They are a source of water supply for fire protection systems and networks, such as sprinkler or hydrant systems, and as water drawing points for firefighting units. Our company offers comprehensive construction of above-ground fire tanks: steel tanks made of galvanized sheet metal, stainless steel or covered with elevation trapezoidal sheet metal in any RAL color.
The main advantages of the fire tanks we offer include:
„VdS-CEA guidelines for sprinkler systems. Design and installation”
„Fire protection of buildings. Fire protection water tanks. General requirements”
„Fixed fire extinguishing devices. Sprinkler systems. Design, installation and maintenance”
„Standard for Water Tanks for Private Fire Protection”
The bolted tank technology we offer is a cost-effective solution for storing large volumes of water.
Thanks to our modular design, we offer a wide range of dimensions and capacities. Our standard range includes tanks with:
- capacity from 4 to 2834 m3
- diameters from 3 to 16 m
- heights from 1.25 to 14.45 m
Our series of types allows you to match the tank to: design requirements, site, destination and conditions of use.
If the desired dimensions are not in our standard range, contact us! We will select the optimal parameters for you!
Depending on the static-strength calculations, we use perimeter wind reinforcement system ties.
Access to the roof of the tank is provided by a steel system ladder, along with rests, platforms. On the roof there is a hatch allowing to see inside the tank. The tank is fixed with anchors to the foundation plate, which is also the bottom of the tank.
The tank structure consists of hot-dip galvanized steel elements. The cylindrical shell is made of bolted single steel panels (sheets) of standardized dimensions. The thickness of the metal sheets used depends on the size of the tank and the standard of its manufacture and is selected at the level of strength-static calculations made. Sheets are made of S350GD steel, double-sided galvanized with a zinc coating thickness of Z275, Z350 or Z600. Sheathing panels are properly bored and horizontal and vertical joints are bolted. The selection of the zinc coating is based on calculations of the design life of the tank structure, based on the corrosivity class of the environment in which it is to be seated. In the upper and lower parts, the tank is topped with a perimeter angle bracket.
The roof is made as a self-supporting structure, based on Z type steel beams with a slope towards the center of the tank. The roof covering is available in two variants: uninsulated from T35 trapezoidal sheet metal or insulated from roof sandwich panels with a core of mineral wool or PIR. The roof panels allow for simple and quick installation to the structure with suitable through fasteners. Appropriately designed and profiled tongue-and-groove locks, ensure very good tightness and fast installation. The roof structure provides free drainage of rainwater outside the tank.
All steel components, including bolts, used in the construction of the tank have been protected through a hot-dip galvanizing process. This is one of the best methods of protecting steel from weathering, and such a solution guarantees its long-term protection.
Tank shell panels can be powder coated in any color from the RAL package
The selected membrane tank technology excludes direct contact between the tank walls and the stored medium, which significantly extends the life of the shell.
The membrane installed in the tanks is a product of the highest quality. It maintains the required parameters, which pays off with a very high efficiency during the tank leakage test and a long life of waterproofing.
The EPDM membrane is prepared under production conditions. Prefabrication in advance allows constant control over the parameters of the material and the welding of the elements. Maintaining proper prefabrication parameters affects the quality of the final product. The membrane undergoes detailed quality control before packaging and arrives at the construction site as a ready-to-install component. The pre-prepared membrane significantly reduces the assembly time of the tank, allows installation even during severe frosts, increases the effectiveness of leakage tests eliminating all the problems that can occur during the execution of the membrane at the construction site as is the case with PVC membranes.
We offer two variants of tank shell insulation: internal and external.
For interior insulation, JRtech uses XPS boards, so-called styrodur, usually with a thickness of min. 40 mm. The use of styrodur is supported by its unique properties, which include:
- exceptional hardness and pressure resistance - styrodur is characterized by a low degree of deflection, even with prolonged exposure to a high column of water;
- Overlap connection thanks to profiled edges;
- Very good hygroscopic conditions - low degree of absorption;
- Very good insulation properties;
- fire-retardant - class E according to EN 13501-1:2019-02; and C depending on the requirements of the selected design standard;
- No harmful dust during its mechanical processing;
- high limit application temperature.
