  Note:

  • 1) Please contact Sanhua representative regarding applications with HFO
  • 2) For flammable refrigerants only solder versions with tube connections below 25 mm (1 inch) can be used
  • 3) 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), 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
