During scheduled and emergency repairs on power transformer substations, storage is needed for the storage or even disposal of transformer oil. Our flexible pillow tanks produced from exclusive polymeric materials excel for this purpose.
Heat Resistant
Manufactured using a patented polymeric material, flexible pillow tanks for transformer oils feature great strength and resistance to chemical and climatic effects. Tanks with capacities ranging from 0,025 m³ to 500 m³ can be produced.

The recommended application use of these flexible reservoirs is for the long-term storage of fuels and lubricants, even while hot. Discharged transformer oils at temperatures up to +85 °C. are more easily transferred into our flexible pillow tanks

The use of flexible tanks significantly minimizes costs compared to conventional reservoirs.
Whether temporary or permanent, flexible polymeric pillow tanks significantly reduce road transportation costs compared to metal containers and horizontal tank storage systems.

The weight of a flexible reservoir for the temporary storage of transformer oil is vastly less than that of a steel one. For example, when folded, a Rootank with a capacity of 25 m³ weighs less than 100 kg.

Easy to transport in any vehicle and easily handled by a single person with a trolley for delivery on-site. Special packaging bags can be included for small tanks, designed to be carried by one person.

Customisation Available
Standard fittings include one outlet for draining and filling of oil. However, our production technology allows us to add further valves and fittings in multiple sizes on request if the need arises.

We stock our most popular models - which have capacities of 1 m³ to 50 m³.

To avoid any oil spillage escaping into the environment, and to protect the reservoir from external damaging factors, the package includes an impervious canopy.

Additionally, the package can include the following:
  1. Pumps
  2. Sleeves
  3. Gauge and control sets
  4. Fittings for quick connection
All products come complete with a set of carefully packaged technical documentation.


A 50 m³ capacity tank weighs less than 140 kg when empty.
