^{_{Laboratories and research achievement:}}TRA 200 water cooler and ECH 100 exchanger, for Laboratoire des 2 infinis

Assembly of a unit including a TRA 200 water cooler, associated with an ECH 100 end-of-line heat exchanger (allowing the circuit to be decoupled for optimal antifreeze management) for the Laboratory of Physics of the Two Infinities.

In this group of research laboratories (a joint unit of the CNRS, the University of Paris-Saclay and the University of Paris-Cité), the cooling unit will be used in particular to cool a Cryo compressor.

A partnership that honors us, and obliges us to maintain our best quality standards daily.
