Square counterflow cooling tower series-Dunham Marley brand all-round introduction
1: GTX-N high efficiency energy saving cooling tower overview
GTX-N open counterflow cooling tower is a mature and reliable cooling equipment formed by our company after years of design, manufacturing, continuous improvement and perfection. The product quality and technical performance are always in the leading position in the industry.
GTX-N open counterflow cooling tower is widely used in industrial heat fluids, metallurgy (blast furnace, continuous casting mold), medium and high frequency induction heater, chemical (heat exchanger), power equipment, casting, forging, quenching liquid, manufacturing, food, air compressor, central air conditioning and many industrial departments as a universal cooling equipment.

2. Basic cooling principle of GTX-N open counterflow cooling tower

GTX-N open counterflow cooling tower is a device that uses the contact (direct or indirect) between air and water to cool and dissipate heat by spraying packing, and takes away the heat through fans to cool water, with water as the circulating cooling medium.

GTX-N open counterflow cooling tower is mainly composed of six parts: spray packing system, spray water circulation system, collector system, control system, shell and frame, and fan.

Under the drive of the main circulation pump, soft water circulates in an open system within the cooling tower's spray packing system. Heat is transferred to the surface of the packing, and the spray water falls vertically from the top of the tower. The water collector system sprinkles over the outer surface of the packing system, forming a uniform water film. After heating, this water forms saturated hot steam. Fresh air enters the tower through the intake at the bottom, and the airflow is perpendicular to the water flow. During the circulation process, the spray water is sprayed onto the surface of the packing system for heat exchange, with the heat being discharged into the atmosphere by the fan. To reduce the temperature of the circulating water, two types of heat exchange occur: the heat transfer between the cold air and the cooling medium, and the heat absorption from the evaporation of the spray water. This process absorbs heat, thereby lowering the temperature of the working fluid, and the saturated hot steam is discharged upward by the fan.

3.GTX-N square counterflow cooling tower design process

Ø Outer shell: using domestic Baosteel, Guogang and Pangang produced: magnesium aluminum zinc coated steel /SS304L molded steel plate.
Ø Maintenance: Century Hualeng has a unique design that allows access to the maintenance channel inside the equipment.
Ø Inlet grille: Century Hualeng's unique high-efficiency inlet grille (PVC material) for separate cooling of spray water and cooler.
Ø Fan: It adopts a three-proof motor with IP55 protection class and F insulation class.
Ø Wind cylinder: Inductive FRP or sheet metal is processed into a molded wind cylinder to reduce air backflow and leakage.
Ø Protective cover: corrugated carbon steel integral hot-dip galvanized protective cover to prevent debris from entering the fan.
Ø Sprinkler head: a new type of flower nozzle, with fine water droplets, uniform water spraying and large water distribution area.
Ø Collector: FRP or sheet metal is processed into a closed flow basin design
Ø Water collection tank: large water collection, wide area, good heat dissipation, fully meet the technical requirements of sprinkler water.
Ø Float ball valve: 304 stainless steel to ensure the water tank storage capacity.
Ø Pre-cooling packing: Century Hualeng type heat dissipation packing is used. Water evaporation heat exchange reduces the temperature of cooling water, and the water blocking plate in front effectively reduces the loss of floating water.
Ø Brand of electric control box: Chint/Schneider.
Ø Remote control: start and stop buttons for water pumps and fans.
Ø System control: the system operates a fault alarm system.
Ø Indicators: power on indicator, operation, shutdown and fault display lights.

	1、Century Hualeng-Dunham Power 2、FHL-N series of square counterflow cooling tower is a mature and reliable cooling equipment formed by our company after years of design, manufacturing and continuous improvement and perfection. The product quality and technical performance are always in the leading position in the industry.
	Century Hualeng-Don Han power The base of the fan is made of reinforced sheet metal produced by Guogang/Baosteel and other manufacturers. The base of the fan can be adjusted slightly in circumference, and there are anti-twist iron bars. The contact surface is finely processed, and the motor base has horizontal and vertical fine adjustment holes to ensure that debugging and maintenance are very convenient. Sandblasting is used for rust removal, and epoxy coal tar is used for anti-corrosion.
	Century Hualeng-Dunham Power The PVC material with high thermal performance and easy to block is adopted, and the filler is American horsepower type. The physical and chemical properties of the sheet meet the requirements of DL/T742-2001 "Technical conditions for plastic parts of cooling tower".
	Century Hualeng-Dunham Power The wing type is adopted, and the high quality axial flow fan for cooling tower is adopted by Shanghai Erhuajie/Dezhou Beno/Hebei Jili Wind Power Equipment, and the transmission shaft is made of 0Cr18Ni9 stainless steel.
	Fully galvanized steel duct
	The internal structure adopts simple and practical century, with large space. The water storage space is large, more convenient for maintenance and maintenance, etc.,
	The spray system uses ABS/PP material for low-pressure nozzles, which feature a large nozzle diameter and are designed to prevent clogging. The water is sprayed evenly without any hollowing, and the mist-like droplets do not affect the uniformity of air distribution. The system has a wide range of hydraulic load tolerance and features a self-drain function. The nozzles are connected to the distribution pipes using a threaded connection, ensuring long-term safe operation.
