CO2 Cascade units are perfectly suited for high temperature climate. This system consists of two refrigeration systems connected via heat exchanger, where one evaporates, the other condenses. Such combination provides either low temperature refrigeration or both: low and medium temperature refrigeration with different refrigerants. Low temperature units can be designed with CO2 and a flooded system to ensure better heat exchange, while medium temperature units obtain a truly cost-effective and environmentally friendly solution when produced with HFC and HC refrigerants. At high ambient temperatures, conventional refrigeration systems require a large amount of energy, whilst propane works perfectly in such conditions. GREEN SOLUTIONS | This unit is a part of Refra‘s environmentally friendly product group, as it is made using natural refrigerants. Such low GWP solutions are designed to have better efficiencies and capacities, as well as less environmental damage.

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.

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.
