BOGE EO Series modular scroll compressors

BOGE has re-released its EO series compressors with an expanded power range to 30 kW.

The EO series is designed for sensitive work environments with high demands for oil-free use and process safety in the small to medium output power range. The compressors are available in three sizes for the power ranges from 4 to 7 kW, 11 to 23 kW and 30 kW.

The EO series is characterised by a small footprint, including the version with an integrated dryer. The compressor is also available with a compressed air receiver, as a duplex system as well as with an integrated or external refrigerant dryer. The changes in compressor performance and dimension result in higher efficiency, which is partly explained by the reduction in mechanical losses. Compressor type EO 7, for example, is available with a smaller housing and includes a scroll compressor, while two compressors were integrated in a medium-sized housing in the previous EO 8 type. Two-stage aftercooling provides optimised outlet temperatures. The compressors have been designed for a pressure dewpoint of 3°C.

While two compressors are integrated in the EO 11 and EO 15 types, the EO 23 type has three and the EO 30 type has four compressors that can be individually controlled using focus control 2.0. In this way, the system can be adapted to the application requirements. It also creates redundancies because compressors can be flexibly added or turned off.
