Reefers are not made for pallets

The t-bar floor of a reefer is designed to ship boxes, not pallets with boxes. The difference is that carton boxes cover the air channels of the reefers floor while pallets are open underneath and the cold air will no longer follow the channels.

Creating a new flow

The unique shape of the OTFLOW is calculated and tested by the University of Wageningen to produce the optimal distribution of air inside the reefer with palletised cargo. This provides the much needed solution for cooled and palletised transports.

Amazing results

OTFLOW effect on internal reefer temperatures has been thoroughly tested by Dr. ir. Leo Lukasse from the Wageningen Biobased Research Facility. His research concluded that OTFLOW reduced the temperature difference by more than 30%. 

Airflow with OTFLOW®

With OTFLOW installed underneath the pallets the cold air reaches all corners, eliminating all hot spots that can harm the precious cargo during transport.

Airflow normal reefer

The cold air from the cooling unit is not being distributed to all corners of the container. This creates hot spots that increase the respiration rate of the fruit.
