New BOGE scroll air compressors for Oil-Free compressed air
July 31, 2017
Whether in medical technology, pharmaceuticals or the food processing industry – cleanliness is paramount. BOGE Kompressoren has now extended its EO range of oil-free scroll air compressors to ensure full protection from contamination. The Boge EO Series is available in simplex, duplex, triplex or quadplex packages covering the full performance range of 5.5 kW, 11 kW, 17 kW and 22 kW. Alternatively in an upgrade-ready version, the EO 11, for example, can be ordered with an integrated or separate refrigerated compressed air dryer, and mounted on a tank as a duplex system. Its compact design combined with operation at 59 dB(A) means there is no problem installing the system next to the workplace.
BOGE’s oil-free EO air compressors meet the requirements of oil-free compressed air for sensitive applications. The recipe for success here is the scroll air compressor technology operating without oil lubrication. The aluminum spirals in the air compressor chamber interlock but do not touch. The resulting compressed air is pulsation-free and absolutely free of oil. In the medical sector, such as dental practices and clinics, pure compressed air protects the health of patients while preventing the contamination of highly sensitive equipment. “When it comes to food processing for example, such as wine bottling, EO scroll air compressors are perfect for connecting to a nitrogen PSA generator from BOGE's NP series. Nitrogen helps to prevent bacteria forming in the bottle, benefitting the fermentation process. The result, “an improvement in the shelf life and quality of the product,” explains Jerry Elsen, General Manager at BOGE America.
The new BOGE EO scroll air compressor range covers the performance segments from 5.5 to 22 kW.
Modular, Compact, Application-Oriented
Up to four air compressors can be installed in a common enclosure to ensure flexible adaptation to the compressed air demand. At 10 bar the EO series can cover delivery rates from 490 l/min to 1,960 l/min, while at 8 bar the supply of compressed air ranges from 620 l/min to 2,480 l/min. Featuring a modular design, the EO series can be ordered with an integrated or separate refrigerated compressed air dryer. It is also available in base or tank mounting.
Flexibility – More Than Just a Catchword
BOGE's control system, focus control 2.0, can regulate up to four EO scroll air compressors horizontally with base load switching, thus ensuring efficient control for as many as 16 air compressor units. And when maintenance is required, users benefit from unrestricted operation of the compressed air system. Durability and efficiency are backed up by a two-stage cooling concept. A primary surface cooler systematically cools down the compressed air along with an aftercooler in stainless steel. The pressure dew point for delta t is approximately 8?K.
