- How tes Works?
- tes uses directed air flow and contained heat to energize water
molecules.
- Directed air flow and contained heat are keys to the Reets Evaporation
Method.
- Heat the wet materials – not the air.
- tes dries structures faster!
|
|
19
|
- According to the IICRC there are four basic principles or steps to be
followed when drying a building.
- Extraction
- Evaporation
- Dehumidification
- Temperature control
|
|
20
|
- We have great extraction tools.
- Up to 97% of the water can be
extracted from carpet and pad!*
- *SCRT W.E.T. Study
|
|
21
|
- Extraction is 1200 times faster than evaporation.
- Your efficiency just decreased by 99.91%.
|
|
22
|
- Evaporation is the bottleneck of drying!
|

|
- The higher the temperature of the liquid water, the more energetic the
molecules will be. The more energetic the molecules the more readily
they break free and leave the wet surface (evaporate).
|
|
27
|
- To increase the evaporation rate we need to increase the temperature of
the water not the air!
|
|
28
|
- Molecules moving in the air or leaving a wet surface create a pressure
on everything they touch.
- This pressure is called VAPOR PRESSURE.
- Faster moving (hotter) molecules produce greater pressure.
- Molecules packed closely together (such as on the surface of a liquid)
produce greater pressure than molecules that are widely spread out
(vapor).
|
|
29
|
- The greater the pressure difference between the surface and the air the
faster the water on the surface wants to move to the lower pressure in
the air.
- Heating the surface without heating the air makes the greatest pressure
difference!
- The difference is evaporation potential!
|
|

|
- VS -VA=E
- E=Evaporation Potential
- VS=Vapor Pressure of the Wet Surface
- VA=Vapor Pressure of the Air above the Wet Surface
|
|
31
|
- VS-VA=E
- Surface 72O/100% Air
is 76OF/90%
- 2.68-2.76= -.08
- Evaporation potential= -.08
- Surface 70O/100% Air is
78O/60%
- 2.50-1.96= 0.54
- Evaporation potential= 0.54
|
|
32
|
- VS-VA=E
- Evaporation potential remains = -.08
- Surface 120O/100% Air is
95O/30%
- 11.67-1.69= 9.98
- Evaporation potential = 9.98
|
|

|
- Moves the very wet air near the surface (the boundary layer) away.
- Speeds the transfer of heat energy.
Like using a blow dryer or a convection oven.
- Moving air reduces pressures and ‘lifts’ water molecules into the
air. Lift from moving
air is how an airplane flies.
|
|
35
|
|
|
36
|
|
|
37
|
- Lower humidity means there is less water vapor in the air. With fewer
molecules of water in the air, vapor pressure will be lower.
- A greater difference in vapor pressure between the surface and the air
will speed up evaporation.
|
|
38
|
- To maintain the greatest evaporation potential, we must either exhaust
hot humid air to the outside (replacing it with drier outside air) or
dry the air with dehumidifiers.

|
- Extraction (Same)
- Energy applied directly to the water (Temperature)
- Airflow applied directly to the water (Evaporation)
- Reduction of vapor saturation levels (humidity) by dehumidification or
evacuation (Dehumidification)

- There are certain essentials necessary for molds to grow.
- 1. Suitable temperature.
- 2. Availability of water.
- 3. Organic substrate for energy.
- 4. Presence of oxygen for respiration.
- Mold growth will slow down above and below their temperature range and
eventually growth will cease for most fungi at or above 95F.
