Increased capacity and reduced noise levels for all industrial sectors, including sensitive and demanding environments like healthcare, food and beverage manufacturing, and in areas with adverse conditions, such as the construction and mining sectors and foundries.

BOGE has released its new S-4 series of screw compressors for the 45 to 75 kW performance range. Customers can benefit from all the benefits of the series, including everything from efficient, quiet and reliable running to simplified servicing.

It’s not only in foundries, the mining and construction industries where dust and dirt can hamper even the best efforts to generate reliable, continuous compressed air. Other areas, including the food industry, find themselves facing challenging conditions. And this is where a compressor with a virtually maintenance-free hermetically sealed direct drive comes into its own: wear and tear is minimised, which increases the device’s service life. All the models in BOGE’s S-4 series have this “IntegrateDrive” airend – including the new compressors with a performance range of 45 to 75 kW. 

Compact, energy-saving and efficient

As a leading compressor manufacturer, BOGE has once again expanded the fourth generation of the S series, which now covers the entire 45 to 150 kW performance range. All models are characterised by quiet, reliable operations and have excellent efficiency values. 

The compressors generate high free air delivery at low specific power consumption. The energy use of the new 75 kW compressor has been reduced by over 12 percent compared with its predecessor, while the free air delivery has increased by almost 9 percent. 

The generously sized components reduce internal pressure losses, and with a footprint of just 1.20 m x 2.00 m, the housing of the new models is considerably smaller than its older siblings. These new compressors come with particularly high-performance, low-energy IE4 motors and permanent magnet motors fitted as the industry standard.  

Simple maintenance and low sound pressure level

The innovative vertical oil separation concept ensures very low residual oil content, minimal pressure losses and a long service life, while the internal cartridge is quick and easy to remove and replace. Maintenance takes place from two sides with just a few simple movements – the intake filter is accessible, and both the oil and air coolers can easily be removed and cleaned. 

These new models are special, thanks to their quiet running, and we’ve been able to reduce the noise in the 45 kW performance class by more than an extra 8 dB(A),” explains Nalin Amunugama, General Manager, BOGE Asia Pacific. “The reduction allows for greater flexibility because the compressor can now be used in more sensitive environments.” 

“With the latest models in the S-4 series, BOGE offers companies with reduced compressed air demands reliable, energy-efficient technology, even in situations where temperatures can exceed 40°C. For these critical installation conditions, BOGE’s high-temperature design provides improved cooling,” Nalin says.
