A device and a method for ejecting a fluid are provided. The device comprises a main pipe, a rotatable housing connected to the main pipe and a hub provided with a nozzle. The hub is rotatably connected to the housing. The fluid is arranged to be conveyed through the main pipe and the housing to said nozzle for ejection of the fluid, and the hub is arranged to rotate about an axis arranged with an angle in relation to a longitudinal axis of the main pipe. The angle between the axes is arranged to vary between 90 and 90+, 245, when the housing rotates one revolution.

A monitoring arrangement monitors the operation of a cleaning-in-place system which is operable to remove contaminations, deposits and other impurities from the internal walls of a container. The CIP system comprises a pipe for extending into the container through a wall portion of the container, and a nozzle head for ejecting liquid into the container in a predetermined pattern. The monitoring arrangement comprises a sensor unit with a sensing surface responsive to liquid impact for enabling the sensor unit to emit a sensor signal indicative of the liquid impact. The sensing surface is elongated and configured to extend along a perimeter of the pipe when the sensor unit is mounted at the wall portion of the container. This enables improved performance of a processing unit that obtains and processes the sensor signal for monitoring the operation of the CIP system.

A cleaning device including a housing which can be arranged on a feed line for cleaning fluid is disclosed. The housing includes an exit opening for the cleaning fluid, wherein a nozzle head rotatable about a first rotary axis is arranged in the region of the exit opening. A distributing device rotating about a second rotary axis different from the first rotary axis and having at least one blade element or at least one pendulum element is arranged on the rotatable nozzle head. The invention also describes a product-processing plant with at least one cleaning device for cleaning a product tank.

A high pressure surface cleaner includes a housing having an open end, a high pressure coupling in fluid communication with the housing and having a first end and a second end, the first end configured to receive a high pressure water source, and a supply conduit rotatably secured to the second end of the high pressure coupling and configured to rotate about the high pressure coupling defining a horizontal plane within the housing. The cleaner also includes first and second nozzles having a vertical axis therethrough and secured proximate to the first and opposing second ends of the supply conduit, respectively, the vertical axis of the first and second nozzles approximately normal to the first horizontal plane, and a directional nozzle coupled to the supply conduit and having a directional outlet orientated to cause the supply conduit with the first and second nozzles to rotate when discharging water.

Washing equipment for a vehicle includes at least one gantry defining a track for the vehicle, at least one nozzle supported by the gantry and intended to spray a cleaning liquid on the vehicle, and a helical profile that creates a helical rotational movement of the cleaning liquid relative to the gantry. The helical profile is suitable for ensuring the rotation of the cleaning liquid around the axis of the stream of cleaning liquid leaving the nozzle.

A method to deliver high velocity air from a rotating nozzle manifold which continuously passes through multiple rotational axes so as to project the nozzle discharge air into virtually every spherical direction in order to impact all surfaces on or within a structure. With the use of two rotating air couplings operating in series and each fastened to their own air manifolds, and having small thrust jets on each manifold powered by the same pressurized air supply used for the high velocity discharge nozzles, rotation of the high velocity air nozzle manifold in the X and Y axes are achieved.

A high pressure surface cleaner includes a housing having an open end, a high pressure coupling in fluid communication with the housing and having a first end and a second end, the first end configured to receive a high pressure water source, and a supply conduit rotatably secured to the second end of the high pressure coupling and configured to rotate about the high pressure coupling defining a horizontal plane within the housing. The cleaner also includes first and second nozzles having a vertical axis therethrough and secured proximate to the first and opposing second ends of the supply conduit, respectively, the vertical axis of the first and second nozzles approximately normal to the first horizontal plane, and a directional nozzle coupled to the supply conduit and having a directional outlet orientated to cause the supply conduit with the first and second nozzles to rotate when discharging water.
