“If you change the way you look at things, the things you look at will change.”
So after reviewing that interesting comment, do you think that our industry is heading towards directed heat drying?
That question has been presented to many restorers nationwide and predominately the
Answer is YES! We can have many different viewpoints, but isn’t it interesting that the main manufacturers in our industry are now bringing heat drying equipment to the main stream and that all the NEW dehumidifiers for 2011 work between 70˚-120˚. Now let’s look at several of the many examples that demonstrate conclusively that IICRC S500 supports direct application of heat. Numbering refers first to the page, then to the section and subsection where this information can be found.
6.1.3 (Page 20) Restorers should manage both air & surface temperature in order to enhance drying and avoid potential related damage.
P. 52 12.1.23 “Applying Heat Directly to Materials – … thermal energy transfer and other systems employing direct heat application can be used to increase the temperature of wet materials…. Additional direct heat can accelerate drying of wet materials, especially, dense, less-permeable materials.”
P. 55 18.104.22.168 “Techniques for Drying Carpet & Cushion …Partial Floating: Carpet is disengaged at one corner and heated air is injected under the carpet but on top of the cushion. The carpet acts as an insulator to maintain heat in close proximity to wet surfaces.”
P.58 22.214.171.124.4 “Heat on materials – Drying walls, solid wood flooring or the underside of subfloors, such as plywood, can be accelerated using heat.”
This section also recommends the use of heat along with negative pressure (vac panels) for drying wood floors.
P.60 12.3.8 “After removing excess moisture, concrete should be dried using a combination of controlled dry air movements…or direct heat application.”
We could go on with many more quotations showing the current S500 standard recognizes, approves and even recommends heat based drying systems. But the above should be enough to make the point that the application of directed heat drying and the proven results are in harmony with S500 standards. So if you change the way you look at things, the things you look at will change.
