FOAM Flucon Oil Aeration Machine

Our new FOAM (Flucon Oil Aeration Machine)

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

The appearance of entrained gas in operating media such as lubricants or hydraulic oils may cause functional problems and even damage in many technical applications. As a consequence to the general pursuit of compactness and high efficiency, 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 two-phase flow testing ever since we developed the CGS Inline Aeration Meter over a decade ago, have designed a reliable and patented test rig 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.


flucon's latest innovation: FOAM Aeration Test Rig

FOAM (Flucon Oil Aeration Machine) is a compact aggregat which can be connected to your test tank (FOAM XL-x version) where it then produces consistent air-in-oil dispersions.

If you favor a stand-alone test rig with an integrated heatable 40 Liter tank, we recommend the FOAM S version. If more than 60 l/min (15 gpm) of aerated oil are required, 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 the gas concentration (CG set = 0.50 - 25.00 vol.-%*) for your specific oil. The FOAM will add the desired amount of dispersed gas to your fluid promptly. This procedure will be carried out automatically, with no compressed air supply required. Once the gas concentration reaches the required level the "FOAM ready" lamp will light up and you can go ahead and pump the aerated oil through your circuit.

Since both the natural degassing and the consumption of your test application will reduce the gas concentration of your aerated mixture, there is an automatic degassing compensation based on live CG measurement. After 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 the FOAM S you can also heat up the oil in preparation for your tests by means of its built-in 4.5 kW heater.
