MULTICOMPRESSOR CASCADE UNITS IN SUBCRITICAL CONDITIONS
The DIONISIO line, part of the ECO3 series, includes condensing units using carbon dioxide (CO2) as refrigerant, in subcritical conditions, equipped with two or more reciprocating semi-hermetic compressors connected in parallel. The line is available without housing for indoor installation (CKCA) and with housing for outdoor installations (CKCC). Condensation is carried out with dry expansion evaporation of a synthetic (R134a, R513a, R449a, etc.) or natural (R717) refrigerant which, by evaporating, removes heat from the CO2 making it to condense. An air heat sink is also provided to cool the compressed CO2.
The range includes a liquid receiver with an internal coil which, during the stand-steel or black-out phases, allows the liquid receiver to cool through its connection to an external unit with an autonomous system (back-up unit).
The series is made on a sturdy self-supporting carpentry made with electro-galvanized painted sheet metal profiles and press-folded sheet metal profiles. All sheet metal components polyester powders coated, polymerized in an oven at 180 ° C color RAL 7035 (other RAL on request).
On request, the series DIONISIO – CKCA/C is available with different optional depending on the specific needs of the system required.
