Overview:
The Box Type Heat Exchanger is a high-performance heat exchange device for refrigeration systems. Its robust cabinet-type structure offers a compact design, efficient heat dissipation, and low-noise operation. It’s ideal for commercial refrigeration (supermarkets, restaurants), industrial cold storage, and HVAC applications, ensuring stable temperature control.
2. Key Features & Technical Highlights:
Compact & Robust Design:
Cabinet-Type Structure: Massive box-type design (e.g., FNU-500: 14.7kW heat rejection) offers space-saving solutions suitable for indoor/outdoor installations.
Efficient Heat Exchange Coils: High-quality copper pipes with mechanically expanded fins ensure tight tube-fin contact for efficient heat dissipation (e.g., FNU-800: 22.4kW heat rejection).
Durable & Leak-Proof Construction:
Corrosion-Resistant Shell: Regular or optional stainless-steel shells, coated for resistance, ensure a long service life.
Leak-Proof Guarantee: 2.9MPa tested coils ensure zero refrigerant leakage, reducing maintenance costs.
Low-Noise Operation:
Internal Rotor Blowers: Operates quietly (below 60 decibels) with sufficient airflow (e.g., FNU-600 fan: 500mm diameter, 7000m³/h air volume).
3. Core Industry Applications:
Commercial Refrigeration:
Supermarkets/Retail: Maintains precise temperatures (2-8°C, -18°C) in display cases and storage, fitting well in limited spaces.
Restaurants/Food Service: Provides quiet, efficient cooling for walk-in units (-25°C to 5°C), preserving food quality.
Industrial Cold Storage:
Medium-to-Large: Ideal for facilities storing fruits, vegetables, meat, seafood (0°C to -25°C), with models like FNU-1200 (32.1kW heat rejection).
4. Customization Options:
Shell Material & Color: Stainless steel for corrosive environments; custom colors for branding.
Noise Reduction: Customizable to meet specific noise requirements for sensitive applications.
