  Note:  

  1. the above data is based on clean system at ideal conditions; with impurities accumulated in the filter, the capacity may decrease
  2. R407C capacity is based on dew point conditions

   

   

  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), the evaporating temperature of

   -15°C (5°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, R507A

  •             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

  •             50ppm R134a

  •             50ppm R404A

  •             50ppm R407C

  •             50ppm R410A

  •             50ppm R507A
