Since 1995, we have been functioning as Laboratory Muffle Furnace, CORNSIL® Manufacturer, Exporter and Supplier from Pondicherry, India. Featuring wide,

We have two types of Muffle furnace, one is Electric Muffle Furnace (900 – 1100 Deg C) and another one is Electric Furnace (1200 Deg C).

Electric Muffle Furnace (900 – 1100 Deg C) :

  • Muffle Furnace construction comprises of an outer chamber fabricated out of thick cold rolled mild steel sheets.
  • Rectangular in shape placed horizontally with opening in the front.
  • Refractory muffle of required size forms the inner chamber.
  • This is surrounded by ceramic fibre blankets on all the four sides and the rear to reduce heat losses to minimum.
  • The furnace is heated by KANTHALAI heating coils wound in spiral form on the muffle embedded in high grade refractory cement and backed by ceramic fibre blankets.
  • The temperature inside is maintained at any desired level within the operating range by a digital automatic temperature Indicator –cum-controller working in conjunction with a Cr/Al thermocouple housed in the hot zone.

 

Control panel:

Consists of temperature controller, Air break magnetic contactor, indicating lamps, energy regulator.

The furnace is finished in attractive powder coat finish.

Technical Specifications:

  • Operating temp  : 900°C, 1000°C to 1100°C
  • Temp. accuracy  : 1% of set temperature
  • Power supply :  230volts AC, single phase

Optional:

Microprocessor based digital PID controller with SSR output for better accuracy of 2 to 3°C.

 

Electric Furnace (1200 Deg. C):

  • The general design and construction comprises of an outer chamber fabricated out of thick cold rolled mild steel sheets, rectangular in shape placed horizontally with opening in the front. 
  • Refractory muffle of required size forms the inner chamber. 
  • This is surrounded by ceramic fibre blankets on all the four sides and the wear to reduce heat losses to a minimum.
  • The chamber is provided with a single door with 100mm thick ceramic fibre insulation mounted on heavy duty hinges and provided with latch.
  • The furnace is heated by KANTHALAPAM heating coils would in spiral form on the muffle embedded in high grade refractory cement and backed by ceramic fibre blankets.
