Refrigerants and lubricants
R407A
R407F
Refrigerant R407A is an HFC with similar
thermodynamic properties to those of R404A,
R407A is a zeotropic refrigerant and has a
temperature glide of about 6,6K. For more
specific information about zeotropic refrigerant,
refer to section “zeotropic refrigerants mixtures”
and read FRCC.EN.085. R407A must be charged
in liquid phase, Use of R407A allow to comply
with the new Fgaz regulation from 2015. R407A
GWP is stated at 2107 [CO2=1,0]. Always use the
Maneurop MTZ compressors with danfoss 160PZ
polyolester oil, which is supplied with the MTZ
compressors for R407A applications.
Refrigerant R407F is an HFC with similar
thermodynamic properties to those of R404A,
R407F is a zeotropic refrigerant and has a
temperature glide of about 6,4K. For more
specific information about zeotropic refrigerant,
refer to section “zeotropic refrigerants mixtures”
and read FRCC.EN.085. R407F must be charged in
liquid phase, Use of R407F allow to comply with
the new Fgaz regulation from 2015. R407F GWP is
stated at 1825 [CO2=1,0]. R407F is mainly suitable
for high & medium temperature application-
Always use the Maneurop MTZ compressors
with danfoss 160PZ polyolester oil, which is
supplied with the MTZ compressors for R407F
applications..
Hydrocarbons
Hydrocarbons such as propane, isobutane etc. are
extremely flammable. Danfoss does not authorize
the use of hydrocarbons with Maneurop® MT
or MTZ compressors in any way, even with a
reduced refrigerant charge.
