Dynamic Pre-Cooling (Low-Pressure / Wet-Bulb Chambers): Specialized systems for unpackaged vegetables immediately after harvest. They control humidity and create a low-pressure environment that enables rapid and uniform temperature reduction. |
Dynamic Pre-Cooling (High-Suction Capacity Chambers): Designed for precise airflow and absorption timing, ensuring even cooling throughout the product mass. |
Natural Airflow Cold Room – Mist Atmosphere: Advanced storage rooms where natural airflow combined with fine misting maintains ideal microclimate conditions for humidity-sensitive products. |

- Pre-cool rapidly using Dynamic Pre-Coolers with high suction capacity and maintain the cold chain across all logistics stages.
- Keep humidity high during harvest and handling to prevent dehydration.
- Remove ethylene through proper ventilation or with the use of ethylene absorbers.
- Install ozone generators to suppress fungal growth and ensure product hygiene.
- Use modified atmosphere bags to slow respiration and extend freshness.
- Maintain medium CO₂ levels to help preserve texture, color, and quality.
- Avoid storing with ethylene-producing products such as apples, pears, or tomatoes.
