Specializing in the DBNL3J-60 model, our factory-direct FRP cooling tower export solution targets 60 cubic meters per hour recirculating systems commonly found in air compressor intercoolers, hydraulic oil coolers, and injection molding machine barrel cooling lines. This round counterflow design features a heavy-duty FRP shell with UV inhibitor for outdoor installations, upgraded high-efficiency PVC drift eliminators to reduce water loss below 0.001%, and a maintenance-friendly belt-driven fan that accommodates both 380V/50Hz and 460V/60Hz motors for global compatibility. Beyond new unit sales, we serve as a reliable aftermarket supplier offering direct-replacement fill packs, spray nozzles, and gearboxes for existing DBNL3J towers, helping plant owners extend equipment life while cutting energy consumption by 8–12% through retrofit kits. With dedicated export documentation, wooden crating for sea freight, and on-site installation guidance via video calls, we empower overseas contractors and factory maintenance teams to procure premium-grade cooling towers without minimum order quantity constraints, ensuring cost-effective operation for tropical and temperate climates alike.

Product Advantages
Structural Integrity with Marine-Grade FRP Laminate
Unlike ordinary industrial polyester resins, our cooling tower shell employs a flame-retardant, UV-stabilized isophthalic FRP laminate with a gel-coat thickness of 0.5 mm. This formulation resists micro-cracking under continuous thermal cycling (from 10°C to 55°C ambient swings) and maintains flexural strength above 180 MPa for over 15 years. We deliberately avoid calcium-filled cheap layers—every panel passes a 2,000-hour salt-spray test, making our towers equally reliable for coastal LNG terminals and inland steel mill recirculating systems.
Drift Elimination and Water Conservation Engineering
The "collecting type" designation is not cosmetic—it integrates a three-stage drift eliminator with a sinusoidal chevron profile, positioned just 300 mm above the air inlet. This geometry reduces water carryover to below 0.001% of circulating flow, even at 120% of design air velocity. For a 500 m³/h system, this translates to saving approximately 4.5 tons of make-up water per month compared to conventional eliminator designs. Additionally, the basin's built-in weir and equalizing port allow full drainage without pump cavitation, a feature often overlooked but critical for winter shutdown in temperate climates.
Acoustic Performance Without Compromising Thermal Duty
Our low-noise claim is validated by third-party tests at 8-meter distance: 73.5 dB(A) for standard fan configuration and 69.2 dB(A) with the optional high-efficiency six-blade aerodynamic rotor. More importantly, we achieve this noise floor without reducing the fill volume or increasing the tower footprint. By optimizing the fan stack angle and using a direct-drive TEFC motor with dynamically balanced hubs, we suppress both broadband noise and discrete tonal peaks at blade-passing frequencies—a decisive advantage for projects requiring night-time operation near residential zones or hospital intensive-care wings.
