New Generation HallScrew Compressors

J & E Hall has added seven new models to the existing HallScrew range, which provide more intermediate capacities with a focus on compact design and efficiency.

The new HSO 4225/6/7, 5200 and 6200 series are the next generation of open drive single screw compressors. Reflecting the very latest innovations in screw compressor technology, the current range up to 2486m³/h now includes models 898 – 2100 m³/h with fixed or variable volume ratio. As with all HallScrew open drive compressors, the new models can operate on all refrigerants including natural refrigerant options.

Key to the HallScrew’s success is its outstanding reliability, utilising only three basic moving parts. A main rotor which meshes with two diametrically opposed star wheels produces balanced compression resulting in extremely long main bearing life of over 100,000 hours and reduced lifecycle costs.
