Star Refrigeration had developed a good relationship with the company over the past ten years, and gained a good reputation for the design and maintenance work carried out at other sites across the country. This led to the customer taking out a three-year maintenance contract with Star Refrigeration Operations Group's.
When Star engineers arrived on site, they found that the customer’s ammonia plant was overcharged with oil due to incorrect setup. Soon after taking over the contract, the plant’s expansion valves were replaced in order to regulate gas back to normal working pressures and levels while ensuring Star's maintenance routines had no impact on the customer's normal operations.
An important part of Star Refrigeration’s aftercare work was to bring the British pharmaceutical company’s ammonia plant up to date with current regulations as well as the implementation of SAP procedures to the air conditioning systems were routinely assessed and subject to regular and consistent maintenance.
As part of Star's proactive maintenance plan, the plant performance was reviewed on a frequent basis. Working closely with the customer’s energy supervisor, Star monitored the plant's energy usage. After identifying when the plant was not operating at maximum efficiency, Star introduced measures to minimise energy waste such as the installation of timers in all air conditioners at the site’s central offices, which reduced the customer’s energy bill by £8000 per annum.
Star’s good performance during the initial contract period resulted in the customer renewing their aftercare contract for another three years. In addition, Star's Aberdeen team was entrusted with a new project which involved the design and installation of a brand new refrigeration plant for an extension to their facilities.
Star Refrigeration Operations Group offers 24-hour technical support for the customer from nine branches across the UK. This includes design, maintenance, service, contracting and spare-parts.
