This AERCO condensate neutralizer kit has a capacity of two liters. The kit's purpose is to neutralize acidic condensate, a byproduct of gas-fired boilers and water heaters. It includes a cylindrical container filled with marble chips that act as the neutralizing agent. As the acidic condensate flows through the marble chips, it undergoes a chemical reaction that reduces its acidity, making it safer for disposal into public sewer systems. The kit also features an easy-to-install design and can be attached directly to the heating or water system. It's recommended for use with high-efficiency appliances that produce condensate with pH levels below 7. Each two-capsule model (part number 89025-2) will neutralize condensate from appliances up to 1,000,000 BTU/hr input. Part number 89025-2 includes a 2 liter (0.53 U.S. gallon) capsule made from corrosion-resistant materials with two 3" fill/access openings, 3/4"-14NPT threaded inlet, 3/4"-14NPT threaded outlet, three 3/4" NPT to 1/2" hose barb fittings, 1/2" barbed Y fitting, six hose clamps, 10 ft of 1/2" ID vinyl tubing, two base/wall mounting clamps.
