Ventilation and product quality

Better conditions for your stacked products during storage and transport

When products are stacked, airflow most often becomes limited — especially deep inside the load. The result is uneven temperatures, trapped gases, moisture build-up, instability, and increased risk of quality loss.

VentiTeq solve these challenges with its simple, durable, and highly effective ventilation spacers which fit seamlessly into your existing logistics workflow.

Why Ventilation Spacers Matter

Efficient Tempering with Ventilation Spacers

✓Consistent Airflow Throughout the Stack

When goods are stacked tightly, the centre of the pallet becomes a dead zone for airflow. VentiTeq spacers create an open 50 mm channel that allows controlled air movement through every layer. This ensures more stable temperatures and prevents localised heat pockets or moisture traps, helping maintain product quality from warehouse to destination.

✓Better Gas Discharge from Sensitive Goods

Many products naturally release gases such as CO₂ or ethylene. Without ventilation, these concentrations rise quickly—shortening shelf life or affecting product characteristics. Our spacers allow continuous gas exchange, helping prevent build-up and reducing the risk of premature ripening, off-odours, or quality degradation.

✓Reduced Moisture Accumulation

Moisture trapped within pallets leads to condensation, mold risk, packaging damage, and weakened materials. VentiTeq spacers promote natural air movement, helping moisture disperse instead of accumulating. This is especially valuable for cardboard-packed goods, perishables, and high-value items sensitive to humidity.

✓Improved Pallet Stability

Uneven packaging, carton collapse, and pressure from stacking can compromise stability during storage and transport. VentiTeq’s patented NVS-III design supports loads edge-to-edge, helping create a more uniform stacking surface. This improves pallet integrity, reduces product damage, and lowers the risk of accidents during handling and transport.

Designed for Real-World Logistics

VentiTeq spacers are built to withstand demanding, high-volume environments. Made from durable recycled HDPE, they are reusable, easy to handle, and compatible with pallet inverters for fast insertion and retrieval—without the need for manual restacking. Whether you manage global shipping routes or short-haul domestic logistics, our spacers streamline operations while protecting your products.

Where Ventilation Spacers Can Impact

✓ Reefer & Controlled-Environment Transport

Refrigerated containers and trucks often experience airflow inconsistencies. VentiTeq improves vertical and horizontal circulation, resulting in more uniform conditions throughout the load—ideal for produce, flowers, beverages, medical supplies, and temperature-sensitive consumer goods.

✓ Warehousing & Long-Term Storage

Products stored for weeks or months risk moisture buildup, temperature fluctuations, and stagnation. Our spacers maintain healthier environmental conditions for stacked goods, helping extend shelf life and reduce losses.

✓ Export & High-Risk Shipments

International transit involves changing climates, handling variations, and long durations. VentiTeq adds an extra layer of protection by stabilising goods and ensuring consistent airflow throughout the journey.

✓ Manufacturing & Packaging Operations

Uneven packaging, carton collapse, and pressure from stacking can compromise stability during storage and transport. VentiTeq’s patented NVS-III design supports loads edge-to-edge, helping create a more uniform stacking surface. This improves pallet integrity, reduces product damage, and lowers the risk of accidents during handling and transport.

VentiTeq spacer models

As with most products, also spacers are found in a variety of designs. Minimal air resistance and support of your box layers are some of the crucial factors.

Our spacers are designed to optimize ventilation between your stacked layers. Have a look at our product selection and find the spacer suitable for your setup.

The unique, 50 mm high and supportive design of the VentiTeq spacers provides minimal air resistance and facilitates as such maximum airflow between your stacked layers

Quality and profitability

Besides maintaining the quality of your products the rigid design and high-quality HDPE material of the spacers ensure a long life span and makes them suitable also for automized handling.

Stable Pallet-Stacks

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

As with most products, there are also big differences in spacer designs.
Minimal air resistance and support of your box layers are two crucial factors.

VentiTeq spacers allow higher air flow and therefore facilitate a noticable more efficient ventilation between your delicate and valuable products.

Controling temperature, humidity and gasses

On the left you see spacers used between stacked bags with mushroom substrate.

Here ventilation plays a key role in managing humidity and temperature levels. By preventing excessive moisture, it helps reduce the risk of mold and other contaminants that thrive in damp environments.

Proper airflow also helps maintaining an even temperature throughout the stack, preventing hot spots. Hot spots can lead to contamination or uneven growth, both of which can compromise the quality of the product.
