Description(What is Closed Circuit Cooling Tower?)

SCT-45 is advanced version of SCT-30, it’s medium-size Stainless Steel Closed Circuit Cooling Tower among SCT series, applicable to one-to-one industrial equipment for cooling, such as forging and casting equipment. It also used in small and medium scale plastic molding factory, making your equipment clean without limescale. SCT series is also easy maintenance just like SCT-30, so that the machine can be regularly cleaned and maintained without supplies, modular accessories can be fast to deal with maintenance problems, this is a closed circuit cooling tower not only convenient, but also beautiful and environmentally friendly.

SCT cooling tower maintenanceSCT-45 is an eco-friendly and sustainable closed circuit cooling tower with SUS304 shell and detachable design for simple maintenance to reduce labor and technical cost.

Heat exchange coil

cooling tower copper tubeHeat exchange coil made of Japan Mitsubishi copper tube has high thermal conductivity and great ductility. It’s suitable for small closed type cooling system to maximize heat exchange efficiency.

Fill & Water Distribution System

cooling tower fill

Sprinkler system with patented flap was attached on SCT-45. Moreover, ABS heat dissipation fill features high toughness, impact resistance, beat bearing and reusable.

Electronic Anti-stain Device

descaling deviceUnder fixed concentration, SCT-45 with electronic anti-scale device lowers the potential of building up limescale on coil by separating ions.


cooling tower baseBase support that utilizes 2.6mm SUS #304 corner bracket is durable and firm to ensure working stability.

Water Basin

cooling tower water basinWater basin made by ABS one-piece fabricated mold distributes weight of cooling tower evenly. Furthermore, bevel face design of tower’s bottom helps to get rid of dirty easily.

Pump & SUS #304 Cover

cooling tower pumpsExternal circulator motor for SCT-45 takes advantage of high-flow circulator pump and SUS304 waterproof cover to reduce the potential of producing rust for staying outdoors.


Step1: Water Distribution Tube

Water Distribution TubeFirst, open the device case and turn down the sprinkler pipe 90∘counterclockwise for maintenance. After cleaning, put all the parts back and make sure the spray hole upward.

Step2: Fill

cooling tower fill maintenanceFill under the sprinkler tube are piece by piece design. Take it out by screw driver and beat it to get rid of the dirt and scale deposits. Then put the fill back.

Step3: Heat Exchange Coil

cooling tower coil maintenanceOpen the intake louver underneath then use high pressure washer to rinse out the dirt and deposition attached on the coil. PS: When limescale problem occurs, please contact us for professional support.

Step4: Water Basin

water basin maintenanceAfter finishing all cleaning steps above, there will be plenty of deposition, impurities and calcium carbonate in the water basin. Furthermore, to avoid contaminating the circulating system, make sure that water basin is clean before machine operates. PS: Regularly discharging external water of basin is helpful for reducing the increase of calcium ion concentration besides lowering 70% chance of forming limescale.
