Summary of Advantages

• Lower lifetime cost, i.e. Capital plus Maintenance
• EVAPOSTOP can have a payback period of less than a year and will continue to yield savings of thousands of dollars annually
• EVAPOSTOP discs are completely maintenance froe
• Due to their unique geometric design, the discs automatically seek the maximum surface coverage, thus minimizing the evaporation rate
• No hat work (welding work) required for installation
• Minor modifications may be required to existing tank fittings and instrumentation
• Minimal tank downtime during installation (1 day vs. several weeks)
• Flexible use – discs can be reused for different applications, or in tanks with different diameters
• No risk of unbalancing, jamming or sinking commonly associated with internal floating roofs due to most fixed roof tanks not being completely round
• No recalibrating or restrapping of tanks required
• Reduces fire case by reducing evaporation and fueling of fire
• Tank working volume maximized – tank can be run with higher maximum and lower minimum levels, compared to internal floating roof tanks. Typically, an internal floating roof tank will require a 1m clearance at both the top and bottom of the tank.

No incendive sparks caused by EVAPOSTOP disc (as opposed to internal floating roofs). There is therefore a much lower risk of internal explosions or fires occurring.
