Co2 - Import export

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.

CO2 Container is a new generation solution that covers most refrigeration needs. It combines both transcritical and subcritical CO2 systems with a unique AR frame, designed exclusively by Refra. Cooling capacity of this product ranges from 50 kW to 600 kW, meaning that it can be designed for various applications. The special design of the walk-in container is ideal for buildings where indoor installation is not possible. It can be placed right next to the building or on the roof, which will not only reduce installation costs, but will also allow easy unit maintenance. For maximum safety, the container is equipped with a special leak detector that responds to gas leaks quickly and lets prevent malfunctions. Additional options, such as illumination, ventilation and cooling can be installed inside the container to make the service of the unit even more convenient.

CO2 Industrial is a customizable transcritical rack, designed mainly for industrial application. Special “reach-in” container option for outdoor installation provides convenient and efficient unit service. This type can be assembled with maximum of 6 reciprocating compressors per stage (MT/LT) and provide cooling capacity ranging from 50 kW to 500 kW. This model is assembled with 6-cylinder compressors, resulting in bigger dimensions and larger power supply.

Such low GWP solutions are designed to have better efficiencies and capacities, as well as less environmental damage.

CO2 Light is perfectly suitable for small food retail stores or gas stations because of its small scale. It can provide up to 50 kW of cooling capacity, split between medium temperature and low temperature refrigeration. These rack systems are designed with reliable refrigeration technologies that are well tested and proven in the market. Assembled with maximum of 3 compressors on a welded frame, made of powder coated steel.

Such low GWP solutions are designed to have better efficiencies and capacities, as well as less environmental damage.

CO2 Compact systems are designed for small retail shops and can be manufactured for medium temperature cooling. Based on Carel HECU system for complete management of condensing units fitted with BLDC compressors, these products can be adjusted remotely. The serial connection between the condensing unit and the evaporators controlled by MPXPRO represents one of the main features of this solution, contributing to the energy efficiency and reliability of the entire system. The built-in plug and play interface provides the ability to install and set up the unit extremely quickly and easily.
