Hot Air Oven Sterilizer

Hot air ovens are electrical devices which use dry heat to sterilize. They were originally developed by Pasteur. Generally, they can be operated from 50 to 300 °C, using a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy, the inner layer being a poor conductor and outer layer being metallic. There is also an air filled space in between to aid insulation. An air circulating fan helps in uniform distribution of the heat. These are fitted with the adjustable wire mesh plated trays or aluminium trays and may have an on/off rocker switch, as well as indicators and controls for temperature and holding time. The capacities of these ovens vary. Power supply needs vary from country to country, depending on the voltage and frequency (hertz) used. Temperature sensitive tapes or biological indicators using bacterial spores can be used as controls, to test for the efficacy of the device during use.

This Hot Air Oven Sterilizer is designed for general purpose in applications in variety of baking, drying, conditioning, preheating, curing for dry content analysis, chemical resistance studies, glassware drying, dry sterilizer etc.

Key Features:

  • All equipment features double wall construction for durability and good heat retention.
  • Heavy-gauge glass fiber insulation sustains to prevent the heat loss and maximize energized efficiency.
  • Timer is working only when the actual temperature arrived 2ºC below set point.
  • LED digital set and display for Power, Heating, PV, SV and Alarm.
  • Adjustable fresh air inlet port at bottom and top provides control of the amount of convective air.
  • Quality surface treated by power coating ensures scratch free and corrosion free.

Safety devices:

  • Over temperature alarm and shutout device to 10ºC above the set point.
  • Independent safety switch to shut out power protecting oven from excessive heating at 220ºC if primary control fails.
  • Optional for current leakage breaker with O.C.
  • Audible & visible alarm indicated by indicator.
  • Timer stop counting when PV is 5ºC below SV after stabilization if door is opened, the memory will store the past time and start to count when the PV value returns to 2ºC below SV.
