R507 is an azeotropic blend of non-ozone depleting HFC refrigerants (R125 and R143a). It has similar properties and characteristics to R502 and R404A and can be used in similar applications at medium and low temperature, most typically industrial process chilling.
Although R507 is classed as an azeotrope we recommend that it should always be removed from the cylinder as a liquid when charging the system.
R507 is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) See oils section.
R507 has the potential to be used to retrofit some existing R22 pump circulation or flooded evaporator systems; however, it will be necessary to change the oil to a POE and some component changes may also be necessary. Any such conversion needs to be fully evaluated before proceeding taking into account the properties of R507.
R507 may be used to retrofit existing R502 systems; however, it will be necessary to change the oil to a POE.
