REFRA, UAB - Unique Cooling Solutions

Small capacity air-cooled chillers with the cooling power from 20 kW to 60 kW are perfectly suitable for particularly small commercial applications. CI series chillers are a great choice when low power is required, using the smallest possible frame in order to save space. Air-cooled units are among the most popular when choosing chiller systems, making it a well-crafted product that can meet the regular needs of the customer. Refra manufactures modern devices using plug-and-play ideology, making the installation and use of the devices as easy as possible. In this case, the customer can start using the device quickly and easily after installment. Ultra-compact frame construction is assembled with high-quality EC fan motor technology, scroll or reciprocating compressors and a finned tube or microchannel condenser. The galvanized steel and powder coated frame with a reliable insulation material ensures proper unit protection and noise reduction. An additional 30 mm rock wool material

Medium power range air-cooled chillers with a cooling capacity from 40 kW to 190 kW are designed for commercial and industrial buildings with low to medium power demand. 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. CH series chillers are perfect for integrating propane and free-cooling systems, resulting in highly ecological refrigeration solutions. A built-in reversible heat pump can be installed for both heating and cooling options and better water circulation. Refra manufactures modern devices using plug-and-play ideology, making the installation and use of the devices as easy as possible. In this case, the customer can start using the device quickly and easily after installment.

High power air-cooled chillers with the cooling capacity of 70 kW to 800 kW are designed for industrial and commercial buildings with large power demand. Such systems are widely used in various factories, immense supermarkets and warehouses. With high cooling capacity and many possible extra features, CW chillers stand out as one of the most versatile products that Refra can offer. Special modular assembly system provides extensive power selection options and the ability to integrate a wide range of useful solutions such as a built-in hydraulic module, additional water storage tanks, free cooling or heat recovery options. CW chillers can be made with two to five 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. Refra manufactures modern devices using plug-and-play ideology, making the installation and use of the devices as easy as possible.

Extra large capacity air-cooled chillers with the cooling power of 120 kW to 1400 kW are designed for immense industrial and commercial buildings with high-power demand. CF series chillers are able to provide the highest cooling capacity of all the chillers produced by Refra. The intricate design of the open frame makes it possible to produce a unit with extremely powerful, high-quality parts. These units can be assembled with a built-in hydraulic module, as well as additional free cooling (possible with hybrid coils) or heat recovery options. Exposed frame construction and special perforated doors provide greater air movement and absorption, so the chiller can operate at high capacity without interruption. Two to four circuits can be added 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 liquid-cooled chillers with a cooling capacity from 25kW to 600 kW are designed for a wide range of commercial and industrial refrigeration or air conditioning applications. Designed for indoor installation, CB chillers are manufactured on a compact frame that can be easily transported through standard doors. CB liquid-cooled chillers are built on a closed, assembled frame and equipped with scroll or reciprocating compressors as well as BPHE condenser and evaporator. An additional 50 mm rock wool insulation can be supplemented for a super silent unit operation. On request, these units can be equipped with a buffer tank of up to 800 liters or a hydraulic module. Refra manufactures modern devices using plug-and-play ideology, making the installation and use of the devices as easy as possible. In this case, the customer can start using the device quickly and easily after installment.

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.

High capacity liquid-cooled chillers with the cooling power up to 2 MW are designed for immense industrial and commercial buildings with high-power demand. The special design of the walk-in container is ideal for buildings where indoor installation is not possible. These chillers 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. Additional options, such as illumination, ventilation and heating can be installed inside the container to make the service of the unit even more convenient. Modular assembled container size ranges from 2,4 meters to 13 meters in length and can be insulated with polyurethane foam or 50 mm rock wool material for a super silent unit operation. On request, these units can be equipped with supplementary hydraulic module inside the container and a dry-cooler on top of it.

Medium power range condenserless chillers with a cooling capacity from 25kW to 600 kW are designed for a wide range of commercial and industrial refrigeration or air conditioning applications. These chillers are mounted with a separate remote condenser that is built outdoors. The rest of the equipment is installed in a special technical room in the building. Refra can offer a condenserless chiller that can be connected to an existing condenser or a complete system with Refra condensers. CB chillers are built on a closed, assembled frame and equipped with scroll or reciprocating compressors. These chillers are manufactured on a compact frame that can be easily transported through standard doors. An additional 50 mm rock wool insulation can be supplemented for a super silent unit operation.
