About us

Prefa Alfa as was established by Slovak and Swedish founder with the fundamental target to replace plastic-made sewage system with sewage system made of concrete. The company uses its knowledge deliberately in processing and moulding concrete, not only used for sewage system. The company possesses the latest technology for production of sewage system made of concrete. Furthermore, the company has acquired all necessary technology needed for vacuum insulation, measurement of concrete properties, manipulation and moulding equipment. With the reference to such technology, the company could finally start its own research and development. During the last five years, the company has been developing technologies for heat accumulation gained from renewable energy source. The main objective was construction of vacuum-insulated containers made of concrete, that would enable the customer to accumulate heat up to 500°C, where molten salts were chosen to be the accumulating medium. The strategic ambition of the company is to become a leader in technologies for mid-potential heat accumulation. We would like to be the first company that would come to mind to potential customers, when they consider the heat accumulators.

The company PREFA ALFA a.s. is also a member of Interest Association of Legal Persons called ATASAC – Advanced Technology and Science Applications Centre, which interests are based on support of applied research in the energy and innovative materials sectors. Furthermore, the association ATASAC provides cooperation between universities and industry in Slovakia and worldwide. Additional ATASAC´s ambition is representation of members´ interests in EU structures and other multinational corporations.
