Plug-In vs Remote Refrigeration
…Which Is Right for Your Store?
Not all supermarkets are built the same and neither are their refrigeration needs. The decision between remote and plug-in systems can shape your operating costs, store layout and future sustainability strategy.
Both options have clear advantages, but the right choice depends on your store size, energy goals and maintenance expectations.
Plug-In Systems: Flexibility and Fast
Plug-in cabinets are self-contained units that include compressors and condensers within the case. They’re quicker to install, require minimal pipework and are easy to relocate (this doesn’t mean you can move it around your store on a daily basis!).
They’re ideal for:
- Small format stores and convenience outlets
- Pop-up or seasonal displays
- Businesses with limited capital or lease constraints
Because they use hydrocarbon refrigerants like R290, they already comply with Australia’s upcoming low-GWP regulations.
However, plug-in systems produce heat inside the store, which can raise indoor temperatures and increase air-conditioning costs. They also rely on multiple small compressors, each with its own maintenance schedule.
Remote Systems: Engineered for Efficiency
Remote systems centralise refrigeration into one plant, supplying multiple cases and cold rooms throughout the store.
The benefits include:
- Higher efficiency: Shared compressors and condensers reduce total power use.
- Lower noise and heat: Equipment sits outside, creating a better in-store environment.
- Simplified maintenance: Service teams can access all components in one location.
- Future-proof design: Easily integrates with CO₂ technology and energy-recovery options.
Comparing Costs and ROI
While plug-in systems are cheaper upfront, remote systems deliver better long-term ROI through lower running costs, easier maintenance and extended equipment life. For large supermarkets, energy savings can repay the additional investment in just a few years.
The Hybrid Approach
Many modern retailers now combine both, using plug-ins for flexible areas like impulse drink zones or seasonal promos, while relying on remote systems for high-load departments like dairy, frozen, and produce.
This hybrid strategy balances flexibility and efficiency.
Design Expertise Matters
Choosing the right setup requires holistic design, not just product selection. Baker Refrigeration’s engineering and drafting teams model heat loads, airflow and refrigerant capacity to recommend the optimal balance for each store.
The best refrigeration solution isn’t one-size-fits-all. Plug-ins deliver convenience; remote systems deliver efficiency. The right combination delivers both.
Ask Baker Refrigeration to assess your store’s refrigeration profile and design a solution that meets your energy, layout and service goals.
