The AMARGO company under the development of the business offers a wide range of tanks for the "outside" - underground and aboveground, and for use indoors with capacities ranging from 900 liters to 6,000 liters (standard, larger volumes on the order), made of high density polyethylene plastic PE HD with the rotational molding- rotomoulding.
To clarify, Rotomoulding (otherwise: rotational molding) is a plastic molding technique, a form of rotomoulding is divided into two or more parts, is powdered with micro-powder or granular of plastic material and then placed in an oven (temperature of about 200°C) - is also rotated against both axes so that the material, which at that time becomes liquid will form itself on the walls. Then the form is cooled and opened, and the finished article is extracted.
  The basic advantages of rotational molding:

production does not lead to the formation of internal stress,
elements - tanks, shafts, wells, small wells, domes made in one production cycle, in one element, without any connections - welds,
high wall thickness,
stability of the massive use of forms,
the confirmed best shape of profiles that ensure the stability of the structure of the tank plus an additional GreenLife reinforcing ribs, resulting in a maximum static strength of the tank against tank, for example, made in the shape of a cylinder - the drum, which are only conditionally for installation underground.

 
The offered tanks are made entirely of the form of a certain shape, most with already finished manhole and manhole cover as a compact. The produced tanks are ideal for, inter alia, storing water, both for drinking and fire protection and rainwater in the systems of recovery, retention and reuse.
In the case of the use of the storage tank and pumping drinking water, for production we use - the primary granules in white-approved hygienically - proven physiological indifference to direct contact with drinking water (as in the case of plates offered: PE, PP- Polish Institution of Hygiene certificate).
Color of tanks for drinking water from the physiologically inert PE plastic is presented by the following picture (the picture presents a standard tank with a higher capacity).
 
THE ADVANTAGES:

series with sliding dome for horizontal or vertical adjustments to the needs,
independent manhole of 600 mm consistent with DIN 1989
continuously monitored quality complying with conditions of allowance of the type of structure,
high stability of form,
supply without the need for specialized crane unloading (reduction of installation costs),
ready to connect the supply, transfer and connection to the house,
does not transmit light,
resistance to ultraviolet radiation in order to ensure consistent quality of material and long service life,
the possibility of recycling container - plastic PE HD - undergoes a 100% recycle.

 
  Consistent quality management, new technology and the best selection of materials allows the above ground, underground tanks and windows - underground wells offered by our company to meet the highest requirements. Therefore, once all the conditions of the assembly instructions are fulfilled, we offer a 15-year warranty for our underground tanks.
  In the technology of rotomoulding, we offer tanks with capacities ranging from 1000 to 6000 liters.

For larger capacity we offer tank banks or design as round tanks PE HD / PP DN 1000 and 1200 mm produced on the basis of the round rings or rectangular containers made individually on the basis of structural coffers so called "wall elements" (integrated injection technology - a "honeycomb" of PP built on the one side as a plain flat plate, on the other side as a grill of vertical and horizontal at a height of 100 mm in the lateral elements - the reinforcement of 80 mm and 10 mm thick) with a welded connection using adhesives - welding wire from the native material.
We are also able to produce tanks from the coffers or plates on-site- for example in the basement / storage rooms. Sample implementation of the buffer tank for water supply for the installation of pump to supply fire hydrants in residential high-rise buildings - "blocks – skyscrapers" was presented in the section of Construction coffers PP for the construction of tanks.
