Salt Spray Test Chamber

Salt Spray Test Chamber Solutions for Laboratories and Production

Our chambers deliver reliable, repeatable saline fog exposure for metals, coatings, fasteners, and surface treatments. Built in Dongguan, China with in‑house CNC machining and ISO 9001 controls, they provide stable conditions for NSS, AASS, and CASS. Compliance with ASTM B117, ISO 9227, JIS Z 2371, and GB/T 10125 is supported with calibration before shipment and clear documentation.

Why Choose These Chambers

• Proven engineering: 17+ years of experience, 20+ utility model patents, and contributions to national standards. Each unit ships calibrated with validation records and user training.


• Stable fog and uniform corrosion: A non‑crystallizing atomizer and tower spray deliver even saline fog and consistent collection rates. Independent air saturation stabilizes humidity and droplet size for reproducible results.


• Durable construction and safety: PVC/PP or PVDF bodies, titanium heaters, and 316 stainless fittings resist acetic and copper‑accelerated conditions. Over‑temperature, low water level, air pressure control, leakage protection, and lid interlocks aid safe operation.


• Global support and OEM: Custom fixtures, large sample handling, exhaust treatment options, and connectivity to lab networks. OEM branding, on‑site installation, and lifetime technical support via global partners.

Models and Configurations

• Sizes and footprints: Bench‑top 60–120 L units suit coating coupons and small components. Floor‑standing 270–1000 L cabinets handle larger parts and higher throughput. Reinforced lids and ergonomic heights simplify loading and inspection.


• Test methods:
  
  
  
  • NSS (Neutral): Typically 35 ± 2°C with 5% NaCl, pH 6.5–7.2. Designed for stable fog rate and uniform distribution.
  
  
  • AASS (Acetic): Acidified saline at pH 3.1–3.3. PVDF chambers and titanium heaters are recommended.
  
  
  • CASS (Copper‑accelerated): Copper chloride additive with controlled pH for accelerated programs. Precise fog generation supports consistent exposure.
  
  
  
  


• Materials and build: PVC/PP suits neutral tests; PVDF extends service life in AASS/CASS. Titanium or 316 stainless wetted parts minimize contamination. Transparent lids with pneumatic supports improve visibility and access.

Controls and Data

A touchscreen HMI with PID control sets temperature, test time, and spray intervals. Fog collection can be recorded per the standard. Optional USB/Ethernet enables data export and traceability within lab systems.

Utilities and Exhaust

DI water auto‑fill and solution level sensing help maintain concentration. Brine filtration reduces nozzle fouling and maintenance. Exhaust mist treatment and neutralization options support local environmental requirements while stabilizing chamber pressure.

Applications

• Coatings and platings: Assess zinc, nickel, chrome, organic coatings, and powder paints for blistering, rust, and adhesion.


• Automotive and fasteners: Qualify bolts, nuts, stampings, and assemblies to verify surface treatments and supplier performance.


• Electronics and enclosures: Check connectors, housings, and hardware for corrosion resistance, conductivity, and sealing over time.

Standards and Compliance

These units support ASTM B117, ISO 9227 (NSS/AASS/CASS), JIS Z 2371, and GB/T 10125. Guidance is available for parameter setup, fog collection checks, pH control, acceptance criteria, and documentation to maintain repeatable, traceable test histories.

Installation, Training, and Lifetime Support

We advise on power, compressed air, DI water, and exhaust routing to streamline commissioning. On‑site or remote training covers setup, fog rate adjustment, pH verification, and daily maintenance. Global deliveries, distributor service, and OEM options are available.

FAQs

Q: What is the difference between NSS, AASS, and CASS?

A: NSS uses neutral 5% NaCl; AASS acidifies the solution; CASS adds copper salts to accelerate corrosion. PVDF and titanium components are recommended for AASS/CASS.

Q: How do I choose the right capacity?

A: Match the chamber volume to sample size and daily throughput. Bench‑top models fit coupons and small parts; floor‑standing models handle larger assemblies and higher counts.

Q: How can I keep a consistent fog rate?

A: Verify air saturation temperature, keep the nozzle clean, and maintain brine concentration. Collect and check fog per the applicable standard, then adjust as needed.

Q: What materials should I select for aggressive tests?

A: Use PVDF bodies and titanium or 316 stainless wetted parts for AASS/CASS to improve longevity and reduce contamination.
