Cases, coolrooms and racks that hold temperature through peak trade
A supermarket's refrigeration is spread across display cases, walk-in coolrooms, freezers and a central plant room, and it is often the largest electrical load in the store. We design, install and maintain retail refrigeration — including transcritical CO₂ racks — and measure what it costs to run.
What the refrigeration has to deliver
Product held at display temperature
Open cases work against store air, lighting and customers all day. Case selection, controller setup and defrost timing are matched so product stays in range without chilling the aisle.
Work around trading hours
A store cannot close for a plant change. Installs, case replacements and changeovers are staged out of hours, with temporary cooling arranged where product would otherwise be at risk.
A lower power bill
We log how the plant runs, then adjust head pressure, defrost and setpoints, and cost any upgrade against its running cost so the decision rests on payback.
The move off HFCs
The HFC phase-down is pushing retail refrigeration toward CO₂ and hydrocarbons. We design and install transcritical CO₂ racks and R290 cabinets, and plan the transition of existing stores.
Breakdowns on a trading day
When a case or rack fails, the 24/7 line reaches the technician who does the diagnosis. Programmed maintenance keeps condensers clean and controllers set so it happens less often.
A hot summer is a design condition
Rooftop plant is selected for the ambient temperatures the site actually sees, not a mild-climate rating. This matters most for transcritical CO₂, where efficiency depends heavily on how cool the gas cooler can run. Gas cooler sizing, adiabatic assistance and control strategy are decided at design stage, when they cost least to get right.
Cases, controls and plant as one system
Case controllers, electronic expansion valves and rack controls are set up together, so the plant runs to the load of the store rather than a fixed setpoint. Commissioned as a system, head pressure can float down overnight, defrost can run on demand, and alarms reach someone who can act on them.
Small format and specialty retail
Not every store has a plant room. Butchers, delis, bakeries, liquor stores and convenience stores run on self-contained cabinets, walk-in coolrooms and remote condensing units. They get the same approach — load worked out, equipment selected to suit, maintenance scheduled to the duty — sized to the site.
