All-Aluminum Evaporator Solves Core Pain Points of 24H High-Humidity Supermarket Air Curtain Cabinets

Supermarket air curtain cabinets operate 24/7 in continuous high-humidity environments, with long-term condensation, frequent defrost cycles, and complex air pollutants. For mainstream commercial refrigeration equipment manufacturers, traditional copper tube-aluminum fin evaporators have become a major bottleneck restricting product competitiveness and after-sales stability. Against the backdrop of soaring global copper prices, the widespread upgrade to all-aluminum tube fin evaporators has become an inevitable industry trend.

Our optimized full aluminum tube aluminum fin evaporator completely targets the pain points of supermarket air curtain cabinet operation, realizing dual upgrades of corrosion resistance stability and cost control:

1. Homogeneous all-aluminum structure, zero galvanic corrosion & ultra-low leakage rate

Adopting 1060 high-purity aluminum tubes and hydrophilic aluminum fins with consistent material properties and thermal expansion coefficients. There is no metal potential difference between tubes and fins, fundamentally eliminating electrochemical corrosion and welding perforation problems of copper-aluminum hybrid structures. It perfectly adapts to 24-hour uninterrupted high-humidity refrigeration and frequent defrost working cycles, reducing equipment failure and after-sales maintenance rate by more than 70%.

2. Professional hydrophilic anti-corrosion coating, long-term stable operation

The surface is treated with high-performance hydrophilic anti-corrosion coating, which forms a dense protective oxide layer. It effectively resists condensate erosion, food volatile corrosion and humid air oxidation, with salt spray resistance up to 1000 hours. It maintains efficient and stable heat exchange performance for a long time in supermarket fresh food, fruit and dairy display environments, extending the overall service life of the cold cabinet.

3. Significant cost reduction, greatly enhance OEM market competitiveness

Under the current high copper price environment, the all-aluminum solution reduces the raw material cost of a single evaporator by30%–38%. It completely gets rid of the cost shackles of copper materials, helping cold chain equipment manufacturers optimize product pricing, expand profit margins, and occupy a dominant position in the low-price and high-quality market competition.

4. Optimized fin structure, energy-saving and anti-clogging

Customized wide-pitch louver fin design avoids dust, water scale and fine debris blockage in supermarket environments, ensuring smooth air circulation and stable heat exchange efficiency. Lower air resistance reduces compressor load, achieving obvious energy-saving effects and meeting the energy efficiency upgrade requirements of modern commercial cold cabinets.

Application Scope & Industry Value

Widely applicable to supermarket vertical air curtain cabinets, fresh food display freezers, dairy refrigerators, convenience store constant temperature cold cabinets and other commercial refrigeration equipment. For domestic large-scale cold chain equipment factories, upgrading to all-aluminum evaporators is not only a passive alternative to high copper prices, but also an active strategic upgrade to achieve low failure rate, low maintenance cost and high market profitability.

We support full customization of size, fin density and surface treatment, providing one-stop aluminum-for-copper heat exchange solutions for global commercial cold chain manufacturers, with stable delivery and strict quality testing.
