Advanced condensation followed by regenerative thermal oxidation (RTO) to abate toxic solvent vapor in rigorous air quality basins.
Learn MoreThe Greater Los Angeles Area—spanning Long Beach, Torrance, the San Fernando Valley, and the Inland Empire corridor—has transformed into North America's premier hub for electric mobility innovation, eVTOL development, and aerospace precision coatings.
However, scaling advanced battery cathode manufacturing and high-temperature polymer coating within the South Coast Air Quality Management District (SCAQMD) presents stringent regulatory challenges. N-Methyl-2-pyrrolidone (NMP) is cataloged as a toxic air contaminant and reproductive toxicant under California Proposition 65 and EPA TSCA regulations. Discharging NMP vapors without high-efficiency capture invites severe penalties and halts permits.
Under SCAQMD Rules 1151 and 1147, solvent recovery units must deliver rigorous emission control metrics. DryAir’s multistage custom NMP recovery platforms combine condensation heat exchange with rotating molecular sieve zeolite concentrators to reach recovery efficiencies exceeding 99%.
How Hangzhou DryAir’s world-class fabrication infrastructure drives CAPEX reduction, faster lead-times, and uncompromising build quality for American engineering teams.
With an expansive manufacturing campus in Qingshan Industrial Park and 200+ monthly unit throughput, our direct manufacturing model eliminates third-party distributor markups, cutting turnkey capital equipment costs by 30% to 45% compared to domestic US fabricators.
Engineering built for US inspection: every system configured for the North American market carries options for full UL 508A industrial control panel certification, ASME Section VIII pressure vessel stamps, and CSA ratings to ensure expedited permit approval in the City of Los Angeles.
Our technologies operate inside production facilities belonging to CATL, BYD, Tesla, and Northvolt. We leverage empirical CFD airflow modeling and verified thermodynamic condensation cycles, eliminating field-trial risks on your assembly lines.
Precision environmental controls and solvent containment engineered for mission-critical industrial sectors.
Silicon Valley and Southern California EV startups operate cleanroom coating lines requiring high-efficiency NMP stripping from wet slurry matrices without moisture contamination into downstream assembly dry rooms.
Hawthorne and Long Beach aerospace defense manufacturers utilize NMP as a solvent vehicle for aromatic polyimides and fluoropolymers. Our systems capture VOC exhaust during high-temperature autoclave and curing stages.
Microelectronic foundries in Southern California rely on ultra-pure NMP to strip photoresists. DryAir closed-loop recovery units retain chemical purity while preventing discharge into coastal municipal sewer or air sheds.
Standard operating benchmarks for DryAir industrial installations worldwide, adaptable to local Los Angeles gas, electrical, and structural codes.
