Aqualand Moravia is one of the most important tourist destinations in South Moravia and a popular place for all lovers of adrenaline and swimming. Its sophisticated outdoor and indoor part offers several interconnected pools (classic and thermal), a giant wellness and a large number of water attractions. As part of this year's reconstruction of air conditioning systems, we delivered AeroMaster Cirrus, AeroMaster FP and CAKE air handling units with a total air output of more than 235,000 m3/h with our own measurement and control system. The technical specialty of the delivered units is the integrated compressor cooling and dehumidification system for year-round operation. The largest part of the delivery consisted of central equipment designed for operation in environments with increased humidity and increased concentrations of chlorine and geothermal water substances. Therefore, we placed great emphasis on, among other things, the material design of the casing and all other components of the units.
