Mixing Container Vessel Washing Machine Serie CS-2

The Cleaning Technology

The CS-2 mixing container cleaning system cleans your mixing and preparation containers inside and outside using a speed-controlled rotating brush with the help of a suitable cleaning agent. Mechanical cleaning using brushes is one of the most effective and efficient cleaning methods; it ensures a residue-free result when combined with a powerful cleaning agent. 

Our cleaning systems are modular in design. Even with the basic version, automatic cleaning operation is possible. Expansion stages and additional functions make our cleaning systems a comprehensive solution tailored to your needs.

Washing and rinsing media for cleaning and washing

With the modular CS-2 mixing tank cleaning system, all washing and rinsing media available on the market can be used up to an operating temperature of 60 °C, with the exception of acidic detergents with a pH value below 5.

Safety when handling detergents and washing-up liquids

If detergents that form explosive aerosols when sprayed or flammable solvents are used during the cleaning process or if there are solvent-containing residues in the container, this area is considered ATEX Zone 0. The inside of the washing area (rotating brushes etc.) is therefore type-tested and certified for use in ATEX Zone 0.

The solids content (2nd phase) in the detergent in our cleaning systems can be up to 8 % by volume, regardless of the conductivity.

Process description basic machine CS-2

The CS-2 has an automatic process sequence. Cleaning times can be individually preselected using a selector switch. The entire process complies with current safety requirements in terms of both personal and system protection.

All process steps take place in the closed washing cabin. This minimises the risk of accidents, as moving system parts are out of the operator's reach. Odour and noise emissions are reduced to a minimum.

 

Expansion stages to the basic system

Upgrade stages are designed to adapt the system to the user's desired conditions or characteristics and integrate it into the existing production process.

Pit Basin

When placing the container on the turntable at ground level, it must be recessed into the floor. With our pit basin, you avoid complicated formwork work and also receive all necessary installations included:

  • Steel sheet pit basin, hot-dip galvanized, compliant with WHG standards with the required connections to the floor
  • Solid angle at the upper edge
  • Built-in supports and guide profiles for the correct positioning of the turntable
  • Integrated leak detection

The pit basin can be delivered in advance or at the appropriate stage of construction.

Semi-Automatic Drain and Valve Cleaning

For optimal cleaning results, the drain must also be cleaned. Depending on the valve system or cleanliness requirements, they should be disassembled, taken apart, and cleaned. Another option is our semi-automatic system:

  • Pneumatic drive with corded shaft and electrically conductive monofilaments
  • Spray and rinse device in the cabin roof

Exhaust Fan

During the overall process, emissions or system overpressure are created due to various chemical-physical processes. With our exhaust fan system, you can direct and control the process air out of the wash cabin:

  • Exhaust fan, painted steel sheet, system performance approx. 1200 m³/h

The exhaust fan is supplied separately and must be installed according to installation instructions.

Aerosol Separator

When spraying heated wash and rinse media, aerosols are created that can settle in the piping system. Direct disposal to the outdoors can result in visually undesirable "steam plumes," especially in winter:

  • Static aerosol separator packed in a ventilation pipe
  • Airflow speed approx. 2 m/s
  • High separation efficiency

The aerosol separator is supplied separately and must be installed according to installation instructions.

Exhaust Condensation System

Especially with warm operating cleaning media, heat creates expansion in the wash room, leading to increased emissions. The integrated condensation system reduces emissions and, depending on the evaporation rate of the detergent, also aids in droplet removal. The separation efficiency depends on the cooling water provided by the operator, the dew point of the detergent used, and the chosen process temperature.

Modular system for on-site assembly at a suitable location, according to our installation instructions.

  • Completely enclosed bundle heat exchanger with condensate collection basin
  • Airflow speed approx. 1.5 m/s
  • Piping system made of galvanized steel, longitudinally welded
  • Aerosol separator
  • Circulation fan
  • Automatic, 4-20 mA controlled exhaust dampers

Container Blowing System

Especially for warm operating, poorly evaporating wash and rinse media, containers should be blown free of droplets in the wash cabin:

  • Separate piping system with special fan nozzles
  • Compressed air tank with approx. 1000 liters capacity
  • Special booster for pressure increase

The system can be connected to your regular compressed air network. Installation is done on-site according to our installation instructions.

Insulated Wash Cabin

Especially for warm operating (over 50°C) wash and rinse media, we recommend insulating the wash cabin:
Rock wool 60 mm
Covering made of aluminum sheet, sealed at penetration points
