The SX rotary joint incorporates two internal carbon-graphite bearings that permit self-alignment and long operating life – even on cylinders that are not concentric. Using new sealing technologies, the SX rotary joint has extended seal life and increased reliability along with application flexibility.

The SX rotary joint line is available in sizes from 3/4” to 3” and can be used in single- or dual-flow applications. The joint is rated up to 650°F (343°C), 300 psig (20 bar), and 550 rpm.

Syphons remove condensate from steam heated rolls.

The selection of syphons plays a crucial role in optimizing condensate removal inside a pressure vessel. Rotary syphons, which rotate with the dryer, are utilized in lower-speed applications where condensate pooling occurs. Conversely, stationary syphons maintain a fixed position and are employed in higher-speed applications where condensate is rimming. Our portfolio of syphons is specifically designed to accommodate various machine speeds, steam pressures, condensing loads, blow-through steam characteristics, and other application-specific parameters.

We combine controls and steam management expertise with a portfolio of steam joints, syphons, and steam handling hardware to deliver high performance. Our control systems automatically and continuously adjust steam set points to create stable and efficient processes. They consider multiple operating conditions including product grade, weight, type, speed, and moisture content. Our control system logic includes anti-flooding, thermocompressor anti-choke, differential pressure management, start-up/shut-down assistance, and process interruption intelligence. During system events, it allows the operator to adjust heat loads while keeping the system in balance. It also monitors energy efficiency and performance of the process allowing for system optimization and preventive maintenance.

Our steam systems and controls technology can be applied to industrial processes that use steam heat in a continuous process. The integration of steam system design including hardware, piping design, and controls give operators the process control and system integration needed to maximize quality and output. A properly designed and efficient steam system can increase response time to system upsets and production changes as well as increase uptime with proper start-up and shutdown procedures. Examples of applications that use steam heat in continuous processes are drum flaking, wet milling, and solutions mining. Industry examples include food, chemical, pharmaceutical, and oil and gas.

Steam from the boiler enters a process section. A portion of the steam condenses, releasing its latent heat. As the steam and condensate exit the process section, they are at a lower pressure. The condensate is separated from the blow-through steam and returned to the boiler. A thermocompressor then recovers the blow-through steam and mixes it with higher pressure motive steam to return it to the supply header.

This maximizes energy efficiency by retaining the energy in low-pressure steam while increasing its pressure by mixing in high-pressure steam. With just three basic components: a nozzle, mixing section, and diffuser; a thermocompressor is simple, yet highly energy efficient.

Recirculating applications capture blow-through steam and recycle it back into the process with a minimal pressure boost. Booster applications increase the pressure of the steam for increased drying capacity.

Thermocompressors are an integral part of maximizing the efficiency of steam systems. It is important to understand the associated syphon characteristics and drying constraints of each application. We offer product and system knowledge as well as field service support to choose the right thermocompressor across multiple applications.

The ThermoZone condensate handling station enables near zero steam pressure in the hot plate section. The lower hot plate pressure and temperature helps bond single face board to the liner without warping for flatter lightweight board. The optional rapid temperature response package includes steam system controls and rapid relief valves that can quickly lower hot plate pressures and temperatures for grade changeovers.

The ThermoZone condensate handling station is designed to operate in the corrugator environment with heavy-duty panels, valves, controls, and radar level sensing. It eliminates problematic steam traps. Performance monitoring and alerts give visibility to system issues before they become board defects. Performance, trends, and alarms are continuously displayed, and the system can be integrated into the in-plant network for remote monitoring and control. Our experts can manage the installation and integration of the Thermozone condensate handling station into the double backer so corrugated packaging plant personnel can focus their resources elsewhere.

Typical installations will include the rapid temperature response package, systems engineering, and installation including electrical and piping. Our experts will ensure the ThermoZone station is fully integrated into the plant controls and steam and condensate system.

The patented design induces turbulence in the rimming layer of condensate for increased heat transfer, and the axial configuration delivers uniform drying across the machine.
