Select the right cleaner
Soiling classification systems determine the mechanical cleaning power required for effective cleaning. We have defined four soiling classes to describe the degree of mechanical force that should be used and the recommended type of cleaners.
Increasing the mechanical element allows the other elements – chemical, temperature and importantly time and liquid consumption – to be reduced.
The dynamic Sinner’s circle shows the interchange between the various elements of cleaning operations.
Using the dynamic Sinner’s circle as a guide, you can determine the best approach to any cleaning application. The percentage of the four elements that make up the circle will vary from application to application and will have a direct influence on the liquid volume shown at the center.
Soiling Class I - Rinse cleaning
Easy cleaning conditions
Water-soluble products with little or no tank adhesion
Recommended: Static Cleaners
Spray balls are perforated spheres made of stainless steel. They present a simple and efficient solution to provide a uniform omnidirectional cleaning effect without any moving parts.
Your benefits with GEA
- Minimal capital investment
- No maintenance required
- Large selection of spray patterns, materials and surfaces
Soiling Class II - Low impact cleaning
Moderate cleaning conditions
Water-soluble products with low adhesion
Recommended: Free Rotating Cleaners
Free rotating cleaners are characterized by their fast rotation around a single axis. Rotation is driven by the liquid flow which produces a range of small to medium-sized fast moving droplets to produce a mechanical force on the vessel walls.
Your benefits with GEA
- Extended life cycle with no servicing
- Selection of spray patterns
– 360, 180-T (towards inlet), 180-A (away from inlet) - Compact effective designs
Soiling Class III - Medium impact cleaning
Difficult cleaning conditions
Stubborn residues with medium tank adhesion
Recommended: Slow Rotating Cleaners
GEA’s slow rotating cleaners use targeted flat or round jets to project the cleaning solution onto difficult-to-clean vessel walls. These units operate at higher liquid pressures but maintain slow rotation to increase dwell time and achieve greater cleaning forces than traditional free rotating units.
Your benefits with GEA
- Effective cleaning with efficient jet design
- Extended service life thanks to hydrodynamic bearings
Soiling Class IV - High impact cleaning
Highly difficult cleaning conditions
Encrusted or dry products with high adhesion
The extensive range of orbital and index cleaners from GEA offers highimpact solutions for the most difficult-to-clean applications. Both model ranges benefit from GEA’s solid stream nozzle technology for optimum spray jet projection and cleaning power.
Recommended: Orbital Cleaners
Our orbital cleaners work on two rotating axes, both horizontal and vertical, along a predetermined path creating a tight 3D matrix.
Your benefits with GEA- Reduced contamination with hygienic design
- Cost-effective
- High impact cleaning
- Low service costs
Recommended: Index Cleaners
GEA’s unique range of index cleaners provide highly effective cleaning performance through their piston operated index mechanism. Large amounts of energy can be applied by the slow moving operation, directly onto the vessel walls.
Your benefits with GEA- Design maximizes cleaning power to jets
- Piston drive offers jam-free operation
- Longer intervals between services