XPS is the undisputed leader among polystyrene insulations. It effectively insulates and protects the EPDM membrane from contact with the steel walls of the tank.
The second option is to make external insulation of mineral wool, with the thermal parameters required by the customer and clad on the outside with trapezoidal sheet metal in commercially available RAL colors.
Roof insulation is made of sandwich panels. Sandwich roof panels with a core of mineral wool or PIR. Roof panels allow simple and fast installation to the structure with appropriate through fasteners. The external facings of the panels made of steel sheets with thicknesses from 0.5 mm are covered with metallic and organic coatings.
Insulation of the tank is extremely important for well-powered electric heaters to prevent freezing of the water table. The tank loses the most heat through the water surface (roof). Making a well-insulated tank allows to reduce these losses, which gives the possibility of using heaters with lower power, which affect the cost of operating the tank during the period of low outdoor temperatures.
To meet the expectations of the customer, we give the opportunity to choose the color of the tank.
The choice of facade color allows you to match it with the architecture of the building. As standard, the tank is in the color of galvanized elements. At the request of the customer, the panels of the tank shell, can be powder painted in any color from the RAL package.
In order to completely cover the tank shell, we can also make an exterior facade. It will be made of trapezoidal sheet metal with a vertical profile in commercially available colors.
Serving our experience, we are also willing to take on challenges in the field of aesthetics. Being open to all proposals, we will help to make, for example, corporate advertising, which, with such large areas of tanks, can reduce the cost of expensive advertising banners and additional structures for their installation.
JRtech is actively involved in the process of design arrangements for the inclusion of the tank in the planned fire protection system, both in terms of sanitary, electrical and instrumentation. We offer preparation of a complete construction project, detailed design and workshop documentation. We assist in obtaining a construction permit acting comprehensively.
JRtech's basic scope of supply includes the delivery with unloading of: the tank shell structure; the tank roof structure with its covering; the EPDM sealing membrane; thermal insulation; the tank's heating monitoring system; ladders, the roof inspection hatch; a set of process lines with the necessary fittings.
Installation of the tank is carried out using external hydraulic jacks. It consists in sequential lifting of the tank structure with simultaneous installation of internal insulation and EPMD membrane. Once the tank structure is completed, we proceed to the installation of the remaining equipment, i.e. process piping, water fittings, heaters and electrical switchgear with wiring.
After the installation is completed, the tank is ready to be filled and leakage test conducted. According to the standard, the duration of the leakage test for tanks with non-absorbent walls is 24 hours.
After filling the tank, we calibrate and check the correctness of the water level readings, the correctness of the operation of the heaters and communication with the overriding fire protection system. We take electrical measurements.
After the installation of the tank, we perform training on its operation. We teach the administrators of the facility how to make basic checks, e.g. daily, weekly, monthly. How to respond to operating emergencies and what periodic services to subject the device to.
Upon completion of construction, JRtech will execute and deliver as-built documentation with the necessary approvals and declarations.
Along with the completed construction and conducted acceptance, we provide a warranty card for the product and its operation. The warranty indicates the activities that should be performed to properly protect the tank and maintain an effective warranty.
The tank is founded on a flat foundation slab made according to our guidelines. We can make it for you!
JRtech provides a 5-year warranty on its tanks, which does not include only fittings and electrical components, for which we provide a 12-month warranty.
The warranty runs from the day after the signing of the tank acceptance protocol.
During the warranty period, the user is entitled to free repairs, which are caused by defects resulting from hidden defects in the material and production of the device. Failure to follow the instructions and recommendations contained in the instructions for use and operation of the tank will result in loss of warranty.
Along with the tank comes a warranty card with a list of records for future servicing and repairs that must be made to it to maintain the warranty.
Proper operation of the tank requires periodic annual inspections of the tank, confirmed by a protocol, under pain of voiding the warranty.
