10°C and Below Chilled Packout
EPS Insulated Box Packout for 48h Below 10°C Shipments
For chilled products that must stay at or below 10°C, Tempk can supply a passive EPS packout using 14 pieces of 380g 0°C biological ice packs. In the tested 11L payload layout, the shortest measured point stayed below 10°C for 51.2 hours in a 32°C constant-temperature environment.

Target upper temperature limit for this tested chilled packout.
51.2h
Shortest measured duration below 10°C among seven sensor positions.
32°C
Constant ambient environment used for the original Tempk test.
11L

Cas d'utilisation
Use this packout when the product only needs an upper limit below 10°C
This packout is intended for buyers who need a practical starting point for quotation, sample testing or route validation. The key question is whether your product size, route time and temperature rule are close to the tested 11L EPS configuration.
Produits sensibles au gel, variable warehouse dwell time, summer routes above the tested profile, or products that require a different sensor layout or test standard.
Strict 2-8°C pharmaceutical lanes, expéditions congelées, dry ice lanes, ultra-cold requirements, or products that must stay above a lower temperature limit without additional validation.

Test Result
51.2 hours below 10°C under a 32°C ambient test
The shortest measured point was the top center position. For buyer planning, 51.2 hours is the conservative number from the original Tempk test, giving a 3.2-hour margin over a 48-hour requirement.
51.2h
Shortest duration below 10°C, measured at the top center point.
56.5h
Longest measured position in this test, recorded at the bottom corner.
48h +
The tested configuration met the more-than-48-hour requirement.
7 pts
Internal measurement positions used to compare warm spots in the box.
| Sensor Location | Duration Below 10°C | How to Read It |
|---|---|---|
| Bottom of the box | 54.2 heures | Lower-position reading in the EPS cavity. |
| Bottom corner | 56.5 heures | Longest measured position in this set. |
| Front center | 53.5 heures | Mid-facing point near the product space. |
| Middle center | 52.9 heures | Core payload-area measurement point. |
| Right center | 52.4 heures | Side measurement point near coolant placement. |
| Top center | 51.2 heures | Shortest measured position and the practical planning number. |
| Top corner | 51.8 heures | Upper corner measurement point near the lid area. |
Guide de sélection
How buyers can decide whether to start from this packout
This configuration is most useful when the temperature requirement, route time and payload size are close to the tested case. For different risk profiles, Tempk can adjust coolant quantity, box type or validation method.
Start here if the product can accept near-0°C exposure and only needs to remain below 10°C during the route.
Because the coolant phase-change point is 0°C, products with lower-limit concerns should be tested with the real payload and packing method.
Consider larger box volume, plus de liquide de refroidissement, different insulation, lane-specific preconditioning or a new temperature profile test.
Those requirements need a dedicated packout and acceptance rule instead of borrowing this below-10°C test result.
Test Context
What the test photo helps confirm
The photo gives buyers a practical view of how the packout was prepared. Pour les achats, the important question is whether your product, payload mass and handling route match the original test closely enough.
What Tempk should check before sample confirmation
Confirm product dimensions, payload weight and whether the product can fit inside the 250 x 140 x 320 mm effective space.
Confirm whether the product only needs an upper limit below 10°C or also has a lower temperature limit.
Compare route duration, exposition ambiante, warehouse dwell time and handoff points with the 32°C test condition.
Prepare a route-specific or customer-specific validation if the order requires a temperature report before bulk purchase.

Buyer Questions
Common questions for below-10°C EPS insulated box projects
How long did this packout stay below 10°C?
The shortest measured position stayed below 10°C for 51.2 hours in a 32°C constant-temperature environment.
What configuration was tested?
The tested setup used a 21L EPS insulated box, 11L effective payload space and 14 pieces of 380g 0°C biological ice packs.
Does this automatically qualify my route?
Non. It is a tested result from one configuration. Your route should be checked against payload size, sensibilité au produit, transit time and ambient exposure.
Can this be used for 2-8°C pharmaceuticals?
Use a dedicated 2-8°C pharmaceutical packout instead. This solution supports a below-10°C upper-limit requirement, not a narrow regulated range.
Why is usable payload space only 11L?
The EPS box is listed as 21L, but the tested payload space is about 11L because the 14 ice packs occupy space around the payload.
Can Tempk adjust this for longer routes?
Oui. Tempk can compare insulation material, taille de boîte, ice pack quantity and sensor layout, then prepare a modified sample test.
Need a below-10°C insulated box packout for a 48h route?
Share your payload size, exigence de température, route duration and purchase plan. Tempk can check whether this 11L EPS packout is suitable or prepare an adjusted sample packout before bulk procurement.
