The Danfoss Intelligent Purging System (IPS 8)
is a stand-alone, self-contained purging unit
designed to remove non-condensable gases
(NC gases = air and other unwanted foreign
gases) from industrial ammonia refrigeration
systems.
The IPS control can handle up to 8 purge points
automatically.
The ingress of NC gases into a refrigeration
system is inevitable, regardless of the refrigerant,
pressures, or temperatures. NC gases in the
system will result in a decrease in system
efficiency, both in terms of an increase in power
consumption and reduced cooling capacity.
Due to having a different density than ammonia,
the ingressed air will accumulate in specific areas
of the system, where it can be removed using the
Danfoss IPS 8.
The accumulation areas are identified in the
Connection locations section, along with
recommended connection principles.
The purger unit is an electronically controlled,
self-contained R452A refrigerant system that runs
independent of the main ammonia system and
with only one flange connection to the ammonia
plant.
The flanged opening allows the ammonia gas/
NC gas mix access to the purger’s heat exchanger,
where it is split into ammonia condensate and NC
gases. The ammonia condensate is returned by
gravity to the main plant, while the NC gases are
purged to the atmosphere through e.g. a water
bath.
Through the flanged opening, the purger unit
has access to the parameters from the ammonia
plant required for full electronic control.
The unit runs automatically in 24-hour cycles,
checking for the presence of NC gases and, if
present, removes the NC gases.
To regain and retain the design capacity of the
main ammonia system and prevent future air
accumulation, it is highly recommended to install
the Danfoss IPS 8.
Introduction

based on the Danfoss MCX controller platform
• Reduced power consumption of the ammonia
plant
• Automatic purging response to NC gases in the
refrigeration system
• Continuous and smart monitoring of
differential pressure between the system
refrigerant and the purger’s refrigerant
• Smart purging that minimizes refrigerant
(ammonia) release to the environment
• Self-contained unit operation, which functions
independently from the main plant
• An operation log for easy purging cycle data
monitoring
• Industry standard Modbus RTU
communication for remote monitoring and
system integration
• Reduced purging unit power consumption
compared to other units due to on-demand
operation only
• Self-diagnostics for both unit and system
operation to shut down in the event of
malfunctions
• Cost-effective installation with few mechanical
and electrical connections
• A fully brazed and leak-tested R452A cooling
system, minimizing leakage risks
• A plug-and-play stand-alone design, which
simplifies installation and commissioning while
reducing potential errors
