CTCMA305DF

Description

Frozen storage environments require reliable refrigeration systems that can maintain stable low temperatures. Therefore, many businesses prefer a monoblock refrigeration unit because it integrates the condenser and evaporator into a single compact structure. As a result, installation becomes faster while maintenance remains simple.

The ColdTech ceiling mounted monoblock refrigeration unit model CTCMA305DF is designed for medium to large freezer cold rooms that require consistent cooling performance. The system operates on 380–400V power and features a 3.0 HP motor with a cooling capacity of around 3050 W. Consequently, it delivers dependable 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 conditions. Because the system is ceiling mounted, it helps optimize the internal space of the cold room while ensuring efficient airflow distribution. In addition, the unit uses R404A refrigerant and hot gas defrost technology to maintain stable and efficient cooling performance.

However, proper insulation and professional installation are essential for freezer cold rooms. 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.
