Key Features of Salt Fog Chambers

Our salt fog chambers are engineered to provide precise and reliable testing conditions, ensuring that your materials and coatings can be evaluated under the most challenging environments. Here are some of the standout features of the chambers we distribute:

Shell Design

  • Double-Wall Construction: The chambers feature a double-wall, water-jacketed design, which ensures accurate temperature control and stability throughout the testing process. This design also enhances the durability and longevity of the chamber.
  • Corrosion-Resistant Lining: The interior of the chamber is lined with an oven-cured, continuous polymer coating, providing maximum service life and resistance to corrosive elements.

Opti-Fog™ Fog Generation System

  • Patented Design: Our chambers utilize the patented Opti-Fog™ fog generation towers with baffling, designed in accordance with ASTM B117 standards. This system ensures uniform fog distribution and consistent test results.
  • Humidifying Tower: The integrated humidifying tower saturates the incoming air supply with humidity, maintaining stable and accurate test conditions. A low water sensor system is included to protect the heater from damage.

Control System

  • Precision Controls: Each chamber is equipped with individual temperature controls for the exposure zone dry bulb, exposure zone wet bulb, and the humidifying tower. Users can easily switch between °C and °F units for convenience.
  • Air Regulation: The chambers feature a precision air regulator assembly, along with a certified 4-inch pressure gauge and an air flow meter, ensuring precise control over test conditions.

Solution Reservoirs

  • Level-Matic™ Control: The chambers include 10-gallon DI water and 24-gallon solution reservoirs, featuring the patented Level-Matic™ level control system. This system maintains consistent solution levels, reducing the need for manual adjustments.

Certification and Start-Up Kit

  • NIST Certification: The chambers are certified with calibration traceable to the National Institute of Standards and Technology (NIST), ensuring compliance with industry standards.
  • Comprehensive Start-Up Kit: Each chamber comes with a start-up kit that includes condensate collection assemblies, a 50lb bag of salt, a specific gravity hydrometer, PTFE filter cloths, support racks, support bars, and a specimen tray.

Best Practices for Salt Fog Chambers

To ensure optimal performance and accurate results from your salt fog chamber, consider the following best practices:

Proper Setup:

Ensure the chamber is installed in a well-ventilated area and that all connections (electrical, air, and water) are securely in place before starting the test.

Regular Calibration:

Regularly calibrate the chamber’s controls and sensors to maintain accuracy and compliance with testing standards. Utilize the NIST-traceable calibration certification provided with the chamber.

Maintenance:

Regularly check and clean the fog generation system, humidifying tower, and solution reservoirs to prevent buildup and ensure consistent operation.
