Eco-Lyme descaler is a powerful chemistry with an excellent eco-profile, the company says. This descaler is suitable for use on cooling towers, boilers, processing equipment, evaporative coolers, and more. Eco-Lyme provides performance similar to hydrochloric acid, but is a significantly safer option for technicians and system metals — including stainless steel. The low foaming, odorless chemistry removes scale while restoring system performance and longevity.
