Gas Detection

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
