-18C to -22C Frozen Cold Storage
-18C to -22C cold storage is built for frozen food holding after products have already been frozen. The main goal is dependable low-temperature storage with stable operation during loading, dispatch and long-term stock rotation.
Frozen storage that protects finished goods
A frozen storage room is different from a blast freezer. It is not intended to freeze warm product quickly; it is used to keep frozen meat, seafood, poultry, ice cream ingredients, prepared food or packaged goods at a controlled storage temperature. The correct design reduces temperature fluctuation, helps manage defrost cycles and keeps the room practical for workers and forklifts.
Stable storage after freezing
Refrigeration capacity is selected for holding load, door traffic, lighting, people, fans and daily product movement.
Panel thickness matched to site conditions
Freezer rooms normally need stronger insulation than chilled rooms to reduce heat gain and compressor running time.
Less ice build-up on evaporators
Defrost method and schedule are chosen according to room temperature, moisture load and operating hours.
Designed for pallets, cartons or racks
Aisle width, door position and air cooler placement are coordinated so stock can move without blocking cold-air return.

Design decisions for freezer rooms
| Decision | Why it changes the configuration |
|---|---|
| Storage density | Pallet height, rack spacing and carton size affect usable capacity and airflow resistance. |
| Door traffic | Frequent dispatch needs door protection, recovery capacity and a clear unloading buffer. |
| Product temperature | Frozen goods entering at -18C require less pull-down load than warmer products entering from processing. |
| Ambient condition | Hot climates require careful condenser selection and better control of heat gain around the room. |
Before sizing the system
- Required room temperature and expected operating hours per day
- Product type, package size, pallet height and storage period
- Daily incoming and outgoing quantity, including peak season load
- Forklift or manual handling method and door opening schedule
- Preference for air-cooled, water-cooled or evaporative-cooled condenser
Planning a frozen storage room?
Share the storage volume, product type and daily turnover. AIM Refrigeration can calculate the freezer room load and recommend a practical equipment set.
