Cold-store selection must use the project's minimum temperature and door cycles rather than room-temperature data alone. Thermal cycling affects drivers, seals, cables and lenses.
Rack freezers, open rooms, blast areas, ante rooms and docks should be checked separately for optics and controls.
Check the complete system at worst temperature
Confirm starting and stable operation of fixtures, drivers, sensors and connectors at target conditions.
- Separate room and surface temperature
- Check start, not storage only
- Consider frequent switching
Control condensation paths
Warm moist air, cable entries and pressure changes can introduce water.
- Check seals and glands
- Reduce cold bridges and water traps
- Verify protection in installed orientation
Match optics to racks
High racks need vertical and aisle uniformity, while open stores need broad coverage.
- Record rack height and aisle width
- Avoid evaporator shadows
- Check loading and picking planes
Controls must also tolerate cold
Sensors, controllers and driver interfaces need low-temperature testing and suitable delay.
- Consider panel reflections
- Use aisle grouping
- Keep emergency and manual modes
