Compact and low maintenance
Narrow widths of approximately 55 in / 140 cm (depending on model) and the resulting small footprint allow for simple transport, as well as ease of relocation and installation in space-restricted machine rooms. A key aspect of the BluAstrum is its minimal maintenance requirements. This benefit is the result of the latest industrial screw compressor technology and design features such as the elimination of an oil pump and the flanged motor-compressor connection on GEA BluAstrum models 400 - 2500. Units are safe and reliable with all-welded construction of both piping and heat exchangers. An optional BluAstrum remote version is provided (with or without a pilot receiver) that can be connected to an external condenser (air-cooled or evaporative) supplied by the customer.
