Insulated thermal covers are used as a passive cooling system to protect the temperature of temperature sensitive goods against unwanted external or outer temperatures. Therefore the thermal cover is pulled over a pallet or roller container on which the temperature sensitive goods are loaded.

The insulated thermal foldable cover or BI-FOLD is a multiple use cover for roller containers which is produced with foldable systems so the covers folds open or closes automatically. The purpose of this folding system is to create a faster and repeating usage of the cover. Due to the folding system in the cover, the handling is been reduced from minutes in only seconds compared with traditional covers. 

This explains the reason why this special foldable cover is in use at some of the biggest supermarkets in Europe. To create the folding system, plates are implemented in the roof and sides in the cover. In the back of the cover a light weight aluminum construction is implemented so the cover can be handled as a flat plate for the return flow. All these implemented systems make the cover more than just an insulated cover. It make the cover a logistic asset for the fast and efficient logistics of temperature sensitive goods and products.

Most roller containers have bottoms which are not completely closed so air can flow through these openings. Therefore it is very important to seal or insulate the bottom of the container before loading the chilled or frozen products. An insulated bottom will increase the temperature results significant. To insulate the bottom a on-way use insulation or cartboard can be used. See Insulation

When a roller container is filled, it can happen that the roller container is not completely filled. Yet the roller containers have sidebars which stand higher than the filled goods. This means that air can remain in the roller container between the goods and the top of the insulated cover. The amount of air will influence the temperature preservation and temperature result. The more air in the roller container, the lesser the temperature result will be. Notice that volume and mass of the loaded goods is the basic item for long or successful temperature preservation. Next to the volume of air in the roller container also the temperature of the air in the roller container determines the temperature preservation or temperature result. If the temperature of the goods is +2°C and the air within the roller container and thermo cover is +18°C, then this +18°C will have an impact on the temperature of the goods. Therefore it is important that the conditioned goods are loaded in the same conditioned chamber and that the insulated cover is pulled over the roller container in the conditioned chamber so no warm air is packed together with cooled goods.

The insulated covers are made out of strong yet light weight materials so they can provide a long duration of life. Supermarkets and transport companies who are using the thermo covers experience a lifetime between 3 and 5 years.

The used foils in the insulated covers are water resistant so they can be easily cleaned which is important for the hygiene when the insulated cover is used for food or pharmaceutical goods.

If the insulated cover is used for one way or re-usable purposes the insulated cover can be provided with several tracking and tracing systems as unique numbers, barcode or RFID technologies. Krautz develops tailor made software solutions for tracking and tracing systems. See page : Track & trace
