JANKA belongs to the traditional producers of the air-handling units, ventilators, industrial coolers and heat exchangers. The company with its production halls are based in the outskirts of Prague. Thanks to our regional offices and distributors we are present in the Czech republic as well as in other European countries. Division of the Industrial Coolers JANKA ENGINEERING s.r.o. is one of the leading producers of industrial coolers specialized on various types of heat exchangers. These products are used as parts of a variety of machines employed in the industry, energy industry, railway and shipping transportation (e.g. coolers in locomotives, diesel engines, transformers and turbo generators). The exchangers are generally designed for the indoors. However selected products comply with outdoors conditions, explosion prove and also with applications with required seismic resistance. To our business partners such companies as ŠKODA PLZEŇ, ČKD, ALSTOM POWER PBS, ZOS ZVOLEN, SIEMENS, BRUSH SEM belong.
