HVAC condensate pan treatment gel tabs

Nu-Calgon 4185-03 gel tablets prevent slime growth and deposits inside condensate pans while eliminating foul and musty odours. Each red tablet treats systems rated at 3 ton capacity. The tube contains 12 tablets providing up to three months of continuous protection per unit.

Replaces liquid pan treatments

Switching is worthwhile when a maintenance-free solid tablet is preferred over pouring chemicals or scheduling frequent pan flushes. The gel format dissolves slowly for consistent dosing without measuring or spillage.

Verify system tonnage matches the 3 ton rating

Confirm the condensate pan is accessible for tablet placement and that local regulations do not restrict the product. No additional tools or power supply considerations apply to this accessory.

Questions about this item

What size condensate pan does the 3-ton gel tab treat?

The tablet is formulated for air-conditioning systems rated at 3 tons, providing up to three months of slime and odour control per tab.

How do you install the red gel tablet in the drain pan?

Place one tablet directly in the condensate pan; the gel dissolves slowly as water flows over it, releasing treatment continuously.

When should the next tablet be added after the first one?

Each tablet protects for up to three months, so replace it quarterly; a tube contains twelve tablets for a full year of coverage.
