I wanted to thank you for fixing the 9' diameter Nutshell U.S. Filter that was not functioning at our plant in Venezuela. this filter has been malfunctioning for over 5 years and we had done everything that the manufacturer had asked us to do to make it work adequately and to give us the desired output. We had their technician to our site several times and the filter would operate normally for a day or less and go down again.
   We were very frustrated by this until we were able to locate you. Your experience and quick response to our problem is to be commended. We had many here who doubted that after such a dismal past this filter would ever become valuable to our operations. You proved them wrong by fixing our filter at a very reasonable price.
   I would recommend you to anyone considering a nutshell filter application.
