The optimum efficiency of the internal compression, guaranteed by the innovative Robuschi rotor profile, means less noise during the compression phase. This is due to the low rotation speed (max. 6,000 rpm) of the rotor and the absence of a step-up gear, along with special silencers and a noise-reducing enclosure (also available without sound hood - WL version), guarantee even low noise levels from the compressor, thus allowing installation in a variety of applications.
Forced lubrication system
The compressor is equipped with an oil pump integrated directly into the compressor, eliminating the need for another electric circuit and therefore reducing energy consumption.
Maximum energy efficiency
The innovative and unique profile of Robuschi's rotors optimises the ratio between capacity and pressure thanks to the maximum performance of the internal compression. This increases the efficiency of the ROBOX screw unit. Its characteristics ensure high efficiency (>75%) in a wide range of rotation of the compressor (from 100% to 25%), by reducing the energy consumption in any working condition. The high degree of efficiency of ROBOX SCREW plus its reduced maintenance costs guarantee a quick return on the initial investment (2 years on average depending on the application and the operating conditions).
The compressor offers a turndown capability in flow to meet the needs of the customer. It's also suitable for intermittent use with frequent stops and restarts to best satisfy the specific process requirements. The belt drive ensures the right capacity for the application and also allows the installation of the motor most suitable for the power absorbed by the compressor (therefore operating at optimum efficiency).
