ADSORPTION AIR DRYERS MD 50-2500 (88-2500 l/s / 185-5297 cfm)

MD, the industry benchmark for adsorption dryersClean and dry compressed air: it is vital to power up your busy production environment. Containing moisture, aerosols and dirt

particles, untreated compressed air poses a substantial risk as it can damage your air system and end product. Incorporating

unique, patented technological innovations and extra energy-saving options, Atlas Copcos MD adsorption dryers provide you

with the clean, dry air you need to expand the life of your equipment and ensure the quality of your end product.

POWER GENERATION A FOCUS ON PRODUCTIVITYAll kinds of power plants rely on dry, clean compressed air to operate

pneumatically controlled valves and other components.

High-quality dry air is the key to achieving plant productivity and cost savings.

PHARMACEUTICALSA TIGHT CONTROL ON QUALITY Strict moisture control is key in the manufacture of most drugs and medicines.

To assure high-quality medicines, the presence of dry air in the processing

area and machinery is vital.

PROCESS AIRA CONTINUOUS FLOW OF DRY AIRHigh-quality dry air is vital for efficient pneumatic and instrumentation control.

A dependable stream of high-quality dry air is essential to ensure your

process continuity.

FOOD & BEVERAGEA RELIABLE SUPPLY OF DRY AIR Avoid any risk of contamination of your end product by using high-quality

dry compressed air.

Eliminate any moisture to safeguard your process air.

PROTECTING YOUR REPUTATION AND PRODUCTION

By removing moisture from compressed air with a pressure

dewpoint as low as -45C/-49F, MD adsorption dryers eliminate

system failures, production downtime and costly repairs.

DRIVING DOWN ENERGY COSTSWith the MD adsorption dryers, your energy costs are reduced to a minimum.

By using the compression heat to regenerate the adsorption dryer rotor, the only

energy required is the power to rotate the drum which is negligible in the complete

energy use. MD dryers are very environmental friendly as there is almost no power

consumption thanks to the high-efficient heat exchanger. Moreover, MD dryers have

an extremely low pressure drop thanks to the no-loss condensate drain and there is no

need for pre- and after-filtering which increases the quality of the dried air.

ASSURING YOUR PEACE OF MINDThrough continuous investment in our competent, committed and efficient

service organization, Atlas Copco ensures superior customer value by

maximizing productivity. With a presence in over 170 countries, we offer

professional and timely service through interaction and involvement.

EASY INSTALLATIONThe MD dryers have a small footprint thanks to the innovative all-in-one design: an

easy-to-service vessel with direct flange-to-flange mounting, a convenient lifting

eye, integrated EWD water separator and all inter-connecting piping to minimize

costly production downtime.

KEEPING YOUR PRODUCTION UP AND RUNNINGAtlas Copco's proven adsorption technology ensures maximum reliable

process continuity thanks to the use of high-quality materials, the simple

design to eliminate any risk of losses and advanced control and

monitoring for optimal energy efficiency.

HIGHLY EFFICIENT AT ALMOST NO COSTThe only energy needed is the power to rotate the drum, a mere 0.12 kW.100% flow capacity at the output.Temperature, pressure and dewpoint peaks are eliminated.

EFFICIENT WATER SEPARATIONEfficient condensate separator with ultimate separation efficiency even in low flow conditions.Reliable and effective condensate evacuation from the separation chamber via the no-loss condensate drain.

Thanks to their pioneering technology, MD dryers

ensure the lowest pressure drop and lowest energy

consumption for the highest possible efficiency

saving you time and money throughout the

production process.

Removing moisture from compressed air in the harshest conditions, Atlas Copcos MD adsorption dryers eliminate system

failures, production downtime and costly repair and service works.

PROVEN PEACE OF MIND Building on Atlas Copcos know-how and years of

experience with regards to compressed air solutions,

the MD adsorption dryer range is tested using the

most stringent methods in the industry. You can rest

assured at all times. In order to obtain ISO 9001 and

14001 certification, Atlas Copco thoroughly tests its

dryers during design reviews. As a result of the

synergy with the compressor production facility,

Atlas Copco is able to test the entire dryer range to

all flows. To further reduce any type of contamination

within your process and protect your equipment,

Atlas Copco presents a complete range of compressed

air filters when needed. A total quality air solution for

every application.

Supreme energy and cost savings

ALMOST NO ENERGY CONSUMPTION

Keeping a firm grip on costs is one of your main concerns. Atlas Copcos adsorption dryers stand for important energy savings

all day, every day, year in, year out. Taking technology to a whole new level, the MD dryers achieve maximum cost savings,

allowing you to conduct a truly efficient energy reduction strategy.

MAXIMUM ENERGY SAVINGS, AT ANY CAPACITY!EXTRA SAVINGS AT PARTIAL LOAD!Extremely low pressure drop reducing energy consumption of the air compressor.

The only energy needed is the power to rotate the drum, a mere 0.12 kW.

Heat exchanger technology for supreme energy savings.

No waste of compressed air thanks to no-loss condensate drain.

VSD (Variable Speed Drive) exactly matches the rotation speed of the drum to the flow delivered by the

connected VSD driven compressor in order to ensure an optimal dewpoint at every variable capacity condition

(option for MD 800-2500).

Whereas other desiccant dryer types can consume up to 15% of the compressed air, the MD dryer guarantees 100% flow capacity at the output.
