WCN cooling tower WCN Cooling Towers are the result of extensive research, development and testing. The high-performance, reliable and cost-effective components, designed at state of the art technology results in an excellent cooling tower line you can rely on.

WCN Cooling Towers are designed according international industrial standards. The structure is lightweight and extremely rigid. The tower is equipped standard with an industrial low noise axial fan. The drive sets can be chosen from V-belt drive, direct gear drive or angled gear drive with the motor outside the air stream. Structural materials used are SST 304 and FRP pultrusions, with PVC or ABS fills and eliminators. The water is distributed with tangential non-clogging nozzles. The installation is fast and easy. WCN towers do meet a field performance test according CTI STD 105 or DIN 1947 field test protocol.

WCN Series Cooling Towers are specially designed for Air-Conditioning and Industrial applications. We warrant the thermal performances and the maximum service life of our products.

WCN-Series:
The WCN Series are highly reliable and efficient cooling tower products. The WCN Series are compact modular Counter Flow Top Discharge Cooling towers, with a reach from 150 to 1800 Tons of Water (m3/h), or 660 to 8000 GMP. The integrated fan and drive unit assures ascetic design and optimal performance of the cooling tower units. The cost-effective construction minimizes installation cost and reduces down time due to efficient engineering. Modern materials make our products weight less.

WCN cooling tower designReliable performance:
Every WCN cooling tower supplied achieves the required temperatures at the critical climatological conditions, stated in the design conditions. WACON follows the common design criteria for evaporative cooling. WACON produces high efficient infill in PVC and PP brand name infill, tested by popular institutes in Asia, Europe and the USA. Therefore WACON Cooling Tower products provide always the coldest water possible.
WACON assures that the published capacities and operating data are reliable. Any on-site thermal performance testing (e.g. CTI 105 or DIN 1947) can be executed.

Energy efficient:
Due to the most efficient air to water ratio, in combination with the honeycomb lined infill and low-noise high performance axial fans we generate high air volumes. The cylindrical body and the bell shaped fan exhaust create a minimum pressure drop where we can operate a lower motor power and a dramatically increased tower performance.

Noise:
Due to the well-engineered efficient tomahawk fan we move large air volumes at low fan speed. This results in lower noise levels, which meet in general the specifications required. Durability. The application of Fiberglass Reinforced Plastics in combination with galvanized steel or stainless steel parts makes this tower extremely durable. Our products withstand UV radiation, chemical erosion and thermal shocks.

Modularity:
The WCN Cooling Tower Series are easy to install and easy to expand in capacity by adding extra towers. A number of smaller units mean safer operations at shut down, small circuit breakers and motors instead of single large piece of equipment.

Features:
The motor, drive unit, fan, infill and water distribution system are easy accessible.

Drive options:

• V-belt drive

Motor:
The motor we will chose a motor based on client's specification and power rating. Insulation will be a minimum of IP 55, the enclosure F5 with enclosed ball bearings and a service factor of > 1.12. For direct drive fans, the motor will be installed on a rigid motor support. If driven by a V-belt reducer, the complete drive set is installed on a rigid motor support with V-belt spanner slide.

Fan:
Our highly efficient axial propeller fan will be capable of heavy duty and statically balanced. The fans are an industrial type Class -A- brand to ensure capacity. The fans are manufactured of rolled plate aluminum and a casted aluminum hub. The aluminum hub has a key lock or taper-lock for easy repairs and so each fan blade can be individually adjusted. The fan will be installed in a closely fitted cone with a venturi air inlet for maximum fan efficiency. If required, the fan cone shall be covered with a heavy gauge steel wire fan guard to improve safety.
