Description
The UniHeat 72 hour heat pack (shipping warmers) is a popular heat source for those who are shipping reptiles, amphibians, insects, invertebrates, fish, plants and other perishable items.
The 72 hour heat pack will activate in under an hour and reach its peak temperature of 115°F (46°C) in approximately 4 hours. The heat pack will then gradually drop to 100°F (38°C) for remainder of its operational life. One 72 hour heat pack will increase the temperature of a 1 cubic foot insulated box by approximately 15 degrees, for every additional heat pack that you use the temperature will raise an additional 10 degrees. Ideally the 72 hour heat pack is used for priority 2-3 day shipping (with out delays), as they are not recommended for 3+ days shipping. Please order our 96 hour heat packs for shipments that require 3 or more days of transit times.
Heat packs are not guaranteed to keep animals or plants alive in extreme winter temperatures, as there are many variable to consider. We don’t recommend shipping when the overnight temperature along the shipping route stays below -30°C (-22°F) Make sure you use an appropriate thickness of sheet insulation to line your shipping box. We will use 3/4″ to 1.5 inch (2-4 cm) thick insulation to line our boxes. This will depend on what we are shipping and the over night temperatures. Heat packs get very warm once they reach their peak temperature, as such, please take precautions not to allow the heat pack to be in direct contact with the animals or plants you are shipping. Winter in Canada can be unpredictable, and carriers experience delays quite often, as such, always allow at least one more day of shipping than the carrier claims to offer. We recommend to avoid shipping perishable items during the extreme rush of Black Friday and Boxing Day sales. Please use good judgement when packing live animals and plants for shipping, their well being depend on it.
