Overview
The EXTRCOOL AI-driven variable frequency refrigeration unit features a split-type design tailored for industrial and commercial cold chain applications. Core components include a multi-row L-shaped large evaporator, an EVI double rotor compressor, a 560DC variable-speed fan, and dual electronic expansion valves (EEV/EVI). The system enables precise temperature control and energy-efficient operation, maintaining stable and high-performance cooling even under low-temperature conditions, with optional 5G remote management support. The unit is equipped with condensate drain pipe frost protection heating, large-pitch fins (2.4–6mm), and a stainless steel sheet metal casing with a corrosion-resistant coating (customizable fin options available). The chassis features a hot refrigerant deicing system to resolve ice buildup on the evaporator and base pan. Ideal for cold storage, food processing, and pharmaceutical preservation.

Brief Advantage
Traditional cold storage refrigeration units often suffer from high energy consumption, unstable temperature control, frequent manual maintenance and severe inventory loss. The EXTRCOOL AI Driven Inverter Air Cooled Cold Storage Refrigeration Unit integrates intelligent AI algorithms, high-efficiency inverter technology and air-cooled modular design to deliver autonomous and adaptive refrigeration. It continuously learns and analyzes real-time data such as ambient temperature, storage capacity, door opening frequency and equipment operating status, automatically adjusting compressor speed, cooling output and defrost cycles for ultra-stable internal temperature and minimal fluctuation.

Core Components & Key Design Features

• Wide Temperature Adaptability: Reliable operation across -35°C to 52°C ambient conditions.
• High-Efficiency Evaporator Design: Optional external/inner rotor fans with 2.4–6mm large-pitch fins for optimal heat exchange.
• Corrosion-Resistant & Customizable Build: Stainless steel coated fins with options for harsh environments.
• Comprehensive Anti-Icing Protection: Condensate drain pipe frost heating and chassis hot refrigerant deicing system.

AI Frequency Conversion Advantages

• Higher Energy Efficiency: Increased COP and reduced operating costs vs fixed-speed units.
• Fast Cooling Performance: Broadband operation with one-key control for quick cooling.
• Extended Unit Lifespan: Frequency modulation reduces frequent startups and component wear.
• Precise Temperature Stability: Tight temperature control to preserve product quality.
• Quiet Operation: Low noise levels suitable for various environments.
• Flexible Compatibility: Works with photovoltaic generation without additional inverter.

Hot Fluoride Defrosting Benefits

• Ultra-Short Defrost Cycles: Completes defrosting in minutes, faster than electric defrosting.
• Minimal Temperature Fluctuation: Keeps variation narrow to protect food freshness.
• Lower Operating Costs: High utilization rate yields greater energy efficiency vs electric alternatives.
• Reduced Maintenance Needs: Stable technology reduces part replacements.

Hot Fluorine Ice-Melting Features

• Precision Ice Removal: Preheats before defrosting to prevent ice scraping damage to the evaporator.
• Significant Energy Savings: Uses high-efficiency thermal energy to reduce power consumption.
• Automatic Operation: Starts automatically under harsh conditions to prevent shutdowns from ice buildup.
• Enhanced Operational Safety: Uses high-temperature exhaust to melt ice safely, even with unstable power supply.

Application Fields
Precise temperature control with tolerance of ±0.5°C within the range from -20°C to 40°C, intelligently controlled by AI-driven frequency conversion. Typical applications include pharmaceutical & chemical precision temperature control, cold chain warehousing with zoned temperature management, food processing constant temperature storage, hypermarket temperature control, and melons & fruits precision ripening and temperature raising.
