Features
With its unique scroll design and manufacturing
process exibility, the new Danfoss MLZ/
MLM refrigeration compressor oers a highly
ecient solution for demanding refrigeration
applications.
This new family of refrigeration compressors
includes 12 sizes of medium temperature
scroll compressors designed for commercial
refrigeration applications. These compressors
are engineered for refrigeration, and oer
cooling capacity from 3.4 to 21 kW (2 to 10 HP)
at common voltages and frequencies as well
as any of the common refrigerants (R404A -
R134a - R507 - R22 - R407A - R407F) (Only motor
code4.code5 of MLZ are qualied with R407A/
R407F). MLZ are only qualied with the above 6
refrigerants, MLM is to be used only with R22. Be
sure you have selected a qualied refrigerant for
this range of compressors.
Thanks to its dedicated refrigeration design, the
MLZ/MLM scroll compressor delivers a number
of powerful advantages. With its high eciency
motor and optimised scroll design it reduces
energy cost in normal operating conditions and
delivers high capacity and an optimised pressure
ratio for refrigeration applications.

Scroll compression principle
Danfoss scroll compressors are manufactured
using the most advanced machining, assembly,
and process control techniques. In design of
both the compressor and the factory, very high
standards of reliability and process control
were rst priority. The result is a highly ecient
product with the highest reliability obtainable,
and a low sound level.
The entire scroll compression process is
illustrated below. The centre of the orbiting scroll
traces a circular path around the centre of the
xed scroll. This movement creates compression
pockets between the two scroll elements.
Low pressure suction gas is trapped within each
crescent-shaped pocket as it forms; continuous
motion of the orbiting scroll serves to seal
the pocket, which decreases in volume as the
pocket moves towards the centre of the scroll
set, with corresponding increase in gas pressure.
Maximum compression is achieved, as the pocket
reaches the discharge port at the centre.
Scroll compression is a continuous process:
when one pocket of gas is being compressed
during the second orbit, another gas quantity
enters a new pocket formed at the periphery, and
simultaneously, another is being discharged.

connections
MLZ / MLM scroll compressors come equipped
with a threaded oil sight glass with 1"1/8 - 18
UNEF connection. It can be used for a visual
check of the oil amount and condition or it may
be replaced by an accessory oil management
device. The oil level must be visible in the sight
glass during operation.

Electrical data, connections and wiring
MLZ/MLM scroll compressors are available in 6 dierent motor voltages.Motor voltage
The compressor terminal box IP rating according to CEI 529 is IP22 for all models. IP ratings is only
valid when correctly sized cable glands of the IP rating is applied.
• First numeral, level of protection against contact and foreign objects
2protection against object size over 12.5 mm (ngers of similar)
• Second numeral, level of protection against water
2protection against dripping water when tilted up to 15°
The IP rating can be upgraded to IP54 with accessory kit (see section Spare parts & Accessories).
IP rating
MLZ/MLM scroll compressors will only compress
gas while rotating counter-clockwise (when
viewed from the compressor top). Since
single-phase motors will start and run in only
one direction, reverse rotation is not a major
consideration. Three-phase motors, however,
will start and run in either direction, depending
on the phase angles of the supplied power. Care
must be taken during installation to ensure that
the compressor operates in the correct direction
(see “Phase sequence and reverse rotation
protection”).
The drawings below show electrical terminal
labelling and should be used as a reference
when wiring the compressor. For three phase
applications, the terminals are labelled T1, T2, and
T3. For single-phase applications the terminals
are labelled C (common), S (start), and R (run).
The terminal cover and gasket should be installed
prior to operation of the compressor. Respect the
"up" marking on gasket and cover and ensure
that the two outside tabs of the cover engage the
terminal box.
