These are water treatment tablets for evaporative cooling fan reservoirs — they keep slime, scale, and odor-causing microorganisms from building up on your cooler pads so the system runs cleaner and needs less maintenance.
Evap-O-Matic tablets are a maintenance product for evaporative (swamp) cooling systems, not refrigerant-based mini-splits or PTACs. If your PolarCool unit runs pads and a water reservoir, buildup on those pads and the odors that come from stagnant water are a recurring maintenance headache — these tablets are built to address both at the source. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.

FAQ
What does Evap-O-Matic actually do inside the cooler?
It's a slow-dissolving, self-metering tablet added to the evaporative cooler reservoir. It inhibits slime and scale buildup on the cooling pads and controls odor-causing microorganisms.
How many tablets come in a jar, and how many jars are in a case?
A single jar contains 12 tablets (SKU 0503-1020). A case contains 12 jars, or 144 tablets total (SKU 0503-1021).
Will these tablets leave deposits or residue in the reservoir?
No. The tablets are completely water-soluble and do not form deposits in the reservoir.
Is this the same product used in refrigerant-side condensate lines on mini-splits?
No. Evap-O-Matic is formulated for evaporative cooling fan water reservoirs only. It is not intended for mini-split or PTAC condensate systems.
