Semi-Hermetic Refrigeration Compressors Dorin

Quiet Operation and Low Vibration Levels

The crankshaft of each compressor is individually balanced. The use of Computational Fluid Dynamics (CFD) methods is our advantage, allowing for the optimization of internal flow motion.

All Models are VFD (Variable Frequency Drive) Compatible

Optimal bore-to-stroke ratio and motors with increased resistance to high temperatures enable operation over a wide frequency range.

Highest Level of Efficiency

Use of the latest coatings to reduce friction and improve lubrication.

Patented Oil Retention System Minimizes Oil Carry-Over (for models with oil pump)

Increased system efficiency by reducing oil injection from the oil separator and maintaining higher oil viscosity in the compressor crankcase.

• All Compressors are Suitable for HFC and HFO Refrigerants
• Salt Spray Resistance Test, certified for 1000 hours (NSS Test according to UNI EN ISO 4628, parts 2,3,8 - Assessment Method: UNI EN ISO 9227)
• Compact Dimensions and Reduced Weight

Optimal ratio of displacement to crankcase size.

Technical Features of H Series

• Increased reliability and efficiency due to an optimized valve plate design.
• Terminal box with IP65 protection rating.
• Motor reliability is confirmed by its resistance to high temperatures.
• Forced lubrication system, including the piston pin (for models with oil pump).

H Series– Displacement from 4.42 m³/h to 244.78 m³/h
