The Maneurop® NTZ series from
Danfoss Commercial Compressors
is a range of hermetic reciprocating
compressors for low evaporating tem-
perature applications. These compres-
sors gradually replace the existing LTZ
range.
The NTZ series is engineered as a true
low temperature compressor, opti-
mised at –35°C with an extended
evaporating temperature range from
–45°C up to –10°C. The compressors
can be operated at a return gas tem-
perature (suction gas temperature)
of 20°C even at low evaporating
temperatures.

A liquid injection system is not re-
quired. All components are of high
quality and precision to assure a long
product life.
NTZ compressors have a large internal
free volume that helps to reduce the
risk of liquid hammering. The electri-
cal motor is fully suction gas cooled
which means that no additional body
cooling is required and it allows the
compressor to be insulated with an
acoustic hood when the installation
requirements call for extra low sound
characteristics.
