- Can be moved by truck, crane, or forklift
- Plugs into standard reefer socket or generator
What Is Modular Cold Storage?
A modular coldroom is a purpose-built, panelized cold storage system installed inside an existing building or as a standalone structure, engineered from the ground up for stationary cold storage.
Key Features
- Insulated sandwich panels (typically 75mm to 200mm thick)
- Remote refrigeration system
- Flexible sizing — not limited to standard container dimensions
- Permanent or semi-permanent installation
- Temperature range: -25°C to +15°C
