Are all Preconditioning Cells Equal?

20 years experience dealing with Preconditioning Cells

Preconditioning of the product load is performed to get optimum temperature and humidity into the product before injection of Ethylene Oxide. Typically these conditions are achieved in an in line preconditioning cell.

We have installed many preconditioning cell over the past 20 years and upgraded and modified many more. We like to think that our experience over this time make our cells one of the best available.


About Preconditioning Cells

Airflow is key Typically preconditioning cells are fabricated from insulated panels forming a cell with internal dimensions identical or close to the sterilisation chamber dimensions. From the outside most cells look similar but often vary greatly in performance. This can be down to a number of factors that aren't obvious from the outside. Without giving too much away our cells have been developed of two decades create a tight boundary flow across the all surfaces within the load with a close temperature and humidity tolerance.
High Quality Insulation Combined with high quality insulation our cells offer optimum preconditioning performance Tight control of humidity stops condense within the cell and together with the robust cell structure this ensures a long life.
Flow v's energy the optimum balance Having had the opportunity in the past to test various air change options we have optimized the cell to ensure the highest return for energy input.
Would Vacuum Preconditioning Work? Yes the same shallow vacuum technology would most certainly speed up the product load reaching temperature and humidity. For the time being however most users do not have a time problem in preconditioning. If you have a different experience with preconditioning being a bottleneck we would be very interested in applying our vacuum technology to your application.
Compliance The preconditioning cell process has been assessed to identify any EU Directives, regulations and standards. The preconditioning cell was then designed, assessed and tested against the identified directives
  • EN ISO 12100: Safety of Machinery - General Principles for Design - Risk Assessment and Risk Reduction
  • EN ISO 13849-1: Safety of Machinery - Safety-related Parts of Control Systems - Part 1: General Principles for Design
  • EN 60204-1: Safety Of Machinery - Electrical Equipment Of Machines - Part 1: General Requirements
