Framless portable water tanks Hydronion®

testuje se additional info

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.

Complete Tank Equipment:

  • Boston-type valve in the tank’s inflatable rim
  • DN100 4″ flanged connection with Storz 110 coupling and cover
  • Protective mat under the tank (650 g/m²)
  • Cover for easy storage and transport

Components of the Hydronion® tank

Filling and discharge

Storz couplings allow for rapid hose connection in emergency situations.

Quick assembly

Lower side handles facilitate tank deployment.


Reflective elements

They enable quick location of the tank and valve in areas with limited visibility.

Protective mat

Protects the tank bottom from damage caused by sharp objects.

Hydrophobic foam collar

It does not absorb water and prevents water from spilling under the pressure of the fire hose.

Carrying cover

Protects the tank during transport and facilitates safe storage.

Why choose the Hydronion® tank?

The Hydronion tank is an effective alternative to traditional frame tanks. After many discussions with firefighters, we know that time and mobility matter — our tank sets up in just 2 minutes, takes up very little space when packed, and requires no frame assembly. It’s a solution that genuinely improves field operations.

Hydronion® tank

  • High tank durability thanks to the use of 1000 g/m² fabric
  • Quick assembly taking just a few minutes – simply spread it out on a flat surface and fill with water
  • Protective cover for safe storage of the tank
  • Compact size when folded, making transport and storage easier
  • 5-year warranty

Standard frame open tank

  • Increased risk of material damage due to low fabric weight (650 g/m²)
  • Long assembly time — approximately 30 minutes
  • Limited number of handles to assist with assembly and disassembly
  • Bulky and inconvenient storage when folded, taking up relatively large space
  • The tank frame consists of many parts that are easy to lose
  • 1 to 2 years warranty

Portable water tanks Hydronion®

Hydronion® self-supporting, portable firefighting tanks are a key component of modern fire safety systems. These innovative solutions provide immediate access to water in emergency situations, which is invaluable during firefighting operations in areas far from standard water infrastructure. Crisis management services, for whom mobility and rapid response are top priorities, particularly appreciate their value.

Thanks to their quick deployment capability and large capacity, these tanks enable effective protection of communities in fire hazard situations. Their versatility makes them suitable for firefighting in remote forested areas as well as in industrial and residential zones.

It is worth emphasizing that portable firefighting tanks not only enhance the efficiency of emergency response efforts but also play a crucial role in a proactive fire protection strategy, allowing for better preparedness against potential threats.
