Keyfrost Environmental Sensitivity
Regulation (EU) no 517/2014 of the European Parliament and of the Council of 16 April 2014
on fluorinated greenhouse gases and repealing Regulation (EC) No 842/2006.

Products and equipment: Where relevant, the GWP of mixtures containing fluorinated greenhouse gases shall be
calculated in accordance with Annex IV, as provided for in point 6 of Article 2.

Refrigerators and freezers for commercialuse (hermetically sealed equipment) that contain HFCs with GWP of 150
or more.

Stationary refrigeration equipment, that contains, or whose functioning relies upon, HFCs
with GWP of 2 500 or more except equipment intended for application designed to cool products to temperatures
below – 50 °C

he new Keyfrost machines stand out for being eco-friendly, from
the design phase all the way through to machine decommissioning.
● Design aims for energy efficiency.
● Production aims for minimal waste of materials.
● Thanks to the protection and safety devices, the machine aims for
maximum durability.
● Most of the components are recoverable and recyclable when
decommissioning the machine.
Compact systems
The new machine range aims not only to limit waste but also to
make the thermodynamic systems as compact as possible without
sacrificing efficiency and reliability. Compactness also guarantees
a lower use of refrigerant, thereby reducing the impact of the
machines on our planet.
Wide choice of options
The machines can be customised for final use and a series of basic
options are available, including treatment of materials against
corrosion, micro-door and acoustic signalling.

I monoblocchi -SW funzionano con un ciclo a compressione di vapore subcritico in R744 (CO2) e sono condensati ad acqua. Poiché la macchina non è
predisposta per un lavoro in ciclo transcritico, assicurarsi di leggere il manuale di installazione prima di mettere in moto la macchina. Le apparecchiature
frigorifere Keyfrost sono macchine agroalimentari (DIRETTIVA MACCHINE 2006/42/EC ), destinate al trattamento dei prodotti alimentari. La macchina
è destinata alla conservazione di derrate e/o prodotti “freschi“ alle temperature indicate negli allegati. È stata progettata per poter lavorare con
temperatura ambiente da +16°C a +43°C (classe T).
Temperatura dell’acqua di raffreddamento deve essere sempre inferiore ai 20°C. È stata progettata per mantenere una determinata temperatura in
una cella frigorifera predisposta a tale uso. La macchina non è destinata ad essere installata e utilizzata in celle poste all’esterno. La macchina non è
destinata ad essere installata e utilizzata in una atmosfera a rischio di esplosione.
Ogni uso al di fuori di quelli consentiti viene considerato “uso improprio“ e pertanto il costruttore ne declina ogni responsabilità.
L’unità non è destinata ad essere usata per la conservazione di prodotti che sviluppano sostanze corrosive.
