The steam turbine's reliability, versatility and ease of
operation make it an ideal choice to drive equipment required
for many industrial, process oriented and power generation
industries.
Dresser-Rand Inc., USA, ( DR ) is a world leader in designing
and manufacturing single-stage and multi-stage steam turbines.
Drawing on the experience of over 90 years and 80,000 installations
in nearly 100 countries, DR offers unparalleled reliability.
Proven reliability and high efficiency make Dresser-Rand steam
turbines vital partners to the process industries. Energy
conversion costs have demanded that steam turbine efficiency
be as much a consideration as reliability.
