Abstract: An elevator shaft in a multi-story cold storage warehouse is modified to substantially isolate the atmosphere in the shaft from that in the warehouse and also from the ambient. Small amounts of heat are then added to the shaft and also means to cause positive circulation of the shaft atmosphere to prevent build up of frost and ice on the shaft interior, the elevator car, the cables and other parts within the shaft.
