DBNL3J-70 Cross-Flow Cooling Tower | Anti-Corrosion FRP Exporter for Power Plants & HVAC

As a premier Chinese exporter specializing in factory-direct FRP cooling solutions, our DBNL3J-70 cross-flow cooling tower is engineered to solve the critical challenge of thermal management in high-capacity industrial recirculating water systems, particularly for thermal power plants and large-scale HVAC central air-conditioning projects. Unlike standard models, this unit features a heavy-duty corrosion-resistant FRP shell and an optimized fill design that sustains thermal performance even in dusty or saline coastal environments, ensuring a 12-15°C temperature drop under 70 nominal tons of load. By eliminating intermediary markups, we offer international buyers a transparent, bulk-export pricing structure coupled with rigorous workshop performance testing (thermal rating verification) and customized voltage options for global compatibility, positioning your project for a 20% reduction in long-term maintenance costs while meeting strict environmental discharge noise standards.

Product Advantages

Structural Integrity with Maritime-Grade FRP Shell
The DBNL3J-70 is fabricated using a flame-retardant, UV-stabilized FRP laminate that incorporates an additional gel-coat thickness of 0.5mm – exceeding standard industry practice. This shell formulation is specifically engineered to withstand not only internal chemical attack from pH-fluctuating recirculated water but also external saline mist, airborne fly ash, and industrial fumes commonly found in coastal power stations and steel sintering plants. The result is zero surface chalking or micro-cracking after 8–10 years of outdoor exposure, eliminating the need for costly periodic repainting or panel patching that plagues metallic towers.

Gravity-Flow Water Distribution for Unmatched Pumping Economy
Unlike forced-spray nozzles that require higher pump head pressure, the DBNL3J-70 employs a large-basin, gravity-fed distribution system with anti-clogging orifices (25mm diameter). This design reduces the required pumping head by approximately 2.5–3.0 meters compared to conventional counter-flow equivalents, directly translating to 12–15% lower annual electricity consumption on your circulating pump set. Furthermore, the open-basin structure allows for rapid visual inspection of water flow even during full-load operation, enabling your shift operators to spot uneven distribution or debris accumulation within seconds without any tools.

Drift Eliminator with Sub-0.001% Water Loss Rate
Our proprietary three-pass zig-zag drift eliminators, manufactured from high-impact PVC, are recessed into the tower exit duct to maximize capture surface area without increasing pressure drop. Independently tested at 110% of design air velocity, these eliminators guarantee water carryover below 0.001% of the recirculation rate – a critical metric for plants operating under strict water consumption permits or those using expensive demineralized make-up water. This feature alone can save up to 150–200 cubic meters of water annually per 70-ton unit, directly supporting your corporate ESG (Environmental, Social, and Governance) reporting targets.
