• Data represents scaled stresses not fatigue life, as FOS is based upon Factor of safety for all failure modes and yield

The above image depict stress concentrations
on a common generic type nozzle in use. Red
shaded areas show around 8 times allowable stress.
Click&Dry™ below depicts stress concentrations
well within the allowable stress of the material.
The Click&Dry™ design makes safety and pressure integrity its number one design priority. Since the early 1970's, high volume
powder production has seen the emergence of nozzle type driers as a major developing trend, resulting in steadily increasing
operating pressures to achieve the volumes and consistencies required. This placed enormous demand upon pre-existing
nozzle hardware designs, which over time has essentially remained unchanged. Today, it is not readily shown that this hardware
is operable without significant risk and within accepted safety factors now dictated by modern industry.
Spray Nozzle Engineering has studied many types of drier nozzle hardware in use today. The initial findings of this study were
that a generic form of nozzle design has been in common use for some considerable time, from a number of different sources,
with most utilising radial seals and very similar hardware geometry. It was also determined through analysis in this study, that
a large proportion of such equipment reviewed may operate far in excess of industry accepted stress and pressure limits due
to this observed generic geometry and radial seal arrangements. Further, that much of this hardware exists in a worn or old
and fatigued condition, which alone, poses a high risk of failure. Click&Dry™ was developed to function within a range
of operational safety factors which far exceed that of current competitive equipment in the field, with unique high
pressure axial seals, as well as a design that resists the normal types of observed wear characteristics of older style
nozzles in service.
Industries working with pressure systems and vessels, typically stipulate a safety factor of 2-2.5 times based upon the yield stress
of the material in use. If operating at a safety factor below 2, a thorough understanding of your fatigue cycles and the potential
failure risk is critical. Operating at safety factors approaching 1 or below, ensures failure is imminent based upon known
engineering protocol and the properties of typical materials used. This is why Click&Dry™ components are designed around
important pressure related standards such as ASME B31.3. These standards are dedicated to safe operation of pressure
systems and provide safety margins that exceed those in current use based upon the yield stress and other important factors.
World Wide Sealing standards all dictate the use of backup rings in the typical radial seal arrangements found in most
common drier nozzles. Widely adopted global standards typically call for pressure limits of around 100barG without backup
rings. One exception is JIS B2406 seal standard which still limits the working pressure without backup rings to only 255barG,
this only being achievable with enormously tight radial gap and costly higher duro-rated O-rings. It is clear most modern driers
operate far in excess of these pressures and as such require a more reliable and compliant sealing option. Click&Dry™ axial
seal arrangement allows for greater operating pressures with no need for expensive backup rings and high duro-seals. This
is good news for drier operators in managing operating costs of daily seal replacement.
It can be seen from the review summary below, that many common older spray components in use today operate at pressures
far exceeding their yield stress, with a risk of failure, being extremely high. Operating this older equipment at this level is not
recommended. This review chart provides the customer with a range of notional safety factors to help them identify the level of
operational risk they currently choose to adopt.

Compliance
Did you know that spray dry nozzles
are required to comply to pressure
piping codes such as ASME B31.1 and
international O-ring sealing codes,
that will limit many older nozzle
systems still in use. Your nozzle may
be operating in excess of those limits.
The Click&Dry™ Hi-Flo Mini nozzle
was the first spray dry nozzle to
introduce high strength caps 'No-
Gap axial seal' technology - the
true compressive seal that does not
require backing rings and can be
used on high and low pressure dryers
alike.
Concentricity Clasp
Technology
With CCT, parts are always located
correctly every time, and with our
unique clasp system, your precious
wear parts can be aligned for
ultimate spray performance.
With EasyOut clasp, wear parts are
also removed easily without the need
for impact force removal, leading to
carbide breakage as seen on some
systems in use.
Cleanability
The Push-Fit Concentric Clasp
Technology using Seal-In-Disc™
wear parts, gives stronger lower
profile caps that have a smoother
internal finish without internal cap
O-ring grooves. This increases
hygiene and reduce change-out and
cleaning times.
Cross thread resistance
Our thread gall resitant materials
and heavy duty protected female
threaded lance fittings, which are
highly resistant to normal impact
damage during lance handling. This
improved design also extends both
body and cap life.
Check Valve Drip-Pro™
Heavy duty Check Valve reduces the
problem of dripping and scorched
particles. Replaceable seals not only
allows a number of sealing options
but its new high flow design runs
longer than previous designs and
is easily removed for cleaning. This
'open-port' design can be run on all
drier types.
Cap performance
With two standard cap profiles to
reduce product build up and with our
improved internal hygiene design,
there is a nozzle to suit every dryer
type.
