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.

Features
• 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
HOW IT WORKS

DRYING PROCESS
• 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
• The compressed air gets dried going upward in the column through the desiccant media that adsorb water
vapor
• From the exit valve, the dried air is delivered to the air system

REGENERATING PROCESS
• 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
• This regeneration air flows downwards through the saturated desiccant of the other column and regenerates
the desiccant by adsorbing the moisture
• The expanded regeneration air containing the adsorbed moisture is discharged through the exhaust solenoid
valve and muffler
• 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
