Vacuum Drying Oven

      Vacuum ovens are used for drying laboratory samples in vacuum and are used up to  a maximum operating temperature of 300° C using tubular heaters and up to a maximum vacuum level of 1 mm of Hg. Vacuum ovens have stainless steel inner chambers and mild steel outer chambers duly powder coated for superior finish. The door is sealed using a silicone rubber gasket for vacuum tightness. The temperature is controlled using an automatic programmable PID Controller and a temperature sensor.

The standard sizes available are:

I)                    450 (W) x 450 (H) x 450 (D)

II)                  300 (W) x 300 (H) x 300 (D)

III)                 300 (W) x 300 (H) x 400 (D)

  • 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
  • R-Type Thermocouple - This option upgrades the standard K Type (mineral insulated inside Inconel sheath) thermocouple to R-Type thermocouple and is recommended if furnace is going to be used continuously at 1200 C.
  • 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.
