About This Service
Ali Hassan Marine’s commercial refrigeration service covers the full spectrum of refrigeration equipment used in the commercial sector — from display cases and under-counter units to central refrigeration systems and blast chillers. Our certified technicians diagnose faults accurately, carry out reliable repairs, and provide ongoing maintenance support that keeps your refrigeration assets performing at their best through UAE’s demanding climate.
Commercial Refrigeration Services We Provide
Refrigeration System Diagnostics
We perform thorough diagnostics on all types of commercial refrigeration equipment — measuring pressures, temperatures, electrical performance, and refrigerant condition. Accurate diagnosis ensures the right repair is carried out first time.
The compressor is the most critical component in any refrigeration system. We service, repair, and replace compressors across all major brands to restore reliable cooling performance
Refrigerant Leak Detection & Repair
Refrigerant leaks reduce cooling performance and increase energy consumption. We use electronic leak detection to locate all leak points, repair them, and recharge the system correctly.
Display Case & Merchandiser Servicing
Supermarket display cases, glass door merchandisers, and deli counters require regular servicing to maintain consistent temperatures and protect food safety. We service all major commercial display refrigeration brands.
Blast Chiller & Freezer Repair
Blast chillers are critical for food safety compliance in commercial kitchens. We diagnose and repair blast chiller faults quickly to ensure your kitchen meets food hygiene requirements.
Scheduled servicing prevents costly failures, extends equipment life, and supports food safety compliance. We provide tailored maintenance plans for single sites and multi-location businesses
Common Commercial Refrigeration Problems We Fix
Commercial refrigeration systems in supermarkets, hotels, restaurants, and food storage facilities are subject to continuous demand and require consistent performance to protect product quality and food safety compliance. From compressor failure and refrigerant leaks to evaporator icing, condenser fouling, and temperature control faults, our engineers diagnose and resolve the full range of commercial refrigeration problems — delivering reliable refrigeration repair and maintenance services across UAE commercial facilities.
Unit Not Reaching Temperature
Refrigerant loss, dirty condenser coils, or compressor degradation reduce cooling performance. We identify the specific fault through full diagnostics and restore the unit to its operating temperature range.
Excessive Frost or Ice Buildup
Faulty door seals, defrost timer failures, or blocked drain lines cause ice accumulation inside refrigeration units. We identify the root cause and resolve it — not just defrost and leave.
Compressor Running Constantly
A compressor that never cycles off indicates a refrigerant shortage, thermostat fault, or heat load problem. Continuous operation damages the compressor and drives up energy costs.
Unusual Noises from Refrigeration Unit
Vibrating fans, loose panels, worn bearings, or liquid slugging in the compressor cause abnormal noise. Our engineers identify and resolve mechanical noise faults before they develop into failures.
Why Commercial Refrigeration Systems Fail
Commercial refrigeration systems fail due to mechanical wear, refrigerant loss, electrical faults, and inadequate maintenance — compounded by the extreme ambient temperatures across UAE commercial environments. Condenser fouling, compressor overload, evaporator icing, and thermostat faults are the most common failure points, each capable of causing temperature instability and product loss. Without regular servicing, refrigeration equipment deteriorates rapidly — increasing energy costs and risking food safety compliance.
UAE Heat and Seasonal Load Increases
Ambient temperatures in the UAE place heavy thermal loads on air-cooled condensing units. During peak summer months, systems that are marginally maintained often fail under increased heat stress.
Continuous Operation Without Servicing
Commercial refrigeration typically runs 24 hours a day. Without regular servicing, coils foul, refrigerant leaks develop, and wear items deteriorate — turning small issues into major failures
Door Seal Neglect
Worn door gaskets on display cases and cold rooms are one of the most common causes of performance loss and high energy consumption. Regular inspection and replacement prevents this entirely avoidable problem.
Aging Equipment in High-Demand Environments
Commercial kitchens, supermarkets, and food warehouses operate equipment hard. Aging refrigeration systems in these environments need proactive maintenance and timely component replacement to remain reliable.
Our Commercial Refrigeration Service Process
Our commercial refrigeration service process begins with a thorough system diagnostic to identify mechanical, electrical, and refrigerant-related faults across all equipment. Our engineers carry out targeted repairs and preventive maintenance to manufacturer specifications — cleaning heat exchange surfaces, checking refrigerant charge levels, testing controls, and verifying temperature accuracy throughout. Every service visit is fully documented, ensuring UAE supermarkets, hotels, and food service operators have a complete maintenance record and fully restored refrigeration performance.
Step 1: Equipment Assessment
Our technician assesses the unit’s operating condition — reviewing fault history, running temperatures, and any alarm codes before beginning diagnostic testing.
Step 2: Full System Diagnostics
We measure refrigerant pressures, superheat and subcooling values, electrical parameters, and airflow conditions to build an accurate picture of system health and fault location.
Step 3: Repair & Component Work
Identified faults are repaired using quality replacement parts. Refrigerant handling is carried out in full compliance with UAE regulations, and all work is documented.
Step 4: Performance Verification & Handover
The repaired unit is run to verify it reaches and holds the correct operating temperature. A service report covering all work completed is issued at job completion.
We contacted them for our chiller units and split AC systems at our factory. Their team handled the compressor change professionally and completed the new split AC installations on schedule. Clean work, no mess left behind, and the systems have been running perfectly ever since. Highly dependable.
The team was mobilised quickly to our vessel MV Green Land. They carried out a full compressor overhaul and reinstallation in the ECR room and fitted the new 5-ton 60Hz AC units without any delays. Their understanding of marine electrical systems and refrigeration gave us full confidence. Excellent execution from start to finish.
They serviced all AC units aboard MV White Land, replaced the faulty compressor, and installed both 3-ton and 5-ton 60Hz units. The team worked efficiently within our port window and left the systems fully operational. We will continue working with them for future maintenance across our fleet.
They mobilised to MV AM Princess with a full team and tools. The entire refrigeration system was recovered, flushed, pressure-tested and vacuumed before recharging with R404A. The expansion valve, orifice, and drier cores were all replaced with new parts. The system passed pressure hold for a full hour before recharge. It's running in perfect condition now. Thorough, documented, and professional.
