In refrigerating brines, chromates at a pH of about 8-8 5 have been widely used. Concentrations recommended are between 2 000 and 3 300 p.p.m. corresponding to the 125 and 2001b (56-7 and 90-7 kg) of sodium dichromate per I 000 ft (28-32 m ) for calcium or sodium chloride brines, respectively, recommended by the American Society of Refrigerating Engineers. 

Cryo engineering differs from refrigeration engineering in that the temperatures involved in cryo engineering are in the range below 120 K (< -153 °C). Here we are dealing with two questions ...
