Explosion proof refrigerator cabinet refrigeration model for university laboratories

Explosion proof refrigerator cabinet refrigeration model for university laboratories

Scope of Application

This product is mainly suitable for laboratories, preparation rooms, and small transit warehouses involving flammable and explosive dangerous goods (such as organic solvents, certain volatile chemicals, active samples that require low-temperature storage, etc.) in chemistry, chemical engineering, materials, biotechnology, medicine, and other fields. Specially suitable for indoor locations where explosive gas environments (Zone 1 or Zone 2) or dust environments (Zone 21 or Zone 22) may exist. Not suitable for storing highly corrosive or special handling media. Before use, it is necessary to confirm the compatibility between the stored material and the equipment material.

product structure

The equipment adopts a sturdy cabinet style vertical structure, usually consisting of the following core parts:

1. Explosion proof system:The core components include explosion-proof compressors, explosion-proof temperature controllers, explosion-proof lighting fixtures, explosion-proof junction boxes, and intrinsic safety circuits. All electrical components are specially designed and packaged to meet the specified explosion-proof level (such as Ex d IIB T4 Gb or higher), ensuring that internal sparks or high temperatures are isolated.

2. Thermal insulation box:Adopting high-strength metal outer panels and efficient environmentally friendly polyurethane foam insulation layer, the door body is equipped with magnetic sealing strips and explosion-proof door locks to ensure insulation performance and prevent accidental opening.

3. Refrigeration system:Efficient and energy-saving explosion-proof compressor refrigeration unit, combined with optimized air cooling or direct cooling cycle, ensures uniform and stable temperature inside the cabinet.

4. Inner liner and storage rack:The inner liner is mostly made of corrosion-resistant stainless steel material, equipped with adjustable height anti slip glass or steel shelves for easy classification, storage, and observation of items.

5. Safety attachments:Usually includes explosion-proof door switches, over temperature alarm devices, mechanical locks, and necessary safety warning signs.

Product Features

1. Intrinsic safety:The core electrical components are fully explosion-proof, fundamentally eliminating the possibility of igniting explosive environments.

2. Precise temperature control:Adopting explosion-proof microcomputer controller, digital display, precise temperature control, small fluctuations, ensuring the quality of stored materials.

3. Efficient and energy-saving:Optimize the design of the refrigeration system and efficient insulation layer to reduce energy consumption while ensuring performance.

4. Durable and reliable:Stainless steel inner liner and high-quality metal shell, anti-corrosion and rust proof, easy to clean. The key components are sturdy and durable.

5. Humanized design:The internal space layout is reasonable, and the shelves are adjustable. Some models have sound and light alarm functions, which can promptly prompt abnormal temperature or door not tightly closed conditions.

Installation and maintenance

1. Installation:It must be operated by professionals. It should be placed on a flat and sturdy ground with good ventilation, away from sources of fire, heat, and direct sunlight. Ensure that there is sufficient heat dissipation space on the back and sides of the box (usually recommended to be greater than 10 centimeters). The power supply must be connected to a dedicated circuit that meets explosion-proof requirements and reliably grounded.

2. Maintenance:Keep the inside and outside of the box clean on a daily basis and avoid using corrosive cleaning agents. Regularly check the sealing of the door seal and whether the radiator is clogged with dust. Users are strictly prohibited from disassembling or modifying any electrical components on their own. If any abnormalities occur (such as lack of cooling, excessive noise, alarm, etc.), the power should be immediately cut off and professional personnel should be contacted for maintenance. It is recommended to develop a regular professional inspection plan to ensure the continuous effectiveness of explosion-proof performance.

In short,Explosion proof refrigerator cabinet refrigeration model for university laboratoriesThrough its specialized structural design, it significantly enhances the intrinsic safety level of the laboratory while providing a stable refrigeration environment, making it a key component of hazardous material safety management.
