1200 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.

Sealed Atmosphere Box Furnaces for Hydrogen Environments and More

The atmosphere retort configuration includes a high quality nickel alloy retort with gas inlet and outlet ports located through the rear wall of the furnace and a water-cooled o-ring sealed front door with positive latching. Both inert and reducing atmosphere systems are offered. CM Furnaces’ time-tested hydrogen atmosphere safety package includes a gas burn-off with dual electric igniter system, process and safety gas pressure sensors, automatic switching of atmospheres and automatic shutdown with alarms. The retort system maximum use temperature is 1125°C (2060°F).
