Humidity Control in Crop Storage and Cooling

Q: Are Condair systems energy-efficient?

Yes. Condair products use minimal energy while maintaining ideal humidity for food storage facilities.

Q: Can humidification be used during chill-down?

Yes. Humidity is added in short cycles between cooling periods to let crops reabsorb water safely.

Q: Can they be used in large crop facilities?

Absolutely. Condair offers scalable systems for small cold rooms to large industrial storage halls.

Q: How does humidification reduce weight loss?

By adding humidity, Condair systems stop crops from losing water, preserving weight and freshness.

Q: What happens if air is too dry in storage?

Dry air pulls moisture from produce, causing shrinkage, texture damage and reduced market value.

Q: Why is humidity control vital in crop storage?

Crops lose moisture quickly after harvest. Controlling humidity prevents drying, shrinkage and quality loss during cooling and storage.

Energy-efficient humidity control

During post-harvest field heat/cooling processing — sorting, grading, packing or temporary storage — crops are particularly vulnerable to moisture loss. Exposure to dry air can reduce freshness even before the produce reaches storage. Condair systems maintain controlled humidity levels in handling areas, keeping crops hydrated and in perfect condition throughout processing. A stable microclimate ensures smoother operations, higher throughput and better quality retention across every stage of post-harvest management. This is essential for producers aiming to deliver premium-grade crops consistently and reduce rejections due to quality deviations caused by environmental factors.

Extend shelf life and reduce waste

By stabilising the storage climate, Condair systems extend the storage duration of fresh produce and reduce overall food waste. Many agricultural products — such as root vegetables, apples or leafy greens — rely on a narrow humidity window to stay fresh and edible. Too dry, and crops lose water content; too wet, and spoilage begins. Condair humidifiers keep the relative humidity constant within optimal limits, reducing spoilage and extending the storage period without compromising quality. This not only supports more flexible logistics and distribution but also helps reduce losses in the food supply chain, contributing to more sustainable agricultural operations.

Use cases

Prevent evaporative losses

Organic materials have an internal moisture content and will lose moisture to the atmosphere when exposed to air with a low humidity. Humidifiers are used to create an environment with perfect balance between the material’s internal moisture content and the air’s relative humidity.

Extend produce shelf life

Extend produce shelf life with precise humidity control. Reduce spoilage, maintain freshness, and ensure optimal storage through advanced moisture management with professional humidifiers or dehumidifiers/dryers.
