The seminar was organized by TANGRA HVAC Academy in collaboration with the German company for fans and electric motors Ziehl Abegg. Their representative, Mr. Christian Gorbach, arrived specifically for the event and outlined the changes and improvements of the European legislation and requriments for higher efficiency under EU Regulation 327. He drew attention to the choice of fans and pay-back period, as well as the increasing use of EC motors for fans. The course also include comparison between AC and EC fans, as graphically representation of the energy consumption of motors IE2/IE3/IE4/IE5.
