Testimonials

  • “Indeed it is a nice association with OTSIL. One of recent experience has been excellent by providing very good support on Technical aspects by installing Pilot Plant to run the Ozonator in actual site conditions. This is to analyse the Results in Germany that helped our customer to narrow down option to go ahead with Ozonator of OTSIL make against other Imported Technology and helped Make in India. The Technical and service support is very good so far.
    If anyone wants an Ozonator, it is worth giving OTSIL a try, which can give solutions and meet the highest standards (of companies like Ion Exchange).”
