Duct dehumidifier

Duct dehumidifier

Duct dehumidifiers are commercial dehumidifiers of high capacity. These are connected and operated through ducts. the ducts can be either dedicated ducts or existing ducts of HVAC.

What is the principle of Duct dehumidifier?duct-dehumidifier-installation-method

Most of our commercial dehumidifiers of high capacity can be connected to ducts. In principle, the air intake will be through intake ducts. The outflow duct from the room will be connected to the intake of the dehumidifier. The dehumidifier processes the air and removes the moisture content. The outlet air from the dehumidifier is connected to the inflow duct.

The outflow ducts and inflow ducts will be distributed in the building, auditorium, cinema hall etc. The air is continuously collected from the room, processed and returned to the room. The air coming from the dehumidifier will be dry air. Thus, the humidity of the room is reduced.

The dehumidifier can be either desiccant or condensation type. The condensation type absorbs water through condensation process. The water thus collected is drained through a drainage pipe.duct-dehumidifier-Dubai-Model-DH300BY

The desiccant type absorbs moisture through a material known as desiccant. After passing through desiccant, dry air and wet air are separated. The dry air is directed back into the room and wet air is thrown out of the room. It has to be noted that part of the air does not come back to the room and hence pressure is reduced. This has to be compensated.

Which is the best duct dehumidifier?

We have 4 of our best duct dehumidifiers being supplied in Dubai and other Emirates of UAE. They are described here.

  1. Model DH 150 AX / 150 BXduct-dehumidifier-Dubai-Model-DH150AX
  2. Dehumidification capacity at 30 °C &  80 % RH will be 250 liter per day.

    Dehumidification capacity at 20°C / 60 % RH will be 110  liters per day.

  3. Model DH 300  BX
  4. Dehumidification capacity at 30 °C &  80 % RH will be 520 liters per day.

    Dehumidification capacity at 20°C / 60 % RH will be 110 220 liters per day.

  5. Model DH 300  BYchart-of-duct-dehumidifier-DH600BY
  6. Dehumidification capacity at 30 °C &  80 % RH will be 520 liters per day.

    Dehumidification capacity at 20°C / 60 % RH will be 110 220 liters per day.

    This model can operate upto -15°C.

  7. Model DH 600 BY

Dehumidification capacity at 30 °C &  80 % RH will be 1,040 liters per day.

Dehumidification capacity at 20°C / 60 % RH will be 440 liters per day.

All of the above are condensation types. As you can see the outlet is on the top side. This can be connected to a duct as shown in the image. The inlet is on the back side and also can be connected to a duct. The inlet has a filter also. So you have to connect with a provision for cleaning the filter. Additionally, it is preferred to provide an air filter at the intake point at the room itself. This will further clean the air before reaching the dehumidifier.
