Condensate Pan Gel Tablets for 5-Ton Systems

Nu-Calgon 4185-05 gel tablets treat condensate pans in air-conditioning systems rated up to 5 ton. The blue tablets prevent slime growth and mineral deposits that clog drainage. They also eliminate foul and musty odours caused by standing water. This treatment suits residential and light-commercial HVAC maintenance.

Six-Tablet Tube Delivers Three-Month Cycles

Each tube contains six blue tablets sized at 21 oz for easy handling and placement. Dropping a tablet into the pan requires no tools or measuring. The slow-dissolving gel formulation releases treatment steadily over approximately three months. This reduces the frequency of service visits for pan maintenance.

Verify System Tonnage and Pan Access Before Ordering

Confirm the equipment nameplate shows a 5-ton rating to match the product specification. Ensure the condensate pan is accessible for tablet placement during routine service. Buyers needing treatment for larger-capacity systems or different application methods should seek alternative products.
