1. Product Overview

The cabinet-type condensing unit is an integrated refrigeration system specifically designed for modern commercial freezing and refrigeration requirements. Unlike traditional open-type units, this product employs a fully enclosed cabinet structure, integrating the compressor, condenser, receiver, and electrical control system within a weatherproof metal housing.
Not only does it resolve the issues of excessive noise and unsightly appearance associated with conventional units, but it also offers exceptional weather resistance. It can be directly installed on external walls or rooftops without requiring a dedicated plant room. This makes it an ideal power source for convenience store refrigeration cabinets, hotel kitchen cold stores, pharmaceutical refrigeration, and small to medium-sized cold storage projects.

3. Key Features and Technical Advantages
3.1 Ultra-low Noise Design
This represents the unit's most compelling selling point. Particularly suited for noise-sensitive residential areas or commercial centres:
Soundproof enclosure: Internal high-density acoustic insulation effectively blocks high-frequency compressor noise.
Low-noise fan: Utilises an external rotor axial fan with large blades and low rotational speed, significantly reducing airflow noise while maintaining air volume.
Vibration-damping structure: Both the compressor and piping system undergo vibration-damping optimisation to minimise resonance.
3.2 Weatherproof & Durable Outdoor Design
Corrosion-Resistant Enclosure: Constructed from thickened galvanised steel plate with electrostatic powder coating (typically white or grey), offering rust, corrosion, and UV resistance.
Rainproof Structure: Unique louvred or deflector design prevents rainwater ingress into electrical cabinets, eliminating the need for separate rain shelters.
3.3 Side-Discharge Airflow & High-Efficiency Heat Exchange
Heat exchanger: Features high-efficiency internally threaded copper tubes wrapped in hydrophilic aluminium foil fins, with U-shaped or L-shaped configurations maximising frontal surface area.
Side-discharge airflow: Scientifically organised airflow not only ensures superior heat dissipation but also facilitates installation in confined spaces (e.g., building facades) without occupying excessive passageway space.
3.4 High Integration, Easy Installation
Complete Components: Pre-installed at factory with receiver, dryer filter, sight glass, solenoid valve, high/low pressure controller, and junction box.
Plug-and-Play: Field installation requires only connecting copper pipes and power cables for operation, significantly reducing contractors' project timelines while minimising leakage risks associated with on-site welding.
