Star boosts capacity at Blackburn Brewery.<\/p>\n

Star Refrigeration has recently completed a project\u00a0to boost capacity and reduce energy costs for\u00a0Blackburn based brewer, Daniel Thwaites.<\/p>\n

Following previous successful projects replacing\u00a0heat exchangers and separator vessels, Star\u00a0replaced an existing reciprocating compressor and\u00a0added additional plate heat exchanger cassettes to\u00a0a modular cooling plant. This increased capacity\u00a0from 310kW to 400k and reduced weekly running\u00a0costs. This nett effect is a return on investment of\u00a0less than 18 months.<\/p>\n

This improvement in efficiency comes from a\u00a0combination of using an inverter controlled\u00a0reciprocating compressor in place of the original\u00a0fixed speed machine and installation on a new\u00a0compressor sequencing system.<\/p>\n

A comparison of fixed speed and variable speed\u00a0replacement options at the tender stage\u00a0demonstrated the benefits of using a variable frequency drive (see graph 1). Daniel Thwaites recognised the operating cost benefits from investing in the variable speed option and these have been realised on site following successful plant installation and comparison.<\/p>\n

Further enhancement of performance has been\u00a0achieved through the installation of a new\u00a0compressor sequencing controller. This measures\u00a0the secondary IMS cooling medium temperature\u00a0and sequences starting\/stopping of the new inverter\u00a0driven compressor and two existing fixed speed\u00a0machines.<\/p>\n

Power measure on site demonstrates average\u00a0weekly savings of around \u00a32,000 on site electricity\u00a0costs (see graph 2) following installation of the new\u00a0compressor and sequencer. This results in a\u00a0payback of less than 18 months based on current\u00a0energy cost.<\/p>\n

“The replacement of our ammonia compressor had\u00a0the potential to cause issues with production from\u00a0both a temperature and logistics perspective. The\u00a0thorough and detailed project management carried\u00a0out by Star meant that neither of these became and\u00a0issue. Star\u2019s attention to detail continued through\u00a0the commissioning stage, right up to running in of\u00a0the unit during the initial 3 months. Customer\u00a0queries were dealt with quickly and advice on\u00a0efficient operation has been essential to reducing\u00a0our electricity costs, which have been greater than\u00a0anticipated,” – Thwaites Projects and Utilities\u00a0Manager, Mick Cockshott.<\/p>\n

The Daniel Thwaites installation is just one example\u00a0of energy enhancing solutions from Star\u00a0Refrigeration. Others include:<\/p>\n
