Strength Certification! JLCT Cooling Towers Pass CTI Annual Test in One Go!Interpretation of the Industry Value of CTI Certification
1. Definition of CTI Certification
CTI (Cooling Technology Institute) is the most influential authoritative institution in the global cooling technology field. Its thermal performance certification standard for cooling towers (CTI STD-201) aims to ensure that the actual cooling capacity of cooling towers is fully consistent with the data published by manufacturers.
What CTI certification verifies is not whether a manufacturer can produce a cooling tower with excellent performance, but whether every unit in mass production can stably deliver the rated performance commitment.
2. CTI Certification: The “Touchstone” for Thermal Performance in the Cooling Tower Industry
After a cooling tower passes CTI certification, the cooling tower models retested each year must be different, and annual retesting is required to continuously verify cooling capacity.
· Core assessment dimensions: heat exchange performance is consistent across different production batches and different manufacturing cycles; selection sample parameters, laboratory measured data, and on-site operating performance are fully consistent.
· Value of annual testing: annual retesting, with the entire series passing in one go, represents that the company’s entire R&D, production, and quality control system is stable and reliable over the long term. It is a core access qualification for high-end projects, export projects, and precision process procurement.
The fact that JLCT cooling towers passed the CTI annual test in one go across the entire series not only proves that product performance meets standards, but also serves as strong verification of Zhejiang Jinling’s more than 20 years of stable manufacturing capability and comprehensive authoritative endorsement of its continuous technological iteration capability.
III. Core Results of This Certification: Strength Witnessed
Recently, Zhejiang Jinling Refrigeration Engineering Co., Ltd. welcomed its annual CTI annual test. All four major series of cooling towers—JNT, JFT, JNC, and JFC—passed the test and certification in one go!
As one of the first 14 cooling tower manufacturers in the world to obtain CTI certification, Zhejiang Jinling has passed US CTI certification testing for 21 consecutive years. Behind this record is decades of unremitting technological accumulation and commitment to quality.
Two Highlights of Authoritative Certification
1. Full Product Matrix Coverage, All Cooling Performance Meets Standards
The certified models cover four mainstream technical routes: crossflow open-circuit, counterflow open-circuit, crossflow closed-circuit, and counterflow closed-circuit. They meet full-scenario needs including large-scale industrial centralized cooling, precision clean processes, installation in confined sites, and low-temperature severe cold environments, fully covering the commercial and high-end industrial cooling markets.
2. Self-built Test Facility Officially Recognized, R&D and Testing Closed Loop Independently Controllable
This CTI retest was conducted at the cooling tower thermal performance test facility established according to CTI standards at Zhejiang Jinling headquarters, with internationally advanced levels. From product R&D to authoritative certification, an in-system closed loop is achieved, with authoritative, traceable, and verifiable data throughout the process.
The deeper significance of this certification: This not only reflects the performance reliability of the equipment, but is also the best answer demonstrating that Zhejiang Jinling’s entire system—from structural design, self-development of core components, complete machine assembly, to factory calibration—possesses large-scale manufacturing capability to stably output international-standard cooling tower products.
