About us

The organization banks on the acquired knowledge of its founder, Mr. Helder Gonçalves, along almost 50 years in several areas, specially mechanics, electricity and electronics.
In ambit of sterilizing equipment, his professional experience started more than 40 years ago in one of the most important Portuguese manufacturers in the segment, where he participated in the development and construction of sterilizers. He had the opportunity to conclude several studies which he introduced in many sterilizer models. During the time collaborating with that manufacturer, Mr. Helder Gonçalves specialized in the manufacturer’s brand as well as the rebuilding and enhancement of sterilizers of world known brands such as GETINGE.


Later his way passed the SUCH Company where he got in contact with various brands and models of sterilizers, also participating in the development and automation conception for application in sterilizing systems.
He was a pioneer in the development and manufacturing of low temperature sterilizers and sterilization cycles by formaldehyde and ethylene oxide in Portugal.
In 1992 he decided to move from Lisbon to Boticas, a tranquil village in northern Portugal, and started his own Company.
In 1997 his company became a society named Helder Gonçalves – Assistência Técnica de Equipamentos, Lda.


Afterwards the company collaborates and establishes co-partnerships with various institutions, like many national hospitals, searching for optimizing the most appropriate cycles for the necessity of the emergent processes of sterilization, having inserted integral sterilization systems.
Huge projects of sterilization by pure steam in the industry have been in the strategy of the company, helping institutions and international manufacturers in developing the best solution for their needs.
The company obtained certification of its Quality Management System according to ISO 9001 in September 2005.


In February 2007 the certification scope has been enlarged to include Research and Development of sterilization and disinfection equipment.
A big change occurred in the beginning of 2012. The company was divided into two different companies. Helder Gonçalves – Assistência Técnica de Equipamentos, Lda. is now managed by Mr. Helder Gonçalves’ son and is dedicated to the service and maintenance of sterilizers. Mr. Helder Gonçalves himself manages his new company “Sterifast – Sterilization & Disinfection Systems, Lda” which main purpose is the Research and Development of Low Temperature Solutions for Sterilization and Disinfection and is focused on selling turnkey projects to manufacturers as well as consumables and some special components. After successful years developing and enhancing low temperature H2O2 sterilisers and implementing the production of the equipment at big brands, such as Tuttnauer, he sold the company to Belimed to pursue his dedication to research and development of low temperature sterilizer with H2O2. He continued his path with some of the patents and brands he maintained ownership of.


His scientific breakthroughs in the field are unmatched and he passed his most recent developments in one of the most reputable validation laboratories in the United States where he showed and documented the highest penetration capacities for the smallest lumens in orthopedic containers the laboratory has ever seen.

Both his equipment and the sterilization process are protected by the patent PCT/PT2014/000064 with International Publication number WO2016/064288 A1.
Mr. Helder Gonçalves is also the only manufacturer of H2O2 Biological/Chemical Indicator Evaluator Resistometers worldwide who sold this kind of equipment on the global market.
In November 2013 he introduced new systems with technology that allows the use of much lower concentrations of hydrogen peroxide. His path continues developing the most modern technologies in the field to ensure that solutions exist today to serve all people around the world.
