Crates washing machine KOMPO-AQUA 400

Crates washing machine KOMPO-AQUA 400


KOMPO-AQUA 400 universal machine is designed for automatic washing of technological containers. Suitable for boxes and trays with overall dimensions: length - from 500 to 830 mm, width - from 355 to 400 mm, height - from 90 to 350 mm. Replaces traditional manual washing. The process of washing and rinsing containers with KOMPO-AQUA increases efficiency and productivity of the washing area. The unit is convenient and easy to operate. The machine switches on and off automatically. There are windows in the machine body that allow controlling the washing process. The process automatic functions save energy and detergents, shorten the washing and rinsing time. Using the control panel, you can smoothly adjust the performance indicators for washing objects and detergents temperature. All data on operation and status of the machine are displayed on the control panel display. Quality of washing with different degrees of contamination of containers is always high.



Location of the loading/unloading tray mechanically limits access to the hazardous area.

Locations of the electrical components on the machine are protected from water ingress by sealed covers.

The machine allows for manual adjustment of the angle of direction of water jet of the nozzles. This ensures washing of especially contaminated areas of containers. 

Detergent tank is thermally insulated, which ensures more economical use of energy resources.

The machine consists of the upper and lower housings. The upper housing contains the washing system, rinsing system and the conveyor motor for moving containers through the tunnel. The lower housing contains the detergent solution tank, circulation pump, power cabinet and mechanical cleaning filter.


The washing system is a closed cycle of washing, during which the detergent solution from the tank is supplied to the collectors of the washing chamber by means of a circulation pump. After washing the container, the detergent solution flows back into the tank, passing through the mechanical cleaning filter. 


The rinsing system uses drinking water which flows directly from the water supply network through the inlet to the rinsing collector, nozzles, washable containers, and then partly into the detergent solution tank and partly into the drain.


The machine conveyor is a chain that moves along a chute in the washing and rinsing chambers. There are protrusions at a certain distance on the chain through which the container moves along the tunnel. The conveyor is driven by a geared motor located outside the working washing and rinsing area. The drive motor is frequency-controlled.


Trays serve for loading and unloading containers. Branch pipes - for connection to exhaust ventilation.

The windows are designed for visual control of the washing process and for servicing the machine: adjusting the nozzles, cleaning the washing and rinsing chamber from debris and dirt, cleaning the tank and heating elements (heating elements and steam collector).


  • Electric heating
  • Steam heating
  • Combined heating


The tank is heated and replenished with the detergent solution. Heating can be electric (using heating elements) and steam. The tank is filled with water through the inlet. Waste detergent solution is drained from the tank through the drain manifold.


The circulation pump is used to pump the detergent solution into the washing system.


The power cabinet contains electrical equipment, with the help of which operation of the washing machine is controlled. The main power switch is used to switch on machine.



The objects to be washed are fed onto the loading tray one after the other along the movement of the conveyor chain. By means of the hooks located on the conveyor, they move along the tunnel.


  • Washing
  • Rinsing
  • Delivery to the tray


  • The first stage of processing is washing the items with a special solution in the washing section.
  • The second stage in the end of the tunnel is rinsing of containers.
  • After washing and rinsing, clean items are delivered to the output tray, from where they are removed by the operator.


Using the control panel, you can smoothly adjust the performance indicators for washing objects and detergents temperature. All data on operation and status of the machine are displayed on the control panel display.


The machine is equipped with opening inspection windows that allow controlling the washing process, and visually monitoring clogging of the mechanical cleaning filter, nozzles and direction of the jets. When the inspection window is opened, the operator is given access to the washing chamber and setting its mechanisms. Maintenance of the machine consists in periodic inspection of the condition of the injectors and their cleaning from possible clogging.


The unit switches to operating mode when the tank is filled with the detergent solution, the required temperature and concentration of the detergent solution are reached. Operating modes must be set on the control panel.

Two mechanical cleaning filters are used to clean the detergent solution from dirt in the machine. The first filter cleans the detergent solution as it flows from the washing chamber back into the tank. The second filter is located in the tank at the suction inlet and cleans the detergent solution before it is sucked into the centrifugal pump from elements that were not retained by the first filter.



  • high-quality, efficient and convenient washing and rinsing process;
  • the presence of automatic functions saves energy and detergents and shortens the washing and rinsing time;
  • different design versions depending on customer's needs, warming of detergent by various methods (steam, electricity, hot water);
