Originally developed for long-distance shipping, Controlled Atmosphere (CA) technology works by modifying oxygen, CO₂, and humidity levels to slow respiration and delay ripening — helping fruits retain their firmness, flavor, and shelf life over time.
ZGROUP USA now brings this powerful postharvest tool into a plug-and-play mobile format, making it accessible for growers, exporters, retailers, and agtech innovators who want to extend quality, reduce waste, or simulate shipping conditions locally.
Whether you’re preserving blueberries for air shipment or testing a new shelf-life coating, our containerized CA solution delivers scientific precision and practical flexibility.
Fine-tuned control over O₂, CO₂, humidity, and temperature.
ZTRACK™ AI automatically adjusts based on crop and ripening stage.
Installed in 20ft or 40ft containers — easy to deploy and relocate.
Plug-and-play installation, no civil work or permits required in most cases.
Use for storage, ripening, or integrate with ZSTORE XL.
Hold crops and sell when prices peak.
Ideal for shelf-life trials, cold treatment, and product R&D.
Extend freshness for coast-to-coast or export routes.
Store during peak supply and sell when demand rises.
Complete on-site cold protocols before airfreight (e.g. blueberries)
Simulate shipping to test CA tech (e.g. Apeel Sciences, contra-muestra)
