GOM Series Steel Open Cooling Towers

GOM Series cross flow steel open cooling towers are generally of higher capacities, can work in series as a group for large projects. Enclosure made in special alloy coated steel or stainless steel. GOM towers are of optimized firm structure, high efficiency, low drift rate, and anti blocking. The towers dimensions can be customized to suit standard containers or particular project conditions. GOM towers are widely applied in different fields, to cool circulating water for Melting Furnaces, Induction Heaters, Metal Parts Production Lines, Hydraulic Stations, Power Generators, and other utilities requiring massive cooling water, but not highly demanding on water quality. Initial invest in open towers is lower, but water consumption rate is higher comparing to closed loop cooling towers.

STRUCTURE & CASING

STRUCTURE & CASING

The standard enclosure is made of the latest type of Highly Corrosion-resistant coated steel sheet with a coating composition of Zn+Al(11%)+Mg(3%), and a trace amount of silicon, originally imported from Nippon Steel or Posco. The panels are sheared and folded precisely in whole cold machining process, then densely bolted and sealed for water tightness, with sufficient reinforcing bars, preventing deforming during hoisting process in fields. Each tower is completed with maintenance access and doors of maximized size, for internal inspection convenience. 




NON-DIRECT DRIVE AXIAL FANS

NON-DIRECT DRIVE AXIAL FANS

A part of open loop series adopt non-direct drive axial fans, fitted with al-alloy airfoil blades perfectly balanced and coupled with gear box or belts with spead reducer, to a weather proof TEFC three-phases electric motor. The fan casing is a galvanized steel cylinder to draw the air vertically and avoid the risk of recirculation. The tip speed of the impeller is limited to keep the noise level within acceptable limits.  






WET DECK FILL

                                                                                                                                                                                                                      

WET DECK FILL

The fills are formed in flame-retardant PVC sheets with a special shape design of herringbone surface, to distribute water evenly over the entire fill area for maximal thermal performance, can be integrated with air inlet louvers and drift eliminators. For medium fouled water, fill types with enlarged grids are available to reduce the chances of blocks. All the raw materials are of virgin grade from approved suppliers, with long service life in tough environment.


 

DRIFT ELIMINATOR

DRIFT ELIMINATOR

Cellular Drift Eliminators are specifically designed to achieve maximum drift removal. With significantly lower pressure drop. The modules are constructed of a series of sinusoidal-shaped, corrugated PVC sheets that are mechanically assembled to mating sinusoidal structural waves, forming closed cells. These cells force the drift droplets being carried in the leaving airstream to make three distinct changes in direction. When the air is forced to change direction, the inertia of the water droplets keeps them moving in a straight line, causing them to impact the wall of the drift eliminator and drain back into the wet section of the tower.





AIR INLET LOUVERS


AIR INLELOUVERS

Cellular air Inlet louvers with advanced design improve air flow into the cooling tower, keep out debris, eliminate water splash-out, which otherwise can cause icing, near-site water damage,and unnecessary water loss. The deign restrict the amount of sunlight into the cooling tower to impede algae growth, reduce noise from the tower, and improve the tower's appearance.



       

SPRAY NOZZLES FOR OPEN TOWERS


SPRAY NOZZLES FOR OPEN TOWERS

The Spiral Target Nozzles used for GOM Series open towers, injection molded in polypropylene unit consisting of two parts, main body with integral target diffuser and a snap-on insert or orifice cap. The nozzles installed in bottom of the hot water distribution basins, to eliminate water diffusion decks below the hot water basins, provide full water coverage of the fills by gravity flow, removable and replaceable but of long service life. Sizes and variety depends on the tower size, water flow rate and water quality.





FLOAT VALVE

FLOAT VALVE

Heavy duty floating valve, made in stainless steel, floating ball in engineering plastic or stainless steel, with long service life. Water level ad justable.   

 



ANTI-EDDY FILTER


ANTI-EDDY FILTER

Effectively filting the sundries, with anti-eddy arrangement, preventing air bubbles sucked into the pumps, punched in the same material as the enclosure, highly corrossion resistant. 







FASTENERS


FASTENERS

GOM General Outline


Working Thoery

GOM Working Theory

WORKING THEORY

In GOM open cooling towers, the hot water is inlet to the water distribution basin on the top of the tower firstly, and spread onto the extensive surface of the wet deck fills after flowing through the spreading holes by gravity. Meanwhile the dry cool air is inlet through the side louvers of the tower, passing the fills across the water falls. During this process, a part of water is evaporated, with heat removed. The wet hot air is induced draught out of the tower into the atmosphere by the fans on the top, while the cooled water is collected back to the bottom collection basin with the eliminator, flowing back to the equipment requiring cooling water.
