This is Coca-Cola’s largest inventory for concentrate to support all the bottling factories across Asia Pacific. Considering the massive storage capacity, Coca-Cola employed a half auto high bay store for convenient logistics handling.
We were given a number of parameters and constraints to begin with – frequent door opening for the walk-in up to 600 times a day; condensation water that would freeze up over a long travel inside a freezer; how to access a high-level evaporator at 18m for maintenance; cold room door of 6.3m high, etc.
We introduced the ‘air door’ technology simply by adding in a dual wind curtain to stop air going in/out through the cold room. The condensation water was let out directly at a high level on a gradient to the rooftop, thus skipping the long travel inside the freezer. Evaporators above were surrounded with catwalks and enclosed by a plant room on top for easy maintenance access. Lateral injection technique against non-uniform foaming and guide rail mounted on top and bottom of the door were used for spreading the heavy weight of the door. Hot air was used to defrost for energy-saving reasons.
