The orbital cleaners work on two rotating axes, both horizontal and vertical, along a predetermined path creating a tight 3D matrix which ensures a professional cleaning result.
GEA’s unique range of index cleaners provide highly effective cleaning performance through their piston operated index mechanism. The advantage of this type of cleaner is that large amounts of energy can be applied by the slow moving operation, directly onto the vessel walls.
The cleaning of vessels within soiling classification I requires a liquid distribution which delivers large volumes of fluid simultaneously over the complete vessel. Static spray balls offer very little mechanical force so they rely on the liquid running down the vessel walls to create surface friction or to dissolve the residues from the production process.
Free rotating cleaners are characterized by their fast rotation around a single axis. This 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 and thereby a professional cleaning result.
Slow rotating cleaners use targeted flat or round jets to project the cleaning solution onto the vessel walls. These units operate at higher liquid pressures than traditional free rotating units but, because of their design, maintain controlled rotation speeds. This enables these devices to impact greater cleaning forces onto the vessel walls than the free rotating units. As the rotation is kept under control, the spray jets have an increased dwell time, providing even more cleaning power. The slow rotating units from GEA are an efficient and cost-effective solution for stubborn and difficult to clean vessels in numerous industries.
A special sensor system is integrated in the tank when orbital cleaning heads are used to verify the cleaning process. In this system the medium jet hits the sensor at regular intervals. The signals issued by the sensor can be used to monitor the function of the cleaner electronically and to profesionally document the successful cleaning process.
The retractor In-Line Sprayer IS 25 offers a unique and highly valuable method of cleaning vessels and pipe work where a cleaning head cannot remain inside when the process is running. Its design makes the In-Line sprayer IS 25 in particular suitable for the cleaning of tanks with moving components, such as agitators and scrapers.
