Specifying a humidity-controlled oven isn't as hard as you think.
Many heat processing applications require more than simply applying heat to a product to obtain the desired result. In some applications, it is beneficial to increase and control the relative humidity in the heating chamber. Examples include curing certain coatings on glass, drying sealants on aircraft parts, processing lead battery plates, paper processing, drying aluminum printing plates and curing special gasket material. The goal is to apply heat without subjecting the product to the full drying effect of convection heating.
When should you use humidity control? The answer depends on your process.
