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 m/hr.

2. Features

Standard configuration

1) Adopts P.I.D. temperature controller toaccurately control regenerative temperature.

2)The dehumidifying system of the GD-H seriesfeatures two coolers to ensure a low return air

temperature and low dew-point.

3) Return air filter is mounted inside to ensure nocontamination to the honeycomb.

4) Adopt silica gel assorption honeycomb, with lowregenerative temperature of 150°C,which can savemore energy.

Accessory option

1)Centralized automatic control can be realized by optionally selected PLC touch screencontroller.

2)Optionally select dew-point monitor to realize dew-point real-time monitoring.

3)Optionally select drying heater and its temp. controller to work with drying hopper for material dehumidifying and drying.

4)Optional heat-resistant air pipe, cyclone dust separator with floor stand, oil filter are available.

5)Molecular sieve honeycomb rotor is optional to reach -50°Cdew-point.

3. 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 ofhoneycomb 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.

4.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.
