Dry Ice Freezer Packs-Reliable Ultra-Cold Transport

Picture this: A courier sprints through airport security with a life-saving cancer therapy. A researcher collects Arctic ice cores in the Alaskan wilderness. A chef receives Wagyu beef tasting as if it never left Japan. Behind these critical moments stand dry ice freezer packs – portable cryogenic vaults harnessing solid CO₂’s deep-freeze power (-78.5°C) to conquer thermal challenges where traditional cold chains fail.

Why Standard Cooling Fails Ultra-Cold Missions

When biologics demand -70°C stability or perishables face 72-hour transits, conventional solutions crumble:

• Gel packs max out at -20°C – useless for mRNA vaccines

• Loose dry ice sublimes rapidly (5-8%/hour), risking CO₂ buildup

• Active units fail during last-mile deliveries or tarmac delays

• Temperature excursions spoil 20% of high-value pharmaceuticals

Dry ice freezer packs solve this by combining controlled sublimation with engineered thermal inertia, transforming volatile cold into predictable precision.

Tempk’s CryoSure™ System: Where Science Meets Reliability

Tempk redefined freezer pack technology through three breakthroughs:

1. Military-Grade Thermal Control

• Nano-Aerogel Core: Slows sublimation by 40% vs standard packs

• PhaseChange Hybrid Matrix: Absorbs thermal spikes during delays

• -80°C for 96+ Hours: Verified in 45°C Dubai trials (±2°C stability)

2. Safety Engineered In

• Auto-Venting Design: Releases CO₂ at 1.8 PSI (exceeding IATA UN 1845)

• Touch-Safe Surface: Handle at -70°C without gloves

• Antimicrobial Liners: FDA-compliant for direct pharma contact

3. Sustainable Cold Chain

• Carbon-Captured Ice: Uses industrial CO₂ waste (diverts 15 tons/month)

• 35% Less Consumption: Patented geometry extends cooling

• 100+ Reusable Cycles: Outlasts foam shippers 20:1
