Intelligent Controlled Atmosphere Machine
Traditional controlled atmosphere storage adopts scattered independent devices and separate control systems, resulting in high investment, complicated installation and high maintenance costs. To tackle these industry pain points, Keda Intelligent Integrated CA All-in-One Machine is tailored for small and medium-sized CA cold rooms (single room ≤700m³, total rooms ≤5), delivering reliable and cost-effective intelligent controlled atmosphere preservation solutions.
This integrated machine combines five core functions: real-time gas analysis, high-efficiency oxygen removal, automatic carbon dioxide purification, dynamic nitrogen supply and PLC intelligent control. It replaces multiple standalone devices to realize full-automatic intelligent gas regulation for cold storage. The optimized modular design simplifies pipeline arrangement, effectively reduces gas leakage and system failures, and ensures the gas environment inside cold rooms runs stably and accurately.
The integrated design delivers prominent cost benefits, cutting 40% of equipment procurement costs, 50% of installation costs and 60% of long-term maintenance costs. The machine supports direct floor placement without complex civil works, shortening the project cycle and enabling fast commercial operation of cold storage.
It greatly lowers the technical and cost barriers of professional CA preservation, allowing medium and small growers, cold storage operators and origin warehouses to access industrial-grade intelligent controlled atmosphere preservation technology and maximize economic benefits.

Core Advantages
Multi function All in one Design: Combine gas analysis, oxygen removal and CO₂ adsorption in one cabinet. Save floor space and simplify external pipeline layout, no need to purchase separate individual units.
Fully automatic Intelligent Operation: Touch screen HMI. After setting target CA parameters for specific fruits & vegetables, the unit runs automatically. Real time O₂ & CO₂ monitoring with auto on off control, minimum manual attendance required.
Optimized for Small CA Storage: Developed for medium & small controlled atmosphere cold rooms, cost effective and lower the threshold for CA renovation projects.
High precision Gas Detection: Professional gas sensors provide real time accurate readings. Ensure stable execution of crop specific CA recipes and prevent physiological damage caused by improper gas conditions.
Durable & Easy to maintain: Modular cabinet structure for convenient inspection and part replacement. Stable continuous operation for long term cold storage working condition.
Reduce Post harvest Loss: Precisely control gas atmosphere to inhibit produce respiration, extend storage life and post storage shelf life, lower storage & export losses.
Application Cases
Small-size CA storage for fruits & vegetables: Long term preservation for table grapes, apples, kiwifruit, snow peas, longan and other produce at producing areas.
Retrofit of existing cold rooms: Upgrade conventional cold storage into CA storage without complicated multi unit layout.
Pre storage for export oriented fresh produce: Slow down ripening to match long ocean shipping logistics cycles.
Cold storage in agricultural industrial parks & logistics parks: Medium small CA rooms for rotating storage of multiple fresh crop varieties.
Fruit & vegetable cooperatives and medium small processors: Simplified CA system solution for small scale preservation projects.
FAQ
Q: Can this intelligent CA machine be installed inside the cold room?
A: This unit is designed for outside installation in machine room. It connects to CA storage via pipelines, and cannot be placed inside low temperature high humidity cold room.
Q: What volume of CA storage can one CAKFD 100 unit serve?
A: It is suitable for medium and small CA rooms. The actual applicable capacity depends on crop type and room air tightness. We can provide calculation for project selection.
Q: Do I need to adjust parameters for different fruits and vegetables?
A: Yes. Each kind of produce requires its dedicated O₂ and CO₂ recipe. You can set target values directly on touch screen, and the machine will maintain target atmosphere automatically. Wrong gas parameters may cause irreversible physiological damage to commodities.
Q: Can I retrofit my existing ordinary cold storage with this machine to build CA room?
A: Yes. But the existing cold room must be upgraded for good air tightness first. CA function can be realized after air tightness meets standard and matched with this integrated machine.
Q: Does the machine require 24 hour on site attendance?
A: It runs fully automatically after parameter setup, constant manual attendance is not required. Regular inspection and sensor calibration are recommended.
