Phase Change


Capable  of  storing  and  releasing  large  amounts  of  cooling  potential  within  the  same  temperature  ranges  as  typical  refrigerators,  freezers,  and deep-freezers.


42° F  /  5.5° C

Freezes Solid at Fridge Temp

Maintains a precise temperature range of  36° F to 46° F  (2°C to 8°C)  which prevents contents from freezing or getting too warm.

Protects medications, vaccines or sensitive food and beverages like chocolate and wine.

Extended cooling for packaging prolongs the chill for aluminum beverage cans and bag-in-box applications.

Automatically kicks in when removed from the fridge to give 30 minutes to over 1.5 hours of additional cooling with no insulation or ice required.

The Most Eco-Friendly Drain Safe Ice

Enviro Ice™ is a +32°F formulation that is 100% drain safe.  Powered by Frosty Tech™ and manufactured by Pelton Shepherd Industries, it contains Nitrogen based ingredients that allow it to be used as plant food, which enhances foliage growth and give plants the energy to grow and produce at an increased level. Pour the gel straight into the soil of indoor or outdoor plants.  This eliminates the massive amount of wasteful disposal caused by gel packs every year.

Freezer Temperature

Super fast chilling for beverages. Cool down beverages from ambient to under 45°F (7.2°C) in just minutes.

Maintains cold for hours. Products include Coozies, Shaker Bottles, and Pitchers.  

When frozen, Frosty Tech™ material separates out into interlocked salt and ice crystals.

When it's taken out of the freezer and starting to melt, these crystals re-mix and produce super-cold temperatures that are like typical freezer gels on overdrive!

Deep-Freeze Dry Ice Replacement

Replaces dry ice for 1 - 2 day shipments and in some cases as long as 72 hours.  Resolves the issue of hazardous goods restrictions and makes sure meats, ice cream, and other items stay fully frozen.

Fully reusable for multiple shipments.  3 times colder than regular gel packs. Provides protection for Cryo vials and other medical samples ensuring they don't thaw out  too quickly when taken out of the cryo-freezer, stored with dry ice or removed from a liquid nitrogen container.

Low freezing point won't allow it to freeze at regular freezer temps so it remains flexible for use in extended cooling gel packs that can stay cold for as long as 6.5 hours!
