CTS1 Mechanical shoe plate seal

The CTS1 is a well-designed shoe plate seal, eliminating all the problems traditional shoe plate seals have generated in earlier generations of seal design. Its design is based on shoe plates being pressed firmly to the tank shell by compression plates backing up these shoe plates. The pressure point is in the centre of gravity of each shoe plate, therefore securing the full height of each shoe plate contacts the tank shell. As the seal design has no moving parts it will not encounter problems as a result of corrosion or waxy product sticking in sliding or pivoting seal mechanisms. Each CTS1 seal will be individually engineered and manufactured to fit the tank involved, making sure the seal will be able to deal with both the stored product as well as with the particular dimensional properties and design aspects of this tank.

CTS1 Product Features:
- excellent vapour tightness, resulting in maximum emission reductions
- eliminating much of the rain water ingress to the product stored
- compatible with all stored products , including 100% aromatics
- available in different material combinations, including galvanized steel and
  stainless steel
- suitable for both vertical and horizontal roof rims
- no rim modifications necessary
- expected service life in excess of 30 years
- designed for each specific tank
- maintenance free
- easy installation
- full installation manuals and project support available
- complies with EPA standards
- successfully used globally by many major oil and tank storage companies
- can be used with both welded and rivetted tank shells
- can be combined with all known secondary seal designs
- liquid mounted seal

Design and engineering
CTS designs each individual seal for the tank it will be fitted on. This will prevent the installation of a standard seal, where it is possible to find out within months that this standard seal would not be able to deal with the actual rim gap or tank conditions.
A detailed tank inspection sheet will facilitate our engineering process. Delivery will include an as-built drawing for the supplied tank seal as well

Installation
CTS is capable of installing any seal on your tank, but our extensive drawings and installation manuals will facilitate you to have either your own or contractor staff install the seal and, if applicable, the integral foam dam as well. The advantage of having your own (contractor) staff installing the system could be significant, reducing travelling and lodging costs. Experienced CTS supervision is available upon request.

Materials, selection
Not just the design of the seal is important for its performance. Correct material selection might be even more important to ensure a long term adequate performance for any seal. In this respect one also has to realise that fabrics will be difficult to inspect and malfunctioning seals could represent a hazard, while still mechanically sound. Materials have to withstand the stored product, ozone, sun exposure and rain water contact. CTS is able to give you a profound advise on the optimal combination of materials, resulting in an economic seal design able to deal with the harshest conditions. Seals can be manufactured in a wide variety of materials, including different grades of stainless steel and polymer materials. This will make our seals suitable for processes with 100% aromatics or aggressive chemicals.
