Refrigeration System Upgrade Case Study 1

Inefficient refrigeration systems cost time and money, negatively affecting the business bottom line. In fact, after wages, electricity costs are many businesses largest expense, so it makes sense to ensure that your refrigeration system is operating as efficiently as possible.

A small Hunter based supermarket faced a challenge. Their shop was hot and noisy, breakdowns were frequent, and their energy usage was high. Mercury engineers recommended remote VSD driven refrigeration systems to replace existing equipment. Over the course of a multi-stage, multi-year project, we were able to deliver our client reliable, quiet, energy efficient systems that will pay for itself over time. The client’s trade was not impacted during work. We are pleased to hear that the client now reports increased revenue on top of a 20% reduction in power usage.


This open stlye self-contained display fridge was noisy, unattractive and ineffecient. Heat was being added to the shop, causing excessive operation of the air conditioning system. Strip curtains were installed by the client in a attempt to keep his produce cool. Shoppers were affected by excessive operating noise of built in compressors.

Mercury installed an enclosed style remote display fridge that was quiet, elegant and effecient. VSD operation means that this installation will pay for itself within 3 years in electricity usage savings. An added bonus for the client is that revenue has increased and spoilage losses are dramatically reduced.

Refrigeration System Upgrade Case Study 2

Outdated refrigeration systems are inefficient and costly to operate. Often multiple systems are required to cool products in large venues, resulting in large running costs. It can be beneficial to replace these outdated systems with modern, load sensing refrigeration systems that can vary their capacity according to load demand.

A Hunter entertainment venue had aged and unreliable glycol systems that experienced high beer demand during functions and low demand at other times. Maintenance and operating costs were high, and the systems were noisy. Mercury engineers recommended twin VSD driven refrigeration systems to replace four existing refrigeration compressors to reduce space requirements and installation costs.

Mercury was able to deliver our client reliable, quiet, energy efficient systems that consume less energy that the original installation and will pay for themselves over time. VSD driven compressors mean that not only are these systems efficient to run, but they are also better suited to varying capacity demands of the venue. Replacement was scheduled outside of peak periods, ensuring the client’s trade was not impacted during the upgrade works. The client can now expect up to a 20% reduction in power usage when compared to the original systems.


The installation at this entertainment venue had four refrigeration condensing units cooling beer systems. These compressors were noisy and ineffecient, adding to large operating and maintenance costs.

Refrigeration Maintenance Programs

The Importance of Refrigeration Maintenance: Keeping Your System Cool and Efficient

Refrigeration systems are crucial for a wide range of industries and everyday life. From preserving food and medications to maintaining optimal conditions in various commercial and industrial settings, refrigeration plays a vital role in modern society. To ensure the smooth operation and longevity of refrigeration systems, regular maintenance is essential.

Efficiency is a key aspect of any refrigeration system. Regular maintenance helps optimize efficiency, reducing energy consumption and operating costs. Over time, dust, dirt, and debris can accumulate on coils and condensers, inhibiting heat exchange and forcing the system to work harder to maintain the desired temperature. Routine cleaning and inspection of these components can ensure optimal airflow and heat transfer, enhancing the overall efficiency of the system.

Proper maintenance significantly extends the lifespan of refrigeration systems. By addressing minor issues promptly, you can prevent them from escalating into major problems that could lead to system failure. Regularly inspecting and replacing worn-out components, such as belts, filters, and seals, helps maintain the system’s integrity and prevents costly breakdowns. Additionally, lubricating moving parts and checking refrigerant levels ensures smooth operation and prevents excessive wear and tear.

Refrigeration system failures can result in significant financial losses, especially in industries where temperature control is critical, such as food service and pharmaceuticals. Preventive maintenance reduces the risk of unexpected breakdowns by identifying and addressing potential issues early on. Technicians can identify worn-out components, refrigerant leaks, or electrical problems before they lead to system failure. Implementing a regular maintenance schedule not only prevents costly downtime but also saves on emergency repair expenses.

In the food industry, maintaining proper refrigeration is crucial to ensure food safety and prevent spoilage. Regular maintenance helps uphold consistent temperatures and proper humidity levels, preserving the quality and freshness of perishable items. Properly calibrated temperature controls and timely maintenance of refrigeration units minimize the risk of bacterial growth, preventing foodborne illnesses and maintaining compliance with health and safety regulations.

Refrigeration systems that are not well-maintained can be harmful to the environment. Leaking refrigerants, such as chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), contribute to ozone depletion and global warming. Routine maintenance includes checking for leaks, repairing them promptly, and ensuring proper refrigerant management. By minimizing refrigerant leaks and optimizing system efficiency, you can reduce your carbon footprint and contribute to environmental sustainability.

Regular maintenance is vital for the efficient and reliable operation of refrigeration systems. By maximizing efficiency, extending the system’s lifespan, preventing costly breakdowns, ensuring food safety, and promoting environmental sustainability, you can reap the benefits of a well-maintained refrigeration system. With proper maintenance, your refrigeration system will continue to provide optimal performance, saving you money, preserving valuable resources, and ensuring the safety of your goods and products.

We understand that refrigeration system breakdowns are not just inconvenient, they can directly affect the business bottom line. Repair costs are not the only considerations when commercial refrigeration systems fail. Additional points to consider when deciding on a maintenance program include:

  • Loss of stock
  • Loss of trade
  • Loss of reputation
  • Increased insurance premiums

Proactive maintenance programs are designed to reduce breakdowns and optimize system performance. Regular commercial refrigeration system inspections can identify and monitor minor system faults before breakdowns occur. Corrective action can then be taken or budgeted for at your convenience. For commercial clients we recommend bi annual (pre-summer and pre-winter) refrigeration inspections to minimise breakdows and running costs. Keep your commercial refrigeration system operating at its peak performance with a preventative maintenance program by Newcastle’s leading refrigeration technicians.
