CTCMA303DF

Description

Frozen storage facilities require powerful and efficient refrigeration systems. Therefore, many businesses prefer a monoblock refrigeration unit because it integrates the condenser and evaporator into one compact system. As a result, installation becomes faster and maintenance becomes easier.

The ColdTech ceiling mounted monoblock refrigeration unit model CTCMA303DF is designed for medium to large freezer cold rooms that require strong cooling performance. The system operates on 220–240V power and features a 3.0 HP motor with a cooling capacity of approximately 3305 W. Consequently, it delivers reliable refrigeration for frozen food storage and commercial cold room applications.

Moreover, the unit maintains a working temperature range between −20°C and −10°C, which makes it suitable for freezer storage environments. Because the system is ceiling mounted, it helps optimize internal space while ensuring balanced airflow inside the cold room. In addition, the unit uses R404A refrigerant and hot gas defrost technology to maintain consistent cooling performance.

However, efficient freezer operation also depends on proper cold room insulation and professional installation. Therefore, businesses should collaborate with an experienced cold room manufacturer or reliable cold room supplier. In the GCC region, choosing a trusted cold room supplier in UAE ensures efficient and durable frozen storage solutions.
