SMART CONTROLS
plant in operation are uploaded to an app and can be reviewed off site. Reports are then sent to local branch offi ces and shared with customers.
Laser Alignment The compressor and drive motor within an open drive arrangement on a refrigeration plant operate on fl exible couplings. It is essential that these components remain in line both vertically and horizontally during operation. Until recently, specialist companies were brought in by maintenance providers to use expensive and complicated laser alignment equipment to measure and correct any issues.
High tech tools have now been developed which allow the laser alignment process to be undertaken by in-house maintenance engineers. A series of sensors fi xed to the plant relay readings to an app, providing an instant picture and report on coupling alignment. This technology has really taken laser alignment to the next level.
Remote Monitoring Remote monitoring technology provides refrigeration engineers with a phenomenal amount of information and leads to signifi cant cost savings for customers. From 24/7 handling of alarms and alerts, through
to trending data and graphics, remote monitoring technology is a key development in modern tooling. Remote monitoring is conducted online and allows
maintenance engineers to view every aspect of plant operation around the clock. Fault alarms and alerts generate automated emails to engineers, who can dial in to the plant’s control system via smart phone or computer to address the issue through a technical adjustment or reset. This online access to plant controls enables
engineers to deal with a large number of maintenance issues remotely, without the need for a site visit. With 24/7 remote monitoring of alarms and alerts, many engineering issues can be resolved quickly and eff ectively online. This ensures minimal disturbance to customer operations on site and reduces the need for costly call outs. A further level of remote monitoring involves
constant recording of key operational data and performance trends, with expert off site analysis and reporting. Data is reviewed and a remedial task list is created for fi eld engineers to attend to during site visits. Task lists are focused on proactive maintenance activities such as technical adjustments, corrective actions and investigations to improve effi ciency and save running costs. Remote monitoring is becoming central to
minimising downtime and increasing effi ciency as part of an ongoing PPM programme. The service enables end users to achieve the best return on their investment by reducing the whole lifecycle cost of the plant.
Refrigeration customers can now benefi t from the ultimate in remote monitoring technology and asset management as part of a proactive and predictive maintenance programme. A sophisticated software system can be employed to analyse energy usage data, in order to optimise plant performance. This helps operators of large cooling systems to achieve substantial energy savings. Thanks to modern tooling techniques, refrigeration customers are seeing a marked increase in plant reliability and substantial cost savings. Many are reaping the benefi ts of these once specialist techniques being employed in their regular maintenance programmes, with fewer site visits, minimal disturbance and less downtime required. For maintenance providers, modern tooling techniques have improved service delivery in terms of both effi ciency and eff ectiveness, saving engineering time and resources. Technology has advanced to the point that it is highly aff ordable and simple to employ, allowing engineering companies to deliver the next level of service for customers.
