Bry-Air, the leader in dehumidification ... worldwide, is a global solution provider having over 50 years of experience in air treatment and dehumidification. It has strong presence in the Indian sub-continent and is the leading state-of-the-art manufacturer of Gas Phase Filtration (GPF) Systems in India since last 15 years and known for setting new benchmarks. The strong research & development and testing facilities located at the GPF lab in Gurgaon are testimonial to the continuous growth and success.

Based on this legacy across the globe and country and intrinsic R&D strength, BRY-Air is proud to introduce yet another revolutionizing product solution, Atmospheric Corrosivity Monitor (ACM), which will enable measure corrosion with ease and accuracy in the environment.

Why do we need to measure atmospheric corrosion and reactivity rate?

Environment with higher atmospheric and air contamination require greater attention to air quality management. The interactive result of temperature variations and humidity with the gaseous contaminants has the potential to increase the threat of air corrosion, providing greater reasons for close monitoring of the immediate environment of IT infrastructure. All companies dealing with sensitive IT infrastructure, as a core part of its operations, need to implement a comprehensive checking and monitoring mechanism for the corrosion potential of the gases inside their facility. The ISA standards define or characterize environments in terms of their overall corrosion potential.

,MJJJT Atmospheric Corrosivity Monitor (ACM) diagnoses the corrosion of these environment according to the ISA Standard 71.04-2013 outlining severity of corrosion from G1 (mild) to GX (severe) environment. Reactivity monitoring can be used to characterise the destructive potential of an environment. Measurement of thickness of corrosion film provides an excellent indication of the type(s) and level(s) of all corrosive gases present in the local environment.

Atmospheric Corrosivity Monitor Severity level ..oIIIIIIIIr--------. Copper reactivity level (in Angstrom)* Silver reactivity level (in Angstrom)*

•

'Normalized to a 30-day exposure.

Both copper and silver reactivity levels is used for environmental monitoring with the higher of the copper and silver corrosion rates determining the overall severity level.

Severity level G1 Mild - An environment sufficiently well controlled such that corrosion is not a factor in determining equipment reliability. Severity level G2 Moderate - An environment in which the effects of corrosion are measurable and may be a factor in determining equipment reliability.

Severity level G3

Harsh -An environment in which there is a high probability that corrosive attack will occur. These harsh levels should prompt further evaluation , resulting in environmental controls or specially designed and packaged equipment.

Severity level GX

Severe -An environment in which only specially designed and packaged equipment would be expected to survive.

Specifications

Sensor Type Based on the proven Quartz Crystal Micro balance (QCM) technology in which frequency output changes due to change of weight. Stable digital output not prone to drifts or errors and can be easily processed

Sensor usable range 0-4000 Angstroms (nominal range under ideal conditions)

Display Parameters • Reactivity Levels in Angstroms - As per • ISA 71.04-2013 Std. • ISA Category levels G1 ,G2,G3,GX based on film

thickness built-up.

Features

• Provides a qualitative and quantitative measure of the overall corrosion potential of an environment

• 18-36 V DC

Installation

Cumulative value -Indicates sensor life remaining.

• Temperature • Humidity • Pressure (Optional)

Outputs • Analog: 4 Nos 4-20mA outputs • Digital: Isolated RS485 MODBUS port • USB port for easy connection to any PC or Laptop

Operating Principle

The unit utilizes copper and silver coated quartz crystal microbalances and measures the weight gain as a consequence of corrosion built up on the metal surfaces. The weight gain is translated to film thickness and the corresponding corrosivity classification level.

The unit should be installed in a clean and dry environment free from excess vibration within the region to be supervised . The monitor is wall mounted and fixed with four screws, ensure that mounting height is appropriate for easy viewing and operation ofthe keyboard.
