- Typical footprint
- Chiller rooms of this class commonly range from 2m x 2m up to 6m x 6m or larger, depending on modularity.
- Operating temperature range
- Typically maintains temperatures between 0°C and +8°C, suitable for chilled storage.
- Insulation material
- Panels are commonly constructed from insulated sandwich panels, often polyurethane (PUR) or polyisocyanurate (PIR) foam, clad in steel.
- Power supply
- Refrigeration systems for units of this size typically require a 230V single-phase or 400V three-phase electrical supply, depending on compressor capacity.
- Refrigerant type
- Modern systems commonly use HFC refrigerants such as R404A or R449A, or increasingly natural refrigerants like R290 (propane) for smaller units.
- Door type
- Units typically feature hinged or sliding insulated doors, often with an internal safety release mechanism.
- Assembly
- Designed for modular assembly, with cam-lock or tongue-and-groove panel joining systems for ease of installation and dismantling.
