Import Brazed Heat Exchanger — Buy in Bulk from Supplier in China

New Roc Industrial Ltd., based in Tianjin, China, manufactures brazed heat exchangers using vacuum brazing technology that joins metal plates at elevated temperature without mechanical fasteners or elastomer seals. All-stainless construction with copper or nickel braze alloy yields a pressure-boundary capable of operating up to 45 bar and 250°C according to the supplier's stated ratings. The plate surface pattern generates turbulent flow even at low Reynolds numbers, achieving heat transfer rates substantially above equivalent shell-and-tube units while occupying a fraction of the footprint. Connection options appear flexible, with standard and customised models available to match hydraulic and spatial constraints.

Plate materials from New Roc Industrial Ltd. include stainless steel, aluminium, or titanium, with grade selection driven by fluid compatibility and corrosion resistance requirements. Stainless steel 316L dominates water and glycol applications, while titanium addresses seawater or chloride-rich environments. The vacuum brazing process eliminates oxidation during joining, producing cleaner fillets and more consistent joint strength than atmospheric methods. Plate thickness in this product category typically falls between 0.3 mm and 0.6 mm, with deeper corrugations increasing turbulence but also pressure drop. The compact structure reduces installation space and supporting structure costs, with unit weight approximately 20-30% of an equivalent shell-and-tube exchanger. Scaling is mitigated by higher fluid velocity, though this assumes proper system design with adequate pump capacity.

Target industries span metallurgy, food processing, light industry, chemical production, refrigeration, and heating and ventilation. Buyers include plant engineers specifying process cooling, HVAC contractors, refrigeration system integrators, and maintenance organisations retrofitting older shell-and-tube installations. New Roc Industrial Ltd. operates from a harbour-tier verified profile, though no response metrics are available to assess quotation speed. The supplier promotes standard and configurable models without publishing minimum order quantities or standard lead times. Prospective buyers should contact New Roc Industrial Ltd. directly to confirm current production capacity, certification scope, and sample availability before tendering projects.

New Roc Industrial Ltd. is located at Fenghe Xinyuan, Xi Shi Da Jie, Nankai District, Tianjin, 300102, China. The supplier holds harbour-tier verification, indicating baseline profile confirmation without extended audit or transaction history disclosure. No response rate or average response time is recorded, suggesting buyers may experience delays in initial contact and should plan procurement timelines accordingly. The company profile does not state founding year, factory floor area, number of employees, or annual production volume, leaving scale and experience level unverified.

The listing from New Roc Industrial Ltd. emphasises vacuum brazing technology, multi-material plate options, and compactness advantages over shell-and-tube alternatives. The supplier claims suitability for diverse industrial sectors and offers both standard and customised configurations. No named quality certifications, patent information, or major client references appear in the available data. Buyers are encouraged to request factory audit reports, ISO quality system certificates, and performance test data for comparable installations before advancing to trial orders.
