Nu-Calgon Pan-Treat HVAC condensate pan and humidifier treatment tablets — 200 tablets, biodegradable, non-corrosive

Nu-Calgon Pan-Treat Scum 200 Tablets are dissolvable treatment tablets designed to clean and prevent sludge, scum and odors in HVAC condensate pans and humidifier reservoirs.

Left unchecked, debris and organic deposits in condensate pans and drains lead to foul smells, clogged lines and potential overflows. Nu-Calgon Pan-Treat tablets are a water-soluble, biodegradable formula made to dissolve in condensate drip water so they continuously break down residues and keep drains flowing. The tablets are non-corrosive and non-toxic, making them suitable for routine maintenance in commercial and residential HVAC systems and humidifiers.

How do I use Pan-Treat tablets in a condensate pan?

Place tablets where condensate will regularly drip on them but not directly over the drain to maximize contact time. For an initial cleaning of a fouled pan, use two or more tablets per ton of system capacity and repeat until clean; for ongoing maintenance, one tablet per ton each month is recommended.

• Initial cleaning: 2+ tablets per ton, repeat until clean
• Routine maintenance: 1 tablet per ton monthly
• Position tablets away from drain for best contact with condensate

Can I use Pan-Treat in humidifiers and small systems?

Yes — Pan-Treat tablets condition humidifier water to reduce deposits and odors. For most humidifier reservoirs, add 2–4 tablets every four to six weeks and clean the reservoir regularly to maintain effectiveness.

• Humidifiers: 2–4 tablets every 4–6 weeks as needed
• Smaller systems: follow tablet-per-ton guidance adjusted for capacity
• Rinse and clean reservoirs periodically for best results

Are these tablets safe for equipment and the environment?

Pan-Treat is formulated to be non-corrosive, non-toxic and biodegradable, so it won’t leave damaging residues in pans or drains. Because the tablets dissolve completely in water without forming deposits, they reduce the need for harsh mechanical cleaning or corrosive chemicals.

• Non-corrosive: safe for metal and drain components
• Non-toxic and biodegradable: minimal environmental impact
• Fully water-soluble: no secondary deposits in pans or drains

What maintenance savings can I expect using Pan-Treat?

By preventing scum, sludge and organic build-up, Pan-Treat reduces drain clogs, foul odors and overflow incidents that lead to repairs and downtime. Regular tablet use lowers labor and emergency service costs tied to pan cleaning and water damage mitigation.

• Fewer clogged drains and emergency service calls
• Reduced frequency of manual pan cleanings
• Helps prevent odor complaints and overflow-related repairs
