ACS allows a year-round use of swim spas by reducing heat loss and evaporation. The automatic cover is activated by the push of a button and is suitable for swim spas with a length of up to 5.5 metres. The fully integrated mechanism for opening and closing even the lateral shaft allows for the use of new materials, including sheet metal painted in any RAL colour. The minimalist overall appearance adapts to the given architecture of the house and the ambience of the garden.
