Isomembrane© Testimonials:These are samples from just the Midwest but we have hundreds nationally.

• Dynegy– “We used Isomembrane© on the SH Outlet and Sidewall seals in the penthouse and can

attribute a gain of 3-4 MW’s as a result.” Plant Manager

• Michigan South Central Power– “We installed Isomembrane© in our penthouse on the Sidewall Seals and SH Inlet

Pendants and eliminated a 20 year old fly ash problem. It lowered our down time to access the penthouse for inspections and maintenance work as well as eliminated the cost for fly ash removal. We also like the rugged look of the Isomembrane© seals on the Expansion Joints, they last longer than the conventional expansion joints we replaced” Plant Engineer

• KCP&L– “We went with the Isomembrane© seals on our Economizer Expansion Joints and could see

a 10 MW increase just from the partial seals as LTT technicians installed the seals on line, it got too hot for them to work on top so they had to come back to finish the job, on short notice during a weekend forced outage” Plant Maintenance & Engineering

• Duke Energy– “LTT has mobilized several times in less than a 24 hour period to keep us running by

installing partial Isomembrane© Seals on our Precipitator Outlet Expansion Joints that work great”. Plant Engineering

• Midwest Generation– “We are very pleased with the Isomembrane© repair on the precipitator and the results we

have received on fan capacity due to the Isomembrane© application. We are able to run the unit at full load, without de-ratings due to fan.” Project Manager
