  8. Structural Drying Procedures by tes

  9. EXTRACTION

  10. tes in place outside wet basement

  11. tes trailer set-up to dry home

  12. Direct application of the heated airflow to the water! Floating carpet to dry the subfloor, walls and the carpet.

  13. Direct application of the heated airflow to the water! Tenting this wood floor keeps the heat where it is needed.

  14. Direct application of the heated airflow to the water! This method can be used to dry wet walls when there is a vapor barrier such vinyl wall covering.

  15. Dehumidification / Evacuation Tes hoses entering basement Thermostatically controlled exhaust

  16. 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! High Speed Structural Drying System

  17. Basic Principles of Drying • According to the IICRC there are four basic principles or steps to be followed when drying a building. • Extraction • Evaporation • Dehumidification • Temperature control

  18. Extraction We have great extraction tools. Up to 97% of the water can be extracted from carpet and pad!* *SCRT W.E.T. Study

  19. Extraction vs. Evaporation • Extraction is 1200 times faster than evaporation. • Your efficiency just decreased by 99.91%. Drying progress is now measured in gallons, not grains.

  20. Evaporation(Liquid changing to vapor) Evaporation is the bottleneck of drying! How can we speed up evaporation?

  21. UNDERSTANDING EVAPORATIONWhat are the phases of water? Solid Phase As a solid, ice, water molecules are locked into a hexagonal arrangement.

  22. As a liquid the molecules are moving faster and can break free from the crystal structure but not from each other What are the phases of water? Liquid Phase

  23. As a vapor the molecules are moving fast enough, or are hot enough, to move freely. What are the phases of water? Vapor Phase

  24. To change from liquid to a vapor the water molecules must gain sufficient energy in the form of heat to break free from each other. • 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). The key is the temperature of the water molecules!

  25. Temperature To increase the evaporation rate we need to increase the temperature of the water not the air!

  26. Understanding Vapor Pressure • 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).

  27. Understanding Vapor Pressure • 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!

  28. Formula for 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 The higher “E” the faster the evaporation rate!

  29. Example Using Fans & Dehu 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 Initial Conditions Conditions after using fans and dehumidifier for 6 hours

  30. Example Using Tes VS-VA=E Evaporation potential remains = -.08 Surface 120O/100% Air is 95O/30% 11.67-1.69=9.98 Evaporation potential = 9.98 Same Initial Conditions as previous example Conditions after Tes has been operating 6 hours

  32. Air Flow What role does air flow do in the evaporation process? • 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.

  33. Humidity What role does lower humidity play in the evaporation process? • 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.

  34. Humidity 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.

  35. Vapor Exhaust Calculator

  36. RECAP:Reets Evaporation Method • 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)

  39. Let’s talk results!Case Study #1 • Water heater in attic failed. • 300 sq ft of floor space wet • Water went straight down into 2nd floor bedroom then down into 1st floor master bedroom. • Ceiling wet • Portion of interior wall wet floor to ceiling; Other walls wet 3” to 5” up from floor. • Average grade nylon Saxony, 6lb pad..

  40. Let’s talk results!Case Study #1

  41. Let’s talk results!Case Study #1 • 2 TEX exchangers used; One in each room • Carpet, pad and concrete dry • Plywood subfloor averaged 15% MC • Walls ranged from 8-10 MC 19 hours later!

  42. Let’s talk results!Case Study #2 • Water pressure split a pipe flooding the finished basement. 1,100 Sq. Ft. soaked • Carpeted bedrooms, family room and a hallway were flooded • Ceramic tile bathroom and a concrete storage area also wet • Sheet rock walls wet. • Set-up tes with 3 tex thermal exchangers • Used air mover with thermostatic control for exhaust

  43. Let’s talk results!Case Study #2 Tes hoses entering basement Thermostatically controlled exhaust

  45. Let’s talk results!Case Study #2 • Extracted using Hydro-X with VacPac • tes was activated at 6:30 PM • Technician returned at 10 AM the next day • Carpet, pad, floors and walls were thoroughly dry Verified dry in 15 ½ hours
