Efficient blast freezing with freezer spacers

Freezer spacers are an essential part of optimising your blast freezing process. A lot of energy can be saved by freezing smarter. By knowing about the entire freezing process, you’ll know where and how to optimize.

Optimal airflow in blast freezing

The way to efficiently blast freezing is to understand how the air flows inside your freezing chamber.

Here it all comes down to optimal airflow – between your pallets and box layers as in the freezing chamber.
As air will always choose the path with the least resistance, it prefers to go around your pallets.

As this only indirectly will cool/freeze the middle layers of your pallet stacks, the freezing will be unnecessarily long and expensive.

How do spacers enhance the blast-freezing process?

By inserting spacers between your box layers, you allow the air also to extract heat from the centre of your pallet stacks. And at the same time facilitating a better airflow in the entire freezing chamber.

Amongst others, VDKL (Verband Deutscher Kühlhäuser und Kühllogistikunternehmen – The German union of cold storage and logistics) highly recommends using spacers in blast-freezing processes.

Crucial factors to improve the blast freezing process

As you can imagine there are big differences between spacer designs. Minimal air resistance and support of your box layers are some of the crucial factors.

Let’s dive into the main factors that help you improve your blast-freezing process:

  • 1 e1678187837185

    The unique, 50 mm high and supportive design of the FreezeTeq spacers provides minimal air resistance and facilitates as such maximum airflow in your freezing chamber.

  • 2 e1678187916842

    Not only reduces the time required to freeze your products, but also enables a lowering of the fan speed. This results in potential energy reductions of as much as 75% - and with that considerable cost savings.

  • 3 e1678187941649

    The large and evenly distributed support area of the spacers also ensures that your boxes do not collapse and thus are damaged and block the airflow.

  • 4 e1678187953990

    Last but not least the rigid design and high-quality HDPE material ensure a long life span and makes them suitable also for atomized handling.
