For industrial operations battling sustained high-temperature circulating water—from refinery crackers to HVAC central plants—the DBNL3J-70 FRP cooling tower delivers a calibrated balance between thermal exchange efficiency and structural longevity. Engineered with a corrosion-resistant glass-fiber shell and a low-clogging cross-flow fill system, this 70-ton nominal capacity unit maintains approach temperatures within ±2°C even under 35°C wet-bulb conditions. As a manufacturing-origin exporter with in-house mold design and ASTM-standard galvanized steel supports, we provide direct retrofit solutions for existing basins, complete with drift eliminators that reduce water loss to under 0.001% of circulation flow—ensuring both process stability and municipal water quota compliance for heavy industries across Southeast Asia and the Middle East.

Product Advantages
Gravity-Fed Cross-Flow Design Slashes Pumping Energy by 18%
Unlike forced-spray or counter-flow towers that rely on high-pressure nozzles, the DBNL3J-70 employs a natural gravity-distribution basin across its entire fill surface. This design reduces the required pump head by nearly one-fifth, translating directly into lower kWh consumption per ton of circulated water. For a 24/7 industrial plant, this single feature can cut annual electricity bills by thousands of dollars while extending the service life of your water pumps due to reduced cavitation and backpressure stress.
Anti-Corrosion FRP Shell Engineered for Harsh Chemical & Coastal Atmospheres
The casing is compression-molded from flame-retardant, UV-stabilized glass-fiber reinforced polyester, with a gel-coat thickness exceeding 0.5mm. This provides exceptional resistance to hydrogen sulfide, ammonia, and salt-mist corrosion — common killers in petrochemical refineries and seaside power stations. Unlike mild steel towers that require frequent repainting or stainless steel variants with prohibitive costs, this FRP body remains structurally intact for over a decade with minimal surface maintenance, even in 85% relative humidity environments.
Precision-Tuned Fill Geometry Maximizes Heat Exchange Under High Wet-Bulb Conditions
The internal PVC fill features a sine-wave fluted pattern with optimized flute angles specifically calibrated for the DBNL3J-70's 70-ton nominal capacity. This geometry extends water retention time without increasing drag, achieving a cooling approach temperature within ±2°C of the ambient wet-bulb reading — even when ambient conditions hit 35°C. For plant operators, this means stable condenser pressures, fewer production halts due to overtemperature alarms, and consistent process quality across summer peak loads.
