Cold Chain Assurance for the 2-8°C Segment
At Airfield Express, we understand that transporting temperature-sensitive pharmaceuticals, vaccines, biologics, and diagnostics requires absolute precision. For products that must remain strictly within the 2–8°C range, passive cooling systems are a critical component of our cold chain assurance.
Unlike active refrigeration, passive cooling relies on highly engineered, pre-conditioned coolant packs to absorb heat during transit. The objective is to maintain the payload within the exact required temperature range from origin to destination, without relying on an external power source.
Our Approach to Passive Cooling Solutions
Depending on the payload, transit duration, and specific handling requirements, we utilize optimal cooling technologies to protect your shipments:
Gel Ice Packs
A reliable, cost-effective solution for standard pharmaceutical distribution. Pre-conditioned to maintain the 2–8°C environment over shorter domestic transit lanes.
Phase Change Materials (PCMs)
Engineered for higher thermal stability, PCMs absorb and release thermal energy at specific phase transitions, offering extended temperature hold times for long-haul routes.
Hydrated Phenolic Foam Bricks
The premium standard for professional 2–8°C cold-chain applications. These bricks offer high thermal mass and uniform cooling, significantly reducing the risk of your payload coming into contact with excessively cold surfaces.
Why the Complete System Matters
The success of a 2–8°C shipment is never determined by the coolant alone; it relies on the complete thermal packaging system. Throwing the coldest possible pack into a box is a risk—excessively cold coolants can cause payload temperatures to drop below 2°C, compromising critical pharmaceutical products.
To ensure complete thermal stability, Airfield Express evaluates the entire transport ecosystem, including:
Validated Temperature Control
For life-science shipments, the ideal passive cooling solution isn’t the one with the highest raw cooling capacity. It is the one that delivers a stable, uniform, and validated temperature profile. By balancing advanced packaging technology with meticulous operational protocols, we ensure your critical payloads are protected from freezing and heat exposure alike.
