The CO2 vertical rack is constructed as a single unit on a powder coated steel frame. Vertically build to reduce the footprint, this product has a sufficiently high power potential. This is the unit with the highest power capacity per square meter. Therefore it is ideal for the demands of small food retail stores. Vertical rack system is designed with a well-known refrigeration technologies that have been reliably tested. This frame can be assembled with maximum of 4 compressors and manufactured for medium and low temperature cooling, providing up to 75 kW of refrigeration capacity. GREEN SOLUTIONS | This unit is a part of Refra‘s environmentally friendly product group, as it is made using CO2 refrigerant. 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. GREEN SOLUTIONS | This unit is a part of Refra‘s environmentally friendly product group, as it is made using CO2 refrigerant. Such low GWP solutions are designed to have better efficiencies and capacities, as well as less environmental damage.

Refra manufactures pump stations for waterloop systems with the cooling capacity from 30 kw to 250 kW. These systems produce distributed cooling at different temperatures with a single condensing water loop. Together with Refra pump stations, the system creates a fully integrated refrigeration technology that eliminates the need for complex refrigeration systems and greatly simplifies installation work. Built on a super slim assembled galvanized steel frame with powder coating. Standard selection includes single or dual pump with inverter, glycol tank with filling pump, shut-off valves, control board with controller and necessary control sensors as well as a three-way valve, manometers and a coarse cleaning filter. Extra features, such as emergency heat exchanger with full controls or bubble filter separator can be combined. An additional heat recovery pump can also be added to extract maximum efficiency from the system.

High power reversible heat pumps with the heating power from 100 kW to 400 kW are designed for industrial and commercial buildings with large power demand. Manufactured using R290 refrigerant only and full-inverter technology the units are a part of the extremely economical and environmentally friendly Refra product line. With high cooling capacity and many possible extra features these products are widely used in various factories, immense supermarkets and warehouses. These pumps can be used for heating purposes at ambient temperature of -15°or higher as well as for cooling purposes with the capacity of 70 kW to 280 kW. This dual solution is very efficient in terms of price, installation and space, as there is no need to install two separate systems. CJ heat pumps can be made with one to three circuits to ensure continuous system operation in case of emergency – if one circuit is damaged, the others can still use the remaining unit capacity to service the end user.

Medium power range reversible heat pumps with the heating power from 50 kW to 180 kW are designed for commercial and industrial buildings with low to medium power demand. Manufactured using R290 refrigerant only and full-inverter technology the units are a part of the extremely economical and environmentally friendly Refra product line. These pumps can be used for heating purposes at ambient temperature of -15°or higher as well as for cooling purposes with the capacity of 35 kW to 126 kW. This dual solution is very efficient in terms of price, installation and space, as there is no need to install two separate systems. One of the main advantages of this unit is the possibility to add two circuits, which will provide maximum operational safety by ensuring continuous system operation in case of emergency. If one circuit is damaged, the other can still use 50% of unit’s capacity to service the end user.

Small capacity reversible heat pumps with the heating power from 20 kW to 50 kW are designed for small commercial or industrial applications. Manufactured using R290 refrigerant only and full-inverter technology the units are a part of the extremely economical and environmentally friendly Refra product line. These single circuit heat pumps can be used for heating purposes at ambient temperature of -15°or higher as well as for cooling purposes with the capacity of 14 kW to 35 kW. This dual solution is very efficient in terms of price, installation and space, as there is no need to install two separate systems. Ultra-compact frame construction is assembled with high-quality EC fan motor technology, scroll or reciprocating compressors and a finned tube or microchannel condenser. To prevent ice formation, the frame is equipped with special water drain outlets, which are required to ensure a proper defrosting process.
