PCM Packs

When transporting temperature-sensitive consignments over medium to long distances, Phase Change Material (PCM) packs are unquestionably the most comprehensive and versatile cold chain solution on the market. The way they function makes them the ideal component for keeping temperatures regulated inside your shipment. Tempack PCM packs provide fusion temperatures that range from -4ºC up to +37°С — and they need no pre-conditioning. It’s this degree of adaptability that allows these phase change cold packs to be configured for the transport of blood, vaccines, pharmaceutical and biological products, reagents, samples and many other thermolabile products that need guaranteed temperature stability throughout their journey. Like the Tempack rigid cold and frozen packs, the PCM pack is engineered from high-density polyethylene. This extremely robust and resilient casing is then transformed into a “smart” cold pack, as various phase change materials with different melting points are added.

With such scope where fusion temperatures are concerned, PCM packs can be configured to emit or absorb heat at +3°С or +5° С, allowing products to remain stable in the +2° to +8°С refrigerated range whether being shipped against summer or winter profiles. Likewise with the +15° to +25°С ambient bracket where the PCM melting point is around +22°С, or +37°С. Each PCM heat-accumulation substance behaves according to a solid-to-liquid and liquid-to-solid phase change processes. At melting point, the PCM absorbs and stores great quantities of thermal energy, releasing it again when it’s frozen. As temperatures oscillate, these fluids recharge. By minimising any possible effects of sudden temperature changes, Tempack PCM eutectic cold packs have been a real boon for longer distance transportation, as the integrity of shipments are protected even across hemispheres when outside temperatures fluctuate greatly. Not only is this another safer alternative to deploying the one-way, dry ice solution, it is also a reusable option.
