Heavy‑Duty Large Capacity Autoclaves 

Giant autoclaves are used to process very large or bulky items that cannot fit into standard-sized autoclaves. They are common in industries like aerospace, automotive, and manufacturing, where big parts or large batches need to be cured or sterilized all at once.

An autoclave should generally be filled to about two-thirds or 75% of its total volume. Overfilling can block steam circulation, leading to uneven heating and incomplete sterilization or curing.

121°C (250°F) is the standard temperature used for steam sterilization because it effectively kills most bacteria, viruses, and spores in a reasonable amount of time, typically around 15 to 30 minutes.

Autoclaves come in many sizes, from small bench-top models used in labs to large walk-in or giant autoclaves used for big industrial parts. Sizes are usually measured by chamber volume and can range from a few litres to several thousand litres.

121°C cycles are usually used for general sterilization and take longer, while 134°C cycles use higher temperature steam for shorter times and are often used for more resistant bacteria or medical instruments requiring faster turnaround.

Most autoclaves operate at pressures between 15 to 30 psi (pounds per square inch). This pressure level helps raise the steam temperature above boiling, allowing for effective sterilization or curing.
