Recently, a technical delegation from an Argentinian data center company visited Tester Technology for a comprehensive technical evaluation of its modular cable and pipe transit seal system. The inspection focused on core requirements for fire safety, electromagnetic compatibility, and space efficiency in data center scenarios. The customer ultimately confirmed that the product’s performance fully meets the demanding requirements of high-density computer rooms and high-voltage distribution rooms, and further deepened their strategic partnership.

This inspection not only represents a substantial advancement in the strategic cooperation between the two parties but also serves as an authoritative endorsement of China’s high-end manufacturing quality by the international industrial community.

A Field Trial: “Let the Product Speak for It”

In Tester’s production workshops and laboratories, the Argentinian customer team observed the entire product process, from raw material processing to finished product testing. Technicians demonstrated the system’s core features, including fire resistance, waterproofing, and vibration resistance, on-site:

Fire Protection

A-60 fire resistance certification (compliant with SOLAS standards); GB23864-3h (EI) certification, maintaining structural integrity and thermal insulation for three hours in a standard fire test.

Fully Sealed

IP68 waterproof rating effectively blocks water vapor and salt spray penetration, making it suitable for ocean shipping environments.

Electromagnetic Shielding

Shielding effectiveness reaches 42-63dB in the 14kHz-18GHz frequency range, effectively suppressing electromagnetic interference (EMI) and ensuring stable signal transmission for precision equipment.

Long-Term Reliability

The 316L stainless steel + EPDM rubber construction is designed for a 30-year lifespan.

The customer paused for a long time before the modular sealing system, expressing keen interest in its compact modular design and flexible adaptability. “This ‘peelable variable diameter’ structure supports ‘zero-demolition’ renovations, significantly reducing downtime for our data center room upgrades.”

The confidence of international recognition: Certifications, data, and scenario-based innovation
Why does Tester continue to be favored by international customers? The answer lies in three details:
1
The strength of authoritative certifications
Tester’s transit sealing system has been certified by the world’s five major classification societies: CCS (China), ABS (US), RS (Russia), BV (France), and RINA (Italy), as well as the Marine Equipment Directive (MED).
2
The efficiency revolution of modular design
Traditional sealing solutions require multiple cable glands to be spliced ​​together, but a single Tester system can replace 30 traditional components, saving 40% of installation space. Its “peelable variable diameter” core layer allows for plug-and-play integration with cables and pipes of varying sizes, increasing container pipeline sealing efficiency by over 50%. 1.
Lifecycle Cost Advantage
With its 30-year ultra-long lifespan and lifetime maintenance-free design, customers can reduce their overall cost of ownership by 30%. An Argentinian engineer admitted, “While international brands offer excellent products, Tester offers a solution that better meets our specific needs, with comparable performance.”

A Breakthrough in Domestic Manufacturing: From “Being Selected” to “Being Trusted”
After this inspection, the customer signed an expansion order on the spot and explicitly designated Tester as a strategic supplier. This choice reflects the continued breakthroughs made by Chinese manufacturing in the high-end industrial sector:

Technological Independence: Tester boasts a R&D team led by three experts receiving special allowances from the State Council. The team has established a joint laboratory with Shenzhen University to master key technologies such as high-temperature materials and electromagnetic compatibility.

Lean Quality Control: Key process machining errors are controlled to ±0.02mm, and the product has passed rigorous testing for airtightness, hydraulic blasting, and vibration fatigue.

Localized Service: The technical team is deeply involved in customer-specific design, providing full-process support from solution customization to installation guidance.

“Test has proven that Chinese brands can not only meet international standards but also address our real pain points with greater agility and affordability,” concluded a customer technical representative.

From Argentina to Southeast Asia, from data centers to energy platforms, Test’s transit seals are reshaping international customers’ perception of “Made in China” with their solid performance and attentive service.
This is not only a source of pride for Test, but also a microcosm of China’s high-end manufacturing industry—earning trust through quality and defining standards through innovation. As domestic brands on the global stage transition from “followers” to “parallel competitors,” we witness not only the growth of a single company but the rise of an entire industry.
