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.

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 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.

Refra manufactures liquid ice banks, designed for acumulation of capacity. Such units can be compatible with other refrigeration systems, if the hygienic standards of all units are ensured. The glycol used in the system is usually cooled by a separate chiller. Made with multiple stainless steel thermal coil batteries, built into a large water reservoir, these units work on the principle of ice formation. The glycol mixture circulating in the coil batteries forces the formation of ice on the pipes, thus cooling the water inside the tank. This technology is capable of cooling particularly large amounts of water with relatively little energy consumption.

High capacity liquid-cooled chillers with the cooling power from 140 kW to 2 MW are perfectly suitable for medium to large industrial or large commercial applications. These chillers can be integrated with a dual liquid system, where the condenser uses glycol mixture and the evaporator uses water for the refrigeration process. Due to the glycol-free ability, CS chillers are ideal for particularly sensitive equipment that requires refrigeration with clean, distilled water. CS chillers are assembled on a welded open frame, equipped with maximum 4 screw compressors and shell and tube heat exchangers. Usually stored in special technical rooms and connected to secondary devices such as cooling towers or dry coolers to reject the absorbed heat to an additional fluid loop. Refra manufactures modern devices using plug-and-play ideology, making the installation and use of the devices as easy as possible.
