Aircel MDD-045N Point-of-use Air Dryer

The Aircel MDD series regenerative desiccant dryer makes a great point-of-use dryer that can run up to 12,000 hours before it's first scheduled maintenance.

The Aircel MDD Series is a very efficient Dryer that can be outfitted to fit different needs. First, the MDD series offers a multitude of additional energy saving control features, which allows the dryer to be linked with a compressor control system and reduces air consumption during periods of low demand.

Second, the MDD series is extremely easy to maintain. All desiccant beads come inside of pre filled cartridges. These cartridges can be replaced quickly and easily saving you valuable maintenance time. The MDD is not large in size can also be easily wall mounted to save space. The MDD desiccant Dryer is perfect for scfm ranges of 4 to 365.

Aircel MDD Benefits

• Economical to use
  • Aircel's high performance dryers provide a host of financial benefits such as an integral electronic drain and service interval indication, all of which are included in the standard dryer package.
• Clean & dry air
  • With XA grade 0.01 micron oil removal filtration (supplied as standard on all models), an integral 1 micron dust filter and a choice of -40¼C / -40¼F or -70¼C / -100¼F pressure dewpoints, Aircel MDD meets and exceeds the highest standards of purity as specified in ISO 8573:1-2001.
• Worldwide installation
  • The units can recognise any voltage between 100-240 VAC and also any voltage between 12 to 24 VDC, meaning the Aircel MDD can be operated anywhere in the world. All dryers are built to be fully compliant with all approvals. Standard voltage if 115V for online purchases.
• Intelligent processor
  • A feature of each unit is an intelligent built-in central processing unit (CPU). The optional software interface package provides a sophisticated system which allows for remote interrogation of the dryer. The CPU is serialized and is housed in an IP65 rated enclosure.
• Energy management
  • Aircel MDD offers a multitude of additional energy saving features. From a simple power on indicator through to a service warning light, the effective energy saving feature allows the dryer to be linked with a compressor control system and reduces air consumption during periods of low demand.
• Condensate management
  • Condensate management is essential to maximize dryer efficiency. Aircel MDD is supplied with an integral electronic drain valve which is operated and controlled by the CPU. This drain valve opens at the end of every cycle when an indicator illuminates and the CPU checks for any sign of malfunction in the dryer. Operation of the unit is viewed by the diagnostic control panel located on the front of each unit.
• Desiccant Cartridges
  • An improved desiccant cartridge design with integral handle facilitates a simple and clean change out procedure.

How the Aircel MDD Works

Aircel MDD is designed to provide a smooth, controlled, uninterrupted delivery of dry compressed air.

Wet air passes through a pre-filter and travels down to the bottom valve assembly. The air is then fed through the bottom of the desiccant bed and moves through the high performance desiccant until it becomes dry. On exit from the desiccant cartridge, the air is passed through the outlet valve assembly.

During this process, the dryer control system cycles the process air between the two desiccant towers. While one chamber is on stream removing water vapour, the other is being carefully depressurized in preparation for regeneration. The desiccant bed is regenerated by expanding a small amount of dry process air, or purge air, through the saturated desiccant.

Purge air passes to the atmosphere through the silencer, which is fitted to an exhaust valve. The chamber is then repressurized, with the control system assuring each chamber is at full operational pressure prior to changeover. This ensures a reliable and efficient operation. The air stream is switched and the cycle repeats on a continuous basis
