  Desiccant Selection Table
  	Medium Type	80% 3A desiccant and 20% active alumina	100% 3A desiccant
  Refrigerant	HFC	Applicable	Applicable
  		HCFC	Applicable	Applicable
  		CFC	Applicable	Not Applicable
  		HC	Applicable	Applicable
  Oil	Mineral oil or AB	Applicable	Applicable
  		Pure POE or PAG	Applicable	Applicable
  		POE or PAG with additive	Not Applicable	Applicable

  Note

  1. 1) For CFC system, usage of core with alumina is recommended as a strong capability to absorb acid may be needed.
  2. 2) When the systems use oil with additive, it is not recommended to use a core with alumina.

• Selection Formulas

  Filter Driers for liquid line are manufactured in compliance with ARI Standard 710. Maximum flow rate of liquid refrigerant at a differential pressure of 0,07bar (1psi) is indicated by kW (ton) which is based on the temperature of liquid refrigerant 30°C (86°F) and the following mass flow:

  • 0,40 kg/min/kW (3.1 lb/min/ton) R134a
  • 0,53 kg/min/kW (4.1 lb/min/ton) R404A, R507
  • 0,39 kg/min/kW (3.0 lb/min/ton) R22, R407C
  • 0,36 kg/min/kW (2.8 lb/min/ton) R410A

  Note: Data on water absorption is based on the following EPD (method: ASHRAE Standard 63.1):

  • 60ppm R22
  • 15ppm R12
  • 30ppm R502
  • 50ppm R134a, R404A, R507, R410A, R407C

  Note: The above data is based on clean system at ideal conditions; with impurities accumulated in the filter, the flow may decrease.
