One measure of desiccant efficiency is the ratio or percentage of water storable in the desiccant relative to the mass of desiccant. Another measure is the residual relative humidity of the air or other fluid being dried. The performance of any desiccant varies with temperature and both relative humidity and absolute humidity. To some extent
Compressor World is a superstore of air dryers, offering all types of compressed air dryers, refrigerated dryers, high temperature dryers, high pressure dryers, desiccant air dryers, membrane air dryers, nitrogen generators and medical grade dryers for hospital medical air.
This leaves the air that exhausts out of the dehumidifier still warm but drier than when it entered. Desiccant dehumidifiers work quite differently. Instead of using condensation on cold evaporator coils to remove humidity from air, desiccant dehumidifiers use a chemical called a desiccant to do so.
Blower purge dryers use a combination of air from an external blower, heat and minimal compressed air. Heat of compression dryers use the heat of the compression. CD BD The drying process 1 Wet compressed air flows upward through the desiccant which adsorbs the moisture, from bottom to top. The regeneration process 2 Dry air from the
Sullair Desiccant Dryers reliably remove harmful moisture and contaminants from compressed air, helping protect your compressed air system, machinery and downstream tools. How Sullair Desiccant Dryers have a dual tower design in which both vessels are filled with desiccant material. 1. Saturated, compressed air passes through vessel one
How Do Desiccant Air Dryers Work Unlike the more common refrigerated air dryers, desiccant air dryers do not work by cooling down the compressed air. Instead, they operate on a principle called adsorption. The desiccant air dryer contains an active desiccant material such as silica gel or activated alumina.
Properly sizing a desiccant air dryer is anything but obvious. Keep reading to learn how to get it right. Desiccant air dryers are designed for and needed to remove any water vapor that is found in compressed air. These dryers work without a heater and function to 40 degrees Fahrenheit, or less.
A regenerative desiccant compressed air dryer from Grainger can help you provide clean, dry air to your air compressor. A regenerative desiccant air dryer uses two cylinders containing desiccant, so that one can be used to take water vapor from the air while the other is being regenerated.
Quincy air dryers purify your compressed air with our proprietary QSorb desiccant product. This formula is an enhanced activated alumina compound, which provides improved absorption and a lower pressure drop that will improve the energy efficiency of your air compressor system.
Heated purge desiccant dryers use an external blower and heater while heatless purge systems use compressed air to remove excess moisture, cycling through wet and dry sets Refrigerated dryers work to cool the air supply to about 38 degrees, to which water vapor condenses into a liquid and is expelled from the system
For the highest quality and service contact CDA Systems. We work directly with SPX Flow to deliver superior heatless desiccant air dryers with time proven reliability and optimal energy savings. The SPX Flow Hankison Heatless Desiccant Air Dryers HH Series includes the HHS, HHL and HHE series with flow rates from 40 SCFM to 5,400 SCFM.
Purge air requirement can range up to 18 of the total airflow. The typical regenerative desiccant dryer at 100 psig has a pressure dew point rating of 40F but dew points down to 100F can be obtained. Heat reactivated regenerative desiccant dryers may have internal or external heat applied by heaters.
This technology is a good choice when the compressed air is subject to freezing conditions. There are two types of desiccant dryers heated and heatless. Heated desiccant dryers use heat to remove water vapor from the desiccant material not in use at that point in the cycle. These dryers need large amounts of steam or electricity to operate.
BD desiccant air dryers are also available in a zero purge variant. CD heatless desiccant air dryers are the simplest and only use only compressed air as a purge, minimising electrical connections. XD with zero purge cooling uses the heat of compression recovered from the compressor for the regeneration of the desiccant. The XD dryer does
Refrigerated Dryers, Desiccant Dryers and Filters Air quality can have a significant impact on compressed air systems. Properly treated compressed air, and the right air dryer, will improve productivity, system efficiency, and product or process quality. Choosing the appropriate air dryer and compressed air filter is very important.
Two separate systems condition the air An oilremoval filter traps 99.9 of all oil aerosols and a desiccant system removes water vapor. An outlet screen keeps desiccant particles from entering the airstream, protecting air tools. The desiccant changes color when it needs to be changed or recharged, providing an easily visible reminder.
Most desiccants don39t chemically combine with water or the other substances they39re present to protect against. They capture them through adsorption, and stow them away where they can39t cause harm to the product. How Do Desiccants Work It is important to understand how the desiccant does its job of protecting the product.
Desiccant Dehumidification from Munters. Munters desiccant dehumidification systems remove moisture from the air by using a desiccant a material which easily attracts and holds water vapor. Desiccant dehumidifiers are especially wellsuited for removing moisture from air at a low temperature and low humidity level.
The desiccant cartridge removes 95 of the water vapor from the pressurized air. Most of the dry air exits the desiccant cartridge through a builtin single check valve and fills the purge volume between the desiccant cartridge and outer shell. Some air exits the desiccant cartridge through the purge orifice near the check valve.
