Inner tubes - Import export

Refra heat exchangers for evaporators are made of aluminum or copper fins and convert the system’s refrigerant liquid to gas. Usually they are used to cool and sometimes dehumidify air. Refra evaporator coils are made using inner grooved or smooth copper tubes, which range from 7 mm to 12,7 mm in diameter. The operating tube pressure reaches 80 or even 120 bar, making evaporator coils perfectly suitable for CO2 systems. The frame can be made using aluminum, galvanized or stainless steel and can be coated with a special Aqua-Aero anti corrosion protection. Heat exchangers can be manufactured up to 50 kW capacity for both low and medium temperatures.

Wide capacity range air cooled condenser series, Created for small and large refrigeration or air conditioning systems used in commercial and industrial buildings with medium and high power demand. CV series units are ideal when high capacities are required in a limited installation space. This unit is Available heat capacity is up to 1,3 mW under nominal conditions (when Tcond is 45°C, Tamb is 30°C and R1234ZE. V shaped construction, assembled with inner grooved copper tubes, aluminum or copper fins and AC or EC fan motor technology. The galvanized steel and powder coated frame can be designed in various sizes.

Extensive capacity range air cooled condenser series created for large refrigeration and air conditioning systems. Four heat exchangers and double fan row provide immense heat capacity within limited placement area, making it perfect for saving space while still maintaining high power. This type of unit is perfectly suitable for commercial and industrial buildings with high power demand. Available heat capacity is up to 1,6 mW under nominal conditions (when Tcond is 45°C, Tamb is 30°C and R1234ZE. W shaped large construction, assembled with inner grooved copzer tubes, aluminum or copper fins and AC or EC fan motor technology. Galvanized steel and powder coated frame can be designed in various sizes. The clever frame design also allows for the installation of additional equipment under the condenser.

Wide range capacity air cooled condenser series, perfectly suitable for small and large refrigeration and air conditioning systems used in commercial or industrial buildings with low to high power demand. Due to its lightweight construction and practical weight distribution this product can be installed even on medium-strength rooftops. Available heat capacity is up to 800 kW under nominal conditions (when Tcond is 45°C, Tamb is 30°C and R1234ZE. Flat shaped simple construction, assembled with inner grooved copper tubes, aluminum or copper fins and AC or EC fan motor technology. The galvanized steel and powder coated frame can be designed in flat or vertical way.

Refra heat exchangers for condensers are made of copper tubes and convert the system’s refrigerant gas to liquid form. Usually they are used for refrigeration equipment as a remote condenser or as a part of a condensing unit. Refra condenser coils are made using inner grooved or smooth copper tubes, which range from 5 mm to 12,7 mm in diameter. The frame can be made using aluminum, galvanized or stainless steel and can be coated with a special Aqua-Aero anti corrosion protection. Heat exchangers can be manufactured from low to high capacities to fully meet customer needs.
