Refrigeration is vital to the survival, safety and continued operation of businesses. More often than not, refrigeration is neglected and relegated to the bottom of the list of priorities, until things start to fail. However, things do go wrong and It's important to keep on top of regular maintenance to guarantee safety, low operating costs, reliability, efficiency, and plant longevity. To put things into perspective, typically, 60% of a system's total life cycle costs are accounted for by its operation, while maintenance accounts for 20%. Capital investment represents only a marginal value of the refrigeration system's total life cycle costs at 15-20%. This seminar looks at the reasons why maintenance should be taken into account to ensure the solidity of business operations.

It is easier than ever to collect data and our mountain of data is growing rapidly. However, if it isn’t looked at, understood and actioned then it isn’t providing any value. How then do we use this data to our advantage? Computer modelling to create a ‘digital twin’ can answer this question by looking at the load on the plant, the efficiency with which it is dealing with the load and what system components are underperforming. The result of which informs decisions and leads to prompt, targeted action. This presentation will provide an analysis on how data is captured, processed and what results can be achieved.

Spares have an essential role in industrial refrigeration plant aftercare. When a component breaks or a fault develops, it is vital that replacement parts are sourced and fitted as soon as possible, to minimise downtime and disruption. A highly responsive and reliable Spares service helps refrigeration engineers get equipment back up and running quickly following a fault or breakdown. This fast response can potentially save plant operators thousands of pounds in costly downtime. In this article, Calum Mckenzie explains the critical role of spares in industrial refrigeration plant aftercare and what an effective spares service should look like.

The price of electricity in the UK today is roughly double what it was a decade ago. There is also greater volatility in the pricing market, making future expenditure more difficult to calculate. Given that paying for energy typically consumes between 9% and 17% of a cold store facility’s revenue, and that the refrigeration system often comprises upwards of 70% of those costs, it makes sense to mitigate spending as much as possible by optimising energy use. Dr Rob Lamb explains how Specific Energy Consumption as a predictive metric for business performance in the TCS&D sector The Internet of Things and The Evolution of Refrigeration Plant Aftercare.

Whether a facility is a stand-alone cold storage unit or part of a larger site with production processes, it is entirely normal that all heat from the refrigeration plant is discharged to the atmosphere. However, what if we decided to capture the waste heat and use it? What techniques are available and what options present themselves to harness this assumed valueless waste heat? With around 50% of gas consumption in the UK being for heating buildings opportunities for the economic harnessing of cold storage (or process) waste heat are only going to get better. This presentation will support anyone with any aspirations to harness waste heat.
