Top Cost Performance GHM Series Cross Fow Closed Cooling Tower

SANJIU GHM Series
Top Cost Performance GHM Series Cross Fow Closed Cooling Tower

GHM Series are of capacities from 30 to 366 nominal tons, can work in series as a group for larger capacities. Casing made in special alloy coated steel or stainless steel, Heat exchange coils made in stainless steel or red copper, Wet deck fills made in PVC. All raw materials are of high industrial grade, with superior corrosion resistant features. GHM towers are designed of high efficiency but lower initial and long term costs, easy and economical installation and maintenance. The towers dimensions can be customized to suit standard containers or part icular project conditions. GHM towers are widely applied in different fields, to cool circulating water, oil or other process fluid for HVAC System, Compressors, Furnaces, Data Centers, Ground Source Heat Pumps, Power Generators, Transformers, Converters, Refrigerators, Food and Chemical Production Lines, etc.

Raw MaterialsMain ConfigurationSTRUCTURE & CASING
TStandard enclosure is made of a special type of highly corrosion-resistant steel sheet coated with a 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 inspection convenience.
EVAPORATIVE COOLING COILS
GHM series adopt high efficient heat exchange coils. Optimized coils has effectively reduced air-side resistance, suitable to work with larger amount of spray water, and significantly improved heat transfer efficiency. The heat exchanger combines one or more coils supported by steel structure, firm and durable. This whole section is of patented design, easy to eliminate cooling medium fluid. Standard coils tube made in stainless steel 304/316, or red copper and titanium ally on option. Different wall thickness can be met on request. Each coil is tested under continuous nitrogen gas pressure of 30 bars for 24 hours.
DIRECT-DRIVE AXIAL FANS
GHM series adopt direct-drive axial fans of local leading brands, fitted with resin or al-alloy airfoil blades perfectly balanced and coupled to a weather proof TEFC three-phase 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 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 run at minimized vibration and low noise. Mechanic seals avoid 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.
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 Formosa Plastics, with long service life in tough environment.
Application Fields
A cooling tower is a heat exchange system that removes waste heat from a process system fluid, usually water. Cooling towers are used in both commercial and industrial applications.SANJIU-CertificationPackaging & Shipping
