Steam traps cut energy costs in rubber production
A
GEM product story

Instead of using a valve mechanism to close off steam for maximum energy and water conservation, GEM steam traps use the venturi orifice design to effectively drain condensate from the steam system.
Ruabon Works, a specialist chemicals manufacturing site operated by Flexsys Rubber Chemicals, is making steam savings of 12% from its batch reactor following the installation of Gardner Energy Management's GEM Venturi Orifice steam traps.
The company has installed GEM steam traps on a condensate recovery project and is now fitting GEM traps across the site.
As part of a steam optimisation project on one of its process plants, Flexsys Rubber Chemicals decided to review its condensate trapping system associated with the internal coils of a batch reactor, using 10% of the site's steam demand.
The company was dissatisfied with the three existing ball float traps, which at GBP1200 each were costly to install, required replacing every two years and were prone to corrosion.
In addition, without regular routine monitoring, the company was not always able to identify when the traps were faulty.
After a review of the project with Gardner Energy Management, Flexsys Management decided to replace all three traps with GEM Venturi Orifice steam traps.
Following the successful commissioning of the reactor, Flexsys decided to replace five ball float traps on a condensate recover project, this time associated with heater banks on a fluid bed drier system with GEM traps.
"Once again, the GEM traps made a significant contribution to the success of this project", said Richard Collier, Senior Process Engineer as Flexsys Rubber Chemicals.
"So much so, that Flexsys is now installing a series of energy saving projects across the site which will replace inverted bucket type traps with GEM steam traps".
Instead of using a valve mechanism to close off steam for maximum energy and water conservation, GEM steam traps use the venturi orifice design to effectively drain condensate from the steam system.
As the GEM steam traps have no moving parts to wedge open or fail, they provide very high reliability, necessitating minimal maintenance and requiring no spares, testing or monitoring equipment.
"The Venturi Orifice design of GEM steam traps means that there are no moving parts to fail", Collier said.
"The only maintenance we now carry out with the GEM traps is to regularly check the strainers upstream".
Available in a wide range of sizes for a full cross section of applications, the hardwearing GEM steam traps are manufactured from corrosion-resistant stainless steel and are guaranteed for 10 years, obviating the need for repair or replacement.
