CE Certification Mechanical Draught Cooling Tower Company & Companies

Our CE declaration documents full compliance with the European Machinery Directive (2006/42/EC) for rotating assemblies and dynamic fan stacks, the Low Voltage Directive (2014/35/EU) for electric motor drive systems and thermal switches, and the Electromagnetic Compatibility (EMC) Directive (2014/30/EU) for fan motor drives and PLC sensor controllers. For closed-circuit towers featuring pressurized fluid heat exchangers, we certify compliance with the Pressure Equipment Directive (PED 2014/68/EU).

Induced draught towers locate the axial fan at the top exit orifice. Air enters through bottom or side louvers, flows upward through the fill media, and is discharged vertically at high velocities (9–12 m/s). This upward expulsion prevents warm, humid discharge air from recirculating back into the air inlets, maximizing thermal performance. Forced draught towers place the fan blower at the bottom air intake, pushing dry ambient air up through the fill. While forced draught units offer convenient ground-level motor servicing, they require more fan horsepower to overcome discharge velocity losses and are more prone to recirculation in confined enclosures.

Open counterflow towers allow direct evaporative contact between process water and ambient air, offering lower capital cost and high efficiency for general commercial HVAC chillers. However, process water in open towers absorbs airborne contaminants, requiring filtration and chemical biocide treatment. Closed-circuit cooling towers isolate the process fluid inside sealed, seamless serpentine coils (copper, SUS304, or galvanized carbon steel). They are critical when protecting high-value equipment—such as induction furnace thyristors, cleanroom chillers, petrochemical process loops, and data center water-side economizers—from particulate fouling, mineral scaling, and corrosion.

Our mechanical draught cooling towers integrate high-efficiency cellular PVC drift eliminators designed in accordance with Eurovent and VDI 2047-2 standards. These eliminators utilize three-pass aerodynamic turning geometry that captures entrained water droplets from the upward airstream while introducing minimal static pressure drop. The certified drift loss rate is less than 0.001% of total circulating water volume. Furthermore, our basins feature sloped, self-draining bottoms and non-stagnant suction sump designs that facilitate rapid flushing, biocide dispersion, and routine cleaning.

Depending on ambient chloride levels and fluid chemistry, we fabricate cooling tower structural skeletons using pultruded fiberglass reinforced polyester (FRP) with ASTM E-84 Class 1 fire-retardant resins, heavy hot-dip galvanized steel (HDG Z600 coating), or heavy-gauge stainless steel (SUS304 or SUS316). Hardware fasteners are offered in Grade 304, 316, or Silicon Bronze. Casing panels are molded from gel-coated FRP with UV inhibitors to withstand intense maritime solar radiation and corrosive atmospheric conditions.

Yes. Situated in Dezhou, Shandong with convenient port logistics to Qingdao and Tianjin, we regularly host and coordinate third-party pre-shipment inspections with SGS, Bureau Veritas (BV), TÜV Rheinland, and client-appointed engineering inspectors. Inspection scopes routinely include dynamic balance reports, welding non-destructive testing (NDT), hydrostatic coil testing, motor run trials, galvanized coating thickness checks, and full container stuffing inspections.

Standard modular open counterflow towers up to 500 nominal tons typically ship in 15 to 25 business days. Heavy custom closed-circuit towers or large multi-cell FRP industrial towers take approximately 30 to 45 days, inclusive of customized drawing sign-offs and factory FAT testing. Equipment can be shipped fully assembled in 40HQ high-cube containers (for modular sizes) or knocked down (CKD/SKD) with numbered, pre-drilled structural assemblies for compact sea freight and straightforward site erection.
