Dresser-Rand Offers Most Comprehensive Steam Turbine Line in the Energy Industry
In September 2005, Dresser-Rand acquired
assets of Tuthill Energy Systems, which
include the Coppus, Murray and Nadrowski
product lines, expanding Dresser-Rand’s
steam turbine line of single- and multi-stage
steam turbines.
Dresser-Rand maintains one of the
largest installed bases in the industry. The
assimilation of the Coppus, Murray and
Nadrowski brands into the Dresser-Rand
family provides clients with the most
comprehensive steam turbine offering
in the industry – backed by a worldwide
network of sales, manufacturing and service
support for all Dresser-Rand steam turbines
– Coppus, Dresser-Rand, Moore, Murray,
Nadrowski, Terry, Turbodyne, and
Worthington.
had developed the first gas compressor
driven by a gas engine. Building upon this
legacy were Murray, Terry, Coppus and
Nadrowski steam turbines in the early 1900s;
Moore steam turbines in 1916, which later
became Worthington and then Turbodyne in
the 1970s; and Dresser-Rand steam turbines
in the 1980s.

History
Dresser-Rand has more units in the field
than anyone else, with roots that date back to
1840 when Henry R. Worthington designed
and built the first direct-acting steam pump.
Other innovations followed and by the early
1900s the company Worthington founded

What makes Dresser-Rand the best choice
for service? D-R has many ways to help
clients get the most from their equipment
As the OEM, Dresser-Rand has access
to the original design specifications,
equipment drawings, service records
and other engineering data for thousands
of steam turbine units with D-R and its
legacy nameplates. D-R knows how all
components work together and understands
the implications of any changes.
When clients get replacement parts from
Dresser-Rand, they are getting the most
modern materials and the latest design
updates – all backed by OEM expertise.
Our OEM replacement parts include the
most advanced materials to minimize
downtime and maximize mean time between
overhauls. In addition to custom stocking

Dresser-Rand offers a vast array of stateof-the-art upgrades and modernizations.
The latest design and manufacturing
improvements, as well as D-R’s extensive
engineering knowledge and field operating
experience, provide components that
maximize safety, increase performance
and availability, extend equipment life and
reduce life cycle costs.
A change in operating requirements doesn’t
always have to mean new equipment. D-R’s
full range of engineering services, including
feasibility, performance, and torsional
studies, as well as SAFE analyses on turbine
blades, means D-R can often meet clients
needs by fully evaluating and implementing
the necessary changes to their existing
equipment. This cost-effective alternative
can increase the current unit’s reliability,
availability and performance.
Steam turbine owners have another option—
a Dresser-Rand Restored Classic. This is a
previously owned steam turbine that D-R
has upgraded to our current specifications,
completely reconditioned and reengineered
for specific applications. Restored Classic
steam turbines include a new warranty.
Technology
D-R is a technology leader, committed to
R&D in helping clients determine the best
solutions for their equipment and operating
needs.
Advances in steam-flow-path aerodynamics
and thermodynamics, combined with
improved materials and manufacturing

processes, have made it possible to improve
steam turbine performance with simple
component upgrades – even if the units
are operating at or close to their original
specifications. In the past 20 years, DresserRand has improved the overall efficiency of
its steam turbines by nearly 10 percent. D-R
has maintained its commitment to R&D with
substantial investments in several key areas.
Dresser-Rand
and recommended spares programs, we
stock a large inventory of replacement parts
in warehouses throughout the world, ready
to ship at a moment’s notice.
For example, D-R has developed nozzle
ring and diaphragm construction techniques
that yield significant improvements
compared to previous methods. DresserRand uses an innovative profiled ring and
vane (PRV) process to construct nozzle
rings and diaphragms. PRV diaphragms,
with their special end-wall profiling, offer
greater efficiency compared to conventional
diaphragm designs.
Dresser-Rand’s retractable labyrinth seal
design for interstage shaft sealing on large
steam turbines increases reliability and
maintains long-term efficiency.
Adequate sealing of bearing cases, in order
to limit the accumulation of water in the
lubricating oil, is a concern to all steam
turbine operators. In order to improve
bearing sealing, Dresser-Rand provides an
oil sealing system that incorporates a PTFE
carbon ring fitted into a special labyrinth.
This oil sealing system is also available as
an upgrade for most Dresser-Rand standard
product single-stage units.
