Dresser-Rand offers the industry a complete
line of process reciprocating compressors—eleven models, 5 to 45,000 HP, pressures from vacuum to 60,000 psi. Our products
reflect 250 years of combined experience from the names you trust:
Ingersoll-Rand, Worthington, Dresser-Clark. No other manufacturer offers
such a wide variety of machines to handle most applications. From such a
wide selection, the process engineer can readily choose the compressor
that best fits your needs exactly. Highly versatile compressor designs are
available for single, multi-stage or multi-service compression
applications, from one to ten compressor cylinders. Dresser-Rand
compressors include:
- HHE
and BDC models from 200 to 45,000 horsepower (149 to 33,557 kW)
- ESH, HSE
and PHE models up to 1,000 BHP horsepower (746 kW)
 Precision Construction
Every part, from crosshead to crankcase, from
bearings to crankshaft, is precision made to exact tolerances. Dresser-Rand
reciprocating compressors are designed for easy maintenance. All moving
parts are readily accessible through convenient, oil tight covers. The
crosshead on larger frame sizes (HHE and BDC) has been designed to eliminate
the threaded connection between the piston rod and crosshead. A flanged
crosshead design with hydraulically-tensioned studs is used on 3.5"
piston rods and larger. Hydraulic tensioning is standard on all frame and
cylinder bolting 1-5/8" and larger.
Reliability
Dresser-Rand reciprocating compressors have
established an outstanding record for endurance, dependability and
versatility. That’s why more than 28,000 rugged compressors and engines have
distinguished themselves around the world. Based on proven design
principles, they have set the pace in all types of process applications.
 Compressor Applications
The HHE and BDC compressors are
exceptionally suited to the very largest applications, which require maximum
gas handling capabilities at high operating or differential pressures.
Typical applications include hydrocracking, hydrotreating and
desulfurization refinery processes; natural gas processing and high pressure
injection; chemical and refrigeration processes; enhanced oil recovery;
natural gas, ethylene, carbon dioxide and oxygen pipelines; and ammonia,
urea and polyethylene production. Shown here is a 13,000 horsepower HHE-VL
hydrogen compressor.
 The ESH, HSE and PHE compressors are
exceptionally suited to the smaller applications, which require compact,
simple and speedy installation. A skid-mounted HSE package is shown here.
These compressors perform reliably in a variety of difficult process
applications including ammonia, butadiene, butane, carbon dioxide, chlorine,
hydrogen, hydrogen sulfide, methane, bone dry nitrogen, pentane, phosgene,
propylene, sulfur dioxide, and vinyl chloride.
 Compressor Cylinders
Dresser-Rand’s modern cylinder lineup is
based on the latest cylinder design technology. Our heavy process (HHE and
BDC) cylinder designs shown here have been analyzed using FEA and strain
gauge tested to prove the FEA model while selected cylinders were
successfully burst tested. All cylinders within a rod load class have a
common distance piece bolt circle so that only one distance piece design is
required. New distance pieces have external bolting for easier maintenance.
Process cylinders are designed with full water jackets around the cylinder
bore. Efficient water jackets keep the cylinder bore walls cool for maximum
ring life, especially important for non-lube applications, and also
dissipate heat during unloaded operation.
 Capacity Control
Dresser-Rand has three types of capacity
control devices, which can be selected to best suit your application. Plug,
port and plunger type unloaders are used to unload one or more cylinder ends
for starting or for capacity control. Clearance pocket unloaders are used
for alternate gases or for alternate design flow conditions. They may be
used in combination with plug, port or plunger type unloaders for maximum
flexibility in process control and minimum waste of power caused by
bypassing. Clearance pocket unloaders are of the same design as port
unloaders.
 Compressor Valves
Valves are the most critical component in
compressor reliability. Our continuous research and development has produced
a new generation of efficient and highly reliable valves with new technology
materials. Dresser-Rand applied more than a century of design and
manufacturing experience to create the MagnumTM valve shown here
and make it compatible with all brands of reciprocating compressors and an
extensive range of operating conditions and gas processes. Since its release
to the market, more than 20,000 MagnumTM valves are operating
successfully in lubricated and non-lubricated service, with gases ranging in
molecular weight from 2 to 71, speeds from 327 to 1,000 RPM and discharge
pressures ranging from 35 to 4,000 psig.
Dresser-Rand’s proprietary dynamic valve
analysis (DVA) computer program is used to analyze full and part-load
operating conditions to maximize valve reliability while minimizing
horsepower and capacity losses.
Compressor Wear Parts
Dresser-Rand now offers a complete line of
DuraWearTM performance parts for reciprocating compressors,
including piston rings, rider rings, and rod packing rings available for
both lubricated and non-lubricated applications, for pressures up to 11,000
psi, for temperatures up to 395ºF, and for clean/dry, wet/dirty, or
corrosive applications.
Engineering Capabilities
At Dresser-Rand, comprehensive engineering
and careful workmanship based on more than 250 years of compressor building
experience make the difference. Dresser-Rand engineer’s combine proven
design features with new refinements and developments to provide the most
modern process and gas field compressors in the world. Our in-house
metallurgical laboratory for process quality control, materials review and
component analysis ensures consistent, repeatable performance. For each
compression system, Dresser-Rand can digitally analyze piping for resonance
and vibration, and then design the required pulsation dampeners.
Representing the ultimate in design, material and construction, our machines
are built to meet today’s and tomorrow’s processing needs.
 Product Reapplication
With over 2.5 million OEM detailed drawings,
material specifications and design criteria, Dresser-Rand is the best source
for engineering to reapply, revamp or upgrade existing equipment. At the
same time, we engineer the latest Dresser-Rand product developments into
your reapplication. You’re also supported by our global manufacturing and
service center operations.
