The technologist of a food-producing customer asks about the contents of every material entering the plant; a eutectic plate does not touch the food, but it stands in the same room, so the question is fair. GEBHARDT describes the plate filling as a non-toxic solution of salt and water and the outer shell as food-safe polyethylene. This description applies to the four standard melting points of -3, -14, -18 and -21 °C.
The melting point is set by the kind of salt and its proportion. In the system of table salt and water alone, the lowest melting point is about -21 °C at 23.3 percent salt; that is why the melting point printed on the plate and the closure colour (yellow for -14 °C) read as the identity of the mixture inside.
If a document names a different substance for the -14 °C plate, do not settle the conflict by guessing. Send Aris Makina the plate code, a photo of the label and the date of the document; we obtain the safety data sheet from GEBHARDT and pass it on.
The answer to the technologist is three lines: the filling is non-toxic salt water, the plate sits inside a sealed polyethylene body, and it does not touch food. If the body is damaged and liquid leaks, the product it touched is discarded and the floor is wiped at once because it becomes slippery.
