Acid Plant Dampers


This range of dampers is designed specifically for applications with process gases containing SO2 or SO3, for those applications that require ZERO LEAKAGE to the atmosphere to protect both the environment and the safety of plant personnel.

Special shaft seals with purged lantern ring and labyrinth arrangement guarantees the Zero leakage of process gas to the atmosphere.

The dampers can be butterfly or louvre type, manufactured in corrosion resistance material such as ASTM A36, AISI 304H, Alloy 31 or C276.

 DTL can provide PED Compliance (as appropriate) for high pressure applications.
