Engineers cut Heinz steam costs

A Spirax Sarco product story
Edited by the Engineeringtalk editorial team Mar 2, 2007

Spirax Sarco engineers were on site at Heinz' factor in Wigan for 10 days, surveying 559 traps, of which 75 were found to need maintenance to improve their energy efficiency.

Energy savings have enabled Heinz to realise a payback of less than nine months after investing in a Spirax Sarco steam trap survey and undertaking the resulting remedial work.

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 continental European market, and its on-site energy centre generates up to 140 tonnes of steam per hour to keep the canning lines running.

The site has more than 550 steam traps, but there hadn't been a systematic trap survey for over five years.

"We decided to have a full survey in light of our commitment to energy efficiencies and improvements", says the site's environmental compliance manager.

"We decided to buy in the necessary steam system expertise by calling in Spirax Sarco".

The Spirax Sarco engineers were on site for 10 days.

They surveyed 559 traps, of which 75 were found to need maintenance to improve their energy efficiency.

The subsequent remedial work was undertaken in-house by Heinz maintenance teams.

According to the environmental compliance manager, Heinz intends to prevent possible future losses by adopting a planned approach to steam trap maintenance, including bringing in Spirax Sarco to carry out annual surveys from now on.
