Modular Heatless Desiccant Dryers 5-300 m3/h (3-176 SCFM)

Our innovative modular desiccant dryers are compact, fully integrated units ideal at point-of-use, so you only pay to dry the air required for your operation. The dryers deliver ISO Class 2 dew point performance, with optional ISO Class 1 to help prevent corrosion, minimize production disruptions and losses due to moisture or contamination. Easy on-site maintenance puts your production line back on line quickly.
High Air Quality: High-performance desiccant technology delivers ISO Class 2 or Class 1 pressure dew point air for critical applications; high efficiency pre-filter and general Purpose after-filter protect desiccant and downstream air from oil contamination and particulates.


Reliable Operation: High-strength desiccant, durable valves and components and long cycles extend equipment life.


Reduced Energy Use: Low pressure drop design saves on energy costs and provides an economical drying solution. Energy Management System option for further energy use reduction.


State-of-the-Art Control: Easy to use, advanced microprocessor with visual display showing data in real time to maintain dryer performance at optimum levels, providing preventative maintenance alerts as well as protection notifications for efficiency and connectivity.


Easy Installation and Maintenance: With a compact footprint and low noise operation, modular dryers are suitable to be quickly installed right in the work environment and easy maintained, with preventative maintenance alerts

Drying process
  1. Compressed air stream with moisture enters the dryer from inlet valve, depending where the PLC sequence step is, this will be either the left or right column
  2. The compressed air gets dried going upward in the column through the desiccant media that adsorb water vapor
  3. From the exit valve, the dried air is delivered to the air system
Regenerating process
  1. Simultaneously to drying the compressed air in the other column, a limited amount of dried air is passed from the upper outlet valve and expanded to atmospheric pressure through purge orifice housed within the valve, to the regenerating column
  2. This regeneration air flows downwards through the saturated desiccant of the other column and regenerates the desiccant by  adsorbing the moisture  
  3. The expanded regeneration air containing the adsorbed moisture is discharged through the exhaust solenoid valve and muffler
  4. The sphere in the valve and its position, right or left, determines which column is drying and regenerating. The movement of the  sphere is driven by the pressure difference between the columns (pressure for drying column and atmospheric pressure for  regenerating column) driven by exhaust solenoid valves in the bottom part of the dryers
