DORIN H350SB - COMPRESSOR
Semi-hermetic DORIN compressors are modern solutions designed for maximum efficiency and reliability. Engineered to meet evolving market demands and to operate with new refrigerants (HFC and HFO), they combine high performance with quiet and stable operation. The capacity range of DORIN compressors spans from 4.42 to 244.78 m³/h, with nominal power from 0.5 to 90 HP.
DORIN stands for Italian precision and quality, certified according to EN ISO 9001. All compressors are 100% manufactured in Italy, ensuring the highest production standards. They feature low vibration levels, inverter compatibility, and a patented oil return system that minimizes losses and enhances reliability.
The H350SB model is a compact semi-hermetic compressor with a displacement of 17.53 m³/h, designed for operation in demanding refrigeration systems. It combines high build quality with the ability to operate over a wide frequency range from 30 to 70 Hz, allowing flexible adaptation to various operating conditions.
The H350SB compressor is intended for low evaporating temperatures typical of freezing and deep-freezing applications. Its reinforced construction and optimized motor cooling ensure reliable operation even under very heavy-duty conditions. Thanks to its compatibility with HFC and HFO refrigerants, the SB model maintains high efficiency at deep evaporation levels. Compact dimensions and available accessories make integration easy in cold stores, freezing tunnels, and equipment requiring operation at extremely low temperatures.
