Core Technology
Bernoulli's Atomization Principle
Bernoulli’s Atomization Principle: JCT salt spary chamber utilizes Bernoulli’s principle to aggressively mix compressed air with a 5% NaCl saltwater solution.
This mixture is then atomized through specialized quartz glass nozzles to create an incredibly uniform, fine salt fog .These fogs blanket every microscopic crevice of your test specimen, accelerating the electrochemical corrosion process.
The Saturated Air Tower
The biggest pain point in salt spray testing is clogged nozzles. Our advanced air saturator tower will pre-heat and strictly humidify the compressed air before it ever reaches the quartz nozzle.
This entirely physically prevents salt crystallization, ensuring a continuous, unbroken spray for hundreds of hours.
Precision PID & Automatic Defogging
Smart PID algorithms maintain strict temperatures (35°C for NSS, 50°C for CASS) with ±0.5°C fluctuation. Before you open the lid, an automatic pneumatic defogging system rapidly clears the corrosive gases, strictly protecting your laboratory equipment and personnel.

Applications
Salt spray chamber for Hardware & Fasteners
Construction hardware, such as galvanized bolts, nickel-plated hinges, and chrome fasteners, faces constant exposure to humid, corrosive air.
By Simulating years of environmental abuse, our salt spray chambers evaluate the long-term oxidation resistance of these crucial joints. This aggressive testing forces surface platings to prove their durability, permanently eliminating the risk of structural seizing and catastrophic mechanical failures in outdoor construction projects.
Salt spray chamber for Automotive
Vehicles face harsh road de-icing salts and humid coastal climates daily.
By Using our JCT highly aggressive CASS (Copper Accelerated Acetic Acid Salt Spray) test, we evaluate chassis electrophoretic paint, exhaust coatings, and electroplated badges. This extreme validation guarantees that exterior automotive trim and undercarriages will not blister, peel, or develop creeping rust, securing your compliance with Tier-1 OEM standards
Salt spray chamber for Surface Treatment & Coatings
Industrial anti-rust paints and powder coatings must protect the underlying metallic substrate from moisture and oxygen.
Our ASTM B117 salt spray chambers continuously expose coated panels to highly corrosive environments to observe if the paint film blisters, peels, or allows creeping rust to propagate from micro-scratches. This empirical data verifies the exact lifespan of your chemical coating formulas and prevents costly post-market coating failures.
Salt spray chamber for Electronics & Telecommunications
Outdoor 5G base stations and exposed PCB ENIG (Electroless Nickel Immersion Gold) processes are highly vulnerable to coastal high-salinity air.
Salt fog aggressively attacks and oxidizes exposed metal contacts and connectors.
By processing rigorous NSS testing with JCT salt spray chamber, telecom manufacturers can prevent high-frequency signal attenuation and fatal short circuits, ensuring that critical 5G infrastructure survives decades of deployment on humid coastlines without hardware degradation.
Salt spray chamber for Marine & Offshore Engineering
The ocean is the most corrosive natural environment on Earth. Offshore wind turbine components, deck steel, and specialized marine coatings are constantly battered by high-salinity seawater and heavy mist.
Subjecting these materials to exceptionally long salt spray exposures in our large-capacity chambers validates their ultimate corrosion margins.
This strict testing is the only way to prevent catastrophic structural degradation and secure maritime engineering certifications.
Salt spray chamber for Aerospace & Aviation
Aerospace Flight equipment frequently transitions between high-altitude salty moisture and corrosive runway environments.
Critical mechanical structures, such as landing gear coatings and anodized aluminum alloys, must endure aggressive environmental attacks without compromising flight safety.
Testing strictly according to MIL-STD in our precision Corrosion Test Chamber can ensure that these aerospace-grade materials will not suffer from galvanic corrosion, pitting, or structural fatigue.

FAQ
Q1: What exactly is a salt spray test chamber?
It is an enclosed testing cabinet that continuously atomizes a high-concentration salt fog onto test specimens. It aggressively accelerates the simulation of coastal or corrosive environments to evaluate the rust resistance of metals and surface coatings.
Q2: What is the difference between NSS and CASS tests in this chamber?
NSS (Neutral Salt Spray) uses a 5% pure saltwater solution at 35°C, ideal for standard plating and paints.
CASS (Copper Accelerated Acetic Acid Salt Spray) adds copper chloride and acetic acid and operates at 50°C, causing an incredibly aggressive corrosion rate specifically designed for tough nickel-chrome plating or anodized aluminum.
Q3: How many hours in a salt spray chamber equals a year in the real world?
A common industry estimation is that 24 hours in a Neutral Salt Spray (NSS) chamber roughly approximates the corrosion equivalent of 1 year in a natural coastal environment.
Q4: With so much corrosive fog inside, will the chamber itself rust?
Absolutely not.
The entire JCT-SSC series—including the shell, internal brackets, and piping—is welded from heat-resistant, acid-proof PVC or PP plastic. There are zero exposed metal parts to rust.
Q5: What international testing standards does the chamber meet?
The equipment fully complies with all major global specifications, including ASTM B117, ISO 9227, IEC 60068-2-11, and JIS Z 2371.
Q6: What size chamber do I need for my products?
It depends entirely on your largest test specimen.
Test items must not block the spray path of other items and must maintain a specific distance from the chamber walls.
Share your maximum sample dimensions with our engineers, and we will recommend the perfect capacity from our 60L to 220L
Q7： Can I place heavy metal parts or large automotive components directly on the bottom of the chamber?
No.
Test specimens should never touch the chamber floor directly. They must be placed on the specialized V-shaped sample racks, glass rods, or hanging bars provided, this can ensure they are angled (typically 15° to 30° from vertical) so that droplets can run off freely without pooling.
Q8: How long does the chamber take to reach the stable operating temperature of +35℃ or +50℃?
The JCT-SSC chamber typically reaches and stabilizes at the required test temperature within 30 to 45 minutes from a cold start.
Q9: What power supply and electrical specifications are required for installation?
The JCT-SSC series operates on a standard industrial 380V AC, 3-Phase, 50Hz power supply. Please ensure your facility has compatible heavy-duty wiring and a dedicated circuit breaker ready
Q10: What is the standard packaging and shipping protection for international delivery?
Our standard packing is that the chamber is wrapped in protective waterproof film, secured with thick foam cushioning, and fully enclosed inside a robust, export-grade fumigated wooden crate.
