Ringling had 8 of these wagons from 1939 to 1942 in the front of the wagon was a ice bunker that a huge fan in the rear blew air over the ice and thru a tube that attached to two pipes in the top of the wagon the tubes were also attached to the top of the big top a interesting note is also in the rear was a heating unit so that in cold weather they could heat the tent with the same units
The wagons were numbered 160 to 167 and were 16 and 1/2 ft long 8 ft wide and 10 tall built by Southern Iron and Equipment Co . Buffalo Fordge handled the design and fitting of both the A/C and heating equipment. The Fans were capable of handling 17,000 cu ft of air per miniute and wer driven by GE 3 hp Electric motors Each Ice bunker helt 6.000 lbs of ice and operated on much the same principle as todays evaporative cooling systems.
