To permanently protect the straddle carrier from water damage, all hydraulic tanks on a straddle carrier at Europe’s largest container terminal and logistics group were fitted with adsorbers in a 3-month test. While dirt particles from a size of 3μm are separated, the effect of complete air drying is added.
Depending on the tank size, original GIEBEL Adsorbers® of the VENT-PA series were installed. The air drawn into the tank is thus dehumidified to an initial 2%rh (average 10%rh).
Consequently, condensation occurs only when the temperature falls below -12.5°C. Regardless of what insulation or temperature control the hydraulic tank will have in the future, the hydraulic systems are effectively protected against water ingress from the air and can be operated reliably in all weather conditions.
