VMH Drying | Patented drying technology developed by kolb

The patented VMH (Venturi Mixed Hot air) drying technology is an exclusive development of kolb. A high volume flow of normal circulating air is blown into a venturi nozzle. The resulting differential pressure there (passively) sucks on a small amount of very high temperature air. The resulting air mixture provides for uniformly high drying temperature (adjustable between 45° and 90° / 120° Celsius) all over the process chamber.

Further advantages are robustness and very low cost of ownership. Energy is only needed for a fan and the heating of a very small amount of air; the rest is executed by pressure differences and air duct geometry.
