The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.
Built-in spacers to ensure good ventilation
Spacer strength to support and protect the heat exchanger
Recessed/covered heat exchange radiator/cooling panel
Examine the rear structure of machine to look for spacers and to see if the heat exchange radiator looks well made and without any signs of weakness.
Ask for clear evidence of meeting the requirements listed above to be provided, e.g.:
Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.
To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).
Small plastic spacers, or larger strips, can be injection moulded into the fridge. These will reduce chance of damage to the heat exchanger and ensure increased airflow, putting less load on the compressor.
Simple inspection procedures will help to identify manufacturing faults and component issues, reduce failure rates and customer returns.
Stronger spacer strips or recessed cooling radiator
For the heat exchange radiator to be effectively recessed in the back of the unit a significant change to the fridge freezer case or the addition of long strip mouldings either side is needed.
This change will help to reduce the occurrence of damage to the cooling circuit components. Modern units often have the recessed heat exchange radiator covered with a steel plate to achieve this.
