FOAM Flucon Oil Aeration Machine

Our new FOAM (Flucon Oil Aeration Machine)

When fluid aeration is a challenge, FOAM may be your solution.

The appearance of entrained gas in operating media such as lubricants or hydraulic oils can cause functional problems and even damages in many technical applications. As a consequence to the general pursuit of maximum compactness and efficiencies, operational fluids are exposed to growing strains, which increases the risk of entrained air accumulating in the medium. Aerated oils lose their lubricity and get compressible, which may cause serious tribological problems or even damage to power-transmitting components.

flucon, who have become a top-notch expert in the field of fluid aeration ever since we developed the CGS inline aeration meter over a decade ago, have now created an all-new apparatus for the controlled introduction of air into non-conductive fluids, allowings customers to counteract the problems arising from trapped gas in their lubricated or hydraulic systems.

Since this was a completely new field of research, flucon were supported by ZIM, a German government funding program for exceptional innovations. In addition both the procedure and the apparatus are now patented!


The latest innovation from flucon:

FOAM Oil Aeration Machine

Our FOAM (Flucon Oil Aeration Machine) is a compact aggregat which contains a 40 Liter tank (type FOAM S), that can be easily integrated into your fluid circuit as a reservoir, where it then produces consistent air-in-oil dispersions.

If you favor an external installation, with an aeration unit added to your pre-existing open reservoir, you may prefer our FOAM XL-x, which we also recommend if higher flow rates of up to 60 l/min (15 gpm) of aerated oil are required. If you need even more than that, we also offer extra-large custom FOAM units.

No matter what type of FOAM you prefer: Aeration testing is very easy with this plug-and-play unit. Simply set up a gas concentration (CG set = 0.50 - 25.00 vol.-%*) for your specific oil. The FOAM will immediately add the desired amount of dispersed gas to your fluid. This procedure will be carried out fully-automatically, with no compressed air supply required. When the gas concentration reaches the required level the "FOAM ready" lamp lights up and you can go ahead and pump the aerated oil through your circuit.

Of course both the natural degassing and the strain of your application may reduce the gas concentration of your fluid when it is fed back from your outlet to the reservoir. But the automatic degassing compensation function based on inline CG measurement takes care of that: once the FOAM has been calibrated on the fluid of your choice, it constantly measures the live gas concentration inside your tank and intelligently inserts additional air to keep the CG on a constant level. The integrated sight glass (FOAM S) visualizes the dispersion and lets you keep an eye on the homogeneity of your two-phase mixture.

The temperature control compensates for the heat which is generated through the aeration process. If you go for our FOAM S you can also heat up the oil in preparation for your tests by means of its built-in 3 kW heater.
