Destined use, intended and unintended uses<\/strong>
\nKeyfrost\u2019s refrigerating equipment is classed as food and agricultural machinery (MACHINES DIRECTIVE 2006\/42\/EC), destined for the
\ntreatment of food products.
\nThe machine is designed for the conservation of foods and\/or \u201cfresh\u201d products at temperatures indicated in annexes.
\nIt has been designed to work in ambient temperatures from 0\u00b0C a +43\u00b0C (class T).
\nIt has been designed to maintain a set temperature in a refrigerated cold room suitable for such uses.
\nThe machine is not designed for use in cold rooms situated outside.
\nThe machine is not designed for installation and use in an environment where there is risk of explosion.
\nAny use other than that permitted shall be considered improper, and in this case the Manufacturer will decline all liability.
\nThe machine is not designed for the conservation of products, which produce corrosive substances.<\/p>\n<\/div><\/div><\/div>

Use of ultra-low GWP refrigerants<\/strong>
\nThe new range of Keyfrost machines includes the use of brand new ultra-low GWP refrigerants. With a GWP of only 146, the R455A stands as the definitive solution for the future of commercial and industrial refrigeration for low and medium temperatures.
\nAfter several tests and studies based on the entire cold chain, it has been demonstrated that the TEWI of machines operating at R455A is also more favorable thanks to the coolant COP but also to the ease of management of machines that do not involve particular complications for the user compared to older machines at R404A.<\/p>\n

Safety<\/strong>
\nThe refrigerant used is composed of a slightly flammable azeotropic mixture (A2L according to ISO 817). However, the use of R455A is made safe (in compliance with the main safety regulations) thanks to the particular flammability properties of the refrigerant including:
\na) Relatively high lower flammability limit of \u201911.8% (LFL);
\nb) Relatively low upper flammability limit compared to the lower flammability limit 12.9% (UFL);
\nc) Minimum ignition energy greater than 1000 times that of propane;
\nd) Flame propagation speed less than 1.5cm\/s.<\/p>\n

<\/i><\/i><\/span>Regulatory compliance<\/span><\/a><\/h4><\/div>
\n

Keyfrost monoblocks are designed, built and distributed according to the relevant current regulations and regulations.
\nIn particular, the entire range respects, where relevant:
\na) The maximum charge limit imposed on machines using A2L refrigerants according to EN 378-1, without having to take into account the reference volume, the type of application, the access class of the application and particular safety precautions due to the nature of the refrigerant itself;
\nb) Design of the refrigeration system according to EN 378;
\nc) The PED directive with maximum classification 2;
\nd) The F-GAS regulation;
\ne) The legislation on the electrical equipment of machines EN 60204-1
\nf) The Machinery Directive (2006\/42\/EC);
\ng) EC Regulation No. 765\/2008;<\/p>\n<\/div><\/div><\/div>

Eco-friendly vision<\/strong>
\nThe new Keyfrost machines are characterized by their eco-compatibility: from the design phase to the decommissioning phase of the machines.
\n\u25cf The design aims for energy efficiency.
\n\u25cf Production aims for minimal material waste.
\n\u25cf Thanks to protection and security devices,
\nthe machine aims for maximum durability.
\n\u25cf Most of the machine was decommissioned
\ncomponents are recoverable and recyclable.<\/p>\n

Compact systems<\/strong>
\nThe new machine range aims not only to limit waste but also to make thermodynamic systems as compact as possible without sacrificing efficiency and reliability. Compactness also ensures less use of coolant, thus limiting the impact of machines on our planet.<\/p>\n

Wide choice of options<\/strong>
\nThe machines can be customizable according to their intended use and a number of basic options are made available such as material treatment against corrosion, microport, water condensation, tropicalized versions, acoustic siren etc.<\/p>\n<\/div><\/div><\/div>

<\/i><\/i><\/span>Maximum refrigerant charge R455A<\/span><\/a><\/h4><\/div>
\n

Split systems are supplied without refrigerant charge. Machines must be installed by qualified technical personnel
\nFollowing the main national and regional standards, R455A refrigerant is classified as A2L (slightly flammable) and as such has maximum permissible charge limits. Refer to EN 378 part 1 and\/or local regulations. As an example, the graph showing the maximum charge of a system classified as Access Class II b is shown. Cibin srl does not assume responsibility for non-compliance with these limits.<\/p>\n
