Cold room engineering assessment Cape Town

Why we charge for a professional cold room engineering assessment.

A commercial cold room is an engineered refrigeration system, not just an insulated box. Fixakitchen offers a Cold Room Engineering Assessment from R2,500 so the room can be sized around the real heat load, product movement, door traffic and operating conditions.

Cold Room Engineering Assessment from R2,500 This is not a quick free quote. It is a refrigeration study used to design, size, commission and maintain a cold room around your business.

Why free dimension-only quotes can fail

Measuring the room is not the same as engineering the refrigeration system.

Many companies visit site, measure the room and quote from dimensions alone. At first glance that can feel cheaper. In reality it can lead to systems that are oversized, undersized, inefficient or forced to work harder than they were designed to.

A compressor that appears acceptable while the room is empty may struggle once hundreds of kilograms of warm product are loaded, staff open the door repeatedly and the surrounding kitchen temperature rises. The result can be long run times, poor recovery, iced evaporators, product spoilage and premature component wear.

UndersizedPoor pull-down, long compressor run time and weak recovery after loading.

OversizedShort cycling, poor humidity control, unnecessary cost and unstable operation.

Wrong airflowHot spots, iced coils, blocked product zones and poor evaporator placement.

Poor maintenance accessHard-to-service fans, drains, coils, controls and condensing units.

What we calculate

Every detail affects the refrigeration load.

Our engineering assessment considers room construction, product load, turnover, door traffic, ambient conditions, equipment heat and future growth before selecting refrigeration capacity.

Room and panel dataInternal dimensions, insulation thickness, panel construction, floor details, solar heat gain and nearby kitchen temperatures.

Product loadProduct type, storage volume, product weight, incoming product temperature, target temperature and pull-down requirement.

Door and staff trafficNumber of openings per day, average door open time, staff movement, loading patterns and strip curtain needs.

Internal heatPeople, lights, evaporator fans, motors, machinery and any other equipment operating inside the room.

Airflow and stackingEvaporator placement, air paths, shelf spacing, product stacking, clearance zones and blocked airflow risks.

Future expansionPossible product growth, new delivery patterns, extra shelving and later changes to room usage.

Total heat load Panel gain + product pull-down + door infiltration + internal gains + safety margin = refrigeration duty

Professional installation and commissioning

A correctly engineered system still needs correct commissioning.

Once the system has been engineered, installation must follow refrigeration best practice. Commissioning measurements prove that the system is sealed, dry, correctly charged and operating under real site conditions.

Nitrogen pressure testing and leak detection.
Triple evacuation where required and deep vacuum to at least 500 microns.
Vacuum decay testing before refrigerant charging.
Refrigerant charging by measured weight.
Verification of operating pressures, superheat and subcooling.
TXV or EEV operation checks and controller configuration.
Temperature and pressure sensor verification.
Defrost setup, airflow balancing and final performance testing.

Preventative maintenance planning

A cold room is an investment that needs a service plan.

Fixakitchen can develop a maintenance schedule based on how your cold room is used. The goal is to catch airflow, drain, gasket, condenser, sensor and refrigerant issues before they become emergency stock-loss events.

Monthly checksCondenser condition, temperature logs, door gaskets, drains, alarms and visual leak indicators.

Performance recordsOperating pressures, superheat, subcooling, compressor run behaviour and energy trends.

Hygiene and airflowEvaporator cleaning, shelf clearance, fan condition, drain sanitation and blocked airflow risks.

ControlsSensor calibration, defrost timing, controller settings, EEV configuration and planned service reminders.

Engineered for performance. Designed for reliability.
