HFC Non ozone depleting refrigerants

HFCs (Hydrofluorocarbons) are non ozone depleting and the refrigerant of choice in a wide range of new refrigeration and air conditioning equipment. These refrigerants are non-flammable, safe, easy to use and energy efficient in the correct application. Refrigerant selection is usually made by the equipment manufacturer and will be dependent upon the application and operating conditions required.

DuPont^TM ISCEON® 9 Series Refrigerants are a unique range of easy to use, non-ozone depleting HFC retrofit refrigerants which can be used as direct replacements for HCFC's and CFCs in existing equipment. Each has been developed to avoid costly equipment replacement and can offer other benefits depending on the refrigerant.

IDS R134a
1,1,1,2-Tetrafluoroethane

R134a is a single component non-ozone depleting HFC refrigerant. It has similar properties and characteristics to R12 and is the refrigerant of choice for automobile air conditioning. It is typically a medium temperature refrigerant used in some domestic and commercial refrigeration applications, as well as transport refrigeration and large industrial chiller applications.
R134a is also used as a component in other HFC blends.

R134a is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) except for automotive air conditioning where Polyalkylene Glycol (PAG) oil is preferred. See oils section.

R134a can also be used to retrofit existing R12 or R401A and R409A systems; however, it will be necessary to carry out a number of oil flushes when changing to a POE.

Many users find that DuPont^TM ISCEON® MO49Plus (R437A) is easier to use for retrofitting direct expansion or capillary systems.

IDS R404A

R404A is a blend of non-ozone depleting HFC refrigerants (R125, R143a and R134a). It has similar properties and characteristics to R502 and is used in both medium and low temperature applications. It is widely used for commercial refrigeration applications, including display cabinets, cold rooms and ice machines, as well as transport refrigeration and industrial refrigeration.
As R404A is a blend it should always be removed from the cylinder as a liquid when charging the system.

R404A is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) See oils section.

R404A can also be used to retrofit existing R502 & R408A systems, however, it will be necessary to carry out multiple POE oil changes.

Many users find that DuPont^TM ISCEON® MO29 (R422D) or MO79 (R422A) are easier to use for retrofitting systems.

IDS R407A

R407A is a blend of non-ozone depleting HFC refrigerants (R32, R125 and R134a). It has similar properties and characteristics to R22 in some applications but should not be confused with R407C. It is typically used for refrigeration applications and offers a lower GWP alternative to R404A.

As R407A is a blend it should always be removed from the cylinder as a liquid when charging the system.

R407A is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) See oils section.

R407A may also be used to retrofit certain existing systems, however, it is rarely the first choice, as multiple oil changes to a POE is required.

Many users find DuPont^TM ISCEON® MO29 (R422D) is easier to use for retrofitting existing systems.

IDS R407C

R407C is a blend of non-ozone depleting HFC refrigerants (R32, R125 and R134a). It has similar properties and characteristics to R22 and is used across a wide variety of air conditioning applications. It is widely used for splits, VRF, and direct expansion water chillers.
As R407C is a blend it should always be removed from the cylinder as a liquid when charging the system.

R407C is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) See oils section.

R407C can also be used to retrofit some existing R22 air conditioning systems, however, it will be necessary to carry out a number of oil flushes when changing to a POE.

Many users find that DuPont^TM ISCEON® MO59 (R417A) and ISCEON® MO29 (R422D*) are easier to use for retrofitting systems.

IDS R410A

R410A is a blend of non-ozone depleting HFC refrigerants (R32 and R125). New equipment has been designed specifically to take advantage of its properties such as higher cooling capacity and negligible temperature glide.

It has become increasingly popular in many air conditioning and heat pump systems and in many applications is now preferred to R407C.

R410A equipment is usually more energy efficient.

Engineers should ensure they are equipped with the correctly rated gauges for R410A.
Although R410A is sometimes referred to as an azeotrope we recommend that it should always be removed from the cylinder as a liquid when charging a system.

R410A is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) See oils section.

R410A should not be used to retrofit existing R22 systems as they are not designed for the higher operating pressures of R410A.

Performax™ LT (R407F)

Performax LT is zeotropic blend of HFCs, intended for low and medium temperature commercial refrigeration applications.  It improves upon and can replace R404A in new and existing installations.

Performax LT increases the system's energy efficiency, allowing you to reduce energy consumption and lessen the overall impact on the environment.

IDS R507

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.
Many users find that DuPont^TM ISCEON® MO29 (R422D) or MO79 (R422A) is easier to use for retrofitting direct expansion systems.

IDS R508B

R508B is an azeotropic blend of non-ozone depleting HFC refrigerants (R23 and R116). It has similar properties and characteristics to R503 and is used for very low temperature applications, such as environmental test chambers and medical freezers.
Although R508B is an azeotrope we recommend it should always be removed from the cylinder as a liquid when charging the system.

R508B is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE) See oils section.

R508B can also be used to retrofit existing systems containing R503; however, it will be necessary to change the oil to a POE.

IDS R23
Trifluoromethane

R23 is a single component non-ozone depleting HFC refrigerant. It has similar properties and characteristics to R13 and is used in very low temperature applications. It is typically used in environmental test chambers and medical freezers.

R23 is not compatible with mineral oil. Equipment manufacturers recommend Polyol Ester oil (POE). See oils section.

R23 can also be used to retrofit existing R13 systems; however, it will be necessary to carry out an oil change to a POE.

IDS R125
Pentafluoroethane

R125 is a single component non-ozone depleting HFC refrigerant. It has the potential to be used in some low temperature applications but R125 is more commonly used as a component in other HFC blends.
R125 is not compatible with mineral oil.

Equipment manufacturers recommend Polyol Ester oil (POE). See oils section.
