Sabroe SAB 283 compressors are large units with capacities of 3326 and 3998 m3/h swept volume (50 Hz), and a patented method of adjusting the Vi to match the system pressure ratio. They can be used with all the most common refrigerants. The SAB 283 range features the only screw compressor package design that integrates key components into the framework itself. This results in a sturdy, compact unit with only a small footprint and with less external tubing, extremely low vibration and quiet operation. Download product description here.
