Our control system, designed for ETO sterilization equipment

RSD has developed a specific control system for industrial ethylene oxide sterilizers.
The ETO sterilization process requires a high level of safety to be optimal, safe and reliable for the personnel, the equipment, until the products that have to be sterilized.
Given the fact that the ethylene oxide gas is explosive, flammable and toxic properties, it is important to have an adequate and reliable control system.

The advantages of our control system

RSD has developed its own control system based on SCADA technology and safety PLC (the “brain” of the process).
The PLC is based on high-quality technology using Siemens/Allen Bradley brands, and SIL certified as per IEC 61508. To meet the safety requirements, the PLC and the SCADA are programmed in accordance with the HAZOP analysis and SIL definition for each project, always fulfilling the 21 CFR Part 11.

The characteristics of our SCADA:
Use of Intouch, worldwide known as a most, to develop the SCADA according to each customer’s needs and fulfilling the GAMP 5 recommendations.
  • The data of the sterilization cycles are saved in a database (including backups) and are protected by a password.
  • The system manages the whole installation interlocks.
  • Possibility to use an audit trail.
  • 6 levels of users are proposed (operator, supervisor, director, maintenance, administrator and calibration) without users’ limitation. According to the user level some actions will be available or not.
  • The whole software is validated.
  • Flexible recipes.
  • The inflammable diagram is automatically calculated for each new recipe to keep the process in the safe zone.
  • Screen availability for calibration operations.
  • Availability for manual / automatic modes to operate the process.
  • Automatically generation of final reports.
  • User friendly screens: synoptics, graphs, alarms, …
PLC characteristics:
  • PLC certified according to SIL normative (IEC 61508) and installed in the main electrical cabinet.
  • The SAFETY PLC has safe modules to control any critical inputs and outputs of the installation, and standard functions are configured for the non-critical operations
  • Well-known brands: Siemens or Allen Bradley.
Strict validation protocols are executed:
Strict quality protocols are performed, in order to ensure that the equipment and the operations are safe and reliable. Our control department takes care of the following protocols:
  • SDS (Software and Design Specifications).
  • SMDS (Software Module Design Specifications).
  • SMTS (Software Module Test Specifications).
In addition, and thanks to its huge experience and skilled personnel, our control department defines the appropriate application of every single customized project.
The risk analysis of the project is taken into account on the software application, as well as the GAMP 5 and 21 FCR part 11 aspects. In such a way, the customer is ensured to buy a safe, efficient and reliable control system.

As manufacturer of ETO sterilization solutions, we offer programming services as well as a validated control system for any ETO sterilization equipment.

Come to see us in our booth Hall 12 / A68 and find out our bespoke services for pharmaceutical and medical device industries.

The “SEC Signature DIR” sensors for EO applications are now ATEX certified

These sensors, worldwide recognized to measure both the EO concentration and the H2O, are since august 2019 available in Europe with the ATEX certification thanks to RSD company.

RSD, with the agreement of the US Company “Sensor Electronics Corporation” (SEC signature DIR sensors manufacturer) decided to take care of all the analysis and tests to obtain the ATEX certification for these sensors. RSD is from now on the official importer in Europe for the SEC Signature DIR sensors, delivering the ATEX certificate.

Features of the SEC Signature DIR sensors
This sensor also called DUAL gas analyzer has been specially designed for EO applications, see below its main characteristics:

  • Measure both of the ethylene oxide concentration and the humidity level inside the autoclaves. Two essential information in the ethylene oxide sterilization process
  • A state-of-the-art technology worldwide recognized.
  • Uses leading technologies to offer reliable and accurate results.
  • Allows the parametric release. Thanks to the measure both of eo concentration and humidity level the parametric release is possible, which enables of BI’s results, leading to a time, money and space savings.
  • Infrared sensing technology.
  • Explosion proof (Ex nA, II3G).
  • Designed for harsh environments.
  • Self-compensating optical system (patented).
  • Fast response time.
  • Virtually maintenance free.
  • An affordable price.

The SEC Signature DIR sensors, ATEX certified
The ATEX regulation, mandatory in any European countries, has the objective to control and reduce the risks regarding explosive atmospheres that can exist in facilities and equipment.

ATEX directives:
  • 2014/34/UE (former 94/9/EU): for equipment to be installed in ATEX zones
  • 1999/92/EC: for the worker safety.
In the past, these gas detectors couldn’t be used in European installations because they didn’t have the ATEX certificate. From now on, they are ATEX certified by the notified body “LOM” in Spain, and fulfil the 2014/34/UE regulation for equipment / machines that is used in potential explosive atmosphere.

A great news for any company that sterilizes products in Europe thanks to ethylene oxide process and have the need to install those sensors on their EO autoclaves.
The SEC Signature DIR detector, supplied by RSD
We supply the SEC Signature DIR sensors (from the US Company Sensor Electronics Corporation) in Europe, with the ATEX certification.

We propose:
  • The SEC Signature DIR.
  •  A wide range of options: signal converter, junction box, adapter, calibration gases and dedicated electrical cabinet.
  •  The installation and control (PLC & SCADA) of the parametric release in client’s facilities with calibration services and training.

We remain at your disposal for further information about this product, do not hesitate to contact us at and visit-us in our booth 12/A68.
