- Typical capacity
- Throughput commonly ranges from 100 to 500 crates per hour, depending on the unit's design and conveyor speed.
- Power supply
- Units of this type typically require a 3-phase electrical supply, commonly 400V, 50Hz, with varying power consumption based on pump and heater elements.
- Water heating
- Often incorporates electric, steam, or gas heating elements to maintain wash water at required temperatures for effective sanitation.
- Wash zones
- Typically features multiple zones, including a pre-wash, main wash with detergent, and a final rinse, often with a sanitising agent.

- For this class of equipment, construction is predominantly stainless steel (e.g., 304 or 316 grade) for hygiene and corrosion resistance.
- Crate compatibility
- Designed to accommodate standard industrial crates, often with adjustable guides to suit various dimensions.
- Footprint
- The physical footprint can vary significantly, but tunnel washers typically require several metres in length, plus space for access and utilities.
