CHOOSING THE IDEAL DISPLAY FRIDGE FOR A RETAIL BUSINESS
A commercial display fridge helps to position merchandise for maximum exposure , ensuring that a supermarket ’ s customers know exactly where to find what they need . Perhaps a retailer may even want to use them near a ‘ temptation aisle ’ to help upsell drinks and food while customers are walking to the check-out . Just Refrigeration explains what to look for in a good display fridge . There are many sizes and shapes to choose from .
“ What are you planning to store in your display fridges ? This is the most important question you should ask yourself as you make your selection . Display fridges are generally designed to carry a certain type of stock and appeal to a certain customer in a specific setting . Perhaps you need an upright display fridge , for example , a tall fridge used in a variety of contexts , from supermarkets and grocers to take-out restaurants .
“ If you are selling frozen goods , such as ice cream , ready-made meals or frozen vegetables , then you also need an upright display – a freezer in this case . There are also specialised fridges such as cake fridges , bar fridges and flower fridges .
“ Once you know what your fridge ’ s contents are going to be , consider the size and location of fridges . Whatever fridge you buy , you should also make energy efficiency an important criterion in your decision making .”

SUPERMARKET EQUIPMENT SECTOR ADAPTS TO ENERGY EFFICIENCY AND ENVIRONMENTAL FRIENDLINESS
Mark Howitt , group sales director : HC Group , says HC Group is at the forefront of pioneering projects in local CO 2 technology , with plans to develop a CO 2 air handling unit — a first in South Africa , they claim . This initiative underscores the company ' s response to growing demand for eco-friendly refrigeration solutions in the supermarket sector . By leveraging
CO 2 technology , HC Group aims to set new standards for energy efficiency and environmental stewardship .
“ Though market trends in refrigeration equipment have seen minimal changes over the past decade , HC Group subsidiary RRC ( Refrigerated Retail Cabinets ) differentiates itself through adherence to European standards and robust design tailored for the African market . Unlike European suppliers whose products may prioritise aesthetics over durability , we rather prioritise functionality and resilience to withstand the rigours of African conditions . Additionally , our efficient assembly process and extensive stock availability contribute to shorter lead times , providing customers with swift and reliable service , enabling the group to facilitate tailoring their refrigeration solutions to specific needs and preferences ,” he adds .
RRC adopts a collaborative approach to manufacturing , sourcing standard cases from Europe and customising them to

The context for HC Group ’ s innovation drive is a supermarket refrigeration equipment sector facing increasing pressure to prioritise energy efficiency and environmentally friendly refrigeration and cooling equipment .
Another trend Howitt points to is the widespread transition from simplex refrigeration systems to more efficient multiplex systems . While this shift has been ongoing for years , it remains the central strategy for enhancing energy efficiency in supermarket operations . However , challenges persist in outlying areas , where technical expertise and availability of components may limit the adoption of advanced systems .
There is a heavy reliance on local manufacturers for equipment and components in South Africa . While CO 2 technology has gained traction domestically , challenges persist in ensuring consistent supply and accessibility of parts .
“ Efforts to enhance energy efficiency extend beyond refrigeration systems to include innovations such as cabinet doors . The widespread adoption of glass or acrylic doors in supermarkets reflects a collective

Transitioning to advanced refrigeration systems like CO 2 poses technical challenges , particularly in terms of maintenance and skill requirements . While multiplex systems offer greater efficiency , they also demand a deeper understanding of controls and operation . Overcoming these challenges requires ongoing training and education for maintenance personnel to ensure the seamless integration and optimal performance of new equipment , explains Howitt . There has traditionally been a psychological barrier associated with installing doors on refrigeration units . “ While there is a convenience in open display cases , the energy-saving benefits of enclosed units is trumping convenience . By preventing temperature fluctuations and minimising energy loss , refrigeration units with doors offer substantial efficiency gains , with potential energy savings ranging from 40 % to 50 %. Additionally , the longer shelf life of perishable goods stored in enclosed units contributes to reduced wastage , a significant consideration for retailers ,” says Howitt .
