GZM Series Evaporative Condenser

GZM Series Evaporative Condensers are made in the same types of materials as GHM and GTM Series, and of similar working theory as a type of Evaporative Coolers, but designed dedicatedly to cool process fluids of refrigerant, of which the forms are changed during the process.

Configurations

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 excellent water tightness, with sufficient reinforcing bars for a firmest structure. Condensing coils section is firmly supported by frame made in stainless steel, or H.D.G steel plated entirely after welding.





EVAPORATIVE COOLING COILS

CONDENSING COILS

The condensing coils are of patented design, with low air resistance but high heat transfer efficiency,suitable to work with larger amount of spray water. Standard coils tube made in stainless steel 304/316, or red copper and titanium ally on options.  Different wall thickness can be met on request. Each coil is tested under continuous nitrogen gas pressure of 30 bar for 24 hours,ensure no leaking or weak point. 







DIRECT-DRIVE AXIAL FANS


DIRECT-DRIVE AXIAL FANS

The standard closed loop series adopt direct-drive axial fans, fitted with resin or al-alloy airfoil blades perfectly balanced and coupled 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.





SPRAY PUMPSPRAY PUMP

Standard spray pumps are of GZ horizontal centrifugal series from GSD brand, with motor of brand TECO, specially designed for evaporative cooling equipments, of generally large flow rate but low pumping head. The selected pumps are of dynamic-static balance, with shaft as an extended section from the motor, for most reliable concentricity. With first grade bearings, the pumps runat minimized vibration and low noise. Mechanicseals avoids abrasion to shaft, no leakage in long term service life. Overload protected on any point of the performance curve, not exceeding the rated power during the whole working period. Enclosure materials and installation arrangement can be optional and modified to suit different projects requirements.



 

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 PIPE

SPRAY PIPE

Spray Pipes made in U-PVC from FPC, of high mechanical strength and long service life, holding pressure1.0 Mpa, accessible to inspect and maintain from outside of the tower, convenient to check with when running fully, completed with buttonholes for quick and tight installations of spray nozzles.





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

Fastners of leading brands, standard materials in steel dacromet treated, stainless steel on options. Intensity of fastners is higher than average.

GZM General Outline




Working Thoery


GZM Working Theory

WORKING THOERY 

GZM Condenser utilizes the evaporation of partial spray water, to absorb the heat from the flowing gaseous refrigerant of high temperature inside the condensing coils, and cool the refrigerant from gaseous state to liquid form. In a complete evaporative cooling system, compressor discharges high pressure evaporated refrigerant in gas form, which passes through the heat exchange coils of evaporative condenser, and exchanges heat with spray water outside the heat exchange coils. After entering heat exchange coils from upper inlet, gaseous refrigerant is gradually cooled to be liquid form from top down. The strong wind of fans makes spray water fully cover the heat exchange surface of the coils evenly, and this tremendously increases the heat exchange efficiency. Partial calefactive spray water get vaporized and takes away massive heat with the air flow.
