Looking for desiccant compressed air dryers? IATT offer a complete range of desiccant air dryers suitable for drying small to large areas. Air dryers are available at low cost throughout the UK

Dry, oil and particle free compressed air is vital to most compressed air systems used in industry. Compressed air dryer treatment with filtration is also essential. When it comes to drying compressed air, a compressed air Desiccant Compressed Air Dryer provides the ideal solution for the removal of residual water vapour to provide low dew points of -40° C/F and lower.

IATT offer two compressed air dryer technologies suitable for demanding purpose applications that meet the highest standards as specified in ISO 8573:1.

These two products are the Heatless Modular Desiccant Compressed Air Dryer and the Vacuum Regenerative Twin Tower Desiccant Air Dryer. The Heatless Modular Desiccant Compressed Air Dryer is more suitable for drying small to large volumes of compressed air to a typical pressure dew point of -40° C/F with other options for dryers producing PDP’s of -20°C to -70°C.

The Twin Tower technology is more suitable for drying air from -20°C to -70°C pressure dew point (PDP) capable of handling small to large flow rates of compressed air. The Twin Tower products are also incredibly energy efficient, have touch screen controls and also boast dew point control as standard.

Both of these variants are suitable for their own specific requirements, and you can view them below with more information on the pair in their corresponding links.

How Do Desiccant Air Drying Technologies Work?

To simply explain the process of desiccant air drying; wet air passes through the desiccant medium which in turn adsorbs the moisture. The desiccant medium has a fixed capacity when it comes to the absorbing of moisture before it must be dried out, or regenerated. To do this, the tower containing saturated desiccant medium is depressurized and the accumulated water is driven off.

How this happens depends on the type of desiccant dryer, which we have touched on above. We’re happy to discuss this kind of query as well anything else you might need to know about the products or services we provide, so please don’t hesitate to get in touch with our team of experts today.

The PSA process detailed above is similar to that of a nitrogen generator, however the adsorptive material inside the sieve isn’t made of carbon as is the case with nitrogen, but is instead comprised of zeolite. A unique aspect of zeolite and the reason it is ideal for oxygen generators is due to its ability to discharge retained nitrogen gas when the pressure within the generator is reduced. In essence, this makes it relatively simple to regenerator the medium for a further cycle of oxygen generation with an industrial oxygen generator.

We Supply a wide variety of lab gas generators & laboratory nitrogen generators for gases such as hydrogen and nitrogen. Nitrogen generators are available at low cost throughout the UK

High Purity Hydrogen Lab Gas Generators

The IATT AiroGen® Laboratory Generator rangeoffers a safe and simple to use efficient technology for high purity H2, N2 and ZERO AIR analytical grade laboratory gases. The technology makes the gas cylinder redundant and the high purity gases you require available as and when you need them. IATT AiroGen® Lab GasGenerators offer a module design and can also be stacked to meet compact storage requirements, this makes them perfect for usage within multiple generation applications.

What is Adsorption?

To fully understand lab gas generators and swing adsorption technology, we must first explore what adsorption is. Adsorption refers to a gas application such as nitrogen generation, and is the accumulation of molecules of oxygen and other trace gases.

This accumulation is used to form a thin film on the surface of a specifically selected solid, such as carbon, by intermolecular forces. The adsorption process involves a mass transfer and differs from absorption, where a specific fluid is dissolved by a liquid or solid. Adsorption is a reversible process and facilitates the constant use of the system to generate nitrogen on a sustainable scale for commercial use.

Nitrogen Generators and Nitrogen Generation Explained

Now, with the definition out of the way, let’s explore how nitrogen generators and the process of nitrogen generation work. PSA Nitrogen is generated the process of adsorption, where the adsorptive properties of specific media, such as a Carbon Molecular Sieve, are used. Oxygen and other trace gasses found through the process are consequently adsorbed onto the adsorptive media at varying portions, depending on the system pressure present. In turn, the nitrogen passes through the media because of the fact that its molecular structure is too large to infiltrate the fine permeability of the adsorptive media in question.

The system utilised within our lab gas nitrogen generators and the generationprocess in general is with two pressurisedtowers to contain the adsorptive media. Here, the clean dry compressed air enters at the bottom of one of the towers where oxygen, carbon dioxide, moisture, some hydrocarbons, and trace gases are adsorbed. Nitrogen then passes through the adsorbent media bed into a buffer tank, prior to the outlet where it is subject to additional filtration and pushedon for use in the analytic application. After a predetermined time which isdependant on the purity of nitrogen required, the tower switches to regenerative mode and streams the pressurised compressed air into the second tower.

This is where the term Pressure Swing originates and is put into action.

Then, the process begins again. The first tower finally depressurises, and the adsorbed oxygen and other trace gases are distributedand expended to atmosphere.

The AiroGen® Lab Gas GeneratorsRange includes:
PSA LC/MS NITROGEN GENERATORS
DS-PSA NITROGEN GENERATORS
HIGH PRESSURE NITROGEN GENERATORS
MP-AES NITROGEN/AIR GENERATORS
