Abstract
A fluid compression system is disclosed having a hermetically-sealed housing with at least a motor and a compressor arranged therein. The motor may drive both the compressor and a blower device coupled to the housing or otherwise arranged within the housing and configured to circulate a cooling gas throughout the housing and thereby cool the motor and accompanying radial bearings. The blower device circulates the cooling gas through a closed-loop circuit which may include a heat exchanger and gas conditioning skid. Buffer seals may be used to seal the shaft on both sides of the compressor so as to prevent the migration of liquid and solid contaminants into the closed-loop cooling circuit.
