Diagnosis and repair of insulated walk-in cold rooms — panels, doors, evaporators, condensers and control systems — restoring holding temperature fast to protect perishable stock.
A walk-in cold room that drifts above temperature is almost always losing its hold through the gas circuit, an iced-up evaporator coil or a breached door seal. We restore the panel, seal and refrigerant charge, then verify the room holds temperature under a full load before we sign it off. Site B is one of the largest and busiest parts of Khayelitsha, and its dense trading streets are lined with spaza shops, butcheries and takeaway kitchens that all live or die by their cold storage.
