Large cold storage room repair in Egypt — for logistics warehouses that require a stable temperature between 2°C and 8°C. We use heavy-duty, high-capacity refrigeration systems. Brands: Bitzer, Guntner, Kelvion. Call **16062** for engineering service.
Logistics cold storage rooms feature huge floor areas and high ceilings, and use dual-discharge evaporators to distribute air across the whole space. They rely on semi-hermetic compressors and PLC control systems. Common faults include compressor oil pump failure, refrigerant leaks across the long piping network, and electronic expansion valve failure.
The most frequent faults we encounter while servicing Cooler Room — ranked by occurrence.
Faulty oil pressure switch or oil pump — 35%
Refrigerant leaks from brazed joints due to vibration
Electronic expansion valve (EEV) failure
Clogged oil filter and main drier filter
Faulty communication cables between the sensors and the PLC panel
Burned-out 3-phase fan motors
Overhaul and service of Bitzer and Copeland semi-hermetic compressors
Weighing in R-404A/R-134a charge and nitrogen leak detection
Replacing and calibrating electronic expansion valves (EEV)
Cleaning and washing evaporators and condensers with high-pressure equipment
Repairing and programming PLC control panels (Schneider)
Changing oil and internal filters for the large compressors
Calibrating and protecting electrical circuits against voltage fluctuation
A semi-hermetic compressor can be disassembled, overhauled and have its internal parts replaced, which is essential for large capacities because full replacement is very expensive.
To verify that cooling reaches every pallet in the warehouse, especially in pharmaceutical stores that are under strict Ministry of Health oversight.
On-site diagnosis, clear pricing before any work, and a 6-month written warranty.
