What materials are used for the coil?

Commonly stainless steel 304/316L, copper tube, and galvanized steel pipe.

What are the main applications?

Induction melting, compressor, injection molding, chiller, metallurgy, electric power, chemical industry, HVAC.

Yes. We customize according to cooling capacity, flow rate, inlet/outlet temperature, voltage and working environment.

What about water consumption?

It only consumes water by evaporation and blowdown, saving about 30%-50% water compared with open cooling towers.

AI-Powered supplier vetting

SummaryThe supplier is a combined manufacturing and service company offering cooling equipment and related products. It demonstrates broad customization capability, OEM service for well-known brands, stated quality and environmental management certifications, and relationships with several internationally recognized and domestic customers. Its production information covers cooling towers, evaporative condensers, air-cooled heat exchangers, and PVC film, supported by cutting and molding equipment. However, several management and innovation records are incomplete: finished-product inspections, supplier assessments, and corrective actions have procedures or instructions but lack written records; no new products were reported in the past year, and no ODM, SDK, 3D design, or dedicated professional technical supplier capability was indicated. Overseas support is provided through agents or branches and includes training and debugging, but no overseas warehouse or showroom is available.

CertificationsThe supplier states that it has passed ISO9001 quality management, ISO14001 environmental management, and OHSAS18001 occupational health and safety management system certifications. It also reports inventions and patents, providing explicit evidence of multiple management-system certifications.

After-Sales capabilityThe supplier states that it has an after-sales service system and offers overseas training and debugging through overseas agents or branches. It has participated in the China Refrigeration Show, but it has no overseas warehouse or showroom and lists zero countries for overseas service coverage, so the geographic breadth of support is limited or unclear.

Production capacityThe supplier lists production capacity for closed cooling towers, evaporative condensers, air-cooled heat exchangers, open cooling towers, and PVC film, with cutting and molding machines as combined facilities. It also states that manufacturing processes and testing methods are established, although finished-product inspection instructions have no written records, which weakens documented production-control evidence.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its description also states that complex products are tailored to specific customer requirements and that design solutions are provided, directly supporting strong customization capability.

Client casesThe supplier identifies strategic partnerships with Caterpillar WINGFAN, NRF, and ADRAD, along with domestic customers including CNNC, Yili, Shenmu Longhua, and CASIC. These named relationships provide explicit evidence of customer experience across internationally recognized and domestic organizations.

Product Q&A

Q:What is a counterflow closed cooling tower?

It is a closed cooling tower where air flows upward and spray water flows downward, forming a countercurrent heat exchange with the coil inside.

Q:What is the working principle?

Hot fluid runs inside the closed coil. Spray water and air cool the coil surface through evaporation and convection, without direct contact between fluid and air.

Q:What are the advantages over open cooling towers?

The cooling medium is fully enclosed, clean, non-polluting, and less scaling. It saves water and ensures stable long-term operation.

Q:What media can be cooled?

Circulating water, hydraulic oil, glycol solution, chemical fluid, induction cooling water, etc.

Q:What is the difference between counterflow and crossflow?

Counterflow: air and water flow in opposite directions, higher heat exchange efficiency, smaller footprint. Crossflow: air flows horizontally, lower noise, easier maintenance.
