Sonic provides efficient air knife designs to dry
or assist heater tunnels in the drying of continuous coated
product while reducing cost, complexity and size of traditional
methods. No matter what the product size, speed and coating
materials, Sonic designs solutions for a wide cross section
of industries. Whether aqueous or solvent based coatings,
there is a Sonic solution for you.
Reduce the size, energy consumption and dwell time
of heater tunnels that in many cases will trap the
moisture within the coating as a "skin" forms on
the coating surface. The result of trying to dry a coating
from the outside in is that the drying zone must be increased
in length or time to evaporate the remaining trapped moisture.
Running higher tunnel heater temperatures is not usually the
best option. Aside from the tremendous increase in operating
costs, the coating, a heat sensitive substrate or the mass
of a large part simply may not permit or benefit from more
heat. A Sonic air knife accelerates the natural evaporative
process by removing moisture from coating before the surface
pores of the coating are dried. This reduces the drying time
and allows the heater system, if required to complete the
drying or curing process, to operate much more efficiently
(lower total kW and BTU) and/or with less product to heater
dwell time.
