As a new service to our customers, JOA would like to present our ‘Extraction System Balancing’ with the application of our proprietary software program, GCM™.
This software operates on an iterative basis resulting in precision system balancing with optimal hood flows and transport velocities throughout the system by which to guarantee long-term system performance and stability for a wide range of industrial applications. We believe that this new service may improve the overall ease of installation, reduce the cost of system balancing, and provide long-term system stability for dust and fume collection systems, regardless of who designs or installs the system.
Based upon your preferred selection for ductwork type (clamp, bolted flange, imperial, metric, etc.), the program will run through your duct network and resize each duct to the appropriate diameter. The GCM™ prepares the exact specifications for the Balancing Restrictor™ (a fixed orifice within the duct which JOA provides for precision balance). These Balancing Restrictors™ would replace the need for any adjustable dampers in your system and would provide for a stable, guaranteed system balance.
As a final deliverable, JOA will provide the overall system static pressure loss for specifying equipment such as air pollution control and fan. This is very important as the equipment must be properly specified to handle all possible design conditions to avoid any performance or safety issues.
Customers then provide JOA with the air flow requirements of their capture hoods (CFM). They would advise JOA of their minimum/maximum transport velocity requirements (FPM). If possible, we would like to have some basic project information to insure that we are designing according to best practices for your specific application, for example type of dust being conveyed, dust characteristics (particle size, bulk density, loading, etc.), dust explosivity, dust loading, and emperature of exhaust air.
As a final step, we would enter this information into the GCM™, hood by hood, duct by duct, line by line. Once the initial system data is input, the model can be readily adjusted before the final modeling is executed and final balancing output data is confirmed and provided to the client.
Also this model can be ‘archived’ within JOA database such that the customer will have ‘a living model’ of the system for future changes, expansion, retrofits or re-tasking, etc.
