Clean, Dry Compressed Air | MXLE

Large flow low energy modular compressed air dryers providing pressure dew points of -70°C and -40°C (-20°C option) with flow rates up to 2040 m³/hr @ 7 barg, even greater flow rates can be achieved by multi-banking the dryers.

Description

Adsorption Dryers

Whether a compressed air user wants to control the growth of micro-organisms (essential for direct and in-direct contact applications in the food, beverage & pharmaceutical industries), ensure air used for critical applications / instrumentation is free from water contamination or has external piping where low ambient temperature can cause condensation, adsorption dryers are the go to dryer technology.

There are many different adsorption dryer technologies available and whilst they all reduce water from the compressed air in the same way, they differ in the way they regenerate the desiccant material.

Vacuum Assisted Low Energy Adsorption Dryers

The simplest and most common method used to regenerate adsorbent desiccant material is the ‘heatless’ method (so called as it does not use heat for desiccant regeneration).

Using a proportion of the clean, dry process air for regeneration, heatless dryers typically have the lowest capital costs of all adsorption dryer types (due to the simplicity of the heatless design). Being very robust and having fewer components, they typically have the lowest maintenance cost of all the adsorption technologies.

Vacuum assisted Heatless Low Energy dryers maintain all the benefits and robustness of a standard heatless dryer whilst providing a reduction in the amount of process (purge) air and energy consumed.

Advantages

Parker MXLE dryers provide a constant outlet dewpoint in accordance with ISO8573-1 classes 1, 2 or 3 for water vapour
Parker MXLE dryers provide an outlet dewpoint which inhibits the growth of microorganisms (allowing their efficient reduction using filtration)
Parker MXLE dryers use clean, dry purge air for regeneration, eliminating any risk of damage to the adsorption bed or re-contamination of the downstream compressed air
Parker MXLE dryer performance has been tested in accordance with ISO7183, the international standard for compressed air dryer testing
No heat is used for regeneration; therefore, no insulation is required and loss of dewpoint on column changeover due to inefficient cool down is eliminated
Full feature electronic control with dewpoint display and Energy Saving Technology fitted as standard
Parker MXLE dryers include Parker OIL-X General Purpose & High Efficiency Coalescing pre-filtration and General Purpose Dry Particulate post filtration as standard
Parker MXLE materials of construction are FDA Title 21 CFR compliant & EX1935/2004 exempt
Specialist adsorbent fill method and modular design allow drying capacity to be easily increased should future air demand increase
Vacuum assisted regeneration provides 17% more air for downstream applications and energy savings up to 62% lower than an equivalent heatless model
Heatless fall back mode ensures dry compressed air is not lost if vacuum system is unavailable
