Common questions
How long do Re-Freez-R-Brix® Cold Bricks maintain temperature?
Re-Freez-R-Brix® Cold Bricks provide consistent cooling for over 12 days, making them ideal for long-distance pharmaceutical and biotech shipments. Actual duration depends on ambient conditions, insulation layer thickness, and product load.
Are these cold bricks compliant with pharmaceutical shipping regulations?
Yes. Formulated with food-safe, non-toxic materials, these bricks meet FDA and international pharmaceutical shipping standards. They require no special hazmat declarations, unlike dry ice, simplifying logistics and reducing costs.
What's the advantage over gel packs or ice?
Unlike traditional gel packs that leak or ice that melts, foam refrigerant bricks maintain uniform temperature without thawing, prevent cross-contamination, and refreeze reliably for multi-use cycles. This durability translates to lower per-shipment costs.
Can I use these bricks in insulated shippers of different sizes?
Yes. The 4 1/2" x 4" x 1 1/2" dimensions fit standard insulated containers and coolers. Multiple bricks can be arranged to maximize cooling coverage. Consult Packrift's sizing guide to optimize configuration for your specific shipment requirements.
