SUPERIOR™ Ammoniator Series NHM-1
Direct Cylinder Mounted - All Vacuum
GENERAL DESCRIPTIONThe SUPERIOR™ Series NHM-1 Ammoniator is a state-of-the-art,
vacuum-operated, solution feed type which mounts directly on aAmmonia cylinder valve. The chlorinator is mounted onto theAmmonia cylinder valve using a very heavy-duty, positive yoke clamp
connection. A Ammonia gas flow meter indicates the amount ofAmmonia being fed. Ammonia flow rate is manually adjusted and thedesign permits easy addition of a number of automatic flow rate
control devices. A high efficiency, water operated ejector produces
the vacuum necessary to operate the system. The ejector assembly
contains a back-flow check valve system to prevent pressurized waterfrom entering the chlorinator. A spring-opposed diaphragm vacuum
regulator controls the Ammonia gas flow rate and also acts as thesafety shut-off valve.

10. PVDF vacuum tubing fittings are standard..anotherSUPERIOR™exclusive. "User friendly" design makes it easy to attach
tubing, and to tighten or loosen ferrule nuts without tools.
11. Fewer parts, combined with superior materials and a superior
design gives you a SUPERIOR™ Ammoniator.

FLOW METER CAPACITIES

Variable area flow metering tubes are available with dual
English/Metric scale maximum capacities of 0.8, 1.5, 4, 10, 25, 50 and
100 pounds per 24 hours of Ammonia gas, as well as 15, 30, 75, 200,500, 1000 and 2000 grams per hour, respectively. All metering tubes
are interchangeable and may be changed in the field without specialtools.

MODULAR DESIGNFEATURESThe SUPERIOR™ Series NHM-1 represents the most modern design
technology coupled with the very
best materials available to create an
outstanding, user friendly piece ofequipment. It is designed with user
safety as a primary concern.
1. A new ultra-thick, fluoroplastic
yoke coating gives SUPERIOR™
corrosion resistance, won't crack,peel or chip. Ammonia will not
diffuse through it to cause coating
bubbling and peeling.
2. All molded parts are fiber-glass
reinforced ABS plastic, designed forSUPERIOR™ strength, warpresistance and Ammonia resistance.

SUPERIOR™ Ammoniators have been designed to give maximum
flexibility in system installation. The vacuum regulator and metering
tube panel are close coupled andmounted onto the Ammonia cylinder
valve as a single assembly. The
ejector can be located whereverp lu m b i n g a n d / o r h y d r a u li c
conditions make it most desirable.
Modular design also makes it easy
and inexpensive to expand or
upgrade the system. The metering
tube panel may be detached fromthe vacuum regulator at any time, injust a few minutes, if future
requirements or safety dictate aremote metering application, or
multiple point chlorination is desired

3. The rate valve "Seat" is pure
fluoroplastic and will not swell, stickor become brittle with age or
exposure to liquid Ammonia.

MATERIALSCONSTRUCTION

One of SUPERIOR’s™' major
competitive advantages is the use ofthe finest, strongest and mostdurable materials available.
Extensive use of Fluoroplastics andfiberglass reinforced thermoplast i c s a llo w SU PE R I OR™
Ammoniators to withstand attack by
Ammonia in any form and to give thelongest operational life. Many parts
are guaranteed for the life of theequipment against Ammonia
damage.

4. All external bolts and nuts are
Titanium for complete corrosion
resistance..a SUPERIOR™ exclusive.
There are no stainless steel ormonel nuts and bolts to corrode andfreeze up in the presence of moist
Ammonia gas.
5. Extra heavy-duty outlet threads onthe ejector diffuser preventsaccidental breakage from overtightening or "bumping" of theejector assembly.
6. The "Universal" ejector diffuser allows use of high pressure
solution hose, direct ejector mounting in mains, or in-line piping withrigid solution pipe.
7. Easier to service and perform routine maintenance, with standard
size wrench lugs provided on all screwed-together ejector parts. No
more pipe wrenches to accidentally tear and scrape plastic surfaces.
8. All vacuum fitting holes are heavily reinforced to prevent thepossibility of cracking from over-tightening fittings.
9. "Dual-pressure" check valve is standard on all SUPERIOR™
Ammoniators. Proven high back-pressure unitized check valve
design protects against sudden surges up to 300 PSIG while a springloaded diaphragm check provides positive shutoff even when there
is no back-pressure to force the seat closed.

OFSYSTEM OPERATION

The vacuum regulator is securely clamped onto the Ammonia cylindervalve. Water under pressure flows through the ejector at high velocity
which causes a strong vacuum to be created. This opens the checkvalves in the ejector assembly and transmits a vacuum signal throughthe meter tube/rate valve panel back to the vacuum regulator. Whenthe vacuum reaches a pre-set level, the diaphragm in the regulator
moves to open the Ammonia inlet safety valve, permitting gas to flowfrom the Ammonia cylinder. The spring-opposed diaphragm and inlet
valve regulate the vacuum at this point.
Ammonia gas passes through the flow meter panel and rate control
valve to the ejector. The gas mixes with the ejector water and isdischarged through the diffuser into the water being treated.
