Freezer spacers
Optimal air circulation for efficient cold storage
Efficient freezing of products is crucial in sectors such as the food industry and the pharmaceutical branch. A well-designed freezing process revolves not only around reaching low temperatures but also around speed, energy consumption, and product quality.
Freezer spacers (also known as freezer mats) are indispensable in this regard. By placing these open plastic mats between stacked layers, you break the insulating effect of the stack. This allows cold air to circulate freely between the products, which is essential for processes such as blast freezing and tempering.

Yet, they are not yet utilized to their full potential everywhere. Some companies still work with outdated stacking methods that not only slow down the process but also consume unnecessarily high amounts of energy. In a market where cost control and sustainability set the agenda, it is time to value the freezer spacer as an essential logistics instrument.
The physics of a perfect freezing process
The greatest challenge in freezing is ensuring a homogeneous temperature distribution throughout the entire load. Without spacers, stacked boxes act as an insulating blockade, preventing core heat from escaping. The use of Q-Pall freezer spacers breaks this insulation:
- Optimized airflow: The open structure forces cold air between the layers, maximizing heat transfer (convection).
- Preservation of cell structure: Faster freezing prevents the formation of coarse ice crystals in the product. This is crucial for maintaining texture, taste, and nutritional value, particularly in the meat and fish industries.
- Predictability: You eliminate 'hotspots' in the pallet, ensuring that every package reaches the same core temperature.
Hygiene: Why plastic is the only option
In the food and pharmaceutical industries, hygiene is non-negotiable. Traditional spacers made of wood or cardboard are a risk factor here; they absorb moisture and form an ideal breeding ground for mold and bacteria.
Our plastic spacers (manufactured from HDPE) completely eliminate this risk. They are:
- Easy to clean: Resistant to high-pressure cleaning and chemical agents.
- Moisture-resistant: Do not absorb liquids or odors.
- Durable: They do not splinter and last for years in a rotation system, contributing to circular operations.
ROI: An investment that pays for itself
Although the initial purchase of plastic freezer spacers is higher than disposable materials, the Total Cost of Ownership is significantly lower. By shortening the freezing time (sometimes by up to 40%), you save directly on the energy bill of your cooling installations. Fewer operating hours also mean less wear and tear on compressors and evaporators.
Whether you are active in the food sector, pharma, or logistics services: the question is not if you should integrate freezer spacers, but when you will stop wasting energy.
