Retention and storage tanks


NavoTech storage tanks, depending on the needs and conditions of use, are manufactured in various material and construction versions:
single or multi-chamber, as flow-through and drainless devices, with side inlet or outlet, and with additional inlets.

The tanks are intended for underground development in green areas or communication routes.

The size and volume of the tanks is only limited by road transport. The tanks can be combined into complex modules and then the working volume of the system is unlimited.

If necessary, we can help in choosing and arranging the appropiate retention system, which will include other components of the system such as: linear drainage, flow regulators, separators, pumping stations, backflow preventers.

Tanks offered by NavoTech include:

ROK-PE double-walled, structural, made from polyethylene,

ROK-R spiral, stell,

RET made of polyethylene, tank working volumes up to 3.2 [m3].



ROK-PE polyethylene tanks


Purpose

- retention tanks, rainwater buffer and storage facilities, sewage, aggressive media,
- tanks used in open technical and industrial installations: water treatment plants, water and sewage treatment,
- fire-fighting storage tanks,
- storage tanks for drinking water used for household purposes (with PZH approval for drinking water),
- elements of plumbing installations et. case of the pumping station, sewage treatment plants, separators, measuring and water meter wells.

 

Construction

ROK -PE polyethylene tanks, in the shape of a cylinder and horizontal, are made of high-density polyethylene PE-HD based on structural spiral double-walled pipes with high circumferential stiffness SN2 ÷ SN8. The proposed tanks are easy to install (the smallest devices do not require the use of lifting devices) and non-harmful to the natural environment. The tanks do not require the use of additional protective coatings and other maintenance procedures.



ROK-R steel tanks


NavoTech has permanently introduced steel tanks made of a spiral-corrugated pipe, protected on both sides by pressure and thermally pressed Trenchcoat coating.

Purpose

The ROK-R steel tank can be successfully used as an external tank, non-pressurized sewage system for assembly: in the ground, in the road lane under the road,
in other sites used for communications engineering:
- fire-fighting water tanks,
- retention reservoirs, rainwater buffer and storage facilities,
- elements of plumbing installations et. case of the pumping station, sewage treatment plants, separators, measuring and water meter wells.

 

Construction

ROK-R steel tanks are made on the basis of a spiral corrugated pipe, protected on both sides by pressure and thermally pressed Trenchcoat coating. Under the Trench-coat layer, anti-corrosion protection was applied in the form of a zinc coating with a thickness of 40 μm applied by fire method. The wall of the tank has a multi-layer PE-Zn-St-Zn-PE cross-section.



RET polyethylene tanks


Purpose

RET tanks by NavoTech are designed for storing water and sewage for domestic and industrial purposes with small volumes. They can be used as elements of systems: sewage treatment plant, irrigation, water treatment. RET tanks can also be used to collect rainwater in households.

 

Construction

Made of high-density linear polyethylene, stabilized against UV rays. In the process of rotational molding, monolithic products are created, i.e., without joints of high strength and impact resistance. At the edges and transitions, the walls are thickened by about 50%. The use of selected, non-toxic raw materials for the production of tanks guarantees the production of products free from defects and suitable for contact with food. The proposed tanks are light due to the low specific weight of polyethylene and easy to keep clean due to the very smooth external and internal surfaces.
