The CEE floor tank 6620A consists of a housing made of stainless steel 1.4301 (3 mm) and a 20 mm thick cover made of anodized aluminum that can be closed with a tool. When closed, the CEE floor tank is not waterproof. In the outdoor area, a drainage pipe must be provided on site for the housing to be drained. Due to the surface load of 6.5t, this version can be driven on with a truck if it is properly installed and the lid is completely closed. The lid opens with the help of a gas pressure spring and can be closed with plugged-in plugs. Other equipment variants on request.
