R404A
R507
Refrigerant R404A is an HFC refrigerant with
thermodynamic properties comparable to
those of the CFC refrigerant R502. R404A has
zero ozone depletion potential (ODP = 0) and
is commonly accepted as one of the best R502
alternatives. R404A is especially suitable for
low evaporating temperature applications but
it can also be applied to medium evaporating
temperature applications. R404A is a mixture and
has a very small temperature glide, and therefore
must be charged in its liquid phase, but for most other aspects this small glide can be neglected.
Because of the small glide, R404A is often called
a near-azeotropic mixture. For more information
refer to section "zeotropic refrigerant mixtures".
For low evaporating temperature applications
down to -49°F, Maneurop® NTZ compressors
should be used. Refer to the NTZ selection and
application guidelines. For medium temperature
R404A applications, always use the Maneurop®
MTZ compressor with 160PZ polyolester oil which
is supplied with the MTZ compressor.
Refrigerant R507 is an HFC refrigerant with
thermodynamic properties comparable to
those of the CFC refrigerant R502 and virtually
equal to those of R404A. R507 has no ozone
depletion potential (ODP = 0) and is commonly
accepted as one of the best R502 alternatives.
As with R404A, R507 is particularly suitable for
low evaporating temperature applications but
it can also be used for medium evaporating temperature applications. R507 is an azeotropic
mixture with no temperature glide. For low
evaporating temperature applications down to
-49°F, Maneurop® NTZ compressor should be
used. Refer to the NTZ selection and application
guidelines. For medium temperature R507
applications, always use the Maneurop® MTZ
compressor and Maneurop® 160PZ polyolester oil
which is supplied with the MTZ compressor.
Refrigerant R134a is an HFC refrigerant with
thermodynamic properties comparable to
those of the CFC refrigerant R12. R134a has
zero ozone depletion potential (ODP = 0) and is
commonly accepted as the best R12 alternative.
For applications with high evaporating and
high condensing temperatures, R134a is the ideal choice. R134a is a pure refrigerant and has
zero temperature glide. For R134a applications
always use the Maneurop® MTZ compressor with
Danfoss 160PZ polyolester oil which is supplied
with the MTZ compressor.
R134a
R407C Refrigerant R407C is an HFC refrigerant with
similar thermodynamic properties to those of
R22.
R407C has zero ozone depletion potential
(ODP=0). Many installers and OEMs consider
R407C to be the standard alternative for
R22. R407C is a zeotropic mixture and has a
temperature glide of about 11
o
F. For more
specific information about zeotropic refrigerants;
refer to section "zeotropic refrigerant mixtures".
R407C must be charged in the liquid phase.
Always use the Maneurop® MTZ compressors
with Danfoss 160PZ polyolester oil, which is
supplied with the MTZ compressor for R407C
applications.
