A computer-implemented method for determining a delivery volume for use in a vehicle washing system. The method includes reading in a container data record for the container from which the substance is to be delivered by means of the dosing pump; reading in a digital level value representing a level measured in the container by means of at least one analog level sensor or reading in a digital pressure value representing a pressure measured in the container by means of at least one analog pressure sensor and reading in a digital density value for the substance to be delivered by the dosing pump, determining and outputting the delivery volume delivered by the dosing pump in a measuring time interval, based on the read-in digital level value or the read-in digital pressure value and the read-in density value and on the basis of the read-in vessel data record.

An automatic generation of washing programs for an automatic vehicle washing installation is provided. For this purpose, a washing program generator with a washing program generation unit is provided. This includes an input interface for reading-in an equipment data set which represents how the washing installation is currently equipped with machine components, a processor unit for computation of a group of function blocks based on the equipment data set read-in via the input interface, a user interface which is intended for outputting the group of function blocks computed by the processor unit and is intended for detection of a selection of the output function blocks, wherein the processor unit is further intended to compute a washing program based on the detected selected function blocks for operation of the washing installation.

Wash configurator

An apparatus and method for treating a plastic molded article. The apparatus includes a treatment chamber that can be closed and temperature-controlled. A vapor generating unit generates vapor of a treatment liquid. A fluid connection between the treatment chamber and the vapor generating unit feeds vapor to the treatment chamber and returns condensate back to the treatment chamber. A pressure equalizing device transfers waste air at atmospheric pressure and equalizes pressure with the atmospheric pressure during treatment. The pressure equalizing device retains vapor and prevents vapor from escaping into the atmosphere. A vapor phase is generated by heating a treatment liquid to its boiling point. The treatment liquid includes a solvent that dissolves or solubilizes the plastic. The article is exposed to the vapor phase for a predetermined time and removed from the vapor phase. Residual treatment liquid present on the article is removed.

A foam generator, in particular for a motor vehicle washing installation, includes a foam generation chamber having at least one inlet for water, surfactant and gas, in particular compressed gas, and one outlet for foam, and contains a fluid-permeable bed of loose particles. The bed fills the foam generation chamber sufficiently to prevent fluidization of the bed.

Foam generator

A method for cleaning vehicles by means of which the formation of marks caused by drying is prevented. The method comprises a rinsing step using water. In the method, the anions forming poorly soluble salts with alkaline earth metals dissolved in water are removed from the water, while cations causing the water hardness are retained. Furthermore, a vehicle washing system includes: at least one application device for applying rinsing fluid to a vehicle to be cleaned; and an ion-exchange device for removing anions from the rinsing fluid prior to the application to the vehicle.
