Safety

NaK is selected for Danamics LMX due to its very unique thermal characteristics, but alkali metals are known to have very violent reactions - especially with water. Danamics approach to this has been a very unique design, where safety is highly prioritized. Our products are designed in such a way that the NaK is inside a hermetically sealed metallic structure, where it circulates in a closed loop. For the Danamics LMX cooler, Danamics has developed a high tech induction soldering process for manufacturing. The construction elements are joined with metallic soldiering, ensuring the rigidity of the hermetically sealed metal structure.

Another safety measure in the design, is the "neutral" pressure inside the closed loop. The pressure inside the loop is 0.5 bar above ambient pressure, eliminating the possibility of breaks due to high pressure. Also as NaK is incompressible leak from expansion is eliminated.

But what if the product leaks, one might ask? Well simply we don't believe it can. Only by mechanically damaging the product, this would be possible and even that scenario has been taken into account. If the metallic closed loop structure is cut open, only a small amount of NaK will surface. This will coagulate during oxidation which tends to plug the leek preventing additional NaK from leaking out. The coagulation process is actually started by contact with water - more precisely from the moist in our air. NaK exposed to the ambient air can be seen as a grey substance.
