Our CDI Educational Institute offers a series of Psychrometrics and Desiccant webinars plus a smorgasbord of food-related webinars as well as a webinar on Surgical Suites. 

Presented by Dr. Dry (A.K.A. Tom Peterson, CEO/Founder of Climate by Design International), they are full of facts, formulas, examples, data and graphics. We use dry wit where possible, because after all, we are the dry guys! 

Psychrometrics: The Science of Moisture in Air

Psychrometrics: The Science of Moisture in Air

Get refreshed on Psychrometrics, like a tall cold drink of water. This webinar is for those that have had formal training in Psychrometrics, at some time in their careers, but it's time to cut through the fog and get the basics of how it is used in the determination of moisture solutions.  This is a pre-requisite for all future webinars. Without an understanding of vapor pressure, dewpoint, and grains of moisture, future webinars will be cloudy at best.

Psychrometrics: The Science of Moisture in Air

Psychrometrics 201: The Science of Moisture in Air

It's time to take psychrometrics to a whole new level and jump into the proverbial deep end of the pool. This webinar is for those who have been through our basic Psychrometrics course and are now ready to apply what you have learned about vapor pressure, dew point, and grains of moisture by taking a deeper dive into a 45 Degree or Cooler Processing Room and a Hospital Surgical Suite.

Principles of Active Desiccant Operation

Principles of Active Desiccant Operation

You may already be using active desiccants, but how do they really work?  Industry "rules of thumb" may be coursing through your veins, but what are they based on?  Learn how active desiccants adsorb and desorb moisture, factors that affect performance, and industry leading energy saving possibilities.

Moisture Load Calculations

Most Load Calculation software the industry uses today does not adequately address the latent or moisture component. Don’t let yourself get into water over your head. In this webinar we break down EVERY aspect of moisture gain, give you the formulas, and demonstrate tools to make sure you have a proper design.

Hospital Surgical Suite

Hospital Surgical Suites

Operating Rooms are getting colder and colder, moisture is showing up in the worst place. Active Desiccant solution can reduce first costs, operating cost, AND keep the room dry. In this webinar we will discuss:

  • Space Design Conditions for this application
  • Load Calculation Considerations
  • Energy Comparisons
  • The Solution
  • Benefits for the O.R. as recommended by ASHE

Eliminating Condensation in a 45 Degree Environment

Are you all wet? Eliminating Condensation in a 45° or Colder Environment 

Do you desire to eliminate condensation issues that cause problems with the USDA? Do you want to reduce your sanitation dry down to less than one hour? In this session we thoroughly digest the typical 45 degree processing room, looking both at Ammonia Cooling and Active Desiccants for those critical applications. During this webinar, you will learn:

  • How a CDI Desiccant/Ammonia Rooftop (FDH) unit works
  • The Application
  • Load Calculation Considerations
  • The Solution
  • FDH Details – form fit, function and versatility

Critical Process Rooftop Food Processing Applications

Looking for another viable option to keep the air that circulates through your production areas clean, dry, and properly conditioned? Born from a King, CDI’s Critical Process Rooftop series is sized and configured so you stay in control. Any room or ambient conditions can be addressed by the CPRT’s versatility, while having the capability for full wash-down.

Spiral Freezers & Cold Storage Loading Docks

Does frost and ice have your costs spiraling out of control? Is your production cut by defrost cycles? Learn how desiccants can be applied to reduce your costs, improve product quality and increase production. This applies to spiral and tunnel freezers. It’s time you start enjoying the benefits of dry air. In this webinar we will:

  • Get to the root cause of the symptoms in your cold storage facility.
  • Understand the solutions and benefits provided by CDI desiccant technology.
  • Review the challenges of spiral freezers.
  • See how applying a cost effective Dry Climate system can make all the difference you need.

Hospital Surgical Suite

Waste Water Treatment Plants

Many Water Treatment Plants, pumping stations, or similar applications can benefit from using Active Desiccant Dehumidification.

  • Prevent the high costs of corrosion
  • Reduce operational expense

Upon successful completion of each live webinar, a certificate of attendance for 1 hour will be awarded upon request.

It is up to each individual to verify whether the course is approved by their state licensing board.
