Tanks - Import export

Astra will help you choose the right storage tank design and size for storing your product at the desired temperature, staying homogeneous, without changing original product structure. 10 liters is the smallets tank was produced at "Astra" and a largest was distillation column of 500,000 liters. We are not afraid of oversized products, only two questions remain, is there a way to deliver it to your site and will the produced tank fit into your factory?

Refra manufactures hot water tanks, tailored to various heating systems. With an operating pressure of 6 to 10 bar and the capacity of 300-3000 liters, these water storage and preparation tanks can help maintain the required amount of liquid for service continually and ensure a constant supply of hot water for comfortable consumption. Refra hot water tanks are available with an anti-legionella kit, which consists of a recirculation pump, heating element and timer. This kit prevents the spread of bacteria and is therefore particularly important for domestic water systems. A special 6 or 9 kW electric element can be added for additional water heating that will heat the water in the tank to the required temperature. The tank is made of carbon S235JR or 304/316L stainless steel, externally insulated with an additional (50-100mm) layer of polyurethane and lined with a high-quality red dermatine fabric. Both vertical and horizontal tank

Refra cold water tanks with an operating pressure of 6 to 10 bar are used to increase the amount of liquid in the refrigeration systems and can be produced as system component or a completely separate product. The water tank with possible 300-3000 liters capacity will help to keep a constant cooling cycle, thus stabilizing unit operation and avoiding poor water temperature control. Cold water tanks can also be used for water flow separation. A built-in separation plate or a blast pipe ensures smooth operation of the unit and maintains consistent water temperature in the system. This feature gives the opportunity to regulate the volume of liquid, used for different circuits. The tank is made of carbon S235JR or 304/316L stainless steel, externally insulated with an additional layer of ArmaFlex and lined with a high-quality blue dermatine fabric. Both vertical and horizontal tank positioning is possible together with threaded, flanged or victaulic joints.

Refra buffer tanks with an integrated heat recovery are an innovative and highly cost-effective systems that are rapidly gaining popularity in commercial sector. A special buffer tank with a built-in double wall heat exchangers acts as an intermediary to collect and utilize excess heat. This system is characterized by the fact that it allows the heat generated by the operation of the refrigeration equipment to be used for other heating purposes in the same building. By installing one system, the customer gets heating and cooling at once, as well as huge savings in energy and equipment costs. These tanks are available with an anti-legionella kit, which prevents the spread of bacteria and is therefore particularly important for domestic water systems. A special 6 or 9 kW electric element can be added for additional water heating that will heat the water in the tank to the required temperature.
