RSD is a European company that manufactures and develops industrial sterilisation solutions for medical device and pharmaceutical companies.

The company specialises in manufacturing ethylene oxide (EO) sterilisers and offers turnkey EO equipment sterilisation and ancillary equipment.

RSD’s turnkey solutions are efficient and innovative sterilisation facilities that use advanced technology and comply with the safety levels and regulatory requirements of the medical industries.

Ethylene oxide sterilisation equipment and turnkey solutions

RSD utilises its experience of the EO sterilisation process to provide high-quality sterilisation services and customisable equipment. It adapts these solutions to meet client specifications and provides project support throughout projects, from initial phases to completion.

The company’s portfolio includes EO sterilisers, steam generators, EO detection systems, and automatic loading and unloading systems. These can be selected individually or combined as part of a turnkey EO sterilisation project. A wide range of options and configurations are available.

RSD manages all project phases, including design, development, manufacturing, control, commissioning and validation.

High-efficiency customisable EO steriliser and autoclave design and manufacturing

RSD’s modular industrial sterilisers have a flexible design to help divide high-risk processes and reduce the probability of developing an explosive atmosphere during EO sterilisation.

They also maintain a uniform EO concentration and temperature, have high levels of safety (ATEX certified for zone1 and zone2) and are optimised for energy consumption and cycle time.

The systems include gas rooms, vapouriser skids, vacuum pump skids and control room as standard. They also have further options for parametrical release, automatic loading and unloading systems, preconditioning and degassing cells, steam generators, catalytic systems or scrubbers and EO detectors.

They are also customisable and use both 100% EO (+N2) and a 90/100 mixture to limit the chamber’s internal pressure (<+0,5b).

RSD’s EO sterilisation chambers can work all-in-one or with additional preconditioning and degassing cells.

EO sterilisation equipment safety

RSD’s units are rigorously tested to ensure a high level of safety for both the equipment and its operators.

The sterilisers also use a programmable logic controller (PLC) comprising special safety modules that are programmed together with a supervisory control and data acquisition (SCADA) unit, according to Hazard and Operational Stability study (HAZOP).

In addition, safety integrity level 2 (SIL2) is applied to instrumentation, steriliser components and the PLC.

Qualification of sterilisation equipment

RSD conducts a wide range of validation and qualification tests to optimise sterilisation equipment operations to avoid risk. Stringent protocols are used, including:

  • Design qualification (DQ), including functional design qualification (FDS), safety data sheets (SDS), safety monitoring device and system (SMDS)
  • Factory acceptance tests (FAT) and site acceptance tests (SAT)
  • Installation qualification (IQ) and operational qualification (OQ)
  • Support for performance qualification (PQ)

The sterilisers and ancillary equipment are CE certified and comply with European standards and directives. Training for operators and maintenance staff is included in RSD’s turnkey projects.

Pharmaceutical engineering for industrial equipment

As experts in industrial sterilisation, RSD provides engineering services for sterilisation equipment such as pure steam, superheated water, air+steam sterilisation systems and other pharmaceutical equipment.

The company handles layout, 3D design and constructive drawings; quality control and project management aspects. Its specialists are Ism-ATEX certificated level 1 and 2 for design and maintenance of both electrical and mechanical systems.

Consultancy services for EO sterilisation process

RSD offers consulting services for EO cycle optimisation and validation, maintenance of autoclave sterilisation and plants, installation and verification. They also provide consultancy solutions for qualification protocols and tests, plant scale-up, utility calculations, safety audits according to the ATEX 2014/34/UE directive, installation upgrades and parametric release implantation.

EO Sterilisation Equipment by RSD

The EO sterilisation technology is developed for medical device manufacturers and the pharmaceutical industry. Innovation, advanced technology and safety are present in RSD's equipment. The company provides custom and turnkey solutions where all anci

ETO Sterilisers Brochure

RSD designs and manufactures ethylene oxide (EO) sterilisers for the sterilisation of thermosensitive products (those that are sensitive to heat and humidity) such as syringes, catheters, dialysis cartridges, plastic dressings and sutures.

Air Purification System: Things Consider During Design of EtO Sterilization Plant

Recently, serious environmental issues have occurred in the US and raised up the consciousness of manufacturers and Ethylene Oxide sterilizer users. The ethylene oxide is carcinogenic in small quantities, and in some countries, a very strict regulation should be followed to reduce its emission to the atmosphere.

RSD to exhibit at MEDICA 2019

RSD Engineering Solutions will be showcasing their latest ethylene oxide sterilisation solution for the pharmaceutical and medical industries at MEDICA 2019.

SEC Signature Dir is ATEX certificated, Thanks to RSD

RSD, specialising in ethylene oxide sterilisation equipment, has gambled on the SEC Signature Dir sensors of the American company Sensor Electronics Corporation, taking care of all the process in order to get the ATEX Certification (Explosive Atmosphere normative), mandatory in Europe.

Gas mixtures for Industrial EO Sterilisation

Ethylene oxide (EO or EtO) cycles are typically based on the control of humidity, flow, pressure, temperature and EO concentration time, the latter of which is an important factor (usually set between 400-800mg / l) and is directly linked to the dwell time, impacting the production cost.

EO Sterilisation Equipment

RSD has developed a specific control system for the industrial ethylene oxide (EO) sterilisers.

What is a Turnkey EO Sterilisation Project?

First of all, it should be explained that the ethylene oxide (EO) is used for the sterilisation of temperature-sensitive materials, which are very common in medical devices such as syringes, catheters, latex gloves, multi-lumen tubing products, equipment with integrated-electronics and some plastic tubes.

RSD’s ETO-Based Sterilisation Equipment for Temperature-Sensitive Products

Due to the new technology and development of new materials in medical device companies, various products cannot be sterilised with the traditional methods, as per steam sterilisation. For many years, the ethylene oxide (ETO) sterilisation process has become one of the most used technologies for these kinds of products.
