Overview
The bioengineered explosion-proof refrigerator (horizontal freezing type) is a special low-temperature storage equipment designed specifically for laboratories or production areas with flammable and explosive risk environments in biotechnology, biopharmaceuticals, chemical synthesis, and other fields. It adopts a horizontal structure, which not only achieves deep freezing (usually up to -25 ℃ to -40 ℃) function, but also all electrical components and refrigeration systems have undergone strict explosion-proof design and certification. It can be safely applied in environments where volatile solvents, flammable gases or dust may exist, fundamentally eliminating the risk of explosion caused by electric sparks or high-temperature surfaces. It is one of the core equipment to ensure the safety of high-risk scientific research and production.
Product Details
Bioengineered Explosion proof Refrigerator (Horizontal Freezing Type)
Product Introduction
This product is designed as a horizontal cabinet, usually with a large volume, making it easy to store large amounts of biological samples, enzyme preparations, bacterial strains, standards, or intermediate products. Its core lies in combining efficient compressor refrigeration systems with comprehensive explosion-proof technology, ensuring that the entire machine (including compressors, thermostats, lighting, switches, etc.) meets the explosion-proof requirements of Zone 1 or Zone 2 explosive gas environments while providing a stable and uniform low-temperature environment. The box doors are often lifted upwards, with reinforced sealing strips, excellent insulation performance, and equipped with explosion-proof digital temperature display and alarm systems.
Scope of Application
Mainly applicable to the following locations with potential explosive environments:
Bioengineering laboratories, especially areas involving organic solvent extraction, fermentation exhaust, or flammable chemical operations.
Low temperature storage area for raw materials, intermediates, and finished products of pharmaceutical companies.
The R&D and quality inspection departments that intersect with biotechnology in the chemical and petrochemical industries.
Any location that requires low-temperature storage of flammable and explosive chemicals or samples.
product structure
1. Cabinet:The internal and external boxes are made of high-quality stainless steel, and the middle is filled with high-strength polyurethane foam insulation layer. Horizontal structure with hinged top cover, equipped with reinforced door seal and air pressure balancing device.
2. Refrigeration system:Key components such as explosion-proof fully enclosed compressors, explosion-proof condensing fans, evaporators, etc. are integrated into specially designed explosion-proof chambers or designed with intrinsic safety.
3. Electrical system:All electrical components, such as explosion-proof temperature controllers, explosion-proof internal lighting fixtures, explosion-proof junction boxes, etc., are integrated into independent explosion-proof control boxes.
4. Security system:Including over temperature sound and light alarm device, explosion-proof door lock, pressure relief safety device, and multi-point temperature sensor.
Technical Requirements
Explosion proof rating: usually not lower than Ex d ib mb IIB T4 Gb/Ex tb IIIC T135 ° C Db, depending on the usage environment.
Temperature range: -10 ℃ to -40 ℃ (adjustable), fluctuation ± 2 ℃.
Safety standards: comply with GB 3836 series Chinese explosion-proof standards and relevant international standards (such as IEC 60079).
Material: The inner container and shelves are made of corrosion-resistant stainless steel, which is easy to clean and disinfect.
Installation and useBioengineered Explosion proof Refrigerator (Horizontal Freezing Type)
1. Installation:It must be carried out by professionals. The equipment should be placed on a flat ground with good ventilation, away from heat sources, and easy to dissipate heat. The power connection should comply with explosion-proof electrical installation specifications and ensure reliable grounding. Adequate space should be reserved around to ensure the heat dissipation efficiency of the condenser.
2. Use:Before use, it is necessary to confirm that the environmental hazardous medium matches the explosion-proof level of the equipment. Items stored should be sealed to avoid volatilization. Regularly check the sealing of the door seal and the frost inside the box.
3. Security maintenance:Any cleaning, defrosting, or maintenance must be carried out after cutting off the power. Users are strictly prohibited from disassembling or modifying any explosion-proof components on their own. If there is a malfunction or alarm, the power should be cut off first and repaired by qualified professionals. It is recommended to establish a regular inspection system to ensure the continuous effectiveness of explosion-proof performance.
