Heinz will slice more than 4% from its energy consumption in the next three years at its Wigan factory after signing up for a steam trap management contract with Spirax Sarco. The decision to opt for the new contract followed great success with a previous, one-off steam trap survey, which saved enough energy and treated water to pay for itself in less than nine months.
The Heinz factory in Wigan is the largest food factory in Europe. The 55-acre site produces canned soups, baked beans, pasta and puddings for the UK and European market, and its on-site energy centre generates up to 140 tonnes of steam per hour to keep the canning lines running.
Under the new deal, Spirax Sarco engineers will survey the site every six months, highlighting any traps that need maintenance from teams at Heinz. Spirax Sarco specialists will spend around 10 days on site each year, checking, tagging and recording the condition of each steam trap.
“When Spirax Sarco carried out the original survey they put in a conservative estimate of savings and we ended up saving much more,” says Barry Aspey, the Utilities Manager for Heinz. “That helped us decide to opt for the three-year contract. If the new savings estimates are correct, the contract offers excellent value for money and should help us reduce our carbon emissions by 200 tonnes a year.”
