• 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, 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
  • 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.
