REFRA, UAB

Lithuania

Smalest size condensing units for commercial refrigeration systems. Units are equipped with scroll or digital scroll compressors designed for MT or LT applications. Unit features are fast delivery time, low sound and easy installation. More options are available for selection in Refra Selection Tool. MT 3-11 kW, LT 3-6 kW

Lithuania

Condensing units are designed to satisfy the needs of medium-sized commercial or industrial air conditioning systems. Our units are equipped with high efficiency scroll compressors and work on R410A refrigerant which does not contribute to ozone depletion. The latest Scroll® compressors provide the highest annual energy efficiency levels, due to ESEER up to 4, along with superior reliability. When combined with EC high efficiency fans and oversized condenser coil the unit delivers the lowest annual electricity bills. Bcase line condensing units are designed for operating in +46°C - +5°C ambient temperature range with basic unit equipment. Also we provide a variety of options which can improve an air conditioning system work.

Lithuania

Open type classic condensing unit with simple and reliable design for small/medium/big size commercial/industrial refrigeration systems. Units are equipped with reciprocating compressors. Unit features are wide capacity range with different compressors and condenser sizes and variety of options available for selection in Refra Selection Tool. MT 15-75kW LT 4-30kW

Lithuania

KWW (Galaxy) condensing units for medium/big size commercial/industrial refrigeration systems. Units can be equipped with different compressors connected in parallel as single circuit or several circuits. Unit features are design flexibility and wide variety of available options like oil & line components, different fans, completely closed compressor compartment, heat recovery that could be offered on request..

Lithuania

KI (Neptun) condensing unit for small/medium size commercial/industrial refrigeration systems. Units can be equipped with single or parallel connected scroll/reciprocating compressors. Air intake from the back and vertical airflow ensures easy servicing possibilities from the front side of the unit.

Lithuania

Units are produced with scroll, digital, reciprocating various speed and screw compressors. Racks could be used in commercial or industrial refrigeration systems. Units could be made for low, medium or high temperature applications. To satisfy customer needs, racks could be assembled on different type of frames or housings: AU - welded frame, bended profile. Advantages: compact and light weight; possible 2-floor design; AB - assembled frame with cover. Advantages: compact and weather proof housing; AS - welded frame, standard profile. Advantages: solid construction; AR - assembled frame. Advantages: could be transformed for inside/outside installations.

Lithuania

Unit usually assembled in 2 floors. On one discharge line could work up to 4 different temperature range compressors. System could be assembled either with scroll either reciprocating compressors.

Lithuania

The other option is using CO2 as the only gas in supermarket systems. This needed a technology that is fundamentally different from conventional refrigeration plant: Transcritical compression. This type of refrigeration system has high energy efficiency Indicators and has GWP=1.

Lithuania

Air cooled condensers are designed to be used in commercial and industrial refrigeration systems. Heat Exchanger is produced with copper tubes and aluminum fins that formed self spacing collars which guarantee the maximum heat transmission and efficiency. We use seamless smooth copper tubes or inner grooved copper tubes to increase heat transfer, nominal tube diameter 3/8”, 5/16’’ or 1/2” depending on heat exchanger. Can be used aluminum fins, aluminum coated fins (epoxy, hydrophilic) and copper fins. The fin spacing available - 1.41; 1.58; 1.81; 2.12, 2.31mm. Fan motors. Axial fans are guard mounted with external rotor motors, insulation class - F, IP54. Single-phase or three-phase fans are used to obtain different sound levels for each available fan diameter. Frame and Casework. The coil casing is formed from heavy galvanized sheet steel, aluminum or stainless steel. The case can be finished with polyester powder paint optionally. Certifications and reliability.
