honeycomb desiccant honeycomb rotor

The effective of plastic materials down to the optimum residual moisture is of great importance for the production of high quality products. We offer desiccant and/or hot air drying systems for all free flowing plastic materials and in various capacity ranges.

 1.  Application scope

GD-H series honeycomb dehumidifiers are mainly used to dry hygroscopic engineering plastics. A honeycomb-rotor is used to offer effective drying, which under ideal conditions, can supply dehumidified dry air with a dew-point lower than -40°C.This series comprises 14 models of honeycomb dehumidifiers, the largest of which can provide dry air up to a quantity of 3,000 m³/hr.

What is honeycomb rotor?

The main part of honeycomb rotor is made by ceramic fiber and organic additives, sintered under high temperature with molecular sieve and silica gel as basic material to bond to-gether with inside of honeycomb to form the honeycomb like structure. Honeycle rotor offers unlimited long service life and can be cleaned. The moisture of return air is quickly absorbed by molecular sieves when passing through numerous holes within honeycomb rotor.So when coming out of rotor,can form low dew-point dry air. Regenerating and dehumidifying have similar principle and run simultaneously. The only difference is that the two process winds are in opposite direction.

2.   Working Principle

The moisture contained in the air which is waited for treating) will be absorbed by hygroscopic materials, hereafter, be de-absorbed by the regenerated hot air. And the two airstream work together in the rotation wheel. So, with the rotation of the wheel, moisture will be absorbed and de-absorbed continuously, and drain out via de-absorbing by regenerated air to form a steady low dew point airstream for using.
