EC-FX-NH3

A new and improved approach to
ammonia gas detection.

EC-FX-NH3
Sensor and Transmitter

introducing a

better, tougher

longer-lasting sensor

for industrial refrigeration

Breakthrough technology, only
from Honeywell Analytics.

In response to the challenging conditions
found in Industrial Refrigeration,
Honeywell Analytics has developed an
innovative new ammonia detector —
delivering reliability, accuracy and
long-lasting performance that you
can’t get anywhere else.

The EC‑FX‑NH3, an evolution of our
Manning EC‑F9‑NH3, features an
all-new ammonia sensor with a
proprietary electrolyte that stands up
to harsh environments.

So whether you’re monitoring
ammonia in blast freezers,
cold storage or engine
rooms, you can feel
confident in the
effectiveness of your
gas detection
system, helping
you ensure life
safety, prevent
food spoilage
and manage
costs.

Three harsh environments. One tough sensor.

If you use ammonia as part of your refrigeration process, you face several challenges in
protecting your plant from the danger and expense of ammonia leaks:

Cold Storage

From banana rooms to ice cream storage to food processing facilities,

your cold storage areas are subject to extremely low temperatures — plus

changes in humidity during cleaning and changes in pressure due to

opening and closing doors. These fluctuations can cause some ammonia

sensors to go into fault or false alarm. But since workers are often present

in these areas, it’s critical for ammonia sensors to stand up to tough

conditions and accurately report gas at low levels.

Refrigerated Processing Areas

Some of the harshest environments in the food industry are spiral freezers

and blast freezers, where rapid freezing often means drastic changes in

temperature. This temperature shock — along with humidity shock from

hot-water washdowns — can further challenge the resilience of your

ammonia sensors.

Engine Rooms

Finally, the most likely places for a catastrophic ammonia leak are often

your engine rooms, since they typically hold ammonia for use throughout

your plant. But in the hot conditions of most engine rooms, the liquid

electrolytes in standard ammonia sensor cells can dry out quickly,

sometimes reducing the sensor’s life span and causing false alarms.

Maintaining sensitivity and accuracy — even with rapid changes
in temperature and humidity

Creating a new standard of reliability in
ammonia gas detection

The EC‑FX‑NH3 is the next evolution of the
proven Manning Systems technology, which was
designed specifically for the extreme conditions
of fruit and vegetable processing, bakeries, meat
and poultry processing, beverage and bottling
plants, and more.

In fact, our Manning EC‑F9‑NH3 and
EC‑F2‑NH3 products have been the most­installed ammonia gas detectors in the
refrigeration industry. Now, with the all-new
EC‑FX‑NH3 from Honeywell Analytics, we’re
making that great technology even better.

isn’t it time you upgraded

to the most innovative, longest-lasting technology
for ammonia detection?

ammonia sensors, reduce your costs, and ensure the continued safety
and productivity of your plant.

EC-FX-NH3
Lifespan, Capabilities and Design

Longer life span.

Thanks to our proprietary technology, the EC‑FX sensor lasts up to 18 months longer than competitors
and we back it up with the longest warranty on the market. See how it compares:

Application Competing Sensors EC-FX-NH3

Cold storage and freezers Replace once or more every 2 years Replace once every 4 to 5 years

Engine rooms Replace every 6 to 18 months Replace once every 3 to 4 years

And if you’re using an ammonia gas detector from another manufacturer, you can potentially save even
more by switching to the EC‑FX‑NH3 transmitter with the all-new sensor. Over a 10-year period, you
can cut costs by up to $5,500 per sensor in the engine room and $2,800 per sensor in cold storage
and blast freezers.

Depending on the number of ammonia gas detectors in your operations, that longer sensor life
can add up to serious savings.

Robust capabilities with unique design

The EC‑FX‑NH3 responds quickly to ammonia gas concentrations in low parts per million (PPM). You
can count on this detector to stand up to the challenges of industrial refrigeration environments.

• Rugged construction for long-term reliability. Unlike fragile plastic housings that may break in cold
temperatures, the heavy-duty steel enclosure of the EC‑FX‑NH3 was built to withstand cold and wet
environments. The EC‑FX‑NH3 is also available in stainless steel.

™

• ATMOS
The EC‑FX‑NH3 automatically adapts to its environment and can operate in
humidity. So whether you’re monitoring ammonia in a banana room or a blast freezer, during dry conditions or
a hot-water washdown, the detector maintains accurate and reliable performance.

• SensorCheck
the electrical viability of the sensor every 24 hours. If there’s a problem, SensorCheck
controller — so you can rest assured that the sensor is operating properly.

• Optional LCD for real-time visibility. With an easy-to-read display, you can clearly see the ammonia
concentration at any given time. The optional display also makes it easy to set alarm levels and change
settings — all from the detector.

performance in ammonia gas detection.

CAUTION:

ECFX is designed for operation in a wide range of environments and harsh conditions. However, it is important that exposure to high concentrations of solvent vapors is avoided, both during storage, fitting into instruments, and operation.
ECFX is designed to be used in safety critical applications. To ensure that the sensor and/or instrument in which it is used, are operating properly, it is a requirement that the function of the device is confirmed by exposure to target gas
(bump check). Failure to carry out such tests on a regular basis may jeopardize the safety of people and property.

Three-Year Warranty

extended

three-year warranty

for the next generation in ammonia sensors

We stand behind our products. We are so confident in the performance of our new sensor that it
comes with a three-year warranty — twice the warranty of most competing sensors.

Our proprietary new EC‑FX sensor, backed by rigorous testing, was engineered to Honeywell’s highest
standards of safety, reliability and cost-effectiveness:

Stability you can count on.

Unlike other ammonia sensors, our new sensor maintains
sensitivity — even during rapid changes in temperature and
humidity. While other sensors may quickly lose sensitivity
after exposure to ammonia gas, our EC‑FX sensor bounces
back from alarm-level gas exposure and resumes accurate
detection. So you can rest assured that your ammonia
sensors are protecting lives and operations.

Lower cost of ownership.

Fewer sensor replacements means a lower cost of
ownership over time. In fact, if you’re currently using
our EC‑F9 or EC‑F2 transmitter, you can significantly
cut your costs by switching your current sensor for
the new EC‑FX sensor. Over a 10-year period, you
can save up to $2,500 per sensor in an engine room
and up to $1,300 per sensor in cold storage and blast
freezers.
