HIGH TEMPERATURE MUFFLE FURNACE (1500⁰ C-1800⁰ C)

These models have continuous operating temperatures of 1400°C and 1800°C. These furnaces are made using advanced refractory interior, used in combination with energy efficient low thermal mass insulation and molybdenum disilicide elements, which radiate heat directly onto the workpiece
The swivel type door opens outwards keeping the hot face insulation away from the operator. The furnace door entrance is made from wear resistant Alumina bricks to enhance performance. The use of double skin construction allows natural air convection to maintain a cool outer case for maximum operating safety and comfort at highest temperatures of operation.
These units are fired using specially developed power supplies to take care of varying resistance of molybdenum disilicide elements with time and temperature of operation. Over temperature pro-tection is fitted as standard.
Over-temperature protection: This option is recommended to protect valuable contents & for unattended operation.
Data logging and remote controlled controllers: A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232 and RS485.

• Metal Retorts – A variety of metal retorts are available for use with this range of furnaces. This type of retort is generally used to cater for the following process conditions: a. To maintain controlled atmospheres within the heated chamber; b. To protect the heating elements and insulation from chemical attack by aggressive volatiles given off by fluxes, acids, etc.
• Four Sided Heating – This option upgrades the standard two sided heating to four sided heating and is recommended in the following circumstances: For use with metal retorts and ceramic liners; To improve chamber temperature uniformity to meet specific process requirements; To up rate the furnace power to cope with large lo.
• Gas Purging – This option upgrades the standard of furnace
• Thermocouple – This option upgrades the standard of thermocouple
• Over Temperature – This option is recommended to protect valuable contents & for unattended operation.
• Data Logging & Remote Controllers – A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232 and RS485.
