KCG series gas coolers are made with corrugated aluminum fins and copper tubes with increased thickness, ensuring optimal heat exchange and long life. Heat exchangers are optimized to achieve maximum performance over a wide operating range.
\nThe fin pitch is 2.5 mm for all versions, different pitches are available upon customer request.
\nThe range consists of the following models:
\n\u2022 Fans diameter 450 mm;
\n\u2022 Fans diameter 560 mm;
\n\u2022 Fans diameter 630 mm;
\n\u2022 Fans diameter 800 mm.
\nAC fans with phase-cut adjustment, or electronically switched EC fans with 0-10 V signal are available. In
\nfunction of customer needs the fans can be arranged in a single row or in two rows. They are compatible with the natural refrigerant R744 in transcritical applications, designed to guarantee a PS of 130 bar. The body features a robust and durable design, made of RAL7035 grey painted 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. EC electronic fans are available upon request, 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>
