A lot has already been written about this topic, but still a small report of my experience. During the winter my CLS is hardly driven, but at 85% humidity in the garage (double-parker) this is not the ideal ‘place of storage.` Despite 30cm Maico fans, otherwise the humidity would probably increase. So I took care of a dehumidifier. First of all I looked for dehumidifier performance and of course after the price. But at some point I wondered how Because the parts, which work according to the condensation principle, should dehumidify 5 degrees cold garage air. This probably only works badly or not at all. At the company Trotec I then found: a dehumidifier, which works according to the adsorption principle and is explicitly intended for cold rooms. Costs at the moment € 169,00 including shipping costs, directly from the manufacturer. (TTR 55 E) I installed this yesterday and after about 18 hours of operation the humidity dropped from 85 % to moment 62% with further downward trend. The garage has a volume of at least 60 m3. PS in the interior / trunk I use a 1kg-Sack Silica gel each.
