They operate with TUNZE® Hydrofoamer 9400.04, which also ensures the water circulation; the open water circulation then reaches a water flow rate of 1,300 l/h (343 USgal./h), 2,600 l/h (686 USgal./h), 3,900 l/h (1,030 USgal./h) or 5,200 l/h (1,373 USgal./h) depending on model. The models 9420 / 9440 as well as 9460 / 9480 have the same technical features, only the number of Hydrofoamers varies. In case of operation in aquarium cabinets, the cartridge core on the outlet pipe ensures bubble-free outgoing water. Skimmer cup and foam reactor are one unit in all TUNZE® DOC skimmers: Every cleaning of the skimmer cup leads to the reactor being cleaned at the same time, and thus a very constant and efficient foam production is ensured. During the cleaning process, the Hydrofoamer remains operational and automatically flushes the air passage.
Delivery condition: Ready to mount; dimensions with the cleaning accessories.
In the skimmer, the TUNZE® Hydrofoamer produces a large
quantity of a mixture of 50 per cent of water and 50 per cent of fine
air bubbles. Each air bubble has an active surface which binds the
electrically charged DOCs (Dissolved Organic Carbons). This airwater
mixture is transported into the reactor area. In the process,
a denser foam mass is produced. The upper zone of the reactor
is used to settle this foamy mass laden with protein, which is then
removed into the foam cup. The purified water returns into the
aquarium without bubbles or into the filter. By means of a special
nipple, ozone can be passed into the system, thus improving the
skimming process and at the same time removing any yellowing
matter in the aquarium water. It can be observed that when air
bubbles are produced proteins are absorbed immediately. In
practice it can be observed that the absorbed matter is torn off the
air bubbles again by skimmers with a high construction. For this
reason, all TUNZE® DOC skimmers have very short reactors with
a high air output.
