Why Choose Controlled Atmosphere Cold Storage?
- Standard cold storage only controls temperature. controlled atmosphere(CA) storage also manages O₂ and CO₂, slowing respiration and delaying ripening.
- Adds humidity and atmosphere control on top of temperature, keeping storage conditions more stable.
- Less moisture loss, less spoilage, less quality decline—so less waste over long-term storage.
- Keeps color and flavor intact, preserves market value, and makes off-peak sales possible.
- Built for produce that needs longer, more demanding storage—apples, kiwifruit, blueberries, and more.
Your Trusted Controlled Atmosphere Cold Storage Engineering Partner in China
“When building a Controlled Atmosphere cold storage facility, equipment alone won’t cut it—the design has to fit your produce and how you operate. HeShun designs systems around your produce types, storage duration, and workflow.
One team handles everything: airtight sealing, system configuration, installation, and commissioning. No juggling multiple suppliers. With precise gas control and standardized construction, we cut storage losses and keep produce fresher.

Core Systems of Controlled Atmosphere Cold Storage
CA cold storage is about more than just cooling—the gas environment inside matters just as much. Airtight construction, gas regulation, humidity control, and smart management all have to work together for produce to store well.
Airtightness is what makes a CA facility work. Panel joints and doorways get a proper seal to keep outside air out, so the gas environment inside stays stable. Airtightness is tested once construction is done to make sure it meets operating standards.
Produce gives off CO₂ during storage, and too much of it hurts storage quality. The CO₂ removal system tunes itself to internal conditions, keeping gas levels where they should be.
Ethylene pushes produce to ripen and age faster. Lowering ethylene levels inside slows down quality decline—especially helpful for demanding crops like blueberries and kiwifruit.
O₂ and CO₂ need constant monitoring to keep the CA environment stable. The system reads the data in real time and adjusts equipment to preset parameters, so there’s less manual work.
Produce quality drops when moisture is lost during storage. The humidification system works alongside the refrigeration system to keep humidity right and cut weight loss from dehydration.
Temperature, humidity, O₂, and CO₂ are all managed in one place, with remote monitoring available. Operating parameters can be set for different produce varieties, cutting down on day-to-day work.
More About Our Controlled Atmosphere Cold Storage
- Controlled Atmosphere Cold Storage vs Standard Cold Storage
Controlled-atmosphere cold storage does more than chill your produce. It manages O₂, CO₂, and humidity too, so fruits like apples and blueberries last longer and you’re not forced to sell in a hurry.
| Comparison Item | Standard Cold Storage | Controlled Atmosphere Cold Storage |
| Storage Principle | Lowers temperature to slow spoilage | Low temperature plus atmosphere control, slowing respiration further |
| Temperature Management | Controls temperature only | Precise temperature control, coordinated with atmosphere management |
| Humidity Control | Adjusted to the produce | Carefully managed to cut moisture loss and wilting |
| O₂ Concentration Management | Natural air; not adjusted | O₂ levels set to the produce to delay ripening |
| CO₂ Concentration Management | No active regulation | CO₂ monitored and controlled automatically |
| Ethylene Control | No specific treatment | Optional ethylene removal to reduce ripening effects |
| Suitable Products | Everyday fruits and vegetables, for short-term storage and fast turnover | High-value produce: apples, pears, kiwifruit |
| Storage Duration | Weeks to months | Extended, with room for staggered sales |
| Operational Management | Mainly temperature-focused | Temperature, humidity, O₂, and CO₂ managed together |
Yes. No two projects are the same here—apples and blueberries don’t even store the same way. So we sit down, look at what you’re storing, how much, and how you run the place, then build the controlled-atmosphere cold storage system around that. Structure, refrigeration, gas control, monitoring—all matched to your setup. It’s your facility; it should fit you.
Honestly, it depends. The size, how much you want to store, the design, the site itself—all of it matters. But here’s the deal: before we start, we lay out a construction plan with you, so you know exactly what’s happening and when. Then we keep everything on track—that’s how your controlled atmosphere cold storage gets up and running on schedule.
We’ve got you covered. We handle overseas controlled atmosphere cold storage projects all the time. Our engineering team can come to your site for installation, commissioning, and hands-on guidance. And we stick around—from planning and construction all the way through to after-installation support. If we can’t get someone on-site easily, we’ll walk you through it remotely instead. Either way, we don’t leave until your controlled atmosphere cold storage is running right.
Once a year is what we’d recommend. That keeps the atmosphere doing its job. You can also keep an eye on it between checks—when O₂ and CO₂ levels start drifting, something’s leaking. And when you do check, pay attention to the usual suspects: door seals and pipe connections. Airtightness is what makes controlled atmosphere cold storage work, so it’s worth staying on top of.
