New refrigeration condensing units for R404A
February 2005
Our new range of condensing units from Danfoss Maneurop have been
optimized for refrigeration applications using R404A or R507. Using
the latest versions of the renowned Maneurop hermetic compressors,
all units up to 8.5HP have a single condenser fan, whilst the 10,
12 and 13.5HP units have twin fans.
The Optyma range is divided into medium/high back pressure
units suitable for evaporating temperatures from +10C to -30C, and
low back pressure units suitable for -20C to -40C. The range covers
R404A duties from 1,766 to 19,849 watts at -10C, and from 992 to
6,639 watts at -35C. The M/HBP models are also suitable for use
on R134a or R407c.
Two cylinder M/HBP models are fitted with the new high efficiency
versions of the Maneurop MTZ compressor, whilst LBP models use the
new NTZ low temperature compressor.
All units include a crankcase heater, rotalok valves, liquid receiver,
dual HP/LP switch (which can be set to give either auto or manual
reset on the HP side), Gomax hose and a fully pre-wired electrical
box.
The new units will be available from April 2005, in addition to
the familiar twin fan Blue Star condensing units.
