I have been working with TMI since 1996 when we installed our first TMI chlorine generator and controller on an indoor pool. We were so impressed with the quality of the equipment, and TMI as a business, that we eventually put their products in all of our facilities. We currently have 24 pools and spas on TMI Systems. TMI also has a great office – friendly and helpful. Tech Support is outstanding. TMI has been specializing in chlorine generation and pool automation for more than 20 years. They really know their stuff.
