Dorin H Series H 851 CS Semi-Hermetic Compressor

For professionals seeking high efficiency in commercial and industrial refrigeration systems, the Dorin H Series H 851 CS Semi-Hermetic Compressor delivers powerful and stable cooling performance in low and medium temperature applications with 42.81 m³/h displacement and R404A / R507 refrigerant. Its Italian origin and robust reciprocating body provide long-lasting operation in cold storage warehouses, supermarket display systems and process cooling lines.

Wide Operating Range and High Cooling Efficiency

The H 851 CS is designed to operate with R404A and R507 refrigerants over a wide evaporating range from -5 °C to -45 °C. This makes it a flexible solution for both medium-temperature and deep-freeze applications. Thanks to its semi-hermetic design, the motor and compressor are integrated in a single body, which means ease of maintenance and a long service life. Its cylindrical body with cooling fins improves heat dissipation, ensuring stable performance even under heavy operating conditions.
