Product Description
GKM Series Air Cooling Tower GKM Series have been developed since 2012, with a wide range of cooling capacities, and customized in most cases. The enclosure is made in Mg-Al-Zn alloy coated steel, or stainless steel optional. And the heat exchange coils is made in Copper Tube or stainless steel tubes fitted with aluminum or copper fins around the tubes. The fluid inlet and outlet are set on the same side, more convenient and economical for pipe lines installations. The overall dimensions can be tailor-made to suit standard 20’ or 40’ shipping containers in order to minimise freight costs. GKM Dry Cooling Towers are more suitable to cool inlet fluid of higher temperature, widely applied in circulating fluid (water, oil, gas) cooling for Air Compressors, Heaters, Furnace, and other machines in Gas Stations, Refinery Industries, etc. , especially in the area lack or short of water resources. Product Description Air Compressor Machine 
Note: All the data is under the condition of 28℃ wet temperature. If any change of condition,the data will change.
Closed Water Cooling Tower shell is made in Mg-Al-Zn alloy coated steel, of "SuperDyma" series from company Nippon Steel, originally imported Japan. This special alloy coated steel is much better than galvanized steel in corrosion proof performance. 
STRUCTURE & CASING
The tower enclosure is made in special alloy (Mg-Al-Zn) coated steel panels, originally imported from Nippon Steel or Posco. These panels exhibit superior corrosion resistance, and self-heal when scratched during the service period. The panels are bolted and sealed for water tightness. The casing is complete with maintenance access doors for internal inspection convenience.
DRY COOLING COILS
The dedicated dry cooling coils in GKM Series is used exclusively for the purpose of dry cooling, fitted with particularly shaped aluminum fins around the coils tubes, to maximize surface area of heat transfer. The standard coils tubes is made in stainless steel 304, of tube wall thickness 0.6mm, or red copper of wall thickness 0.8mm. Different thickness can be met on request. Each coil is tested under continuous nitrogen gas pressure of 30 bar for 24 hours, to ensure no leaking point.
AXIAL FAN SECTION
The axial fan(s) are fitted with resin or al-alloy airfoil blades perfectly balanced and coupled to a weather proof 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.
ELECTRICAL CONTROL
Each dry tower is under control of an electrical control unit, or a group of towers can share a central control station. The control box can be made in powder coated carbon steel, or stainless steel on options, with or without weather proof arrangement. In cases digital or remote control function required, the PLC can be applied and programmed according to the project demands.
SURFACE FINISH
The standard Cooling Tower is delivered in alloy coated steel finish without any additional painting, unless other color is ordered as an optional item.

Company Information FAQ 
Below information are normally required to know for selection of a most proper tower model and solution: | Application: | (Explanations: Where the cooling towers will be used for? e.g. for HAVC system, Air Compressors, Melting Furnaces, etc.) | |||
| * Water Flow Rate: | m³/h | (Explanations: How many Tons of water required per hour?) | ||
| * Inlet Water Temp.: | °C | (Explanations: Temperature of hot water to be cooled) | (also descriped as "water temperature drop") | |
| * Outlet Water Temp.: | °C | (Explanations: Temperature of cooled water, usually it shall be at least 3~4 °C higher than the wet-bulb temp.) | ||
| * Ambiant Temp.: | °C | (Explanations: Highest wet ambiant temp. of the location/area or city to install the tower is essential to know to evaluate the size of towers) | ||
| * Power Supply: | (Explanations: 380V/3 Phases is standard, which we could have in stock, but for customized towers, the delivery time could be longer) | |||
