Heating installations - Import export

Wide capacity range dry cooler series, created for small to large refrigeration systems with high power demand. Complete with a double heat exchanger and single/double fan row, this product is a super effective solution, which can provide large heat capacity while being installed in limited space area. For these reasons it is a popular choice for medium to large size commercial and industrial buildings. Available heat capacity is up to 550 kW under nominal conditions (when ETG is 35%, Tin is 45°C, Tout is 40°C and Tamb is 35°C). Capacities up to 1.2 mW can be achieved by ordering a modular DV type with more heat exchangers that are tilted to the side and reduced in length. V shape construction, assembled with smooth copper tubes, aluminum or copper fins and EC/AC fan motor technology. The galvanized steel and powder coated frame can be made in various sizes.

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 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.

Our company’s employees use equipment specifically designed for this purpose – the extractor – to carry out complex dismantling and installation operations of heat exchanger bundles on a daily basis with a sufficient level of quality and safety. It is important to note that the professionals at KERTEX Energija are certified by the extractor manufacturer Peinemann Equipment B. V.
