NEQXUS Air Treatment, Refrigerated Compressed Air Dyer

NEQXUS Air Treatment QX-D Regenerative desiccant type dryer.

-40°C pressure dew point, residual moisture of 0,117 g/m³, optional down to -70°C dewpoint, residual moisture of 0,00269 g/m³

Regenerative desiccant type dryers use a porous desiccant that adsorbs the moisture by collecting it in its myriad pores, allowing large quantities of water to be retained by high density filled desiccant columns.

The most common dew point rating for these dryers is -40°C. While this level may be needed for sensitive processes or instrumentation, this level of dryness is not normally needed in general manufacturing unless the pipes are exposed to freezing temperatures.

The desiccant is contained in two separate towers. Compressed air to be dried flows through one tower, while the desiccant in the other is being regenerated. Regeneration is accomplished by reducing the pressure in the tower and passing purge air through the desiccant bed.

All of these dryers need filtration on the inlet to keep liquid water and oil from damaging and contaminating the desiccant. On QX desiccant dryers an integrated filter on the outlet catches the desiccant dust (that is generated from the constant movement of the desiccant beads against one another caused by flow of air through the dryer).

PATENTED COMBINED FILTER AND DESSICCANT CARTRIDGE

A built in inlet water separator (QX 5 D - QX 41D) eliminates the cost and pressure drop of installing a separate inlet water separator in small oil-free compressor applications.

Desiccant and outlet filtration are integreated into a single cartridge (eliminates the cost and pressoure drop of installing a separate after filter).

High density filled dessicant provides maximum adsorption capacity.

Easy to replace cartridges simplify maintenance requirements.

MORE GOOD REASONS TO CHOOSE A NEQXUS MODULAR DESICCANT DRYER

Optimum dew point performance

Dryers are provided as standard set for a -40°C dew point. Optional dew points from -20°C to -70°C are available

Floor or wall mounted

Simply by rotating the feet 90° (standard on QX 5 - QX 41, optional on QX 58 D to QX 301 D)

Constant Flow and Pressure

Pressure is equalized before switching columns to ensure uninterrupted compressed air and consistent air pressure. Equalization also ensures long desiccant life due to minimized desiccant attrition.

Maximum corrosion protection

High tensile aluminium columns are corrosion protected then externally powder coated to provide maximum protection for corrosive environments

HIGH PERFORMANCE VALVES

QX 5 D to QX 41 use integrated check valves and two pilot operated solenoid valves for proven performance and reliability.

QX 58 D to QX 301 D four use solenoid valves.

On QX 360 to QX 1886 D. Inlet, exhaust and outlet air are controlled using pilot operated coaxial flow valves integreated into the upper and lower manifolds. the valves provide unrestricted flow capacity and are designed for durability, ease of maintenance and long service life (picture).

TWO STAGE MAINTENANCE FREE SILENCER

Exhaust air is directed into easily maintained silencers behind the lower manifold. The air is then directed under the dryer away from oerators and traffic lanes in the compressor room

PLC CONTROLLED OPERATION

The dryers are operated by a robust and reliable PLC control system offering valuable features including ‘power on’, ‘hours run’ and ‘service required’ indicators

Memory retention built into the PLC enables the controller to pick up where it left off in the drying cycle, ensuring consistently clean and dry air downstream

Compressor synchronization is a standard energy saving feature which starts and stops the dryer with a signal from the compressor or point-of-use equipment to eliminate purge loss when drying is not required

UP TO 60% MORE ENERGIE SAVINGS (OPTION)

When the energy saving dew point control option is ordered, a dew point sensor is incorporated into the dryer providing the ultimate in energy savings.

The outlet dew point is constantly monitored allowing the cycle time to be adjusted depending on the actual moisture load saving valuable purge air

Note: Heatless desiccant dryers consume about 15 to 20 percent of their rating in purge air. Please ask our certiefied partners for advice, to select the drier, which suits exactly to your application and need. Perhaps it is better to use a QX adsorption dryer as an point of use dryer in particular critical areas, e.g. sensitive processes or instrumentation or if airpipes are exposed to freezing temperatures.
