VALROM uses best quality (virgin material) high-density polyethylene (HDPE) for manufacturing aqua PUR® tanks. It ensures a very good ESCR - environmental stress cracking resistance.
Yes. All the raw materials used are approved for the extended contact with water and food liquid environments. The tanks are approved, as products, by the Ministry of health. For a copy of these approvals, enter www.valrom.ro and/or www.aqua-pur.ro.
aquaPUR® is available in 3 volumes: 300, 500 and 750 litres. For details, enter www.aqua-pur.ro.
7. Can the aquaPUR* system be used to store other substances, too? No. the aquaPUR® series tanks were designed to store only water or other chemically inert food liquids.
The thickness of the walls is not relevant for the measurement of the mechanical resistance. Their geometry was designed to provide for minimum distortions at the maximum charge degree. Moreover, the weight of the tank is not relevant for the mechanical resistance or decisive for the quality of the product. The type of raw material, the geometry of the product, the parameters and the technological stages ensure a high-quality product.
aquaPUR® can be used safely, up to a temperature of 40 °C. the liquids with temperatures exceeding this value, even for a short time, can damage the structural integrity and can increase the probability of the distortion or shorten the service life.
The aquaPUR® tanks can be used to temperatures of maximum -40 °C, when they tend to become brittle. If you want to store a liquid into the tank, but you know it will freeze, make sure you have enough expansion space (volume increase due to freezing). In case of damage, the connection elements are easily replaced.
There is no unitary manner of estimating the the service life, due to multiple factors that can influence it, indoor ou outdoor use, etc. from our experience, the service life can be estimated to approximately 20 years. Taking into account the fact that he material is completely recyclable, we recommend that at the end of its service life the system be sent to companies specializing in material recycling.
The warranty period of the tank is 2 years from purchase. If during the warranty period defects occur that are imputable to the manufacturer, VALROM shall replace the equipment with a similar or an equivalent one if the defect cannot be repaired. VALROM’s responsibility is limited to the value of the actual equipment and excludes installation costs and collateral damages.
The manufacturing date (month and year) are stamped into the material used to make the tank. This marking is placed on the front surface of the tank.
No, the tanks cannot be used under pressure.
No, in order to prevent the accumulation of air under pressure into the tank, when high-pressure pumps are used, an air valve shall be placed in the cover.
16. What is a nanofilter? It is a filter with electrokinetic properties – the filtration mechanism being adsorption and/or sedimentation that retains particles under 1 um, for example viruses, bacteria, various colloidal substances and metals (Fe, Al, Cu and Pb) dissolved in water.
No. These methods cannot be used to monitor the filtration system. When the water tastes or smells bad, contaminated substances are already present in the water. In order to ensure an optimum level of filtration, follow the manufacturer’s instructions.
Check the indication of the alarm system.
No. the overflow is a safety element which prevents, in the case of a defected mechanical float, the discharge of the water from the tank. In this case, check the operation of the mechanical float.
What should I do? Stop the system and change the filter, following the steps in the operating instructions.
The minimum water pressure to which the aquaPUR® system can operate at normal parameters is 1.5 bar ± 0.2 and the maximum pressure is 5 bar ± 0.2. IMPORTANT - this is the pressure at which the water enters the system, NOT the pressure at which the tank can operate (see question 14).
22. The pump in the tank starts and stops continuously. Why? The installation is not tight, it has leakages. Check the installation and remedy the defect.
When the highest point of the inner installation exceeds 15 m as compared to the place where the system is installed.
When the red light is on it indicates the absence of the water in the tank. Check the level of the water in the tank, then the tank supply installation. When you have remedied the defect, press the RESET key of the electronic control unit.
The set pressure of the electronic control unit is above the limit of the pump (3.5 bar). Rotate screw 5 of the electronic control unit, clockwise. Press the RESET key of the unit and make sure that the red light is off when the pump stops.
(1) Lack of supply voltage. Check the presence of the voltage at the system supply plug.
(1) There are big losses in the sanitary installation. Check it.
