CO₂ Adsorber
The biggest challenge in fruit and vegetable cold storage is not low-temperature preservation, but the uncontrolled accumulation of carbon dioxide. Fruits and vegetables continuously release CO₂ during respiration. Excessive CO₂ easily causes browning, texture deterioration and rot, leading to huge economic losses even with precise temperature control. Equipped with a professional CO₂ Adsorber can perfectly solve this industry problem.
Keda CAD series CO₂ remover, a high-performance CO₂ Adsorber tailored for controlled atmosphere cold storage, adopts mature PSA technology. It monitors the internal gas environment 24/7 with automatic start-stop and intelligent adjustment. It stably maintains the optimal CO₂ concentration range for fruits and vegetables, fundamentally avoiding CO₂ damage and decay caused by excessive carbon dioxide accumulation in the cold storage.
Featuring unattended operation and low energy consumption, the equipment supports long-term storage of various agricultural products. It effectively extends the fresh-keeping period, locks the original taste, color and nutrition of fruits and vegetables, greatly reduces storage loss, and helps cold storage and planting bases increase profits by staggered listing.

Core Advantages
Fully automatic Intelligent Regulation: PLC automatic control, real time CO₂ data sampling. Auto start for CO₂ removal when over threshold and auto-stop after reaching set value, minimal manual intervention.
Oxygen free Regeneration Technology: No extra oxygen generated during adsorbent regeneration, will not disturb low oxygen atmosphere inside CA room and keep whole CA system stable.
Powerful CO₂ Removal Capacity: Large processing capacity, quickly bring CO₂ down to crop matched range and prevent CO₂ poisoning damage.
Flexible for Various Crop Recipes: Adjustable upper & lower CO₂ limit values for different fruits & vegetables, suitable for table grapes, kiwifruit, durian, apples and more varieties.
Energy saving & Reliable Operation: Physical adsorption principle without chemical consumables, qualified for long term non stop cold storage working condition.
Modular Cabinet for Easy Maintenance: Modular layout for convenient inspection and part replacement, reduce after sales maintenance cost.
Parallel connection Available: Multiple units can run in parallel to satisfy large volume CA storage projects.
Application Cases
Specialized CA storage for various fruits & vegetables: Long term preservation for apples, table grapes, kiwifruit, pears, durian etc., precisely control CO₂ concentration.
New built CA cold storage projects at producing areas: Work as standard supporting equipment and cooperate with deoxygenation nitrogen adsorber for complete CA system.
Retrofit projects of existing cold rooms: Solve CO₂ accumulation caused by produce respiration after cold room CA renovation.
Large scale CA storage clusters in logistics & industrial parks: Support multi unit parallel operation for multi warehouse projects.
Pre storage for export oriented fresh produce: Keep stable storage atmosphere, avoid CO₂ injury and match subsequent ocean shipping logistics.
Fruit and Vegetable Case Studies
7 month long term CA storage for Shine Muscat grapes with CO₂ Adsorber. Grapes continuously produce CO₂ via respiration. The adsorber removes excess carbon dioxide in real-time and keeps CO₂ within safe range to prevent CO₂ injury and browning. Combined with precise temperature, humidity and O₂ control, fruit respiration and senescence are suppressed. After storage, grapes maintain good firmness, stable brix and natural muscat flavor with green stems. It reduces storage loss and enables stable off-season supply of Shine Muscat grapes.
FAQ
Q: Can the CO₂ adsorber be installed inside the CA cold room?
A: It is outdoor type unit for machine room installation, connected to CA storage via pipelines. Do not place it inside low temperature high humidity cold room.
Q: Must CO₂ adsorber work together with deoxygenation nitrogen adsorber?
A: Complete CA storage system recommends both units. If you only use CO₂ adsorber, it can merely remove carbon dioxide without oxygen reduction, full CA preservation effect cannot be achieved.
Q: Is the CO₂ setting value identical for all fruits and vegetables?
A: No. Each produce has its own safe CO₂ range. Too high CO₂ setting will lead to CO₂ poisoning and irreversible physiological damage.
Q: Will poor cold room air tightness affect unit performance?
A: Yes. Air leakage causes continuous gas loss, triggers frequent start stop, fails to hold target CO₂ level and increases power consumption
Q: Does the unit require 24 hour on site attendance?
A: Fully automatic operation after threshold setting, full time attendance is unnecessary. Regular inspection and CO₂ sensor calibration are recommended.
