In the modern era of sustainable construction and material science, the Accelerated Carbonation Chamber has emerged as a critical instrument for predicting the long-term durability of concrete structures. As global carbon neutrality goals intensify, the construction industry is pivoting toward "green concrete" and carbon-sequestering materials. Accelerated carbonation testing is no longer just an academic pursuit; it is a vital industrial requirement to ensure that infrastructure—from bridges to high-rise buildings—can withstand the chemical ingress of CO2 over decades.
At Huanyi Instruments, we provide sophisticated environmental simulation systems that replicate years of natural atmospheric exposure in a matter of weeks. By controlling temperature, relative humidity, and CO2 concentration with medical-grade precision, our chambers allow researchers to calculate the carbonation coefficient and predict the onset of reinforcement corrosion.
Established on March 20, 2007, Dongguan Huanyi Instruments Technology Co., Ltd. has grown into a cornerstone of the environmental testing industry. Spanning 6,022 square meters, our facility is a hub of innovation where R&D meets precision manufacturing. We don't just build chambers; we set the standards. Huanyi has actively participated in drafting national and industry standards for environmental simulation, cementing our status as an Authority (A) in the field.
Our philosophy—"customer-centric, quality-guaranteed, honesty-based, and innovation-oriented"—is the bedrock of our Reliability (R). With nearly two decades of Experience (E), we have cultivated a team that understands the nuances of material fatigue and chemical degradation.
Located in Dongguan, the "World's Factory," Huanyi leverages a robust supply chain of internationally renowned brand components, ensuring high performance at a competitive cost basis.
Our in-house digital sheet metal processing ensures structural integrity and airtightness—crucial for maintaining high CO2 concentrations without leakage.
Our equipment meets international testing standards including ASTM C1543, BS EN 12390-10, and Chinese GB/T 50082-2009, providing a universal solution for global labs.
Comprehensive monitoring from raw material sourcing to final commission. Every chamber undergoes a 72-hour stress test before shipping.
Over 20 years of experience in environmental simulation. Our team includes specialists in thermodynamics and chemical engineering.

While atmospheric CO2 is around 0.04%, accelerated tests typically use 2.0% to 20.0% CO2 concentration. Huanyi chambers allow for adjustable settings to meet specific ASTM or GB standards.
Carbonation is fastest at a relative humidity (RH) of 50% to 70%. If it's too dry, there's no water to dissolve the CO2; if too wet, the pores are blocked by water. Our chambers maintain RH within ±2% accuracy.
Yes, we offer custom internal dimensions. Our modular shelving system supports heavy concrete specimens without compromising airflow or temperature uniformity.
We use high-grade silicone seals and specialized door locking mechanisms, combined with a pressure-relief system to ensure the CO2 concentration remains stable while preventing leakage into the workspace.
Our main components are sourced from internationally renowned brands to ensure the highest reliability. Our digital sheet metal processing and automated assembly lines allow us to reduce waste and offer competitive pricing to our global partners.
