Optimal airflow

In the world of fresh produce, every step in the supply chain makes a difference. From the moment your products are harvested until they arrive at their final destination, even small temperature variations can affect freshness, appearance and shelf life. That is why smart transport solutions are essential to protect quality, reduce waste and meet the expectations of your clients. 

At HDG, we understand these challenges and have developed a powerful tool to improve cold chain performance. Our innovative solution, Otflow, is designed to optimize airflow inside reefer containers. By guiding cold air evenly throughout the cargo space, Otflow helps eliminate hot and cold zones that often lead to product damage or decay during long distance shipments.

Whether you are shipping bananas, citrus or berries, Otflow gives you more control over transport conditions. It reduces losses, lowers the number of claims and helps extend shelf life, all while being easy to use and fully recyclable. With Otflow, you upgrade your container into a smarter and safer environment for your produce.

Proven impact around the world.

Otflow is trusted by growers, exporters and importers across six continents. Whether shipping bananas from Ecuador, citrus from South Africa, or avocados from Mexico, Otflow has proven to reduce temperature fluctuations by up to 30 percent during transit. This not only improves product condition but also enhances your position as a reliable trading partner.

The cooling should circulate throughout the entire container. Unfortunately, without OTFLOW®, the internal airflow is not that effective, resulting in 'Hot Spots' that lower the quality of your cargo, often paired with great (financial) losses.

With OTFLOW the cold air reaches all corners of the container, keeping the temperature equal from front to back (tested and proven by Wageningen Biobased Research Facility). Better flow means less food waste, less financial losses and higher product quality.

“The OTFLOW® floor cover reduces the temperature difference between warmest and coldest location in shipments of precooled grapes by approx. 30%.”

— Dr. ir. (Leo) Lukassen  |  Researcher Wageningen Food & Biobased Research.

OTFLOW is developed and tested with Wageningen University.

In 2016, Dr. ir. Leo Lukasse from the Wageningen Biobased Research Facility initiated a research to find out how to reduce the temperature differences inside cooled containers by covering the floor.

Temperature maps from Wageningen’s research conclusion show that containers with OTFLOW benefit from improved temperature difference; eliminating harmful hot/cold spots.

When the temperatures reached it's highest point during the shipment, the temperature map shows that containers with OTFLOW® benefits from an improvement of 30%; eliminating hot/cold spots and keeping fruit fresh.

Big size, big impact.

"The entire process of placing OTFLOW into the container is very practical and easy to do."

"Since the air flows are better regulated, the chance is considerably greater that the entire load is of perfect quality. We now intend to use OTFLOW® on other overseas lines, such as for our mangos. Certainly for The Greenery, where sustainability and quality are of paramount importance, it is important that the ventilation in the containers is increasingly optimized.”
