Why Cleaning Tablets Matter for Your Evaporative Cooler

Evaporative coolers—also known as swamp coolers—offer a cost-effective way to stay cool in dry climates, but like any cooling system, they need regular care to perform at their best. That’s where drop-in tablets for evaporative coolers come in. These simple but powerful cleaning aids help prevent odor, mineral buildup, and algae growth—all without any complicated maintenance routines.

At SwampCoolers.com, we carry EVAP-O-Matic Tablets, one of the most trusted solutions on the market for keeping your swamp cooler clean and operating smoothly.

What Are EVAP-O-Matic Tablets?

EVAP-O-Matic Tablets are drop-in tablets for swamp coolers that dissolve gradually in the cooler’s water reservoir. Each tablet contains a blend of cleaners and scale inhibitors that help maintain internal components and water pads while keeping air output fresh and odor-free.

They’re designed for all major evaporative cooler brands, including PortaCool, Big Ass Fans, Cool Boss, Vector, Cajun Kooling, and more. With no measuring or mixing required, just drop a tablet into your cooler’s reservoir and let it work while your unit runs.

Key Benefits of Swamp Cooler Tablets

• Eliminate Odors: Stops musty, swampy smells from circulating into your space.

• Prevent Scale Buildup: Controls minerals from hard water that can clog pads and lines.

• Control Algae Growth: Reduces the growth of algae in standing water and pads.

• Save Maintenance Time: Extends the life of your cooling media and reduces deep cleaning intervals.

If you’ve ever noticed a foul smell, slowed airflow, or white crusty buildup in your swamp cooler, it’s time to use a drop-in tablet for evaporative coolers.

How to Use EVAP-O-Matic Tablets

Using EVAP-O-Matic is easy. Simply drop one tablet into the water reservoir of your evaporative cooler. The tablet will begin dissolving as water circulates, releasing its cleaning agents slowly and evenly.

Basic usage guideline:

• Use 1 tablet per month for coolers under 5300 CFM

• For units over 5300 CFM, use one additional tablet for every 5300 CFM of airflow

This rule ensures even large units receive proper coverage. For example:

• A 10,000 CFM cooler = 2 tablets per month

• A 16,000 CFM cooler = 3 tablets per month

Common Applications

EVAP-O-Matic Tablets are used across a wide range of environments where swamp coolers operate continuously and need to stay clean:

1. Warehouses

Large industrial spaces often use high-CFM swamp coolers that run for hours daily. Tablets help prevent scale buildup and keep airflow consistent without frequent manual cleaning.

2. Gyms and Fitness Centers

These spaces rely on cool, fresh air—but a smelly swamp cooler can ruin the environment. EVAP-O-Matic keeps air fresh and equipment sanitary.

3. Auto Shops and Garages

Grease, grime, and hard water can make swamp coolers a mess in auto service areas. Tablets help maintain clean circulation in tough environments.

4. Event Spaces and Tents

For short-term cooling at outdoor events, EVAP-O-Matic makes it easier to keep coolers fresh without worrying about odor buildup.

5. Construction Trailers

Coolers in trailers often sit unused between job sites. Tablets help keep internal water systems clean even during downtime.

Why Tablets Are Better Than Liquid Cleaners

Many cooler owners turn to liquid descalers or bleach alternatives to clean their units—but these can be messy and sometimes damage the pads. Tablets are a better solution because they:

• Dissolve slowly for consistent cleaning

• Won’t splash or spill

• Are easier to store and handle

• Won’t over-concentrate or damage cooler components

That’s why swamp cooler tablets have become a go-to for both residential and commercial evaporative cooling.

Safety and Storage Tips

• Store tablets in a cool, dry place away from children and pets.

• Use gloves if handling dissolved tablets directly.

• Do not combine with other chemicals or cleaners in the reservoir.

• Flush the water tank every 4–6 weeks for best results.

EVAP-O-Matic is designed to be safe for cooler components and the environment when used as directed.
