The self-supporting, open design of the Hydronion® flexible tank requires neither permanent ground anchoring nor any additional supporting structures. Its open form offers several advantages, including faster filling and emptying of the water reservoir. The tank’s optimal height when fully filled allows it to be used for refilling helicopter-mounted firefighting water buckets.
The Hydronion® tank is equipped with two flange connections fitted with Storz 110 GW couplings, enabling simultaneous filling and water extraction by multiple units. This eco-friendly tank holds a CNBOP approval certificate, confirming compliance with fire safety requirements.
The water tanks are available in capacities of 5,000, 8,000, 10,000, 15,000, and 25,000 liters. Custom-designed Hydronion® water tanks can also be manufactured according to specific requirements.
