Cold Storage Integrated Unit 1.5–5.5HP Wall-Mounted

The Cold Storage Integrated Unit 1.5–5.5HP Wall-Mounted is a compact and efficient refrigeration solution, ideal for small to medium-sized cold rooms and refrigeration applications. This unit combines a condenser, evaporator, and compressor in a space-saving design that can be directly wall-mounted. Designed for reliable cooling performance, it offers quiet operation, low power consumption, and user-friendly maintenance access. The system uses R404A refrigerant and features electronic expansion valves for precise temperature regulation, making it suitable for stable refrigeration even in variable ambient conditions.
