Home News Company News Average Outlet Concentration < 0.3 g/m³! AODE Provides Reliable Solutions for Petrochemical VOCs Condensation Recovery
AODE temperature control solution
With the in-depth advancement of the national "Dual Carbon" strategy and the strict enforcement of the Air Pollution Prevention and Control Law, the treatment of Volatile Organic Compounds (VOCs) emissions has become an imperative demand for the green transformation of the petrochemical industry. As a critical link in oil product storage and transportation, petrochemical depots are confronted with "three core concerns": environmental compliance, operational safety, and operating costs.
AODE Custom Air-cooled Explosion-proof Chiller Units are professional equipment designed for VOCs gas condensation recovery scenarios at petrochemical oil depots. Its core advantage lies in integrating high-precision temperature control, intrinsic safety explosion protection and high-efficiency energy saving into one single unit.

High-efficiency Refrigeration System, Near-zero Emission for Oil Depot Vapor Recovery
Innovative design and manufacturing processes enable the unit to operate stably and reliably over the long term, reduce the comprehensive long-term operating cost of the chiller, and maximize its economic and environmental benefits.
1.Compressor: Adopts premium imported brand compressors to guarantee long-term stable operation
2.Eco-friendly Refrigerant: R410A refrigerant selected to balance cooling efficiency and environmental compliance
3.High-efficiency Heat Exchange: Equipped with high-performance evaporators and condensers for energy conservation, cost reduction and reliable operation
Most importantly, its powerful condensation capacity brings the average outlet concentration of oil depot facilities down to below 0.3 g/m³, far lower than the national standard emission limit of 25 g/m³. It takes a leading position domestically and basically realizes "near-zero emission" for oil depot vapor recovery.

The unit adopts air-cooled heat dissipation without cooling towers. It features flexible installation and water conservation, making it especially suitable for water-shortage regions or renovation projects with limited space.
Meanwhile, the integrated design greatly shortens on-site installation cycles, reduces construction difficulty, and facilitates subsequent maintenance and overall relocation.
For equipment operation managers, daily maintenance after chiller commissioning is equally important. AODE has made comprehensive optimizations in this regard:
1.Remote Monitoring: Supports RS485 communication and data interconnection with the user’s control room DCS system, enabling remote monitoring and control. Managers can view real-time equipment operating status in the central control room.
2.Fault Self-diagnosis: Built-in fault self-diagnosis function helps users quickly locate faults and take countermeasures, cutting troubleshooting time and downtime losses.
3.Comprehensive Safety Protection: Equipped with overload protection, phase loss/reversal protection, high/low pressure protection, low liquid level protection, anti-freezing protection and more. Multiple protection mechanisms deliver safer equipment operation.
