Maxicool 100 flash chiller is now in action and can either be connected to a cooling coil around the outside of the fermenter when brewing in the warm summer months or to a similar cooling coil in the second kegerator.
This cabinet is lined with 50mm Kingspan panels and the coil fits around one of the cornies. It provides extra cooling for the beer with the cool!!
