Flexitanks single use or reusable
The first flexitanks marketed were reusable and needed to be cleaned before further use,making them inconvenient. We currently only use single-use flexitanks. Thus, the exporter has the full assurance that there will be nocontamination by a residue from a previous product.
Number of layers of a flexitank
Considering the number of layers which it is manufactured, there are three types of flexitank:
- Multilayer flexitanks: the first flexitanks were made between 4 and 5 layers of polyethylene. The main advantage of the multilayer flexitanks is that each layer is very thin and flexible, making it very easy when the download is complete roll the semi-empty flexitank to not leave losses (like a toothpaste tube it were). However, these layers as thintend to break easily, allowing part of the product is left between the layers and their recovery is impossible.
- Monolayer Flexitanks: this type of equipment is manufactured in a single layer of polyethylene thicker than multilayer flexitank, and thus less flexible. Its main advantage is that no product can remain between the layers. However, because it is less flexible it is more likely to occur a stress crack or rupture inthe pocket caused by excessive force, generally in a corner, which can not be absorbed.
- Bilayer flexitanks: combining the advantages of the previous two systems, was born onflexitank bilayer. It is manufactured with a layer of polyethylene, hard as monolayer but thin and flexible, laminated with a second twisted layer which protects the interior of the irregularities of the container.
Flexitanks upper or lower load
There are two systems of loading / unloading in the flexitanks market:
- Upload/download above: flexitank is equipped with a valve on top of it, which means that both loading and downloading an operator must climb above the bulkhead, to connect and disconnect the hose. While the charge and discharge is simpler, it is a system less secure, less easy and costly in time.
- Upload/download below: in this case the valve is located on the bottom front of theflexitank and passes through the bulkhead or bulkhead, which is simple and safe to connect the hose to load or unload.
Flexitank with thermal insulation
Depending on product type, weather conditions and temperature range desired, we can install the flexitank with thermal insulation, ensuring the desired temperature from product load until his discharge on arrival.
We have a serpentine carpet that, placed when the flexitank is installed, allow the product to be heated until it is liquefied, thus enabling its discharge.
