Anyone can print a hold-time on a brochure. The question that matters in the Gulf is different: what does the box do when it is sitting in direct sun on a +45 °C day and the surface temperature climbs past +60 °C? We put SafePack in exactly those conditions and recorded what happened.
In a UAE summer field test, an SP32 SafePack was left in direct sunlight. The external temperature peaked at a punishing +63.5 °C, averaging around +37 °C across the test. Inside, the box held the refrigerated +2…+8 °C range for a continuous 49 hours. That is two full days of refrigerated protection in conditions most packaging is never even tested against — and it is a real recorded number, not a marketing ceiling.
A second test targeted the +15…+25 °C controlled-ambient range — the regime for tablets, many finished medicines and diagnostic kits. Under direct sun with the surface peaking above +80 °C and averaging around +43 °C, the SP32 held its range beyond its 96-hour design target. In a milder controlled-ambient test it comfortably reached its full rated performance. The lesson is not a single magic number — it is that the box is engineered for the regime it is asked to hold.
Cold is not only about refrigeration. An SP10 configured with frozen-range thermal elements, conditioned to around −22 °C, was tested in a warehouse holding above +31 °C. It stayed within a −22 to −15 °C band for 53 hours — only a few degrees of drift despite the heat around it. And a compact SP9, built for motorbike last-mile delivery with seven thermal elements, holds a stable temperature for up to 72 hours at +25 °C ambient.
Two things every quality manager should know about these figures. First, these tests used empty boxes. A box packed with chilled product usually performs better, because the payload adds thermal mass — but the exact result depends on the load, so we confirm it per shipment. Second, performance is configuration-specific: model, PCM set, conditioning, starting temperature and ambient profile all change the outcome. That is why our public claim stays at “up to 96 hours under defined conditions,” and why the number that matters is the one tested for your configuration — available with your test report and shipment plan.
Evidence, not adjectives. A recorded curve under a +63 °C sun says more than any brochure superlative.
Figures are from BIOCARD SafePack field tests in the UAE, using empty boxes under the stated conditions; they illustrate configuration performance and are not a guarantee for any specific shipment. Loaded performance is confirmed per configuration.
