ALUP’s Sonetto models feature a revamped air end element, which facilitates an increase of 15% in free air delivery (FAD) output and a reduction in energy consumption on selected models of up to 12%.
At the same time, its development of a range of options allows the compressor to operate on a low duty cycle typically seen on piston machines, where the demand for air is intermittent. The combination of an anti-condensation oil heater, tropical thermostat and a larger 500-litre air receiver thereby allows the unit to operate on very low duty cycles and also avoids the issue of condensation forming within the oil.
Where there is a need for large volumes of air on continuous demand, such as an industrial production process, ALUP’s Sonetto belt-driven screw compressors can be configured accordingly. Units are available either floor-mounted, tank-mounted or tank mounted with refrigerant air dryer, the latter version delivering a 55% reduction in global warming potential (GWP) over previous-generation screw and dryer packages, says ALUP. This is a result of the change of refrigerant gas in the refrigerant dryer: from R134a HFC to R513a. Compressor power ranges from 2.2 to 7.5kW in either eight- or 10-bar versions. Distributors also have the option of a pressure conversion kit.
Commenting on the launch of its upgraded compressors, Mark Keen, Business Line Manager at MultiAir UK & Ireland, which supplies the ALUP brand to a network of distributors, said: “These latest innovations to ALUP’s Sonetto range of screw compressors have been developed in conjunction with customer requirements, whilst recognising the urgent need to lower carbon emissions in every sector. Improving the work environment for operators by minimising noise has also been a key factor, so these upgraded machines provide a compelling overall business solution in a challenging economic climate.”
