Refrigerant Pressure Tables / R407C
Saturation pressure (bar, absolute) by temperature — dew point & bubble point.
Dew point and bubble point differ — this refrigerant is a zeotropic blend with temperature glide. Use the point matching your measurement (evaporator/condenser side) for charge and subcooling calculations.
GWP100: 1774 (AR5/AR4 basis, as used in the Enthalio app).
