The KCs are made with corrugated aluminum fins and rifled tubes, designed to ensure optimal heat exchange and long life. They are designed and designed for green refrigerants and to ensure a PS of 30 bar. The body features a robust and durable design, made of RAL7035 grey powder-coated galvanized steel sheet, and allows for wide accessibility to the interior elements. There is an electric duct along the entire development of the machine to allow the passage of cables.
\nFan motors comply with the Ecodesign Directive 2009\/125\/EC, applied by EU Regulation 327\/2011 and bear the CE mark.
\nEC electronic fans are fitted as a standard, for optimal modulation of the exchanger capacity. Protective grilles are designed to prevent contact with moving parts of the fan.<\/p>\n<\/div><\/div><\/div>

The KCs are made according to the following standards:
\n\u2022 EN 378
\n\u2022 Heat exchangers comply with Directive 2014\/68\/EU for pressure vessels and assemblies (Pressure Equipment Directive PED);
\n\u2022 The ranges comply with the Machinery Directive 2006\/42\/EC, and the Low Voltage Directive 2014\/35\/EU;
\n\u2022 Electric motors comply with EN 60335-1 and have CE marking<\/p>\n<\/div><\/div><\/div>
