Design and build scientific equipment with critical thermal or fluidic functions

Thanks to its design skills and the manufacturing capacity of the ALCEN group, EPSILON is able to design and produce scientific equipment when these include critical thermal and / or fluidic functions:

  • Test benches : EPSILON develops custom test benches for the characterization of materials, systems or validation of performance
  • Scientific equipment : EPSILON is involved in projects for the design and production of scientific equipment meeting specific needs such as high-precision calorimetry or very low temperature systems

Diphasik - Cooling technology resulting from a partnership with ATMOSTAT

The mechanically pumped two-phase fluid loop is an efficient, innovative and industrial solution that uses latent heat of evaporation as a means of heat transfer operating at a very low thermal gradient.

Our solution is particularly suited to the problems of cooling high-power electronics (space, rail,). The densification of electronic components and the limited yields imply having to solve the problem of heat dissipation at high power density.


  • Closed loop, sealed, pressurized, loaded with two-phase fluid.
  • High compactness of heat transfer.
  • High density of removable power.
  • Fluids suitable for holding wide temperature ranges.


  • Thermal management of high density power electronics and operating in a highly constrained environment.
  • Thermal management of components based on large gap semiconductor materials such as Silicon Carbide (SiC) or Gallium Nitride (GaN).
  • A solution for on-board and / or confined systems such as aircraft, "more electric" vehicles or mobile objects, renewable energies, etc.

DEsProTherm - Equipment for Measuring Thermal Properties

Thermal capacity, effusivity and conductivity of materials (ceramics, composites, etc.)

EPSILON markets equipment for estimating thermal properties based on the hot plane method and offers custom measurement cells to best integrate the specifics of the products.

The hot plane method deployed in the DEsProTherm device is conventional and consists of measuring temperatures on the front and rear of the sample after thermal excitation. The temperatures measured are then used to estimate some of its thermal properties. The innovation of EPSILON lies in the processing of data from thermal excitation which allows us to go back to the desired physico-chemical characteristics. This data processing is the result of several years of R&D in partnership with the CNRS in the field of thermal engineering. This intuitive and user-friendly software uses multiple calculation algorithms to guarantee reliability of the results.

Easy to use, DEsProTherm integrates a set "Electronic module - Power supply - Probes" for thermal excitation and acquisition.

The sample is placed on an instrumented resistive circuit and the temperatures are measured by thermocouples. The measurement is fast, non-destructive, and requires only the positioning of the sample.

DEsProTherm is suitable for a wide range of materials: conductors, insulators, metals, ceramics, minerals, fabrics, etc.

It offers a measurement range from ambient to almost 500 °C.

The device is adaptable to your needs (ranges, measurement temperatures, probes, etc.) and transferable to an industrial environment (control on a production line, etc.).
