2. The Drying Process Nigel Hewitt Technical Manager

3. Traditional Methods Evaporation Air movement –Air movers –Injection Drying Systems –Tenting

4. Traditional Methods Dehumidifiers –Domestic Refrigerant –Commercial Refrigerant –Low Grain Refrigerant –Desiccants

5. What Effects The Drying TEMP AIRFLOW Humidity

6. Surface Free Water Bound Water Temperature Humidity Airflow

7. The Way Forward ? Traditional –Dehumidification New Technologies –Heat –Speed –Size –Cost

8. Heat Drying Systems Convection Drying Systems –Open type Heats Air Built in moisture evacuation –Hydronic Heats Liquid Glycol Problems evacuating moisture

9. How They Work Vapour Pressure –High always goes to low (When it can) Add heat to a wet surface increases its vapour pressure A 10ºC rise in temperature doubles the rate of evaporation

10. Heat Drying Systems TES System Dryair System Aquadry

11. Large Drying Systems Large Desiccants –Corroventa –Arid Dry Some add Heat –Concept

12. New Technologies Environmental Control Units –Heating –Dehumidification –Cooling

13. Which Method Is Best What are we trying to achieve Are the new systems Best –Where do we use them –Do they have issues Is there still a place for traditional methods

14. Any Questions Thank You
