Plug play - Import export

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. 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.

High capacity condenserless 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 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. CS Condenserless chillers are assembled on a welded open frame, equipped with maximum 4 screw compressors and shell and tube heat exchangers. They are usually chosen when there are sound restrictions in the project. The louder part of the system is built in an isolated room and the quiet condenser is built on the roof. The whole system is connected by a pipeline for refrigerant circulation and absorbed heat rejection. Refra manufactures modern devices using plug-and-play

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.

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 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.

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
