The Hydrex™ tablet prevents drain line and pan blockage in air conditioners, humidifiers, and refrigerators due to buildup of slime and sludge. The a/c tabs give contractors a quick way to keep drain pans and drain lines clean and to control odors. According to the manufacturer, costly water overflow damage can be avoided by a simple dose. The tablets are easily dispensed from the packaged, plastic bottle to control odor and water flow. For treatments, two tablets are used per 1 ton of air conditioning to control odor and sludge for up to 3 months. The a/c tabs are ideal for commercial air conditioning units commonly found in motels, hotels, hospitals, nursing homes, schools, apartments, and office buildings, states the company.
