What are savENRG® CRT Packs? 

savENRG® Controlled Room Temperature (CRT) Packs are manufactured using a paraffin-based phase change material (PCM). This material solidifies as the surrounding temperature drops from 20°C to 15°C (68°F to 59°F) releasing heat and then melts as the temperature rises from 15°C to 20°C (59°F to 68°F) absorbing heat.

Why are savENRG® CRT Packs better than regular gel packs?

savENRG® CRT Packs work best in the range of 15°C to 20°C (59°F to 68°F) while gel packs work best in the range of -5°C to +5°C (23°F to 41°F).

When a gel pack is used to keep a product from overcooling within a room temperature range of 25°C to 15°C (77°F to 59°F), its capacity to absorb cold from the ambient temperature is low – 4.186 J/gC (1g of gel cools down by 1°C while it absorbs 4.186 Joules of cold).

When a savENRG® CRT Pack is used for the same application within a temperature range of 20°C to 15°C (68°F to 59°F), its capacity to absorb cold from the ambient conditions is very high – 230.000 J/gC (1g of savENRG® CRT PCM absorbs 230 Joules of cold without changing temperature). Thus, a smaller quantity of savENRG® CRT PCM can safely keep a product from overcooling as compared to the quantity that will be needed for a gel pack.

When to use savENRG® CRT Packs:

Specialty pharmaceutical products that need to be maintained at controlled room temperature conditions of 15°C to 25°C (59°F to 77°F) are often shipped overnight from the distributor directly to the patient. These products have a high likelihood of exposure to extreme cold temperatures during winter. A regular gel pack cannot protect the product from overcooling while a savENRG® CRT Pack will efficiently keep the product above 15°C (59°F).

Features of savENRG® CRT Packs:

• Environmentally safe oil-based organic PCM
• An energy saving, sustainable alternative to gel packs for controlled room temperature applications
• Tested for consistent stability over multiple uses for thousands of cycles
