Syphons remove liquid from drying systems after heat transfer has occurred and condensate has formed.

Syphon selection is an important factor in maximizing the drying rate and minimizing cross-machine temperature variation of dryers. Rotary syphons rotate with the dryer and are used in lower speed applications where condensate is pooling, while stationary syphons remain in a fixed position and are used in higher speed applications where condensate is rimming. Our portfolio of syphons are tailored to the machine speed, steam pressure, condensing loads, blow-through steam characteristics, and other parameters of different applications.

If there were only one kind of rotating cylinder and only one set of operating conditions, choosing the right syphon system would be a simple matter. But that’s not the case. In order to end up with the most effective syphon system, a great deal of care must be taken to ensure an efficient and reliable syphon system is selected. Operating conditions such as machine speed, steam pressure, condensing loads, blow-through steam, and other parameters all have an effect on syphon selection.

Pivot Body Syphon Elbow

Pivot Body Syphon Elbow

The Pivot Body syphon elbow allows a syphon pipe to be inserted into a dryer through the dryer journal, without the need for a hand hole or manhole. Unlike conventional syphon elbows, the Pivot Body syphon elbow does not rely on a hinge pin to hold vertical and horizontal bodies together.

Spring-Lock Syphon Elbow

Spring-Lock Syphon Elbow

The Spring-Lock syphon elbow uses a conventional gravity-lock elbow reinforced with collars, braces, and a heavy-duty spring. The spring-lock system is a relatively low-cost upgrade to conventional gravity-lock elbows, reducing susceptibility to failure, and allowing higher speed operation.

45° Locking Syphon Elbow

45° Locking Syphon Elbow

The 45° Locking syphon elbow is designed for high-speed, small roll diameter applications. The stainless steel horizontal body is secured to the vertical leg using a proprietary locking mechanism. This elbow has four parts including a body, swing body, locking screw, and spring. All components are made of stainless steel.

Internal Supported Stationary Syphon

Internal Supported Stationary Syphon

The Internally Supported Stationary Syphon (ISSS™ syphon) is a cantilevered stationary syphon supported by an internal carbon bushing. The ISSS is suited for small-bore journal paper dryers and open-gear machines operating at medium to high speeds This syphon system is used with the ELS steam joint.

Cantilever Stationary Syphon

Cantilever Stationary Syphon

The Cantilever Stationary syphon is designed for use on paper machine dryers running up to 2,000 mpm. The robust syphon is engineered to integrate with the dryer drainage system and system components. This syphon design is used with the PT2X steam joint.

Rotary Scoop Syphon

Rotary Scoop Syphon

The Rotary Scoop syphon is designed for non-rimming cylinders with access to inside the dryer via a manhole. The scoop syphon operates by accumulating condensate during its travel through the puddle near the bottom of the dryer. As rotation continues, the scoop mechanically lifts the condensate to the center pipe and discharges it out of the dryer, through the horizontal pipe.

Rotocurve Syphon

Rotocurve Syphon

The Rotocurve syphon is designed for small diameter dryers that do not have access inside the dryer via a hand hole or manhole. It is installed from outside the dryer via the journal bore. The most common applications for the Rotocurve syphon are open gear paper machines operating at slow to moderate speeds.

Conventional Rotary Syphon

Conventional Rotary Syphon

The Conventional Rotary syphon is used for rimming applications below 1,000 mpm. The rotating syphon uses a heavy-duty spring to securely hold itself in place against the cylinder shell and a stainless-steel pickup foot is welded to the vertical condensate pipe. The close-clearance design minimizes rimming condensate inside the dryer.
