SC452-035

Product Description:

The SC452-035 screw compressor is part of the SC450 Brushless Servo Controllers series from Pacific Scientific. This model runs with a rated motor power of 4 kW and carries a total weight of around 115 kg, giving it a solid frame for continuous industrial usage. The displacement sits at 35 m³/h at 50 Hz, offering dependable capacity for refrigeration cycles. It includes Polyester (POE) oil, with an oil charge of 3 liters, which helps ensure stable lubrication across varying workloads.

Noise output stays at about 68 dB(A), which is considered moderate for this class. Refrigerant compatibility is broad—works well with R134a, R404A, R407C, and R507—making the SC452-035 suitable for a wide range of systems. Voltage input stands at 400V / 3Ph / 50Hz, which aligns with typical European and industrial plant configurations. This model uses a 1 5/8” suction connection and 1 1/8” discharge connection, allowing for fast installation without needing extra modification to piping. Every component inside the motor contributes to smooth rotation, and the cooling setup helps avoid thermal slowdowns even after hours of continuous industrial usage.

Temperature handling sits between -25°C and +45°C, giving enough range for both low-temp cooling and standard ambient operation. Structure and function are built with the demands of compressors in mind—compact but sturdy, efficient under stress, and resistant to wear. The controller pairing in this series brings smooth brushless performance, and that reduces lag and helps keep internal cycling efficient. From commercial cold storage setups to more demanding industrial environments, the SC452-035 brings dependable capacity and streamlined integration, especially in systems where footprint and refrigerant variety matter. The overall construction focuses on performance without sacrificing long-term durability.
