Description(What is closed circuit cooling tower?)

PCT Series is economical, innovative closed circuit cooling towers transformed traditional open cooling towers to closed circuit cooling towers with abilities to overcome limescale problem. Furthermore, PCT has been granted with patents for heat exchange coil using PE material to maximize its heat dissipation area. There is no doubt that PCT Series can achieve high efficiency and lower capitalized costs.

Innovative Design


②③④⑤closed circuit spiral circulationg system

closed circuit spiral circulationg systemCollecting pipe and shut tube ②③ are made of ABS. Heat resource water is distributed into 18 layers of spriral entwine tue⑤ to perform cold/hot exchange. 18 layers cooling water flow to the plant to be cooled by collecting pipe③ , so it will be form a closed circuit spiral circulating system. Spiral entwine tube⑤ are made of PE material. It can endure high temperature and is anti-corossive. It will not have corrosive risk whether with alkaline-washing or acid-washing. Bellows tube④ increases the surface area 3 times with a patent design of tight spiral staggered. It is spacious. For tubes located outside, it will have effect of heat dissipation and increase efficiency of heat & cold exchange substantially.

①fills⑨⑩spin water distribution device

fills & spin water distribution deviceHigh performance P.V.C filler① are made with honeycomb style fill① The hard fabric with wrinkle and twill surface treatment will increase the layover time of water flow. It will have enough surface to touch air. It will increase effect of heat exchange. It willl distribute water to water holes and lower area evenly. Closed circuit spiral circulating system will perform the best. It will stop ultraviolet ray demage in the closed circuit spiral circulation system and enhance its usage. High performance auto spiral spiral water dissipation device, water distribution nozzel⑨ are made with plastic steel casting. Water tubes are made of PVC plastic with low water pressure, distribute water evenly, water saving and large exchange efficiency.

Heat Exchanger Coil

Heat Exchanger CoilPCT's coil heat exchanger are made with PE tubes. It is anti-corrosive and anti-freeze with clean channel made for special cooling fluid.


Motor and FanFully enclosed outdoor 10P silent type motor ⑦, running low noise, long-term operation in harsh environments. Specially designed low-noise axial-flow multi-leaf fan ⑧, by the balance correction, running quietness, power-saving low noise, below PCT-30 uses of plastic steel and PCT-40 uses aluminum alloy casting.

⑥Support Base

Support BaseBase is assembled with stainless steel tubes. It is lightweight, high carrying capacity, non-corrosive and durable.

⑪⑫FRP Body & Water Basin

Body & Water BasinBody⑪ and store water basin⑫ are made with FRP. It is flexible and stretchable.

Pump & F.R.P Cover

Pump & amp; F.R.P CoverPCT with external circulator motor utilizes large flow rate circulator pump. In humid area, purchasing F.R.P waterproof cover is also a way to extend life span and reduce the potential for corrosion.
