Boge S-4 compressor for low energy consumption and quiet operation

27 October, 2017

Boge has launched its S-4 screw compressor, which, according to the company, offers ultra-low energy consumption, whisper-quiet operation and exceptionally easy maintenance.

All the components in the Boge S-4 are integrated in the state-of-the-art airend, which offers noise-optimised cooling air, a low-speed radial fan, elasticated ‘SilentMount’ bracket, easy-access design, and modern separator technology for fast, convenient and safe cartridge changes.

At the heart of the S-4 series is Boge’s effilence ‘IntegrateDrive’ airend with integrated gears. The enclosed, low-loss, maintenance-free integrated gear is lubricated via the compressor’s oil circulation. All components are large to ensure low internal pressure losses and maximum efficiency and, because the new airend can be mounted at the optimum operating point, all performance ranges and pressures can be variably controlled.

The radial fan runs at a very low speed, which has a positive effect on the sound pressure level (below 74 dB/A). It is also said to reduce the drive power of the fan, increase efficiency and cut energy costs. The fan can also be combined with a speed controller to further reduce the noise level and power consumption

All the sound insulation panels of the S-4 can be removed with just a few hand movements to allow easy access to all components. Maintenance can be carried out from just two sides, and details such as the drawer principle for the oil and air cooler or the use of Victaulic clamped connections create the most maintenance-friendly screw compressor available.

No need for pipework or connecting cables

Parts requiring maintenance are within easy reach in the compact module and there is no need for pipework or connecting cables.

The AirShield control can anticipate operating states and adapt to expected pressure and temperature sequences. Even the standard base control unit offers automatic frost protection mode and integrated leakage monitor. The optional focus control 2.0, meanwhile, can monitor up to four connected compressors.

The S4 also features innovative oil separation technology. The redesigned vertical oil separation system ensures a very low residual oil content, minimal pressure losses and a long service life for the separating element. Changing the inner separation cartridge is made fast and easier by the accident-proof swivel mechanism.
