With the full-scale rollout of the East-to-West Computing Project, large-scale intelligent computing centers, IDC computer rooms and cloud computing bases are widely equipped with diesel generator sets as emergency backup power supplies. These units remain on standby for long periods, start and stop frequently, and operate under highly unstable alternating hot and cold conditions. Coupled with the tightening of domestic ultra-low emission regulations as well as international environmental standards including Tier 4 and Stage V, the industry is plagued by common operational headaches such as excessive nitrogen oxide emissions, urea crystallization and blockage, excessive ammonia slip, high equipment backpressure, and limited space for renovation inside computer rooms. Conventional generic SCR equipment is only designed for continuously running generator sets. When subjected to the intermittent startup cycles of backup units, they often suffer failed denitrification, frequent breakdowns and excessively high maintenance costs.
Based on the actual operating conditions of data centers, Green Valley Environmental Protection has developed a full-process integrated exhaust treatment system featuring DOC+DPF+SCR+ASC. We have carried out targeted technical upgrades to meet core requirements for backup generators, including drastic fluctuations during startup and shutdown, frequent low-temperature operation, limited on-site space in computer rooms, and long-term stable maintenance-free performance. Multiple key performance indicators outperform conventional similar products on the market, delivering a one-stop solution for environmental acceptance and long-term reliable operation for thousands of computing hubs.
The complete system is equipped with an IoT remote module. It automatically records flue gas temperature, NOₓ concentration, urea consumption and ammonia slip data. Remote access is available across multiple terminals, with pop-up alerts triggered automatically when emission limits are exceeded. It fully complies with the intelligent operation and maintenance standards of data centers and easily meets real-time online supervision from environmental authorities.
Green Valley adopts a highly integrated modular design suitable for confined rooftop spaces. Most suppliers split DOC, DPF and SCR into separate discrete units with lengthy pipelines and large floor areas, making retrofits on data center rooftops and flue ducts difficult to implement. Green Valley integrates all components into a compact skid-mounted integrated unit with a small footprint. The whole unit is fabricated with stainless steel integral welding, delivering excellent high-temperature resistance and corrosion resistance. It withstands long-term outdoor exposure on rooftops without rusting, and the catalyst boasts an extended service life. This drastically cuts consumable replacement expenses and lowers the total cost of ownership throughout the equipment lifecycle.
Our integrated solution simultaneously eliminates black smoke particulate matter, carbon monoxide and nitrogen oxides, achieving Ringelmann Class I zero visible smoke. The system can be configured with UL and Tier 4 certifications, and we offer customized manufacturing for overseas data center projects across Southeast Asia, Russia, Europe and North America.
