The Coaxial-Shear Cold Finger cCF6 is a high-performance laboratory device developed to analyze wax deposits and evaluate the efficiency of wax and paraffin inhibitors under realistic shear conditions. It features six rotating cold fingers housed in a temperature-controlled water bath, allowing for simultaneous testing and reproducible results.

A pneumatic lift system simplifies handling by enabling safe and quick access to samples and measuring sleeves—enhancing both safety and efficiency during operation.

With its compact, modular design, the cCF6 delivers exceptional ease of use, accurate measurement, and high flexibility. Its ability to control and replicate shear conditions across all measuring stations makes it ideal for advanced research and quality control in the petroleum and crude oil industries.

The PSL Coldfinger CF 15120 is equipped with up to 15 measuring places for multi-place testing. Combining multiple cold fingers in one heating bath facilitates screenings on wax inhibitors, e.g. simultaneous testing of different chemicals on a single sample or testing of different inhibitor concentrations with the same sample. The Cold Finger can be run with separate temperature control and stirring speed for each rack of 5 measuring places, thus reducing full test procedure for a single sample immanently. The dry bath allows a precise temperature control up to +120 °C / +248 °F.

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.
