Good quality (dry) steam starts at the
boiler and as it travels through the distribution system, changes in
temperature, pressure and upset conditions related to
feed water treatment and transient loads contribute to generation of condensate.
While steam traps will help remove condensate flowing within the
pipelines, cyclone separators are used to remove condensate droplets entrained in the
steam flow. Properly sized centrifugal steam separators can also
handle "slugs" of liquid being sent downstream due to clogged strainers
and low areas of plumbing.

Why Remove Entrained Condensate?
Dry steam is preferred for direct
contact applications involving steam
powered equipment, cooking and atomization of other liquids because the
liquid itself is damaging to the equipment (corrosion) or process
(contamination). High velocity impact of entrained
water droplets contribute to erosive damage of critical pipeline
components such as pressure reducing valves. Reclamation of treated boiler water reduces the
consumption of boiler treatment chemicals, a
significant cost savings.

Cyclone steam separators employ centrifugal
force, change in direction and reduction in velocity to ensure 99% of
droplets greater than 10 microns do not pass though the separator.
Our cyclone steam separators have no internal moving parts or
serviceable components, it is simply a fully welded pressure vessel.
The cyclonic action with droplets and pipe scale continuously scour the
inside of the separator keeping it clean and thus there is no maintenance required.
The only cost is the initial procurement and installation of the
separator, thereafter they will function reliably and reduce operating
costs for decades.
Re-entrainment of separated condensate is
prevented by a containment plate which prevents agitation of the pooled
condensate by the vortex. Although this is not "universal" to
centrifugal separator designs, the models we offer all have this
Whereas impingement plate style separators have
a turndown limit, our centrifugal steam separators have an infinite turn
down ratio. This aspect is critical during start-up and shut down
phases of a steam system.
steam separators are designed to handle horizontal and vertical flow paths
as well as combinations thereof and our standard materials include cast iron,
carbon steel and stainless steel. We offer other alloys of
construction which are commonplace at chemical plants and refineries.
Exhaust heads are a special type of cyclone separator installed at
the end of a vent pipe to reduce the opacity and carry-out of vapor
contaminated with boiler treatment chemicals. This treated boiler
water can be reclaimed and
reused, reducing chemical consumption. Unlike separators, exhaust heads
are not pressure vessels because the outlet is always open to
Use our sizing tool above to determine the appropriate separator
size for your application. Remember that
it is typical to attach smaller size connections to mate with
your existing piping but you should never use a separator element size smaller
than your existing pipeline; do not reduce the pipeline to install a
