Hot air sterilizers

Air is certainly the least expensive means of exchanging heat with the medical devices to be sterilized. Hot air is the classic method for sterilizing materials that would be damaged by steam, such as sharp instruments and glassware.

C.B.M. combines tradition with the latest technologies and the hygiene of stainless steel.

The “Panacea” dry heat sterilizers, absolutely recognizable for their “stainless” design, guarantee the best sterilization performance thanks to a microprocessor control equipped with a P.I.D. system.

C.B.M. offers hot air sterilizers for every need, from the hospital to the professional's office.

P.I.D. is an acronym of the following words:

• P = Proportional
• I = Integral
• D = Derivative

This acronym identifies the calculation algorithm used by the system to check that the reference temperature is correctly reached.

In our sterilizers this algorithm is applied to the temperature control system to achieve the correct sterilization conditions.

The PID algorithm compares the real temperature inside the chamber and the reference temperature, after which it calculates the difference between them and regulates the heating in order to reach the final temperature avoiding oscillations around the reference point.

In particular, the system is made up of three different variables:

• The proportional variable increases the speed at which the reference temperature is reached
• The derivative variable regulates the system close to the sterilization temperature in order to avoid oscillations
• The integral variable ensures that the system reaches the exact reference value
