Sammet Stack Dampers utilise a reliable and thoroughly tested technology
with automatic and adjustable pressure relief function, opening the
damper once needed. Stack dampers can be installed in the chimney
itself - or before the chimney in a horisontal duct. Damper installation
position can be either horsiontal or vertical.
Keeping the rainwater out
Sammet has developed a robust and weatherproof design for Stack dampers,
including a rainwater gully collecting rainwater and preventing if
from entering the duct system. A special piping system can be attached
to lead the rainwater out of damper's gully. This function enables
safe and reliable operation in even the severest climate, such as
Arctic Siberia or coastal regions with heavy rainfall.

Preventing unneccessary cooling down
During plant shutdown phases, Sammet Stack Dampers
will serve as energy-savers by preventing heat from running out of
plant via chimney.
