Counter-flow Closed Circuit Cooling Towers / Evaporative Closed-circuit Coolers
Comparing to the open-system cooling towers, easier to maintain is a distinct feature of ICE’s evaporative closed circuit coolers which are an excellent option for any cooling system with other benefits following:
► Reduce water consumption, save energy and equipment maintenance.
► Avoid the significant risk of fouling factors in heat exchangers or similar facilities.
► Significant installation and operational costs savings (no need of pump, valves, additional pipe works and etc.)
► Wider application environment – closed-loop equipment is available to operate in sub-freezing outdoor temperatures. It is highly versatile from cooling industrial process equipment to maintaining temperatures in data centers and computer rooms to chemical manufacturing.

Ventilation System (Fan)
Outdoor axial fan with good performance of three-protection design, equipped with aluminum blade and IP56, F class driven motor with induced ventilator which will block the air and reduce the leakage.
Advanced Water Distribution System
ICE evaporative closed loop cooling towers installed basket type spray nozzles remains clog free while providing even and constant water distribution to maximize the heat transfer between air, water and the process fluid to increase the heat rejection efficiency.
The spray nozzles mounted in corrosion-free water distribution pipes for an easy disassembly.
Red Copper Tube
The key component tub is applying with high quality T2 type red copper which purchased from famous brand manufacturer to ensure a reliable and stable performance of our equipments.
Drift Eliminator
Constructed and made of PVC to reduce water loss during wet operation and limits the drift rate to lower water consumption and avoid scale.
Louver with Damper
There is a damper serves to control the air flow during the operation of cooling towers been applied in certain water, air heat pump system or similar cooling process to avoid the heat loss during the downtime of equipment especially in cold weather.
Electric Heater
When the atmosphere temperature is above 0℉(-18℃), with the electric heater the basin water temperature will not lower than 40℉(4.4℃). There is a low water protection set in the heater to ensure it will only work when it was immersed in water. All the elements regarding electric heater been installed inside the case and adapt for the outdoor operation.
Slope-design Water Basin
The slope design (tilt towards pollutant discharge exit) to avoid water stagnation and the stainless steel strainer will improve the overflow and pollution discharge simultaneously clears the pollutants and impurities in the basin.
Casing Material
ICE standard cooling towers use the latest highly corrosion-resistant coated steel sheet which consist zinc as the main substrate, in combination with Al, Mg and a trace amount of silicon. The service life is 3~6 times longer comparing with normal aluminized zinc steel sheet and the heat-resisting and thermal resistance feature is also excellent.




The cooled dry air enters through the louvers on each sides of the tower in the bottom, and drawn upwards and over the coils by the force from the axial fan which installed on the top, agitating the falling water (came from the water distribution system) and increasing the transfer efficiency of heat in a state of hot wet air discharged out of the tower into the atmosphere. During this working process, a small amount of the re-circulating water evaporates due to latent heat transfer through the tube and walls of the coils, removing heat from the system. In this mode of operation, due to the evaporative performance lower the leaving water temperatures and the fan energy been saved.
DS: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.
Non-direct Drive Axial Fans
DS: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.
LOW NOISE FANS
Fans with low noise design, suitable for installation locations with strict noise limit, 6 to 12 db(a) lower than standard fan system.
Spary Nozzies
DS :The Spiral Target Nozzles used for cooling 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.
Spar Pump
DS :Cast iron material,Siemens motor High flow and low pump 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.
Fill
DS: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
DS: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.
Spary pipe
DS: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
DS:Heavy duty floating valve, made in stainless steel, floating ball in engineering plastic or stainless steel, with long service life. Water level adjustable.
Fasteners
DS :Fasteners of leading brands, standard materials in steel dacromet treated, stainless steel on options. Intensity of fastners is higher than average.
Control Panel
DS:The control panel is optional for each cooling tower, or a group of towers can share a central control station. The enclosure can be made in powder coated carbon steel, or stainless steel on options, with or without weather proof arrangement.
Circulation Auxiliary Section
DS:Circulation Pumps with Transfer Water Tank, as an integrated solution of circulating system, with PID design on request.
Protective Accessories
DS:For maintenance convenience and safety, made in HDG steel or stainless steel.
Eletrical Heater
DS:Applied to heat the freezing water when restarting the tower during winter season in some area.

ICE series belong to induced draft type cross flow cooling towers. During the working process, dry cool air is inlet through wide louvers on one side of the tower, then directed through the heat exchange coils and wet deck fills across the spray water, becoming wet hot air, eventually induced draught out of the tower into the atmosphere by the fans on the top. In this process, a part of heat from the fluids inside the closed loop is transferred efficiently, and removed continuously.
