Designed for safe Bulk Liquid Transport

Liquid Transport

Our Flexi Tanks are food-grade, multi-layered polyethylene systems designed for safe, cost-effective bulk liquid transport. Manufactured under strict ISO standards, each tank is rigorously tested for integrity and performance.

Services

Installation & Loading Support

Our expert teams provide full assistance during installation and filling, ensuring compliance and ease of operation across the globe.

Custom Accessory Setup

Depending on your cargo type, we recommend and install tailored accessories like bulkheads, thermal liners, heater pads, or PE bins to protect the shipment against temperature changes, oxidation, or physical stress.

Unloading Services

Benefit from our global network for smooth, time-saving unloading services at major ports and delivery points worldwide.

Accessories

Bulkhead: Reinforced steel design with two-bar support for valve safety during transport.

Heater Pad: Positioned beneath the tank, it safely heats contents before unloading—ideal for viscous or temperature-sensitive fluids.

Thermal Liner: Constructed from PP with MET/PET laminates, it insulates the cargo while acting as a protective barrier between tank and container walls.

PE Bin: An advanced polyethylene encasement that eliminates the need for traditional paper lining, adds leak protection, and ensures environmental safety inside 20ft containers.

WHAT’S IT USED FOR?

Products such as wine require heat stability especially during transportation where it is more prone to oxidation due to temperature fluctuations. The liner prevents the conduction of heat, thus keeping your goods in a safe and controlled environment. Although ideal for wine transportation, our cost-effective thermal liners are versatile and cater to a variety of applications.

HOW DOES IT WORK?

Once the goods are fully loaded, the liner is closed thus enabling a temperature controlled atmosphere inside. Made out of high-quality food grade aluminium coated, thermal liners provide complete insulation to your goods by creating a barrier that mitigates the transfer of heat energy through conduction, convection or radiation.
The ISO kits are very easy to set up, with the accessories provided and can be installed within a few minutes. Being economical and versatile, our ISO kits prove to be a worthwhile investment.
