1. Product Overview

2. Main Structural Features

• High-quality Aluminum Alloy Frame Structure: The whole outer frame of the cabinet is made of thickened high-grade aluminum alloy profiles, which boasts strong impact resistance, permanent anti-rust and anti-corrosion properties, and ultra-long service life. Different from traditional iron and ordinary steel refrigeration cabinets, the aluminum alloy main body is light in weight, not easy to deform after long-term continuous use, firm and stable in overall structure, and elegant and neat in overall appearance.
• Bottom-mounted Integrated Refrigeration Unit Design: The core refrigeration components including compressor and condenser are integrally installed at the bottom of the cabinet body. This classic bottom unit layout features stable overall equipment placement, good grounding stability and no top heavy risk. It is convenient for daily heat dissipation ventilation, regular inspection, maintenance and parts replacement, and will not occupy the upper operating and storage space, making on-site placement and daily use more flexible and convenient.
• Efficient Forced Air Cooling Circulation System: Equipped with a professional dedicated air cooling evaporator and circulating air duct system, it forms a full internal air circulation convection, realizing fast cooling and rapid temperature stabilization. There is no temperature dead angle inside the cabinet, which effectively avoids temperature fluctuation, food deterioration and sample spoilage caused by uneven cooling, and ensures consistent storage temperature in all storage areas.
• High-density Polyurethane Integral Foam Insulation Layer: The cabinet wall is filled with high-density integral foamed polyurethane thermal insulation material, with excellent cold insulation and heat preservation performance. It effectively reduces cold air loss and external heat penetration, lowers overall equipment energy consumption, and maintains long-term stable low temperature inside the cabinet even during 24-hour uninterrupted continuous operation.
• Adjustable and Load-bearing Internal Storage Shelves: The interior is equipped with thickened heavy-duty movable storage shelves, which can be freely adjusted in height and quantity according to the size, specification and storage quantity of stored food, experimental samples and raw materials. The internal space is scientifically divided for classified storage, neat arrangement and quick access and inventory management of stored items.
• High-tightness Sealed Door with Safety Protection: The cabinet door is fitted with high-elasticity magnetic sealing strips, which ensures tight door closing and excellent cold locking effect, effectively preventing cold air leakage, dust ingress, moisture condensation and odor penetration. An optional dedicated safety anti-theft lock is available to meet the strict management needs of sample retention, special material storage and standardized safety supervision.

3. Core Performance Advantages

• Intelligent Precision Constant Temperature Control: Built-in digital intelligent temperature controller with real-time internal temperature digital display, precise temperature adjustment and automatic over-temperature alarm function. It can automatically monitor and adjust the internal storage temperature in real time, maintaining a safe, stable and constant low-temperature storage environment throughout the year.
• Rapid Cooling and Balanced Internal Temperature: The forced air cooling circulation design enables fast cooling speed and uniform temperature in every corner of the cabinet. It can effectively lock the freshness of stored food and keep experimental and batch samples stable for long-term retention, avoiding quality problems caused by temperature changes.
• Low Noise Operation and Energy Saving Efficiency: Adopting high-efficiency energy-saving low-power compressor and optimized mute operation structure, the equipment runs with low noise, stable operation performance and low daily energy consumption. It is suitable for long-term uninterrupted continuous operation in commercial catering, laboratory and industrial production environments.
• Hygienic Structure and Simple Daily Maintenance: The aluminum alloy surface is waterproof, oil-proof and wear-resistant, which can be quickly wiped and disinfected daily. The internal seamless integral structure avoids dirt and residue accumulation, fully complying with food safety production and sanitary management specifications and industry hygiene standards.
• Diversified and Wide Application Scenarios: Widely applicable for mandatory food sample retention in canteens and catering stores, fresh food refrigeration and raw material storage in food factories, long-term sample storage in quality inspection laboratories, and cold storage management of raw and auxiliary materials and intermediate products in pharmaceutical and cosmetic factories.
