Engineered for freezer maintenance, the JBT FoodTech Clean Safe customized internal decking system cleans any low-tension spiral freezer. With the deck structure installed within the freezer’s cage, the system provides a water input at the base of the spiral and hose connections on every deck layer. An anti-entry locking system allows access only when the spiral is not operating. Full-length ladders provide access from the bottom to the top deck. The system includes hand-operated ball valves at each deck level to connect a spray wand.
