Unit Cooler

Brine unit cooler is applied in processing rooms and cold rooms where normally ethylene glycol, etc. are used as refrigerant. 400/ 500/ 630 mm external rotor fan, 12.7mm bare cooper tube, corrugated fin, optimized piping design are adopted, featuring compact structure, low profile, low noise, highly efficiency, high performance and longer life.

❄️ ‌I. High-Efficiency Structure & Performance‌

1. ‌Compact & Low-Noise Design‌:
   Utilizes 400/500/630mm external rotor fans and a low side-height structure, saving space while reducing operational noise significantly.
2. ‌Enhanced Heat Transfer‌:
   Combines 12.7mm smooth copper tubes with corrugated fins and optimized circuit design, boosting heat exchange efficiency and cooling performance.

⚙️ ‌II. Deep-Freeze Adaptability‌

1. ‌Wide Temperature Coverage‌:
   Compatible with brine-based coolants (e.g., ethylene glycol, propylene glycol), suitable for environments ranging from -18°C cold storage to -35°C rapid-freezing rooms (e.g.,GFL series).
2. ‌Freeze & Corrosion Resistance‌:
   Coolants remain liquid down to -50°C, with non-corrosive properties ensuring long-term stability.

🛡️ ‌III. Reliability & Maintainability‌

1. ‌Modular Durability‌:
   Powder-coated aluminum casing + stainless steel core components (e.g., ECG series) resists high-humidity corrosion, extending lifespan by >50%.
2. ‌Easy Maintenance‌:
   Double-layer drain pans (hinged outer pan + sloped inner pan) enable quick disassembly and cleaning, minimizing downtime.

💡 ‌IV. Energy Efficiency & Eco-Friendliness‌

1. ‌Optimized Energy Use‌:
   Triangular coil arrangement (38.1×33mm tube spacing) and hydrophilic aluminum fins (4–6mm fin spacing) synergistically reduce energy consumption.
2. ‌Environmental Compliance‌:
   Replaces fluorinated refrigerants with water-based coolants, eliminating ozone depletion risks and aligning with green refrigeration standards.

🏭 ‌V. Scenario Adaptability‌

1. ‌Versatile Applications‌:
   Ideal for processing rooms, cold storage (meat/seafood), pharmaceutical cold chains, and high-humidity environments.
2. ‌Customizable Configurations‌:
   Supports tailored fin spacing/airflow designs (DL/DD/DJ models) for precise temperature control (-5°C to -55°C).
