The key to the success of the HallScrew, a single screw ammonia compressor from J&E Hall, is its outstanding reliability. With only three basic moving parts involved, a main rotor which meshes with two diametrically opposed star wheels, results in balanced compression. The HallScrew single-screw compressor is extremely robust and offer a long main bearing life of over 100,000 hours.
The HallScrew also features a high efficiency capacity control mechanism to regulate the capacity with corresponding reduction in power input. For ease of maintenance, the side casing canbe removed to give access to all parts without removing the machine from its installation.
J&E Hall has now launched additional models to the open drive range which have been designed and manufactured using worldwide group facilities. New models will enhance the existing range and complete the series between 898 – 2100 m³/h.
