Innovative design and superior components give DATUM compressors that competitive edge.
From initial concept, through consultations with our clients, to design and production, our goal with the DATUM line was to produce a better centrifugal compressor with an eye toward the environment. This has led to a number of client benefits:
Improved Efficiencies:
Depending on application requirements and configuration, DATUM compressors often operate at efficiencies that are two to five percent greater than competitive turbomachinery, thereby reducing fuel consumption or increasing throughput per installed horsepower. In addition, the improved aerodynamic design and larger shaft diameter enable DATUM compressors to handle greater flows and pressure rations than standard designs for a given frame size. In some cases, a single DATUM compressor can deliver pressure ratios that previously required multiple bodies.Reduced Emissions:
The superior efficiency of the DATUM compressor reduces driver fuel consumption, which can result in a decrease in harmful CO2 and NOX emissions - more important than ever as environmental regulations tighten. Dresser-Rand is committed to addressing critical environmental concerns while continuing to improve operational efficiencies. Incorporating D-R dry gas seals further reduces emissions by eliminating the need for processing sour seal oil.Reduced Noise:
The most significant development in our efforts to design quieter machines has been the introduction of D-R duct resonator arrays. This patented feature is internal and can be designed into new equipment and revamps, including non-Dresser-Rand equipment.Easier, Faster Maintenance:
Even a single lost day of production can translate into losses of hundreds of thousands of dollars, so we made easy maintenance a priority throughout the design process. One way we dramatically reduced maintenance time was by combining the rotor, diaphragms, and other stationary flowpath components, bearings, seals, and instruments - almost everything but the casing - into a module. This module can be completely pre-assembled outside of the casing, then installed as a complete assembly. Critical dimensions, fits, and clearances can be checked much more easily. By storing a spare module on sie, turnaround times can be reduced to a few hours.Standardization:
To improve reliability and reduce cost, we standardized DATUM compressor components wherever possible, maximizing the use of proven designs. The DATUM line consists of 15 standard frames sizes that are scaled from the median size frame. The impellers, diaphragms, inlets, volutes, and shafts are all directly scaled. The bearings and seals are not directly sealed, in order to take advantage of outside vendors' standard sizes. Further standardization was achieved by using the same internal components in both the radially and axially split versions.
