Established on March 20, 2007, Dongguan Huanyi Instruments Technology Co., Ltd. has evolved into a premier high-tech enterprise occupying a state-of-the-art 6,022 square meter manufacturing campus. As a direct participant in drafting rigorous national standards and industry specifications for environmental simulation equipment (including standard contributions such as GB5364 and GBT50325), Huanyi stands at the apex of precision engineering.
Our core operational ethos—"customer-centric, quality-guaranteed, honesty-based, and innovation-oriented"—drives an integrated ecosystem of R&D, structural design, digital sheet metal fabrication, assembly, and certified global after-sales support. Through non-stop technological iteration, Huanyi delivers industrial-grade Vacuum Chamber Ovens engineered to solve critical thermal-vacuum drying, degassing, and curing challenges across semiconductor, aerospace, lithium battery, and advanced material sectors.
Guangdong Huance Testing Technology Co., Ltd. was established as a dedicated subsidiary laboratory (2022) to ensure independent verification, ISO 17025 compliant calibration, and empirical outgassing research for every unit manufactured.
In standard convective ovens, molecular gas movement drives heat transfer. Under deep vacuum conditions (< 10⁻² Torr / 1.33 Pa), convective heat transfer drops to near zero. Huanyi’s high-performance vacuum chamber ovens utilize direct-contact aluminum/copper heated shelves combined with multi-zone infrared radiant heating walls. This achieves optimal heat transfer rates, preventing hot spots and ensuring thermal uniformity within ±0.5°C across the working chamber.
Preventing oxidation while evaporating high-boiling-point solvents requires dynamic pressure management. Our systems feature automated proportional valves linked with digital capacitive diaphragm gauges. Users can implement multi-stage vacuum profile programs, including automated high-purity Nitrogen (N₂) or Argon (Ar) purge cycles, maintaining moisture levels below 1 PPM to eliminate moisture re-absorption and thermal degradation.
Constructed using electro-polished SUS316L stainless steel internal walls, Huanyi vacuum ovens eliminate micro-porosity trapping of volatile organic compounds (VOCs). Utilizing high-grade Viton or double-layered Fluorosilicone door gaskets, our vacuum chambers sustain helium leak rates of less than 1 × 10⁻⁹ mbar·L/s, satisfying stringent NASA ASTM E595 outgassing compliance standards.

The future of industrial thermal processing relies on continuous intelligence. Huanyi is embedding edge-computing IoT sensors and physics-informed AI models into our vacuum ovens. By simulating heat radiation and mass transfer kinetics in real time, the system automatically predicts sample drying completion, optimizes energy consumption by up to 34%, and detects vacuum seal degradation before catastrophic vacuum loss occurs.
With quantum computing modules and sub-2nm semiconductor lithography optics demanding microscopic cleanliness, standard rotary vane or dry scroll pumps are insufficient. Huanyi’s technology roadmap incorporates turbomolecular and cryo-pump integrated vacuum chambers capable of reaching 10⁻⁷ mbar, guaranteeing zero hydrocarbon backstreaming for next-generation optical and wafer processing.
As global environmental regulations (such as REACH and EPA VOC emission limits) tighten, vacuum ovens must actively trap effluent gases. Our roadmap features integrated multi-stage cryogenic solvent traps that condense up to 99.4% of volatilized solvents (such as NMP, Acetone, and Ethanol), turning waste handling into an automated, eco-friendly closed loop.
Transitioning from batch operation to fully automated continuous smart manufacturing, Huanyi's next-generation vacuum platforms interface seamlessly with SECS/GEM protocols and cleanroom ISO Class 3 automated guided vehicles (AGVs), facilitating robotic loading and unloading without breaking cleanroom laminar flow environments.
Use Cases: Wafer degassing, polyimide bake-out, epoxy die-attach curing, flip-chip underfill processing.
Solution: Class 100 cleanroom compatible vacuum ovens equipped with dual nitrogen purge valves, HEPA particle filtration, non-contact heating elements, and precise temperature ramping control preventing substrate thermal shock.
Use Cases: Cathode/anode electrode coil drying, cell electrolyte vacuum degassing, thermal runaway testing.
Solution: High-capacity industrial vacuum drying ovens with integrated explosion-proof pressure relief valves, inert gas backfilling, and precise moisture removal to strictly under 200 PPM before electrolyte injection.
Use Cases: Satellite payload outgassing, composite carbon fiber curing, thermal vacuum space environment simulation.
Solution: Deep-vacuum thermal chambers capable of simulating low Earth orbit (LEO) vacuum pressures combined with extreme thermal cycling range (-70°C to +200°C) certified to ASTM E595 testing metrics.
Located in Dongguan—the global hardware manufacturing epicenter—Dongguan Huanyi Instruments leverages a fully integrated, vertically aligned supply chain. In 2016, Huanyi established a dedicated Digital Sheet Metal Manufacturing Center equipped with automated high-power fiber laser cutters, CNC bending machines, and robotized welding stations.
By implementing a cloud-based ERP and MES production tracking platform, Huanyi streamlines raw material acquisition, sheet metal processing, leak testing, and electrical wiring assembly. This operational agility minimizes component procurement lead times, allowing us to deliver bespoke custom vacuum chamber ovens in 3 to 4 weeks, compared to the 8 to 12-week industry standard offered by overseas competitors.
All Huanyi vacuum chamber ovens strictly comply with international electrical and safety benchmarks. Certified under ISO 9001:2015, our equipment holds full CE Mark compliance (Low Voltage Directive & EMC Directive) and can be ordered with UL 508A certified industrial control panels tailored for North American enterprise deployment.
For pharmaceutical and high-reliability aerospace clients, we supply comprehensive validation packages including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocol templates, alongside Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) execution.
For operations involving volatile solvent evaporation or battery thermal runaways, Huanyi manufactures certified explosion-proof vacuum drying systems adhering to ATEX Zone 1 / Zone 2 standards, featuring intrinsically safe instrumentation, inert purging interlocks, and blast-relief doors.
With persistent dedication since 2007, Huanyi products are exported to Southeast Asia, Europe, North America, and the Middle East, serving over 2,500 enterprise customers.
