Collin's refrigerators, powered by a two-piston expansion engine, provided the first reliable supplies of liquid helium in quantities of several hundred to several thousand liters.[4][5] Among other uses, these refrigerators were used to liquefy and transport helium and deuterium for the first hydrogen bomb explosion, Ivy Mike in 1952.[6]

He was awarded the John Price Wetherill Medal in 1951 and the Rumford Prize in 1965.
