In the chemical, pharmaceutical, scientific research and industrial manufacturing sectors, the safe storage of flammable liquids has always been a top priority in enterprise safety management. An accidental fire can not only cause huge property losses, but also endanger personal safety and damage the ecological environment. How to ensure that safety storage cabinets for flammable liquids can hold their ground under extreme fire conditions and buy precious time for personnel evacuation and fire fighting is not only a mandatory regulatory requirement, but also a core concern of every responsible enterprise.

Recently, the industrial-series flammable liquid safety storage cabinet (Model: DeSUN-FRC-TYP90) independently developed by Shanghai DeSUN ECOTECH CO., Ltd. (hereinafter referred to as "DeSUN ECOTECH") has successfully passed the strict fire resistance test conducted by SGS, the world’s authoritative testing and certification body. The test was carried out in accordance with the latest EU standard EN 14470-1:2023, and the product was finally awarded the highest fire resistance rating under this standard: Type 90 (90-minute type). This milestone achievement marks that DeSUN ECOTECH’s technical strength in the field of hazardous chemical safety storage has reached the international leading level, and sets a new benchmark for the quality of domestic flammable liquid safety storage cabinets.

Authoritative Verification: Rigorous SGS Test Demonstrates Solid Technical Strength with Hard Data

SGS is the world’s leading inspection, verification, testing and certification body, whose test reports are recognized by numerous authoritative institutions worldwide. This test was strictly implemented in accordance with the 2023 revised EU standard EN 14470-1 and conducted on June 16, 2026. During the test, the safety cabinet was placed in a test furnace simulating a real fire and heated continuously for 90 minutes following the standard time-temperature curve specified in EN 1363-1:2020. The average temperature inside the furnace was precisely controlled to strictly fit the standard curve, ensuring the authenticity and authority of the simulated environment.

Under such harsh conditions, the performance of DeSUN ECOTECH’s flammable liquid safety storage cabinet was impressive. The standard requires that the temperature rise at any measuring point inside the cabinet shall not exceed 180 K (Kelvin). After 90 minutes of exposure to intense fire, the maximum temperature rise inside the cabinet was only 146.5 K. Calculated based on the ambient temperature of 26℃ at the start of the test, the maximum internal temperature of the cabinet was approximately 172.5℃, far below the upper limit of about 206℃ allowed by the standard, with sufficient temperature rise margin and excellent thermal insulation performance.

Post-test inspection showed that although the cabinet body turned grayish white and the cabinet door was slightly deformed, there was no obvious abnormality inside except for minor discoloration. The cabinet door did not burst open and retained its locking function, with the overall structural integrity well maintained. This means that even in an extreme fire environment with an external temperature exceeding 900℃, the storage cabinet can still keep the internal temperature within a safe range and provide up to 90 minutes of effective protection for flammable liquids.

Technology-Driven Excellence: Meticulous Design Builds a Reliable Safety Barrier

Behind this outstanding result is DeSUN ECOTECH’s unremitting pursuit of technological innovation. Founded in 2018 as a national high-tech enterprise, DeSUN ECOTECH has always adhered to the mission of "realizing industrial safety through technology". The company focuses on providing safe, standardized and intelligent integrated storage solutions for hazardous waste, hazardous chemicals and lithium batteries.

The flammable liquid safety storage cabinet that passed the test adopts high-strength explosion-proof steel and a multi-layer fireproof structure, filled with high-efficiency fire insulation material in the middle. This structure not only ensures sufficient structural strength of the cabinet at high temperatures, but also effectively blocks heat transfer to the interior, which is the core technology enabling it to pass the 90-minute fire resistance test. Meanwhile, the cabinet has overall dimensions of 663mm × 1231mm × 458mm and a net weight of about 233kg. It is solid and stable, and can meet the installation requirements of most laboratories and production workshops.

DeSUN ECOTECH not only strives for excellence in product R&D, but also actively participates in the formulation of industry standards. As one of the key drafting units, the company has participated in the formulation of the group standard Safety Technical Requirements for Hazardous Chemical Storage Cabinets, which fully demonstrates its technology-leading position in the industry. Passing the SGS Type 90 test is the inevitable result of its long-term adherence to high standards and strict requirements.

Compliance Support: Meeting Stringent Regulations to Boost Enterprise Safety Upgrade

EN 14470-1:2023 is the latest standard for hazardous chemical storage cabinets formulated by the European Committee for Standardization. Compared with the old version, the new standard has significantly raised the test requirements for fire resistance duration, raising the minimum fire resistance time from 15 minutes to 30 minutes. Against this background, the flammable liquid safety storage cabinet’s one-time pass of the highest-level 90-minute test not only proves the excellent product quality, but also means that enterprises using this product can easily meet the latest EU regulatory requirements. This provides strong support for product export, high-end market access, and domestic high-standard safety construction.

For end users, choosing DeSUN ECOTECH’s SGS-certified flammable liquid safety storage cabinet (Type 90) delivers significant value: first, worry-free compliance, as it meets the strictest international standards and reduces trade barriers; second, reliable safety guarantee, as the 90-minute ultra-long fire resistance time provides a golden window for personnel escape and fire rescue; third, controllable risks, as it effectively curbs the escalation of fire accidents and protects the safety of personnel, property and the environment.

True quality stands the test of extreme fire. DeSUN ECOTECH’s flammable liquid safety storage cabinet has successfully passed the rigorous 90-minute SGS test with an excellent temperature rise performance of 146.5 K. This is not only the best proof of its product strength, but also a solid fulfillment of its safety commitment to customers. In the future, DeSUN ECOTECH will continue to drive safety upgrading through scientific and technological innovation, and contribute Chinese wisdom and strength to global hazardous chemical safety management.
