Obtain effective scale control without the use of chemicals! Electric H2O, Inc. manufactures the patented ED 2000 Electronic Anti-Fouling System. The ED 2000 treats water before it enters heat transfer equipment, pumps, spray nozzles, etc. where scale is likely to form. The unit precipitates dissolved mineral ions into large insoluble crystals so that scale does not adhere to surfaces. The technology was developed by a professor of Mechanical Engineering at a large US university and has been used effectively for over 10 years. The ED 2000 PLUS is also now available which protects against scale, biofouling and corrosion in cooling systems!
