Desiccant dehumidification systems

There are two main forms of desiccant media, one liquid and the other dry. Basic desiccant dehumidifiers or custom total environmental control systems that use an external energy source (typically natural gas or steam) to reactivate the desiccant wheel for more precise or low dew point applications. Numerous desiccant wheel sizes are available to match the dehumidification.

If the system provides both comfort cooling and dehumidification for the space, investigate the benefits of using a desiccant when the required supply-air dew point is below 50°F. In an environment at 80° F and RH it removes only pints of moisture per day.

This same variance in moisture removal rate is also present in consumer grade compressor based dehumidifiers. These systems include the latest innovations for absorption desiccant rotors and use the new energy saving system (Dessica’s patent). This new feature optimizes the rotation speed of the desiccant rotor in correlation with the evolution of the temperature and humidity conditions of the air to be treated.

Typically, a desiccant dehumidification system is utilized for applications below RH down to RH. Thus, in many applications, a DX or chilled water pre- cooling coil is mounted directly at the dehumidifier inlet. In these integrated designs, the desiccant system works as a pre-conditioner for outside (ventilation) air to remove the latent load.

Other applications of desiccant dehumidification are in ice rinks, hotels and motels, office buildings, full-service and fast food restaurants, medical facilities, and retirement homes. The thermally driven cooling cycle is a combination of evaporative cooling with air dehumidification by a desiccant, i.

For this purpose, liquid or solid materials can be employed. Our equipment removes moisture from the air, which allows you to control humidity in your buildings and industrial processes to very low levels. Our equipment is used by more than major industries which use our products for more than 1different applications. Alfa Laval Kathabar dry desiccant systems use a standard dew- point sensor to control the discharge and return air humidity precisely. Below is a general description of our standard control sequence for each reactivation type.

Custom control sequences can be developed on an application basis. Kathabar is the leader in liquid desiccant dehumidification products and systems. We manufacture and service desiccant dehumidification systems. It is used to control humidity in commercial buildings and industrial processes by using a desiccant to remove moisture from the air. HZ DRYAIR has been providing integrated environmental solution and systems with superior performance for China.

Humidity control is a critical aspect of treating air for air conditioning and air used in manufacturing or other non-standard processes. Dehumidification Technologies. Moisture affects building materials, the comfort of building occupants, an in many cases, the work performed in the facility — particularly if the function.

Bry-Air manufactures desiccant dehumidifier products for technically complex applications with mission critical requirements. Shop The Product Experts In Air Compressors. All our industrial desiccant dehumidification systems now include the advanced D- Max silica gel rotor as standard.

The D-Max manufacturing process includes the synthesizing (chemical bonding) of the silica gel to the rotor structure, resulting in a silica gel rotor of superior quality and exceptional longevity.

Our dehumidifiers are custom built, with programmable systems tailored to the specific needs. The boundaries of these systems are typically dictated by the temperature and the dew point. This desiccant (silica gel, molecular sieve, or activated alumina) is impregnated into paper sheets which are then wound into a wheel (called the rotor). A new technology, close to market introduction, are desiccant cooling systems using a liquid water- lithium chloride solution as sorption material. This type of systems shows several advantages like higher air dehumidification at the same driving temperature range of solid desiccant cooling systems ,. The best system for cold storage depends on the type of food store the location of the storage unit and its size.

The operation of the DH-1desiccant system is based on two counter current air streams flowing through a rotating desiccant wheel. Return air from the conditioned space is drawn through the rotating desiccant wheel. The desiccant adsorbs moisture from the air stream and the dry supply air is returned to. The addition of the CDQ desiccant wheel to the system enhances the dehumidification performance of the traditional cooling coil. The CDQ wheel transfers water vapor, and the cooling coil does all the dehumidification work in the system.

Advantix Systems Smarter dehumidification and cooling There are also non-energy, IAQ considerations to compare between approaches. Supplier High Quality, Competitive Price! Solid- desiccant systems are similar to liquid- desiccant ones in that they have a conditioner and a regeneration section.

Solid- desiccant dehumidification systems feature a rotating wheel constructed of solid- desiccant materials, such as silica gel. In a typical dry desiccant system , the desiccant is mounted on a rotating wheel. DESICCANT DEHUMIDIFICATION PERFORMANCE LESSONS Michael K. Building Systems Scientist Advantek Consulting, Inc.

The comparison between desiccant dehumidification system and conventional vapor compression air-conditioning systems is listed in Table and CACS stands for central air-conditioning system , while LDDS stands for liquid- desiccant dehumidification system. Desiccant dehumidification system is an alternate option against conventional dehumidification system in hot and humid climates. Conventional dehumidification systems have many drawbacks that include high power consumption and increase the chlorofluorocarbon (CFC) level in the environment and major contribute to depletion of ozone layer.

Used in a broad array of applications, Cargocaire dehumidifiers provide the humidity control required in many process and technical manufacturing situations. Munters manufactures and services Cargocaire desiccant dehumidifiers and dehumidi-fication systems. Off Sitewide Using Code FRIENDS20.

Allergy Buyers Club - Your Online Destination For Healthy-Home Products. Kathabar liquid desiccant dehumidification systems operate on the principle of chemical absorption of water vapor from air. Special holding frame from both sides of the desiccant wheel prevents the mixing of the process air and the reactivation airflows. Moreover, the absence of condensation during the dehumidification process allows installing the desiccant dehumidifier , without a connection to drainage system.

A desiccant -based system can be a very cost effective method of dehumidifying building ventilation air streams. The simulation conducted for this research compared using a small chiller or a desiccant system for the dehumidification process. The condenser waste heat from the refrigeration cycle is captured and used to regenerate the desiccant wheel in order to achieve further dehumidification.

Aggreko offers two types of industrial dehumidifier rentals: refrigerated and desiccant. Refrigerated drying works best with a strong temperature differential, which means that refrigerated dehumidifier rental units are most effective at high ambient temperatures and high humidity.
