Keyfrost Environmental Sensitivity<\/strong>
\nEuropean regulation 517\/2014 establishes the rules relating to the marketing of HFC-containing equipment and products. One-piece refrigerant machines fall under item 12 and may use refrigerant gases with GWP less than 2500. Keyfrost produces ranges of monoblocks that use different refrigerants including R449A, R290, R455A etc.
\nGiven the increasingly stringent regulations and the technological availability, Keyfrost wanted to develop and support, above all, the expansion of the monoblock range using R455A refrigerant. Where possible it is therefore recommended to use monoblocks at R455A and\/or R290. R455A machines have a 90% lower environmental impact, due to the refrigerant charge, in terms of CO2eq.<\/p>\n<\/div><\/div><\/div>

\n

Use of ultra-low GWP refrigerants<\/strong>
\nThe new range of Keyfrost monoblocks includes the use of natural refrigerants at very low GWP. With a GWP of only 3, the R290 stands as a solution for the future of small-scale commercial refrigeration for low and medium temperatures.
\nOur tests have also demonstrated a significant advantage in terms of TEWI which depends on the GWP but also on all the design solutions adopted.
\nMinor limit charge of 150g<\/strong>
\nR290 is classified A3 meaning it is not toxic but is highly
\nflammable. Depending on the application and the available volume, it is possible to calculate a maximum refrigerant charge that makes the machine safe from any accidents related to the flammability of the fluid.
\nBelow 150g refrigerant charge there are application limits as 150g is never sufficient to create a potentially hazardous atmosphere.
\nThe Keyfrost R290 monoblocks are all loaded with 150g
\nor not with a refrigeration circuit.<\/p>\n<\/div><\/div><\/div>

Destinations of use, intended and unintended use<\/strong>
\nKeyfrost refrigeration equipment is agri-food machinery (MACHINE DIRECTIVE 2006\/42\/EC), intended for treatment
\nof food products.
\nThe machine is intended for the preservation of \u201cfresh\u201c foodstuffs and\/or products at the temperatures indicated in the annexes.
\nIt was designed to be able to work at room temperature from +16\u00b0C to +43\u00b0C (class T).
\nIt was designed to maintain a certain temperature in a cold room designed for such use.
\nThe machine is not intended to be installed and used in cells located outside.
\nThe machine is not intended to be installed and used in an atmosphere at risk of explosion.
\nAny use outside the permitted ones is considered \u201cimproper use\u201c and therefore the manufacturer disclaims any responsibility for it.
\nThe unit is not intended to be used for the storage of products that develop corrosive substances.<\/p>\n<\/div><\/div><\/div>
