The S-4 series comprises oil-lubricated screw compressors in the 110 to 160 kW range
The large air cooling ducts are designed to ensure not only top-class cooling capacity, but also a reduced noise level. The fans run at extremely low speeds, and if you wish to reduce noise and energy consumption even further, you can choose frequency regulated fan control as an optional extra.
The compressor gear is encapsulated, allowing you to keep maintenance to an absolute minimum. At the same time, the larger screw helps to reduce the revolution speed, increase efficiency and cut energy consumption.
Good to know about the new S-4 compressor:
Energy consumption in accordance with DIN EN ISO 50001
Insulation made of energy-friendly, non-combustible material that reduces noise even further thanks to its adsorption capacity
The vertical oil separation tank means less oil residue, minimal loss of pressure and a long service life
Compatible with other compressors (6 DI, 2 DO (Relais), RS485, 2 AI, 1 AO, PT1000)
