New FR(II) Series

For High productivity, low maintenance and low operation cost of pneumatic applications

Why dry compressed air is necessary

• Compressor suction air in industrial facilities is contaminated by large quantity of foreign particles, by which the largest proportion belongs to water vapor. Water content in compressed air causes wear, corrosion and damages on the pneumatic machinery, tools and equipment, which further affects quality of production process and increases operational cost of complete system.
• Through the means of after-coolers, separators and condensate drains, the condensate can be removed up to 70-80%, but refrigerant air-dryer effectively eliminates all the remaining humidity and supplies compressed air suitable for all pneumatic applications.

Importance of Proper Refrigerated Air Dryer Selection

• The right choice of type and size of a refrigerated air dryer will not only ensure them most effective and reliable operation, but will also enable the most efficient and lowest operation cost utilization.
• An undersized refrigerated air dryer will not be able to dissipate the heat of compressed air and efficiency of the drying process will be impaired.
• An oversized refrigerated air dryer will cause continuous modulation in order to comply with the condition of air, causing operational problems and increased wear and tear of dryer components.

It is important to know the actual working conditions and consumption of the system:

Compressed air flow rate
Working pressure
Maximum compressed air inlet temperature
Maximum ambient temperature

Stainless-Steel heat exchanger shell

• Rust free interior
• Raises efficiency and extends service life
• Diminishes automatic drain corrosion and filter clogging
• Compact design of integrated 1st and 2nd heat exchangers

High heat-exchange efficiency

• Counter-flow design extends heat exchange time,
  increases efficiency and leads to lowest Dew-point.
• Cross stream flow delivery method has no large orifice obstructions
  and air pressure loss is reduced to minimum,
  while the most effective moisture extraction is achieved.

Low pressure loss

• Saving energy by reducing clogging and pressure
  drop (under 2.8 PSI or 0.2 kg/cm2)

Ozone-friendly refrigerant

• R134a or R407C refrigerant

Nickel-plated brass pipe

• Anti-corrosion and long service life properties
