Refrigerant Flow Controls – Commercial
Features:
High style chrome name plate and logo, a new slick look for the expansion valve
Technical Significance:
The 893 compact thermostatic expansion valve, although short lived, was a significant marker of the times, as the industry, responding and at the same time shaping the market place, moved to ever more compact, more sophisticated engineering designs based on cumulative know how. A sign of the now rapidly changing times, Detroit would soon replace the 893 with the even more compact design, the 777.
Industrial Significance:
High style chrome name plate and logo, a new slick look for expansion valves in the early post W.W.II years, reflecting the new interest of manufacturers in the emerging field of industrial design
The now rapidly changing market place would trigger substantial investments in R and D by companies like Detroit. The life of this product would be a short one, soon to be replaced with an even more compact design, the 777. A sign of things to come.
