Nu-Calgon PurCool Green Mini Strips condensate pan treatment — 1-pack, time-release, up to 6-month protection

Nu-Calgon 61044 PurCool Green Strips are time-release condensate pan strips formulated to cling to pans, dissolve gradually, and help keep pan drains clear for systems up to 5 tons.

These compact PurCool Green (PCG5MS) mini strips are designed for use inside air handler condensate pans to slow biological growth and reduce clogs. Their plant-based suspension and dispersing components allow the strip to adhere to the pan surface and release active ingredients over time without a removable sock or housing. Because they dissolve as they work, there’s no need to retrieve a cartridge at service intervals—just replace with a new strip when life is up.

How long will one Nu-Calgon PurCool Green strip last in my condensate pan?

Under typical operating conditions, a single PurCool Green mini strip is formulated to provide protection for up to six months. Actual longevity depends on system runtime, humidity, and biological load in the drain pan.

• Rated life: up to 6 months under normal use
• Best for systems serving up to 5 tons
• Replace sooner in high-microbial or heavy-duty commercial settings

How do these strips reduce pan overflows and clogs?

The time-release chemistry helps limit slime, algae and biofilm that commonly build in condensate pans and block drains. As the strip dissolves, ingredients disperse across the pan surface to keep water flowing toward the drain rather than pooling.

• Adheres directly to the pan for continuous release
• Plant-based suspending agents improve distribution
• No separate housing or sock required—fully dissolves

Are these strips compatible with my existing equipment and part numbers?

Nu-Calgon PurCool Green mini strips are compatible as a replacement for multiple legacy part numbers and commonly used pan strip products. They’re intended for placement in condensate pans of air handlers and similar HVAC equipment.

• Suitable for systems up to 5 tons
• Compatible replacement for part numbers like 61044, PCG5MS, PCGMS, and others
• Works with ClenAir and many Pan strip brands where a dissolving strip is used

How should I install and monitor the PurCool Green mini strip?

Installation is straightforward: place the strip on a clean area of the condensate pan where water flows, ensuring it will remain wet during operation. Periodically verify the strip is dissolving and check the drain for steady flow; replace at the end of rated life or sooner if heavily soiled.

• Place flat on pan surface in wet zone for consistent dissolution
• Inspect every service visit and replace as needed
• No housing removal needed—simply add a new strip when required

Who is this for: Nu-Calgon 61044 PurCool Green Strips are intended for HVAC technicians, building maintenance teams, and homeowners who want a low-effort, time-release solution to control biological buildup in condensate pans of small to medium air handlers (up to 5 tons). They’re especially useful where frequent access is inconvenient and a dissolving strip that leaves no removable housing is preferred. Note that performance varies with system conditions; follow regular maintenance practices and replace strips based on observed performance or the suggested service interval.
