As the core carrier for the storage and supply of industrial gases, gas cylinders are widely used in laboratories, chemical engineering, manufacturing, healthcare and other scenarios. Improper storage of cylinders containing oxygen, acetylene, nitrogen, argon and other gases may cause leakage, combustion, explosion or tipping accidents. Current national standards such as the Safety Regulations for Handling, Loading/Unloading, Storage and Use of Gas Cylinders (GB/T 34525-2017) put forward systematic requirements for the design of gas cylinder rooms.

Combining two typical scenarios of indoor and outdoor application, DeSUN ECOTECH has launched large and small intelligent gas cylinder storage cabinets, providing an integrated hardware solution for the implementation of standardized management.

I. Design Specifications for Indoor Gas Cylinder Rooms: Representative of Laboratory Scenarios

Indoor storage mainly caters to gas consumption scenarios such as laboratories, medical institutions and small processing sites. The specifications require that: cylinder rooms shall be set independently or adopt dedicated gas cylinder cabinets, kept away from heat sources, open flames and flammable substances; good ventilation shall be maintained to prevent the accumulation of flammable gases; gas cylinders must be equipped with anti-tipping measures to avoid valve damage and leakage caused by tipping; flammable gases and combustion-supporting gases shall be stored in separate zones; leakage alarm devices shall be installed, and dedicated personnel management and ledger records shall be implemented.

Meanwhile, indoor gas cylinder cabinets shall have fireproof and explosion-proof performance, and the cabinet materials shall be flame-retardant and corrosion-resistant to meet the fire isolation requirements for a certain period of time in emergency situations. For space-constrained places such as laboratories, the equipment shall also feature compact size and convenient operation.

In response to these requirements, DeSUN ECOTECH’s small intelligent gas cylinder storage cabinets adopt flame-retardant steel and a three-layer fireproof structure, with full-cabinet explosion-proof performance to effectively resist external fire sources. The cabinet is equipped with adjustable fixing brackets, compatible with gas cylinders of various specifications from 2L to 40L, to prevent tipping. An intelligent leakage monitoring system detects cylinder leakage in real time and triggers alarms in case of abnormalities.

With a compact size, it can be placed in laboratory corners, outpatient gas points or storage areas of auto repair shops. It is fitted with a simple lock to realize dedicated personnel management, avoid accidental contact and loss, and is suitable for temporary storage and daily use of a small number of cylinders.

II. Design Specifications for Outdoor Gas Cylinder Rooms: Large-Batch Centralized Storage

Outdoor gas cylinder storage is commonly found in production areas of chemical enterprises, gas consumption zones of manufacturing plants, large-scale laboratories and gas supply stations, featuring a large number of stored cylinders, diverse gas types and variable environmental conditions. The specifications put forward higher requirements for outdoor cylinder rooms: they shall be kept away from fire sources and densely populated areas, and have rain-proof, sun-proof, lightning-proof and anti-static functions; natural or forced ventilation shall be maintained to discharge leaked gases in time; flammable, combustion-supporting and inert gases shall be stored in separate zones and separate warehouses; clear safety warning signs shall be set up; gas concentration monitoring, pressure and temperature parameter collection and early warning systems shall be equipped; gas cylinders shall be fixed to prevent tipping; batch storage sites shall also be equipped with explosion-proof electrical equipment and digital management capabilities to realize full-process traceability of gas cylinders.

DeSUN ECOTECH’s large intelligent gas cylinder storage cabinets are designed for such large-scale scenarios, in strict compliance with standards including GB/T 34525-2017. They integrate an intelligent monitoring system that collects real-time data of cylinder pressure, temperature and liquid level, triggers automatic audible and visual alarms in case of abnormalities and uploads data to the management platform. The ventilation system can discharge leaked gases in time to prevent combustion and explosion caused by the accumulation of flammable gases. Fixed anti-tipping brackets are compatible with cylinders of different specifications to eliminate tipping and leakage.

The cabinet body adopts thickened explosion-proof steel with anti-corrosion surface treatment, resistant to high and low temperatures and impact, adapting to harsh outdoor environments. The full-cabinet explosion-proof design meets the requirements of explosion-proof ratings such as Ex IIB T4/T6 and Ex IIC T4/T6, and has been certified by authoritative institutions. Meanwhile, the intelligent management system supports traceability of cylinder warehousing, outbound delivery and service life, realizing full-process digital management and meeting the comprehensive needs of outdoor cylinder rooms for batch storage, safety monitoring and accountability traceability.

III. Synergy of Indoor and Outdoor Scenarios: One-Stop Standardized Implementation

From a regulatory perspective, indoor cylinder rooms focus on space adaptation, fire and explosion protection, and dedicated personnel management; outdoor cylinder rooms emphasize large-batch storage, environmental tolerance, centralized monitoring and explosion-proof ratings. The two products from DeSUN ECOTECH complement each other: the small intelligent gas cylinder storage cabinets address daily safe storage of a small number of cylinders in laboratories, outpatient departments and small processing plants; the large intelligent gas cylinder storage cabinets serve large-scale gas consumption scenarios such as chemical engineering, manufacturing and gas supply stations.

Both take intelligent monitoring, explosion-proof design, anti-tipping fixation and digital management as core features, combining "human defense + technical defense" to reduce safety risks caused by human negligence.

Against the backdrop of increasingly strict standards and regular safety inspections, gas cylinder storage can no longer remain at the extensive stage of merely having cabinets and assigned personnel. With a product philosophy of standardization, modularization and intelligence, DeSUN ECOTECH provides replicable, verifiable and traceable solutions for the design of both indoor and outdoor gas cylinder rooms.

Whether for a few cylinders in a laboratory corner or large-batch centralized storage outdoors in factory areas, safe, compliant and efficient operation can be achieved within the regulatory framework. Enterprises can select corresponding intelligent storage cabinets according to their own gas consumption scale and scenarios, prevent risks in advance and consolidate the bottom line of gas cylinder safety management.
