SAAF Tech Tools simplifies Gas Phase Applications

Gas Phase Environmental, Analytical, and Design Solutions

SAAF Tech Tools is a decision-sciences software program for configuring clean air products to remove airborne gaseous contaminants. This decision science software walks you through the entire process by using application-specific data and predefined applications, including industry-specific information. Our software works to identify optimal media solutions, the size or volume required, their projected efficiency on a given application, and the equipment needed—ultimately creating a rapidly customized submittal package.

SAAF Tech Tools simplifies the complexities surrounding gas-phase applications through a guided problem-solving experience. It starts with a built-in table of over 900 gas-phase contaminants, 10 different chemical medias designed to target and remove those contaminants, and over 30 possible equipment solutions per application. From there, the chemical media life, operating cost index, and other key variables can be set within a user-specified range to narrow down the results, based on which factor or factors are most important for the application being analyzed.

Using chemical media utilization algorithms, SAAF Tech Tools estimates an optimized chemical media solution for you. Based on the data entered, a quick look chemical media report is generated with your initial assessment, results, and proposed solution. In addition, a full chemical media submittal may be generated that includes spec sheets, safety data sheets, and all pertinent literature for the proposed solution.

After the media selection phase, the next step is to select the proper equipment design from a comprehensive list of possible solutions that is based on your application requirements. This program gives you the ability to sort and filter equipment options to arrive at the optimum solution. A quick look equipment report showing your assessment, results, and operating cost index is generated, as well as a full equipment submittal, including all selected chemical media details, equipment drawings, equipment IOMs, and all pertinent literature.

SAAF Remaining Life Analysis (RLA) measures chemical media properties to help facilities predict remaining life, replacement schedules, and inventory requirements.

Engineers and end users often ask, "How long will the media last?" or "How frequently should the media be changed?" The answer depends on the application and the gas concentrations in the environment. Various tools can help answer these questions, ranging from air measurements to occupant surveys. AAF International recommends Remaining Life Analysis (RLA) for standard SAAF media. RLA assists customers in estimating remaining media life, confirming media activity, optimising media selection, and controlling costs with timely media replacement.

Gas-phase filtration media include a wide range of materials. Virgin activated carbon, impregnated carbon and impregnated alumina are the most common. The life of each media depends on multiple factors, such as particle size, activity level, contaminant concentrations, operating temperature, operating RH, time of operation, minimum allowable breakthrough, type of impregnant, and percent impregnation. AAF International estimates the impact of these factors on media life by comparing used media properties to those of fresh media.

For each analysed sample, AAF International produces a Remaining Life Analysis Report. The report contains the installation and equipment information, an explanation of the results, recommendations, and a summary table. This data can be logged over time to analyse the RLA trend of a system.

The SAAFShield Technology products work together as a real-time reactivity monitoring system. The information they provide helps facilities avoid the costly consequences of electronic equipment corrosion (failures of data servers, control room equipment, or other critical microelectronics).

The SAAFShield Detecting Unit works together with either the SAAFShield Reading Unit or the SAAFShield Communications Module to display and trend corrosion data over time. The Detecting Unit is the sensing side of the technology. The Detecting Unit is non-powered, providing a low-cost option that can be easily deployed at multiple locations and read periodically with the Reading Unit. Alternatively, constant trending of corrosion rates is possible when connected with a Reading Unit or Communications Module. The Reading Unit can log data on a USB drive to be graphed through the SAAFShield website. The Communications Module transmits data to building management software through a 4-20 mA signal, allowing for facility-wide monitoring.
 

The SAAF Reactivity Monitoring Coupons (RMC’s) provide information on the average air reactivity over 30 days. The information they provide helps facilities evaluate area or room conditions in relation to air reactivity and take any needed action to protect their electronics, equipment, processes, artefacts and historic assets.

RMCs determine environment reactivity through exposure in the environment and subsequent lab analysis. This technology is used to investigate the condition of control rooms or other protected environments housing electronic equipment in industrial facilities, such as pulp and paper mills, petrochemical refineries and chemical plants. RMCs are also used to investigate the condition of facilities such as data centres, museums and archives, and microelectronic production or storage areas. Additionally, mechanical equipment such as compressors can be affected by reactive gases in the air and can be evaluated with RMCs. Various standards and classification schemes correlate corrosion film amounts to reactivity classifications. Therefore, AAF International offers RMC reports in four different formats, each reflecting a different scale for characterising the overall reactivity level.
