Every two years sees the staging of the Internationally Important Mostra Convegno Expocomfort, with this years event being held on 27th to 30th March in Milan. Once again Danfoss was in attendence presenting our latest products and solutions for both Air Conditioning and Refrigeration. New VZH: the breakthrough in high efficient compressor solution for all commercial applications. ThenewPerformer®VZH,R410A scroll compressor, second generationoflargesizevariable speed scroll compressor after the release of VSH in January 2010,willopennewhorizonfor all commercial applications. Firstvariablespeedcompressor achieving 25TR at standard ARI conditions, VZH will also provideunmatchedperformancelevels. The Danfoss stand was divided into 2 main areas, one for Air Conditioning products and the other for Refrigeration products. IntheAirConditioningsectionproductsdisplayedincluded compressors, heat exchangers and controls whilst in the Refrigeration area were packaged condensing units, compressors,commercialandindustrialcontrolsalongwith electroniccontrolsfortheFoodRetailindustry. Danfossalsoparticipatedintheseminarswithpresentations on "Heat pump and liquid injection technology", Variable speedforHVAC,closecontrol,industrialapplicationsandalso Turborcompressorsandapplications. Highlightsfromtheshowincluded: Optyma Plus™ New Generation Condensing Units As already introduced in a previous edition of Cooling Matters the new generation ofthesilentPlug&Playseries ofOptymaPlus™Condensing units were displayed at the stand. Optyma Plus™ New Generation offers the same robust quality with added technology, for outdoor cooling units.
