Made of 1 inch thick wall insulation..battery powered a\c t-stat, and a computer fan to circulate cold air across frozen water bottles... I just load the bottles through a door on the outside of the box... I monitor the temps with a temp probe through the box and taped to the fermentor.. Built for no cost
