NuvoH2O Evaporative Cooler Scale Preventer Puck — 3-Month Limescale Protection for Swamp Coolers
NuvoH2O Evaporative Cooler Scale Preventer Puck — 3-Month Limescale Protection
Hard water limescale is the #1 enemy of evaporative coolers (swamp coolers). Scale accumulates on the water pan, pump, pads, and distribution tubes with every cooling cycle — reducing efficiency, restricting water flow, and causing premature component failure. The NuvoH2O Evaporative Cooler Scale Preventer Puck stops this damage with a dual-action citrus + polyphosphate formula that removes existing limescale and prevents new buildup for up to 3 months .
Dead simple to use: place the puck in the water pan away from the pump and replace every 3 months. That's it.
Dual-Action Formula: Citrus Boost + Polyphosphate Protection
Citrus Boost (CitraCharge®): The natural citrus formula actively dissolves and removes existing limescale buildup from the water pan, pump housing, pads, and distribution tubes — restoring water flow and cooling efficiency.
Polyphosphate Slow-Release Pearls: Polyphosphate binds to hard water minerals (Calcium and Magnesium) in the water pan, keeping them suspended and preventing them from depositing as scale on cooler components throughout the full 3-month lifespan of the puck.
Key Features & Benefits
Prevents limescale buildup on water pan, pump, pads & distribution tubes
Removes existing limescale — restores water flow and cooling efficiency
Dual-action formula: citrus descaling + polyphosphate scale prevention
Lasts up to 3 months per puck — no measuring or daily maintenance
Simple placement: set in water pan away from pump
Extends the life of evaporative cooler components
Reduces maintenance costs and service calls
Proudly made in the USA
How to Use
Place the puck in the evaporative cooler water pan, away from the pump .
Run the cooler as normal — the puck slowly releases its dual-action formula with every cycle.
Replace after approximately 3 months or when the puck is fully dissolved.
Why Limescale Destroys Evaporative Coolers
Evaporative coolers are especially vulnerable to hard water damage because they continuously circulate and evaporate water — concentrating minerals with every cycle. Scale accumulates rapidly on:
Water Pan: Scale buildup reduces water capacity and harbors bacteria
Pump: Mineral deposits strain the pump motor and clog the inlet, leading to failure
Cooling Pads: Scale clogs pad media, reducing airflow and evaporative efficiency
Distribution Tubes: Mineral deposits block the small holes, causing uneven water distribution and dry spots on pads
The NuvoH2O Scale Preventer Puck stops this damage before it starts — and dissolves scale that's already there.
