DEHUMIDIFIERS IN KDH BODY

KDH dehumidifiers were designed with a thought of correctly done maintenance and anti-corrosion works. They are equipped with process fans which give appropriate pressure to the inlet dry air. Dehumidifiers are mounted in resistant, durable steel cabins, which allow to transport them easily both by forklifts and by cranes. Similar to all adsorption dehumidifiers, they are built basing on an adsorption rotor made of carbon soaked in silica gel. Thanks to this, maximal dehumidification effect can be achieved.

Advantages:

available in four sizes: 2600, 3500, 5000, 8000 m³/h
possibility to increase the static pressure to 1000 Pa
high dehumidification efficiency
stable construction – possibility to move by crane and forklift, easy to maintain and access all elements
dehumidifiers can work in the full humidity range (0-100%RH) and below zero temperatures (-25C to +40C)

Operating principle of KDH dehumidifier

The core of the adsorption dehumidifier is a silica gel drying rotor. Dehumidifying is done in the process part, where microscopic water particles are adsorbed at the rotor surface. Dry air is let to the process by the process air. Regeneration air is used to regenerate the rotor, which vaporizes water from the rotor after appropriate heating. The humid air is removed out. KDH dehumidifiers make use of rotor heat recovery to heat the initial regeneration air. This solution allows to save energy used to regeneration process.

ADDITIONAL EQUIPMENT:

mechanical humidity sensor to control the device
electronic humidity regulator to control the device
diffusers to separate dry air to connect channels with appropriate sections
frame is painted according to customer choice

ADSORPTION AIR DEHUMIDIFICATION

Adsorption dehumidification technology is the most efficient dehumidification method. It is characterized by high efficiency and durability. Adsorption, washable drying rotor is the most element of the device. It can work 10-12 years, depending on operation conditions. Humidity that is removed from the air is adsorbed at the rotor surface and it does not interfere with its structure, so the rotor maintains its drying features for a long time.

Adsorption dehumidifiers are distinguished from other solutions by the possibility to work within the full range of humidity (0 to 100% RH) and very wide temperature range, including temperatures below zero (-25C to +40C). Using adsorption dehumidifiers by LEWACO gives the option to achieve very low dew points (e.g. DP=-20C, DP=-25C for special versions).

Another advantage of adsorption dehumidifiers that is a result of their amazing durability is the possibility to achieve the effect of appropriate dehumidification with minimized amount of air necessary for this process. As a result, ventilation ducts and sizes are smaller.

Adsorption dehumidification basing on LEWACO devices can be used in all weather conditions, with all humidity levels, and guarantee efficient solution of the problem of humidity for long years.
