In addition, this closed loop serves as a full scale endurance test apparatus. Problems in design, should they arise, are addressed here before any equipment is placed in the field. VIP Installed in the Dresser-Rand Rental Fleet. Successful testing using both lab endurance testing combined with field testing equates to a more reliable compressor when it is sold to our clients. This can be seen in the preceding figures.
Fewer parts means lower cost.
In addition, a part commonality between cylinder bore sizes is a plus when considering some inventory for common wearing or replacement parts. This design therefore has an overall effect of lower installed cost due to fewer parts and lower long term operating costs because of parts commonality. One of the main concerns is the reliability of high-speed compression equipment. Dresser-Rand sought to develop a compressor to address this concern. Successful designs, laboratory testing, and field testing provide a sound basis on which to introduce a new compressor to market.
