How are you different than other trainings?

a. We help you make sense out of your psychrometric logs.
b. Educate you on knowing if your drying strategies are working or not each day of the loss.
c. Grow your confidence in your job and know when and what changes need to be made to your drying strategy.
d. Determine which drying equipment technologies will work best in all conditions.
e. We teach you how to calculate and determine which conditions will dry the fastest and how much faster.
f. Learn to predict drying times.

General Information

What is E³, and why is it essential in water damage restoration?

E³, or Enthalpy Evaporation Evaluation, is a unique metric designed specifically for the water damage restoration industry. It evaluates the evaporation or drying power of air based on temperature, vapor pressure, dew point, and other psychrometric factors. This system provides scientific and mathematical justification for drying setups, ensuring that restorers can make evidence-based decisions to optimize drying times and effectiveness.

What does an E³ Value represent, and how is it calculated?

What is E³ Targets, and how should they be interpreted?

E³ Targets are daily benchmarks for assessing the efficiency of the drying setup. These targets are calculated based on factors such as equipment type, loss class, day of loss, elevation, and external environmental conditions. If targets are met each day, it indicates that the setup is effective. Failure to meet targets may signal inefficiencies or the need to adjust the drying setup.

What’s the difference between Open and Closed System Controls, and when should each be used?

Open System Controls: These are used when exchanging air between the drying chamber and the outside environment, typically when heating or temperature control is necessary. Open systems can help restorers manage desired temperature, airflow, and BTU/hr needs based on chamber volume and outside conditions.
Closed System Controls: Used when air is recirculated within the chamber without introducing outside air. This system is ideal when trying to maintain specific temperature conditions based on heat loads from drying equipment alone.

Equipment and Calculations

How do I determine the right number and type of air movers for a project?

What factors influence the selection of dehumidifiers?

How do I calculate the BTU/hr for heating or dehumidification equipment?

What is a grain depression, and how does it relate to dehumidifier performance?

What are Air Scrubbers, and how do I select the right model?

Specialized Drying Scenarios

How does the app determine the cooling capacity of an HVAC system in a drying chamber?

What’s the purpose of a floor drying system, and how is it set up?

Floor drying systems are used to efficiently dry specific flooring types, such as
sanded and finished hardwood or ceramic tile on subfloors. The app allows you to select
the type of flooring and wet area size to determine the necessary drying units and setup.
For instance, if drying sanded hardwood, the app might suggest a system with high-
precision mats that target water extraction from the floor’s surface.

Job Workflow and Documentation
