ROXSTAcube integral

By TEKO, published May 09, 2017

ROXSTAcube integral efficiently generates refrigeration in refrigerated shelves, islands and cold rooms. The waste heat from the cold production process is used by the ceiling ventilation to heat the market. In addition, the heat pump function replaces the heating system in winter and the air conditioning system in summer. In this integral concept, the quality of the refrigerated product always comes first.
