Extreme Temperature Test

Testing my ice chest air conditioner on a hot, humid day over a period of 7 hours.

Notes: The cooler was holding 35 lbs of ice ( 3- 10lb blocks, 5lbs of cubes) and one gallon of water. No freezer bags were used which would have extended ice melt duration.
The actual outdoor temperature in the shade according to my infrared thermometer was 105 degrees (temp sensor under intake grill was in direct sun for a period, indicating 111). Humidity was 70% average.
The cooler was not moved or opened during the test. The camera was removed from the tripod and brought inside between takes.

I receive a lot of emails asking questions about my coolers so I have created a FAQ section at the top of the right column addressing many of the most common. If you don’t see an answer to your question, contact me at frankencoolerusa@gmail.com.

Ultra Compact Cooler AC

After hearing from golfers and pilots seeking an even smaller ice ac unit, I recently completed this smaller version of the Blowbox(TM).

Still utilizing multiple heat exchangers, powerful 4″ blower, marine pump, and variable-speed motor controller, this unit delivers the same cooling as its bigger brother, only in a smaller, lighter package (5.84 lbs. plus 1 lb for pump assy.)

Anyone can build this unit with our Blowbox component package by requesting this enclosure instead of the larger one.
