All the models provide for a system of subcooling of the liquid which allows to increase the cooling capacity and efficiency of the entire plant.
The mechanical dimensioning of all the components has been optimized specifically for the particular characteristics of the low-temperature applications, making these extraordinarily reliable compressors.

In this range of compressors, the integrated frequency inverter enables continuous adjustment of capacity; this allows to minimize the variations of the suction pressure and avoids continuous switching-on and off of the compressor, obtaining important savings on energy costs, a greater thermal stability of the system and a significant lowering of the noise level.
The inverter is factory pre-programmed, it is operated by an external PID controller or via direct connection of a pressure transducer to be mounted on the suction line.
The adjustment of all parameters that control the inverter can be customized to suit the specific application.

A wide range of compressors is available with construction and security features according to the requirements expressed by the European Directive ATEX 2014/34/EU (group 2).
These compressors can operate in classified zone potentially explosive (Zone 2) due to the presence of flammable gases.

Open type ATS series
Built with only three blocks of moving parts, this twin screw compressor reaches high levels of reliability and efficiency.
Much appreciated in application such as industrial refrigeration and air conditioning thanks to its balanced operation and low noise levels both at full and part load.
The perfect execution of the mechanical shaft sealer, makes it suitable for all refrigerants.
The compressor can be operated with standard commercially available electric motors and connected with direct coupling joints.

In the industrial process refrigeration systems operating with ammonia, in particular those for the production and food processing, but even in marine sector, strong and efficient compressors are required.
Our range of compressors for NH3, driven by the electric motor by means of joints for direct transmission or by belts and pulleys, perfectly meets those needs, thanks to robustness, compact overall dimensions and high efficiency.

The range includes three models with 6-cylinder and displacement from 146 to 188 m3/h (50Hz) and a wide selection of accessories that multiplies the versatility.

The range of compressors for subcritical CO2 applications, has been developed taking into account the most recent requirements from the refrigeration technologies and by manufacturers of refrigerating applications for supermarkets.
The compressors are ideal for use with hybrid systems (ie. cascade system) and, in combination with the compressors Frascold TK series for transcritical CO2 applications, they offer the possibility to built-up multi-compressor installations for medium and low temperature (booster systems).
The parameters considered during designing phase, allow the use of SK models in an extended working range with higher evaporation temperatures and condensation. Similarly, also the maximum permissible stand still pressure Pss is higher, allowing the use of these compressors even when the increase of pressure represents a limitation for building the plant itself.
