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.
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?

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.
Technology for environmental flexibility.
‑50°F and 100 percent
Technology for peace of mind. The EC‑FX‑NH3 is equipped with a microprocessor that checks

• Backwards compatible. The EC‑FX sensor is backwards compatible with both EC‑F9‑NH3 and EC
‑F2‑NH3.
Add it up, and our new EC‑FX‑NH3 gas detector — housing an all-new, proprietary ammonia sensor from Honeywell Analytics — is the new gold standard for reliability, accuracy and long-term 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.
EC-FX-NH3 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.
