The MiniCooler

The Original MiniCooler

Upgraded for 2027: Available Soon

The MiniCooler is a compact solar-powered evaporative cooler designed for small enclosed spaces where traditional AC isn't an option. It delivers 500 CFM of cooled air while drawing only 30 watts — making it one of the most efficient off-grid cooling solutions available.

Built for greenhouses, sheds, small cabins, and animal enclosures, the MiniCooler uses high-density evaporative media to pull heat out of the air as water evaporates through the pad. A 1/4-inch float valve keeps the water reservoir full automatically — just connect a garden hose or water line and it maintains itself.

The MiniCooler runs on 12V DC power, so it pairs directly with a small solar panel (30W or larger) for zero-cost cooling during the hottest part of the day. No grid connection, no expensive wiring, no high-voltage risk around water and moisture.

Key Features:

• 500 CFM cooled airflow — ideal for spaces up to 200 sq ft
• 30W power draw — runs on a single 30W+ solar panel
• 12V DC brushless motor — quiet, long-lasting, energy-efficient
• High-density evaporative media — replaceable, long-life cooling pads
• 1/4-inch float valve — automatic water fill, no daily refilling
• Wall-mount design — 11-inch rough opening, compact footprint
• Plug-and-play 2.1 x 5.5mm DC connector — simple solar or battery hookup

Ideal for:

• Small greenhouses and hoop houses
• Garden sheds and workshops
• Animal shelters and chicken coops
• Off-grid cabins and tiny homes
• Portable cooling for camping or events

The MiniCooler is the original Western Harmonics evaporative cooler — now upgraded for 2027 with increased airflow and a more efficient motor. Available soon.
