A refrigerated distribution warehouse is a collection of walk-in cold rooms, receiving docks, and preparation areas to form satellite facilities to cater for downstream activities. Being a large energy consumer, energy efficiency and temperature consistency determines the bottom line of a business.

Walk-in cold room ranges from 5 SQM to as large as a football field. It plays an integral part in post-harvesting, vaccine storage, and commercial storage that works around the clock. Investment in a cold room is perhaps the most critical decision in a cold chain business set-up.
