blast chiller!!!!

what could i use a blast chiller for in my pizza / bbq shop have no clue but my dad bought one today at a casino auction its two years old and works fine.did a little research but still little unsure anyone using one of these

Blast chillers are great!!! They do what they claim…blast chill! Pull the bbq from the pit and put it in the chiller it will rapidly cool the pork, then hold it at safe temperature till your return…ie the next morning. It also prevents you from putting warm food in the walk in and lowering that temp. Wish I still had one.
