SUPER STEAM VAC

Maximizing the MD dryness gain and CD moisture profile improvement from a Fourdrinier while eliminating the couch vacuum which cools the sheet before the press section.

  • 1,2 or 3 chambers
  • Last chamber to operate at 18-22 " Hg
  • No seal leg vacuum limitations
  • Silicon Nitride or SI-CARBIDE EXTREME cover
  • Transphase Z-Box Steam Profiler custom designed to Match vacuum box and cover

Benefits:

  • Sheet solids greatly improved
  • CD bump response + or - 2.5% or greater
  • 6% or greater speed increase
  • Reduction or elimination of Couch vacuum

FOURDRINIER– Z BOX STEAM PROFILER

The Patented Transphase Z-Box Steam Profiler is mounted close to the sheet and delivers multiple machine direction steam jets to the sheet each followed by a converging zone which forces the steam into convergence with the sheet, maximizing the exposure of the sheet to the steam while minimizing the ability for the steam to spread in the CD. The converging zones constrain the steam flow into intense narrow CD zones to provide greater CD moisture control than conventional steam boxes.


COUCH Z-BOX STEAM PROFILER

The multiple Z Plates mounted in the machine direction allows for custom design of the steam delivery to the moving web.

This application produces excellent results for machines making heavy basis weights which do not operate with lumpbreakers and at a speed greater than 1600 fpm.

  • Typical steam use of 0.1 to 0.12 tons/ton.
  • Increase dryness of  1.5 to 2 % into dryers
  • Up to 80 % reduction in 2 sigma CD Moisture

Press Z-Box Steam Profiler

The Transphase Press Z-Box Steam Profiler is custom designed to fit the space available in the press section. Best results are obtained when installed against a suction roll or box.

The Z Plates help to keep the steam jets clean while forcing the steam into convergence with the sheet, maximizing the exposure of the sheet to the steam while minimizing the ability for the steam to spread in the CD. The converging zones constrain the steam flow into intense narrow CD zones to provide greater CD moisture control than conventional steam boxes. 

  • Typical steam use of 0.07 to 0.12 tons/ton
  • Increased sheet dryness increase of 1.5 to 3 %
  • Up to 80% reduction in 2 sigma CD Moisture

ACTUATOR REPLACEMENTS

The CR-2 pneumatic actuator is designed for the toughest of steam box applications. The interior components are constructed from Inconel 600 or higher while the exterior is 316L stainless steel.

" Actuators are working well. Moisture profile is much better and spreads are lower. This was money well spent"  - PMS, Southeast USA

FELT HEATERS

Transphase Technology introduces its advanced Felt Preheater design that offers improvements over current industry designs. The Felt Heater will increase felt temperatures leading to improved cleaning and dewatering of press felts and press screens.


INTERFACE SOLUTIONS

Transphase Technology is pleased to work with all QCS and DCS vendors to integrate our steam box solutions into their control systems. However, if for some reason this is not possible, we have the ability to offer simple remote control panels, direct I/P panels and advanced Festo multiplexing systems with air leak detection.
