I’ve had several people ask me how long ice lasts in a typical soft-sided cooler when using the Blowbox. Since I had absolutely no idea, I went outside yesterday with my new Coleman 40 can cooler and a Blowbox to find out. Here’s a quick video:
Anyone who’s personally seen or built a Frankencooler knows how well this design works. Building one isn’t that difficult, but the ease of building and the ultimate effectiveness of the cooler can vary significantly depending on the components chosen. Cheap blowers that pull high amps will quickly deplete a battery. A motor controller that’s rated too low for the total load won’t last. The majority of marine pumps are bad choices for battery power. Most common-shaped heat exchangers are a pain to mount and difficult to seal. Choosing the right ice chest can by itself easily halve the time it takes to build a Frankencooler.
For over four years I have continuously tried new components in an effort to find the best mix of performance, ease of installation, and cost (you should see my inventory of stuff that didn’t cut it). Thanks to new wholesale accounts and large-scale purchasing, I am pleased to announce that I am now able to offer $$$ high quality, squared, easy-to-mount heat exchangers with threaded. solid brass 90-degree swivel fittings in all of my major component packages at no additional cost. In addition, I am now including intake heat exchangers like the one featured in my grey and orange ‘Ultimate Frankencooler’ in place of the large and cumbersome automotive heater core units : )
To kick off the summer, I have also re-instituted free UPS shipping for all component packages.
Thanks to everyone who has built their own Frankencooler and spread the word that these hideous looking contraptions outperform every other ice-fueled cooler on the planet, regardless of cost. Your word-of-mouth has made Frankencooler a success, and I sincerely appreciate it.
