Overview

Uniform, efficient heat for ageing and conditioning

Many plastics and rubber tests require specimens to be aged, conditioned, shrunk or dried at a controlled temperature. Uniform heat across the chamber is essential for comparable results, and radial air circulation delivers it efficiently.

International Equipments builds a hot air oven with a radial fan that re-circulates hot air (saving at least 20% power), a digital presettable timer up to 999 minutes and an auto-shut facility, reaching 250 °C. Manufactured in Mumbai, CE marked and calibration-certified.

How the test works

Step by step

  1. Set temperature & timeSet the target temperature (up to 250 °C) and the digital timer.
  2. Load specimensPlace the specimens in the 12 in chamber.
  3. RunThe radial fan circulates hot air for uniform heating; the oven auto-shuts at the set time.
  4. Remove & testRemove the aged or conditioned specimens for testing.

FAQ

Frequently asked questions

What is the hot air oven used for?
Heat ageing, conditioning, shrinkage testing and drying of specimens at a controlled temperature up to 250 °C, with uniform radial-fan circulation.
How does radial circulation help?
The radial fan re-circulates the hot air inside the chamber for even temperature, and saves at least 20% power compared with single-pass heating.
What is the chamber size?
12 in × 12 in × 12 in as standard, with other capacities available on request.
Does it switch off automatically?
Yes — a digital presettable timer (up to 999 minutes) with an auto-shut facility is provided.
