About Us


RGI bioSteryl Tech Ltd is an engineering company, specialized on Cultural Heritage, which is well-known and appreciated throughout the world because of the produced machineries and the provided services, all dedicated to the care, preservation and conservation of artworks.

In particular RGI is a global leader in the field of anoxic nitrogen-based disinfestations by  the VELOXY® System.



RGI was funded in 1992 under the name of RGI Resource Group Integrator, by the courageous Ercole Gialdi’s initiative who immediately foresaw the potential of anoxia in the field of cultural heritage, in spite of the fact that studies about this argument were still at their beginning. Research began immediately and the first prototypes of the VELOXY® System were carried out, followed by great successes until 1998 when the certifications and the attestations of European SAVE ART project were performed.

RGI is the pioneer of the anoxic method and because of the VELOXY ®Project, the first at global and European level, it was possible to work closely with museums, libraries and institutions, responsible for the preservation of cultural heritage; because of it RGI deepened its knowledge about these organizations and designed new machineries starting from the needs and the ideas of professionals who work in that contest.

In 2000 the first prototype of the CONSERVER ®were performed, devised with the collaboration of innovative managers of Libraries and designed by RGI. It allows the vacuum storage of paper materials. It was originally designed for newspaper libraries, which have always had problems in conserving magazines and newspapers, then the CONSERVER® immediately becomes a focal point in the sector and, due to its continuous evolution (last version 3.0 carried out in 2013), it is being increasingly used mainly for the conservation of paper materials, but also metallic and other materials.

The VELOXY® and the CONSERVER Systems are now widely known and it can be said that a lot of people, involved in the Cultural Heritage field, are interested in the method of anoxia. After meeting a famous restorer, who had been already using the VELOXY® System, it was devised and designed a new vacuum system in order to create high quality coverings which can be used for the restoration of paintings. In fact it was produced the first prototype of VACUUMART by following the suggestions from the typical needs of  restorers.

 The use of the VELOXY® System is becoming more popular and the continuous improvements have contributed to make the VELOXY® System increasingly unique in the market despite unsuccessful attempts to imitate it, but RGI wanted to do even more.                                                                 

Even though the VELOXY® System and the generated anoxic environmental ensure the complete elimination of any insect pests at any life stage, it must be noticed that molds and fungi do not seem to be eliminated through anoxic treatments.

Consequently RGI decided to improve the prevention and, from 2004 to 2006, another European applied research project, called ABIOS®, was developed. This new machine was designed in order to safeguard the artworks from the contamination of bacteria and micro-organisms that are also able to create attacks from molds and fungi. This project shows that the ABIOS® is not only effective on artworks but it also obtains excellent results in inhibiting the spread of bacteria, which is the main source of human diseases.

As a result, the ABIOS® was patented by RGI. Its effectiveness, ease of use and safe installation, even in areas frequented by people, ensure a 360° use of the ABIOS®.



It is evident that the mission of RGI is focused on IPM (Integrated Pest Management), in other words on the integrated management of the damages caused by insect pests.

IPM has its origin in the field of food industry, where the systematic use of pesticides has been discouraged or not allowed. In the world of Cultural Heritage, the acronym IPM takes on a wider and more fundamental meaning; in fact on this issue an European law has been developing. IPM, then, consists in the development and implementation of procedures and protocols aimed at the preservation of Cultural Heritage, prevention, restoration and management of infestations.

The adoption of this approach has enormous advantages to the safeguarding of Cultural Heritage, people’s health and safety and the protection of the environment. In addition, once it will be well consolidated, it has the benefit of being less expensive than other approaches exclusively passive or reactive.
