The compressors have been developed with a compact and innovative design, and they are suitable for universal use in commercial and industrial applications. This range of compressors is equipped with a mechanical system that allows an efficient capacity control. All the compressors can be installed in parallel with others compressors having the same size or different size, allowing great flexibility of use.



The compressors of the RTS and NR series have been developed for universal applications in medium to low temperature refrigeration systems, and are adapted for operating in parallel multi-compressor systems. They cover a refrigeration capacity range of up to 634 kW and are available in 34 different models, with volumetric capacity at 50 Hz from 120 to 538 m³/h. Designed to function continuously for long periods without stoppages and without intensive maintenance operations, they guarantee a superior coefficient of performance to competing products and implement technical solutions dedicated to a reduction of noise and pulsations. Accurate planning, production entirely “made in Italy” and

quality control methods guarantee excellent performance and reliability.
