Product Description Product Description Counter Flow Closed Circuit Loop Wet Air Evaporative Water Cooling Tower BNX-100 closed cooling tower Product ParametersTechnical Data: BNX-100 Closed Cooling TowerMODELCAPACITYNOMINAL FAN PUMPInlet/OutletDN(mm)DIMENSION(mm) LengthWidthHeight Can.(set)Motor(kw/set)Volumen(m3/h)Can.(set)Motor(kw/set)Volumen(m3/h) BNX-100100M3/H2465,00012.2100DN100125/DN125377018404450 Notes: Design condition: wet bulb temperature 28.2oC, inlett water temperature 37oC, outlet water temperature 32oC.Working principleFor BNX counter flow CLOSED COOLING TOWER, the coil will soaked fully by spraying water when the process fluid flows inside, meanwhile, the heat of working fluid will be transferred by wall of coil tube, and become saturated wet-hot vapor after mixed with water and air, then it will be discharged into atmosphere by fan, but water will be collected into water collection basin for recycled spraying, low water consumption. The spraying water temperature will be reduced during the recycling, and it flows in same direction to fresh air, and to cool the coil mainly by sensible heat conduction way. Our Advantages Advantage:Δ Excellent Heat Exchange PerformanceThe serie BHX production use the technical the combination of coils and PVC fill, which coil has heat exchange secondary with the same path of air and water, this effectively avoid the dry spot and scale formation, and improve the heat exchange performance.Δ Convenient MaintenanceHuge maintenance space makes it convenient to inspect the product. Technicians can enter the cooling tower during operation time.Realize non-stop maintenance.Δ Convenient Transportation and InstallationThe COOLING TOWER is designed to be standard upper body part and bottom body part, making it is able to be shipped separately and saves transportation and installation cost.Δ Slope Water Basin DesignThe design that the bottom of the sump is inclined to the end of the wastewater outlet and the design that the heat exchange layer of the PVC fill is suspended facilitate cleaning and the escape of dirty water and impurities.Detailed PhotosMain Components:1.Fan motors: Siemens, WEG, China brands..A. Top famous brand, with Siemens or WEG brand motors, high efficiency and low noise, special designed for evaporative condenser.B. Axial flow, induced draft type, PAG blades.C. Axial fans are mounted on top of evaporative condenser. Removable protective nets set in the side of the wind turbine.D. Motor is adopted with outdoor and waterproof, mechanical seal, protection IP55, insulation class F; E. Fan characteristic parameters meet design conditions, all blades with high quality process and reliable, smooth surface, each section transition uniform, no cracks, nicks, burrs; The gap of blade between the cooling evaporative condenser inner shell are same, and fans get through dynamic and static balance test and torque balance test. Fans rigorous static and dynamic balance need to be corrected before delivery, no chattering. F. Duct connection with fasteners made of galvanized steel or stainless steel; G. Direct-drive type fan, no need belt transmission, to save energy and improve drive efficiency, so the fan with following advantages: simple layout, low noise, no transmission loss, high efficiency, low friction components, easy maintenance etc.2. Coils: Galvanized steel, stainless steel..A. Each group of coil tubes is arranged with consistent slope, and the slope direction same with the water flow direction, east to facilitate water discharge from the pipe.B. Bracket for the coil is made by welded sectional material, and all processing technologies meet China National Metal Welding Workmanship Requirements & Standard. The cleaning and coating workmanship of the coil bracket surface same to the evaporative condenser bracket. C. Designed pressure is 2.0MPa, tubes in each group go through previewing and pressure test, and then to be assembled after getting through quality test. Test in the water with pressure 2.5MPa after assembled, to ensure its high performance in pressure resistance.D. Heat exchange coil is made of Galvanized steel or stainless steel.3.Spray water distribution systemA. Spraying Pumps: The spraying pump special designed for evaporative condenser, with Siemens or WEG brand motors. With high flow, low head, high efficiency, low noise, low power and energy saving advance. Pump motor with protection class IP55, insulation class F.B. Spraying Water Pipe: made of PVC, with flowing advantages: easy cold, high pressure resistance, anti-corrosion, and water resistant. All spraying manifolds are adopted removable type, easy to replace and clean. C. Nozzle: ABS material injection molding nozzle basket type -2-efficiency provided by the well-known brand suppliers; Adopt bigger hole diameter nozzles to prevent from blocking, which has a large flow, no clogging, water distribution uniformity, etc; in the design of the nozzle so that the different positions of the cloth water flow deviation <5% of the entire water distribution system can guarantee 70% to 130% of the rated flow of water distribution uniformity.E. Water level control system: the water level in spraying water tray is controlled by galvanized steel ball valve.4.Fill &Drift EliminatorA. The fill is one of the most important part of cooling tower, PVC heating exchange layer more effective to cool the water temperature by enlarge the evaporating surface.B. The PVC fill are produced by total automatic controlled high-speed blister forming machine in my workshop, better and more quick shaping. Meanwhile, the machine ensures the consistency of all fillers, being glued to entire body with glue rate no less than 95%, the compressive strength ≥300Kg/M2. The fillers have large heat exchanging surface and minimum air resistance, more effective.C. With special design, fill surface has good hydrophilicity, water absorptivity less than 0.015%. So more water film produced without splashing down. Water flowing rate less than 0.01%, more water saving, very suitable to Water stress region. Corrosion resistant, flame retardant, reinforced PVC packing, inflaming retarding oxygen index≥30. All raw material imported from South Asia to ensure the cooling tower fillers top quality and high performanceD. Drift eliminator: efficient water collection device is a standard part of evaporative condenser, which allows drift loss by circulating water less than 0.002%. Drift eliminator is made of corrosion-resistant modified PVC, Oxygen index of flame retardant≥30. Packet installed inside the unit, in order to access the internal water distribution system and other components. Packaging & ShippingPackaging & Shipping1) Standardized modular design, two body parts: upper body part and bottom body part;2) Shipped by one 20ft/40ft container,upper and bottom body parts shipped assembly and separately;3) Bottom body parts, will packed with plastic film to anti moisture, shipped assembly; 4) Upper body parts, will packed with plastic film to anti moisture, shipped assembly.

FAQFAQ(1)Your company is a manufacture or trading company?We are a leading cooling tower manufacturer with 38 years producing experience. The famous brand-"Heng An" is well known not only China but all over the world. The company is a large group company loacted in Weifang Citey of China.(2) What is the difference between a "counter flow" and a "cross flow" cooling tower?The crossflow or counterflow designation characterizes the orientation of the airflow within the heat-transfer media (fill) in the tower with respect to the direction of water flow.In counterflow towers air travels vertically upwards through the fill and makes intimate contact with water droplets falling down through the fill media. Hence the air and water travel in opposite directions.In crossflow cooling towers the air passes through the fill media in a horizontal direction, thus crossing the downward water flow. Counterflow towers are inherently more efficient than crossflow towers.(3) What is your Minimum Order Quantity(MOQ)? MOQ is 1set. Because our business for both wholesale and retail clients.(4) How do I get repair parts and how long does it take?Complete Parts Workshop, and can supply all parts,90% of Spare parts can be distributed to any place on the world within one week!
