Three Callisto 100 Share One Cooling Unit

Due to the innovative cooling system of Anton Paar’s Callisto 100 it is possible to run up to three devices simultaneously with only one cooling unit, while fulfilling all requirements of the standard methods.


The Callisto 100 is a fully automated and compact CFPP tester operated by a touchscreen. It contains all required components according to the standard method. Testing and results are in full compliance with ASTM D6371, EN 116, EN 16329, JIS K2288 and IP 309.

The Cold Filter Plugging Point (CFPP) method is used to determine the low-temperature operability of diesel fuel, biodiesel, blends and gas oils. The CFPP is a critical property used to forecast the lowest temperature at which a fuel will freely flow through filters in a diesel engine system.

All diesel fuels contain waxes. When the temperature of the fuel decreases, wax crystals will begin to precipitate at a specific sample-dependent temperature. If a certain amount of wax precipitates, the crystals can block fuel flow through filters and other restricted passages in the fuel system.
