CTCMA255DF

Description

Frozen storage facilities require reliable and efficient refrigeration systems. Therefore, many businesses choose a monoblock refrigeration unit because it combines the condenser and evaporator into one compact structure. As a result, installation becomes easier while maintenance remains simple.

The ColdTech ceiling mounted monoblock refrigeration unit model CTCMA255DF is designed for freezer cold rooms that demand higher cooling capacity. The system operates on 380–400V power and features a 2.5 HP motor with a cooling capacity of about 3130 W. Consequently, it delivers dependable refrigeration performance for frozen food storage and commercial cold room applications.

Moreover, the unit maintains a working temperature range between −20°C and −10°C, making it suitable for freezer storage environments. Because the system is ceiling mounted, it helps maximize internal space while ensuring proper airflow throughout the cold room. In addition, the unit uses R404A refrigerant and hot gas defrost technology to maintain stable and efficient 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.
