IV System Design Courses

Industrial Ventilation System Design Courses

The Design course offers three levels: Phase I, Phase II and Non-Standard Air Applications.  You will be asked to select a level during your initial Conference registration.

Participants will receive a copy of the ACGIH® publication, Industrial Ventilation: A Manual of Recommended Practice for Design, 28th edition.  The design courses offer more than 20 hours of classroom instruction addressing the application of industrial ventilation system design principles. 

PHASE I • Introductory Ventilation System Design This class is intended for participants who have responsibilities for ventilation system maintenance or oversight of ventilation system projects. Participants who have had limited prior experience or specific education in ventilation system design or who do not design ventilation systems regularly are also recommended to attend this class.

PHASE II • Advanced Ventilation System Design Participants selecting this class should be thoroughly familiar with exhaust system design procedures or have satisfactorily completed a Phase I Ventilation System Design class at a prior conference. While not required, all Phase II registrants are encouraged to bring a computer.

Non-Standard Air Applications • This class will deal with exhaust systems that involve elevated air temperatures and/or moisture where air density may vary significantly from standard conditions.

The following seminars, some of which are concurrent, are offered to design course participants, specific to their chosen level:

Principles of Air Movement • Principles of Hood Design • Principles of Duct Design and Construction • Industrial Ventilation System Installation Costs • Fan Selection • Fan System Effects • Fan Installation, Operation and Maintenance • Workplace Exposure Assessments • Mechanical Collection and Baghouses • Recirculation of Exhaust Air • Applied Industrial Ventilation • Scrubbers, ESPs and Other Cleaners • Stack Design • Ventilating Combustible Dusts • Ventilation System Testing Lab

Managing IV Systems

Managing Industrial Ventilation Systems

This course has been designed for participants that have management oversight of existing industrial ventilation systems. It has been designed to follow along with ACGIH’s, Industrial Ventilation: A Manual of Recommended Practice for Operations and Maintenance (which will be provided to course participants).  The course contains a combination of classroom lectures and associated hands-on lab exercises.

Topics to be covered in this course include: • Hood flow principles and measurement • Measuring duct static and velocity pressures (SP and VP) and determining volumetric flow rate (Q) • Measuring fan static pressure(SP), velocity pressure (VP), volumetric flow rate (Q), speed (RPM) and amperage • Building fan curves • Changing the system volumetric flow rate by changing fan speed • Adding a hood to an existing ventilation system • Monitoring system performance with pressure measurements • Balancing systems by adjusting dampers • Gathering baseline data about an existing system • Proof of performance system testing • Using deviations in baseline data to diagnose problems • Troubleshooting and analysis of underperforming ventilation systems

Attendance in this course is limited to a maximum of 20 participants, so register now!  

IV for Non-Engineers

Industrial Ventilation for Non-Engineers

This course is recommended for attendees who have not completed a degree in engineering or who are unfamiliar with basic math/algebra principles, such as: industrial hygienists, facility staff, maintenance personnel, etc. Basic industrial ventilation design and operating principles will be taught in seminars. Then, rather than solve various design-based industrial ventilation problems in a classroom, attendees will participate in a variety of labs and demonstrations that exhibit principles presented in the seminars. This course of instruction provides approximately 60% seminar-based and 40% lab/demo-based learning opportunities and attendance is limited to the first 20 attendees that register for the 2023 conference.

Optional Workshops

Optional Workshops

Three optional workshops will be offered on Friday from 8 AM to 3 PM. Participants need not attend a four-day class to attend either of the workshops. Participants of the four-day Managing Industrial Ventilation Systems course should not register for the Industrial Ventilation System Troubleshooting workshop. The workshops are:

Industrial Ventilation System Troubleshooting
This workshop is devoted to procedures for troubleshooting common system problems by using the static pressure method. Topics addressed include • System Maintenance and Scheduling, Technical Documentation and Base-line at System Start-up • System Static Pressure Method for Troubleshooting • Troubleshooting Applications • Baghouse and Fan Troubleshooting

Combustible Dusts
This subject remains a hot topic as industry works to protect its employees from the potential for catastrophic deflagrations and explosions and federal OSHA works to implement a combustible dust standard. Taught by experts in combustible dust applications, this workshop is designed to address the following topics: • What OSHA Looks for on Combustible Dust Inspections • Risk Assessments and Process Hazard Analysis • Dust Collector Requirements • Explosion Prevention and Protection Systems

Computational Fluid Dynamics (CFD) Workshop

  • Practical demonstration and workshop on the use of CFD in industrial ventilation system design.
  • Workshop instruction offers how to interpret the results of a CFD analysis along with understanding how to use subsequent metrics to identify and improve the functionality of ventilation systems.
  • This workshop requires participants to bring a laptop for downloading software to be made available; a guide will be sent to workshop attendees to download the software prior to the workshop date.
  • The class will work on a CFD example and provide input on instructions and decisions.
  • This workshop is LIMITED TO 10 PEOPLE.

Review Classes

Two review classes are being offered at 5:15 on Monday night — Basic Design and Math Concepts and Psychrometrics. The basic design and math concepts review will help students with the calculations relevant to industrial ventilation design. The psychrometric review discusses how to use a psychrometric chart and defines the terms used on the chart such as dry-bulb, wet-bulb and dew point temperatures, density factor, humid volume, etc.
