The company by the name Konstantelos founded by George Konstantelos in Greece, entered the field of high-tech construction in 1959. He began great technological breakthroughs and conquests in the technology field, manufacturing a small production of electronic and mechanic machinery.
   In 1960 constructed the first induction generator (high-frequency) 15KW power with two EIMAC tubes 3CX3000 triodes at push pull technology for surface hardening of shafts and for gears. The volume of this machine using high voltage (5000V) for the electron tubes exceeded the volume of a room.
   The following years came with constructions of induction generators with greater power, AM and FM radio transmitters, TV transmitters, radio constructions for the Army, microwave radio Links, diathermies, broadcast antennas and electronic support structures for automated devices and systems. In the field of mechanical structures are made constructions in small production  of  portable hydraulic steel cutters  and  steel benders  for  building  construction

applications and nitrogen hydraulic presses for hot iron forming (forging technology).
   In 1994 the Konstantelos brothers having at their disposal this vast range of activities, knowledge and experience and the help and support of the University of Patras in which they studied, undertake the company and expand it. With continuous effort by applying all the modern technological methods and the use of electronic computers and programming support they evolve the machinery that are now separated into 3 classes: a) induction generators, b) nitrogen hydraulic presses, c) automations.
   Our theoretical knowledge on these 3 areas and the 50 years experience in construction give us the ability to provide integrated solutions to customer needs for better production and quality.
