MRS-20S Secondary Compression Plate Seal

Our MRS-20S Secondary Compression Plate Seal a vapor or vapour mounted rim seals on an external floating roof consists of a continuous seal mounted on the rim of the floating roof and extending to the tank wall, covering the entire primary seal. These secondary seals are normally constructed with a flexible polymeric material, where the design incorporates steel leaf’s to bridge the gap between the roof and the tank wall. The leaf’s acts as a compression plate to hold a polymeric wiper against the tank wall.

Our Floating Roof Rim Seals are custom designed to each individual tank within the requirements of API 650/653, BS 2654, EN-14.015 and EEMUA-159.

MGL Projects has combined over 20 years’ experiences from the past with their research and development, through which it has produced increasingly innovative products for reducing above ground storage tank (AST) emissions. And it’s not just about the new and interesting, when old technologies and products are to be revitalised or re-used it always can be reviewed and when needed altered to be made more efficient.

Models

The most commonly used Vapor Mounted Seals or vapour mounted seals either used as a single or combined configuration are:

• MRS-20P Primary Compression Plate Seal

All Maxwell EFR Rim Seals can be combined with;

• MRS-20S Secondary Compression Plate Seal
• MRS-25 Weather Shield

Finally, when the local requirements are pushing local terminals or refineries to add a tertiary or triple rim seal, on request these extra rim seals can be provided.
