One year after upgrading its steam traps with up-to-date equipment from Spirax Sarco, Marston's Brewery is reporting savings of £60,000 in energy and hot water costs.
 By preventing steam escaping into the in Burton on Trent brewery's condensate recovery systems, the new steam traps have also improved the site's environmental image by eliminating visible steam emissions.
"You used to see plumes of steam exiting the plant, but now that's all stopped," states Colin Walton, senior engineer at Marston's Brewery. And he adds that the change was instant, with the quantity of escaping steam clearly reducing as more of the steam traps were replaced.
"I used to tell the fitters that I'd know they'd done their job when steam stopped coming out of the condensate tank in each section," quips Walton.
Spirax replaced some 70 old steam traps with its stainless steel sealed inverted bucket steam traps. Says Walton: "Price and quality were the deciding factors in choosing Spirax Sarco, but they also delivered great local support."
Walton also explains that Marston's took the opportunity to remove trap bypasses – often installed to enable engineers to redirect condensate around defective traps – from the steam system at the same time. In his view, they encourage bad practice by enabling the steam system to carry on operating at a suboptimal level, rather than forcing engineers to fix defects fast.
