he new Keyfrost machines stand out for being eco-friendly, from
\nthe design phase all the way through to machine decommissioning.
\n\u25cf Design aims for energy efficiency.
\n\u25cf Production aims for minimal waste of materials.
\n\u25cf Thanks to the protection and safety devices, the machine aims for
\nmaximum durability.
\n\u25cf Most of the components are recoverable and recyclable when
\ndecommissioning the machine.
\nCompact systems
\nThe new machine range aims not only to limit waste but also to
\nmake the thermodynamic systems as compact as possible without
\nsacrificing efficiency and reliability. Compactness also guarantees
\na lower use of refrigerant, thereby reducing the impact of the
\nmachines on our planet.
\nWide choice of options
\nThe machines can be customised for final use and a series of basic
\noptions are available, including treatment of materials against
\ncorrosion, micro-door and acoustic signalling.<\/p>\n<\/div><\/div><\/div>

I monoblocchi -SW funzionano con un ciclo a compressione di vapore subcritico in R744 (CO2) e sono condensati ad acqua. Poich\u00e9 la macchina non \u00e8
\npredisposta per un lavoro in ciclo transcritico, assicurarsi di leggere il manuale di installazione prima di mettere in moto la macchina. Le apparecchiature
\nfrigorifere Keyfrost sono macchine agroalimentari (DIRETTIVA MACCHINE 2006\/42\/EC ), destinate al trattamento dei prodotti alimentari. La macchina
\n\u00e8 destinata alla conservazione di derrate e\/o prodotti \u201cfreschi\u201c alle temperature indicate negli allegati. \u00c8 stata progettata per poter lavorare con
\ntemperatura ambiente da +16\u00b0C a +43\u00b0C (classe T).
\nTemperatura dell\u2019acqua di raffreddamento deve essere sempre inferiore ai 20\u00b0C. \u00c8 stata progettata per mantenere una determinata temperatura in
\nuna cella frigorifera predisposta a tale uso. La macchina non \u00e8 destinata ad essere installata e utilizzata in celle poste all\u2019esterno. La macchina non \u00e8
\ndestinata ad essere installata e utilizzata in una atmosfera a rischio di esplosione.
\nOgni uso al di fuori di quelli consentiti viene considerato \u201cuso improprio\u201c e pertanto il costruttore ne declina ogni responsabilit\u00e0.
\nL\u2019unit\u00e0 non \u00e8 destinata ad essere usata per la conservazione di prodotti che sviluppano sostanze corrosive.<\/p>\n<\/div><\/div><\/div>
