Precise Temperature Control for Accurate Measurement Technology
When analyzing fluids under real-world conditions, flucon believes that the quality of measurement technology depends entirely on the quality of temperature control. This commitment makes JULABO’s precise temperature control systems an integral part of many flucon setups.
The analysis of fluids under real-world conditions is the core business of flucon fluid control GmbH. Based in Niedersachsen, Germany, this medium-sized company develops and supplies highly specialized measurement systems for investigating fluids in realistic environments – from oils and greases to coolants and paints.
Simon Hausner, CTO of flucon, puts it succinctly: “Our core competence is the analysis of fluids – everything that flows.” For Hausner, the quality of measurement technology is only as good as the quality of temperature control. This belief makes precise temperature regulation an integral component of many flucon systems.

Why is flucon a strong partner for precise fluid analysis under extreme conditions?
A key differentiator: flucon is not only a developer and supplier of measurement instruments – it also uses them in its own laboratory and offers laboratory services directly to customers. This practical user perspective makes flucon a true partner at eye level and drives the continuous optimization of its systems. A particular highlight is the company’s in-house high-pressure laboratory, where material properties can be analyzed under extreme conditions of up to 1.4 GPa (14,000 bar) – a key prerequisite for accurately assessing fluid behavior under real loads.
What is the key to reliable measurement results?
Accurate data requires more than sophisticated sensors. Equally important is precise temperature control – and this is where flucon relies on JULABO technology. Devices from the CORIO and MAGIO series ensure highly accurate temperature management, provide stable conditions for reproducible measurements, and meet modern connectivity requirements, such as RS232 interfaces.
How does flucon combine static and dynamic methods for more precise lubricant analysis?
At the heart of flucon’s current development approach is the so-called Dual Approach – an innovative concept that combines the static Epsilon+ method with the dynamic analysis capabilities of the E-Lub Tester.
The Epsilon+ examines the electrical properties of oils and greases under constant conditions. This is particularly relevant in electric drivetrains, where electric fields affect the lubricant film. Epsilon+ helps determine whether the lubricant conducts or insulates – and whether there's a risk of electrical breakdowns. For this application, flucon relies on CORIO and MAGIO range of circulators from JULABO.

The E-Lub Tester, in contrast, focuses on dynamic processes. Bearings filled with oil or grease are electrically analyzed under variable conditions such as speed, axial load, and temperature. Heat is generated through compression in the lubricated contact. MAGIO refrigerated circulators offer a strong pump performance, ensuring rapid heat dissipation and a stable testing environment.

What matters most to flucon in a technology partnership?
Service is a crucial factor for flucon when choosing a partner: technical and organizational queries are often answered by JULABO on the same day. For specialized inquiries – even those beyond manuals and standard documentation – an experienced expert is quickly made available.
Another important aspect of the partnership is the shared commitment to sustainability. flucon also considers environmental compatibility when selecting temperature control devices – for example, by using natural refrigerants, as provided in JULABO’s refrigeration circulators.
flucon and JULABO – a success story that shows what’s possible when precision meets mutual trust.
