Description ( What is closed type cooling tower? )

HCT Series is the largest line of closed circuit cooling tower. This newest design of double air intake system not only doubles the heat dissipation area but also maximizes the coverage of coil in water distribution system for lowering the possibility of building up limescale.

HCT with alumi-zinc shell achieves the longest life-span and anti-corrosion. Customers can also choose SUS #304 as shell material. Furthermore, the greatest strength of HCT Series is, its heat exchanger coil with SUS #304 material is able to extend life-span and be suited to use in specific environment.

Detail HCT

①Cooling fan stack & Motor

Cooling fan stack & MotorHCT's fan motor that adopts aluminum alloy axial fan with direct-joint structure avoids drawbacks from belt transmission. This fan motor possesses lots of advantages such as long-term stability of product, low noise, no transmission loss, high efficiency, low friction between components and low breakdown rate.

③External circulating water spray system

External circulating water spray systemHCT Closed Circuit Cooling Tower uses big flow rate nozzle for outer circulating distribution system. This reduces clogging issues. The nozzle is placed at the top of the device for easy maintenance. Nevertheless, water and wind are designed to operate the same direction with even water distribution to largely decrease dirt attaching coil.

④Heat exchanger

Heat exchangerHCT's heat exchange coil made of stainless steel #304 with thickness of 1mm is non-corrosive in most specific regions and extended lifetime. The bevel slope design keeps water out while not in use.

⑦Shell material

Shell materialHCT's shell material is made of 2mm aluminium-zinc steel plate. This material includes aluminum with anti-corrosion, zinc with anodic treatment and silicon that combines the strength of aluminium-plated steel and zinc-plated steel. The lifetime of the plate is able to reach is 4 to 6 times longer than galvanized plate.

②Water eliminator、⑤Fill and ⑥Maintenance space

Water eliminator、Fill and、Maintenance spaceHCT Closed Circuit Cooling Tower is designed with the air and water current flows in the same direction for cooling. ⑤ Fill and heat exchanger coil are separated to ensure that the fill do not block the flow channel. Besides, ② Water eliminators are dischargeable to be convenient to clean regularly and maintain efficiency. Also, ⑥ the internal space are large enough to accommodate maintenance person to execute work.
