DISC DAMPERS - Sammet Industrial Dampers

SAMMET DAMPERS OY
Introducing
The Ultimate
Damper Series
Sammet offers a wide range of
dampers for a variety of applications,
including regulating, isolating, diverter,
safety, guillotine, sealing air, and heatresistant
dampers. The Sammet Disc
Damper is designed to isolate dustladen
gases in pulp and cement
production, metallurgical processes,
and oil-fired and coal-fired power
plants. These units are often used
before and after electrostatic
precipitators, and enable personnel to
service an ESP without unnecessary
stoppages.
Sammet delivered its first disc dampers
during the 1980s, and since then has
evolved into a front-line partner for
major boiler and gas cleaning system
manufacturers, with hundreds of units
installed in countries such as India,
Portugal, Russia, Sweden, China,
Finland and Indonesia.
How does it work?
Sammet Disc Dampers incorporate a
number of unique features – many of
which are patented – to provide
maximum performance and reliability,
safe operations, and easy maintenance.
In basic terms, a Sammet Disc Damper
consists of a casing, a disc, and an
actuator. Throttling is negligible when
the damper is open, as the disc is
raised against the wall of the valve
casing. This means that pressure drops
are low, and ensures efficient utilisation
of damper capacity. Raising the disc in
this way also protects the actuating
mechanism from fouling and wear
caused by dust-laden gas.
Sammet Disc Dampers occupy very
little space outside ducts and can be
easily incorporated into existing ducting
using a simple flange connection.
Standard units are available for
rectangular ducts, as well as circular
and custom sizes. Customers can
select from electric, pneumatic,
hydraulic, and manual actuator options.
The manufacturing process of
disc dampers requires exceptionally
high expertise and continuous
quality control.
Sammet makes a great effort to
ensure the first-class quality and
faultless function of every product
leaving the factory by careful and
systematic quality control,
numerous tests and test drives
before delivery.
Flow calculation is an
important part of
Disc Damper engineering.
