Explosion proof refrigerator for hazardous chemicals

Explosion proof refrigerator for hazardous chemicals

Product Introduction

This device has a similar appearance to an industrial refrigerator, but its core is completely different. All electrical components such as the refrigeration system, temperature controller, internal lighting, switches, and even fans have undergone special explosion-proof packaging or intrinsic safety design to ensure that they may accumulate inside and will not become ignition sources. Internally, corrosion-resistant stainless steel liners are typically used, equipped with adjustable shelves for flexible spatial layout. Equipped with a precise electronic temperature control system and capable of maintaining a set low-temperature environment (commonly such as+4 ℃, -20 ℃, etc.), effectively suppressing chemical volatilization and ensuring its stability.

Scope of Application

Mainly applicable to all fields involving volatile hazardous chemicals, such as scientific research, chemical engineering, pharmaceuticals, energy, universities, etc. Typical storage materials include organic solvents such as ethers, alcohols, ketones, alkanes, etc; Standard solution; Some experimental samples that are prone to spontaneous combustion or unstable when exposed to heat; And chemical intermediates that require low-temperature storage. It is a safety supplementary storage plan for Class A and Class B dangerous goods warehouses or laboratories.

Technical Requirements

1. Explosion proof certification:It is necessary to obtain an explosion-proof certificate issued by national institutions, and the explosion-proof level is usually not lower than Ex d IIB T4 Gb or Ex ib IIB T4 Gb, to ensure safe use in the corresponding hazardous area.

2. Temperature performance:Accurate temperature control, minimal fluctuations, and equipped with sound and light alarm functions for overheating and sensor failure.

3. Safety design:Adopting explosion-proof door locks, self closing hinges, and internal explosion-proof lighting. Ventilation systems or pressure relief devices can effectively prevent gas accumulation. The material needs to be resistant to chemical corrosion.

4. Electrical specifications:Comply with the installation and use specifications for explosion-proof electrical equipment, and the power supply incoming line must be equipped with isolation and sealing devices.

Installation and maintenance

Installation:It must be operated by professionals. It should be placed on a sturdy and flat ground with good ventilation, away from heat sources and open flames. Ensure that the box is reliably grounded. The power supply must meet the equipment requirements and is recommended to be equipped with an independent switch or leakage protection.

maintain:Regularly inspect electrical circuits, seals, and refrigeration performance by professional personnel. In daily use, it is necessary to promptly clean up any spilled chemicals inside and keep the inner container clean. It is strictly prohibited to store chemicals that are highly corrosive or directly react with the material of this equipment. If not used for a long time, the power should be cut off, defrosted, and cleaned, and the box door should be kept slightly open for ventilation.

summary

Explosion proof refrigerator for hazardous chemicalsBy deeply integrating refrigeration technology with the concept of intrinsic safety, a crucial 'safe low-temperature space' has been provided for high-risk chemicals. Proper selection, standardized installation, and regular maintenance are key to ensuring long-term reliable operation and eliminating safety hazards, and are an important part of the safety management system in modern chemical and scientific research institutions.
