When in use, the DriTec Dehumidifier draws in air from

a room through the air inlet. This air passes through the hon-

eycomb channels of the rotor. As this happens, the desiccant

material captures most of the moisture present in the air.

Once this "process air" has been dried out, it is vented back

into the room.

As the rotor captures water vapor from the air, it be-

comes saturated with water. The saturated rotor eventually

loses its ability to capture additional moisture. The process

of removing this water from the rotor is called

"reactivation."

Reactivation Air

During operation, a portion of the rotor is constantly be-

ing dried or "reactivated." In the DriTec, heated air is di-

rected to the reactivation sector and is forced through the

channels in that portion of the rotor. The heated air releases

the moisture captured in the desiccant material. The moisture

is discharged into the heated "reactivation air stream" and is

then vented from the unit to the outdoors. As the DriTec

operates, the rotor slowly turns so that only a portion of the

whole rotor is exposed to the heated reactivation air at any

one time.

At this point, the moisture has been removed from the

room, stored on the rotor, and then released from the rotor

into the outside air. The desiccant dehumidification process

cycle is complete.

Here is a quick review of the operation:

1. Moist process air is drawn into inlet and through the de-

humidifier.

2. Moisture in the process air is captured on the desiccant

rotor and the dry process air is vented through process

outlets back into the room.

3. Reactivation air is heated within the dehumidifier.

4. The wet area of the rotor turns into the reactivation sec-

tor.

5. The moisture in the desiccant rotor is released into the

heated reactivation air.

6. The reactivation air, laden with moisture, is vented

through the reactivation outlet to the outdoors.

7. The reactivated rotor rotates into position to capture

more moisture.

OPERATING CONDITIONS

The DriTec Desiccant Dehumidifier effectively removes

moisture at virtually any job temperature without the freeze-

up problems associated with refrigerant dehumidifiers. Low-

temperature operation is one advantage of using desiccant

technology.

The DriTec dramatically reduces ambient humidity to

very low levels not obtainable with refrigerant dehumidifi-

ers. This allows faster and more thorough drying of dense

materials like hardwood flooring and structural woods.

The DriTec also uses improved technology that removes

humidity When a desiccant dehumidifier is first put into

operation in a saturated environment, it will constantly re-

duce humidity. Its rate of water removal is determined by the

volume of the area, the environmental conditions, and the

capabilities of the machine.

Saturated Environments

On many restorative drying jobs, the initial humidity is

very high as porous materials like carpet and cushion give

up moisture to the air. However, as the job progresses and

humidity levels fall, moisture may need to be evaporated

from less porous materials including drywall and wood.

Refrigerants are most effective when both humidity and

temperature are high. They are much less effective in ambi-

ent conditions under 50% relative humidity or 50°F (10°C).

Desiccant dehumidifiers are generally effective in all ranges

of temperature and humidity.

In saturated environments it is often helpful to use the

DriTec Desiccant together with refrigerant units to speed the

drying process. In these conditions the DriTec removes wa-

ter as well as a comparable refrigerant unit. Also, it is actu-

ally more cost effective. (For example, a 25-gallon/day

refrigerant dehumidifier that costs $2,195 removes water at

$87.80 per gallon. The 48-gallon/day DriTec 325 that costs

$3,699 is removing water at $77.06 – a cost savings of over

$10/gallon.)

Lower Levels of Humidity

When the relative humidity falls to 40%, a refrigerant

dehumidifier will remove little additional water. At this

point many materials in the room such as carpets and wall

surfaces may feel dry, but moisture may remain in structural

materials. Ceilings, walls, and structural flooring materials

typically take longer to dry. The DriTec Desiccant is supe-

rior for drying these materials. It has the capability to lower

humidity over time to below 1% Rh. The low humidity envi-

ronment created by the DriTec speeds the drying of struc-

tural materials which dry very slowly in conditions of

normal, comfortable humidity.

The DriTec Desiccant also can be more cost-effective

than refrigerant dehumidifiers in low-temperature condi-

tions. The DriTec continues to remove moisture at tempera-
