[dropcap]W[/dropcap]hile we didn’t review “coolers” here, we did investigate “coolants” or as they’re technically called, “inserts.”

NOTE: The quality of your cooler greatly affects the performance of any insert.

ArcticIceThere are several brands but only three types of insert coolants – all but one is made from petroleum or alcohol based chemistry. The oil and alcohol based inserts have significantly less impressive staying power with regard to ‘thawing’ than the technology used by Arctic Ice (AI). PureTemp™ is what AI calls its technology – a plant-oil derived “phase-change material” (PCM). AI is completely reusable, non-toxic and biodegradable.

AI has two versions, one is called the Alaskan Series and the other Tundra Series. Within each of those two series of products each comes in small, medium, large and extra large sizes.

The Alaskan Series easily makes the most sense because it only requires a domestic refrigerator to get charged or recharged. The Tundra Series requires a freezer (36 hours) to come up to serviceable reuse. Not everyone has a freezer and if you’re on the road it’s unlikely you’ll find a freezer available for a recharge. An RV with decent refrigeration can do the trick for the Alaskan Series.

A report shows that an unopened Alaskan Series (cooler brand not specified), after 24 hours, held product (product not specified) at 40 degrees Fahrenheit. Local guides here (South Florida) that use the Alaskan Series claim it is almost twice as efficient as petroleum or alcohol base inserts and that it’s much cheaper than buying ice everyday.

Tech Specs Arctic Ice™ Alaskan Series and Arctic Ice™ Tundra Series:

Small – .75lbs – 4.25″x6.25″x1.25″
Medium – 1.5lbs – 6.75″x7.75″x1.25″
Large – 2.5lbs – 7.5″x9.5″x1.25″
Extra Large – 5lbs – 10.925″x8.661″x1.85″

Cooler use suggestions for sizes of both Series’:

Small – Perfect for chilling insulated lunch boxes and mini-coolers.

Medium – Just right for chilling small or mid-sized coolers and insulated tote bags.

Large – Cover the bottom and cargo of your full-sized ice chest with two or more of these large packs to keep it all cold, all day.

Extra Large – Cover the bottom and cargo of your full or Marine-sized ice chest with these to keep it all cool, all day long.
