testing & development

To handle the special requirements for interior design, cooling and recyclability, we work with cooling elements / PCM elements (Phase Change Material), dry ice, cooling and heating elements and insulating materials such as EPS, EPP, Neopor, Piocelan, VIP panels and biomaterials. In addition, we develop our own freezing/cooling fluids (PCM liquids) and Gelpacks also known as gel ice, as far as possible Bio-based. This means that we can accurately customize solutions for several different temperature ranges such as 

Deep frozen -78°C to -30°C
frozen -25°C to -15°C
Cold +2/+8°C  
Ambient +15/+25°C 
And many other temperatures

We are competitive within, among other things, special solutions for online supermarkets and have extensive experience in developing special boxes with an emphasis on the cold chain, transport, process optimization, logistics, washing/cleaning and handling, from warehouse to end customer.

We design 3D CAD solution proposals in our own drawing program and can perform thermal simulations in our software program based on your temperature profile. This gives us a qualified view of whether the 3D CAD design meets the desired needs, and we can perform a thermal calculation to determine the amount of dry ice, cooling/heating elements or PCM in each scenario. We then select the right insulation materials for the thermal box itself. At the same time, we can perform temperature tests in our climate chamber for use in e.g. validation reports.

CFD simulations and temperature testing

Our CFD simulation software is capable of performing approximately 90-95% accurate simulations. In our software, we can simulate over 10 scenarios simultaneously, giving us a quick picture of the most optimal solution. You may want to run several different CFD simulations, testing a range of different insulation materials, coolants, shipping methods/temperature profiles, 3D designs, etc.

Our climate chamber test is similar to running live tests. Here we place one or more temperature loggers inside our solution, where we can measure how it performs when we affect the solution with your temperature profile. Both the simulation software and the climate chamber can quickly perform scenarios that would otherwise take up to a year or more to perform in practice.

We have good experience using the Kelvin Hours technique when calculating the performance of different solutions, or how much a solution needs to perform to fit a customer's transportation plan. Here are two examples of when it can be relevant:

What is the performance of a +2° to +8° solution?
Based on the average external temperature during packing, we will calculate how long it takes for the internal temperature to exceed +8°C.
Here's how we do it:

Average outside temperature minus average inside temperature x number of hours the solution has maintained +2 to +8°C = (22.5°C - 5.7°C) x 48 hours = 806.4 Kelvin Hours.

What is the performance required for a +2° to +8° solution to arrive safely?
    We want to create as realistic a temperature profile as possible. Let's say we know that the transportation time is 45-48 hours divided into several steps such as:Packing and storage at the warehouse before pick-up by the freight company (2 hours at +20°C)Transportation from the warehouse to the terminal (e.g. 3 hours in the middle of the day at +26°C)Storage at the first terminal (14 hours at +18°C) etc.

Then we calculate the average temperature and subtract the desired average temperature inside the box/by the product. We multiply that number by the number of hours the solution needs to hold +2 to +8°C. For example: (22.3°C - 4.8°C) x 48 hours = 840 Kelvin Hour.

The above methods are a great tool for tracking which packaging solution is best suited to transport your product safely with your shipping method.
