Closed Circuit Cooling Tower Closed circuit cooling tower (also known as an evaporative air cooler or closed cooling tower) is the tubular heat exchanger placed in the tower, through the circulation of air, spray water and circulating water heat exchange to ensure the cooling effect. AUVC not only provides different shapes of cooling towers used in industries, such as round shape cooling towers and square cooling towers, but also offers closed cooling towers and open circuit cooling towers as well. The type of closed circuit cooling tower is widely used in iron and steel metallurgy, power electronics, machining, air conditioning system and other industries. How do closed circuit cooling towers work? Closed-circuit cooling towers make it possible to separate the evaporative circuit from the process circuit (customer circuit). A stainless-steel plate heat exchanger attached to the cooling tower, in its dedicated room, allows a glycol-free operation, and a simplified and unequalled ease of maintenance. The closed circuit cooling tower works as follows On the process side to be cooled (customer loop), the water to be cooled enters a plate heat exchanger connected to the tower and is cooled and discharged. The primary loop is closed and never comes into contact with air. On the secondary side of the cooling tower, the water is sucked out of the pool by a pump and circulated through a stainless steel plate heat exchanger. The water leaving the exchanger is piped to the top of the unit. This water is graded and evenly dispersed over the exchange surfaces by dispersers (also known as water distribution nozzles). Air driven by fans (axial or centrifugal) enters from the lower part of the cooling tower, is heated and saturated with water and exits from the upper part, passing between the exchange surfaces.

Cooling Tower Motors Cooling tower motor is a new type of energy-saving and environmental protection improved motor, with protection grade of IP55, insulation grade of B, and power supply voltage of 380V and 50Hz. Generally, a closed waterproof motor is used in the cooling tower, which can operate for a long time in outdoor humid and high temperature environments. The cooling tower motor material is cast iron and aluminum shell. Derived from one of the most rugged motor platforms used in the most demanding industrial applications, direct drive motors are the right solution for operation in hot and humid environments in towers. Direct drives are ideally suited for cooling towers, air-cooled condensers and air-cooled heat exchangers.
Cross Flow Cooling Tower Cross flow cooling tower is an induced draft cooling tower that can cool water. Cross Flow Cooling Towers are a type of heat exchange system used in various industrial processes and HVAC (heating, ventilation, and air conditioning) systems to remove excess heat from the surroundings. These towers work on the principle of evaporative cooling, utilizing water and air to transfer heat from a process or a system.Cross flow cooling tower working: The water flows vertically from the top of the tower, and the air flows horizontally through the filler. The air flow is orthogonal to the water flow in the cooling tower. Advantage Compact Design: Cross Flow Cooling Towers have a more compact design compared to other types of cooling towers, making them suitable for installations with limited space or height constraints. Their vertical structure allows for efficient use of space. Energy Efficiency: These cooling towers typically consume less power due to their design and operation. The water distribution system and air movement mechanisms result in lower energy requirements, leading to reduced operational costs. Effective Water Distribution: The fill material inside Cross Flow Cooling Towers ensures even water distribution, maximizing the surface area available for heat exchange between water and air. This helps in achieving better cooling efficiency. Lower Noise Levels: Cross Flow Cooling Towers tend to produce less noise during operation compared to other types, which is advantageous when the cooling towers are located near residential areas or noise-sensitive environments. Easy Maintenance: The design simplicity of Cross Flow Cooling Towers makes them easier to maintain and clean. Access to internal components and fill material is typically more straightforward, simplifying maintenance tasks. Handling Varying Flow Rates: These cooling towers can handle varying water flow rates effectively, making them versatile and adaptable to changing process requirements or external conditions. Good Water Quality: The water exposed to air in the cooling process is less likely to get contaminated with debris, dust, or other impurities. This can help maintain better water quality and reduce the need for frequent water treatment. Improved Water Conservation: Cross Flow Cooling Towers can be designed with features like drift eliminators, which help minimize water loss due to evaporation. This contributes to water conservation efforts and reduces the overall water consumption of the cooling system. Suitable for Warm Climates: Cross Flow Cooling Towers are well-suited for warm climates because of their effective cooling capacity even when the surrounding air temperatures are relatively high.
What is the Difference Between a Wet Cooling Tower and a Dry Cooling Tower? 1. The volume and price distinction of wet cooling tower and dry cooling tower Generally speaking, wet cooling towers are small in size, high in efficiency, and inexpensive. In contrast, dry cooling towers are bulky, low in efficiency, and expensive. 2. The heat exchange method of wet cooling tower and dry cooling tower is distinguished (1) The heat is taken out by the cooling liquid and dissipated in the air through conduction and evaporation, which is called a wet cooling tower. The cooling gas or air takes heat out and transfers it into the air through conduction, which is called a dry cooling tower. The cooling tower that completes the wet cooling method is a wet cooling tower, and the cooling tower that implements the dry cooling method is a dry cooling tower. While the wet and dry cooling tower is actually a combination of a closed cooling tower, cooler and wet cooling tower. (2) One of the heat exchange methods between water and air in the cooling tower is that the air flowing through the surface of the water is in direct contact with the water, and the heat in the water is transferred to the air through contact heat transfer and evaporation. It is called a wet cooling tower. (3) The heat exchange efficiency of the wet cooling tower is high, and the limit temperature at which the water is cooled is the wet bulb temperature of the air. However, water is lost due to evaporation; evaporation also increases with the salinity of the circulating cooling water. In order to stabilize the water quality, part of the water with higher salinity must be drained; wind blowing can also cause water loss. These water losses must be continuously replenished with enough new water. Therefore, the wet tower must have a source of make-up water. (4) In water-deficient areas, when it is difficult to replenish water, only dry cooling towers can be used. The heat exchange between air and water in the dry tower is to transfer heat through the surface of the radiator composed of metal pipes, and transfer the heat of the water or steam in the pipe to the air flowing outside the radiator. The heat exchange efficiency of the dry tower is lower than that of the wet tower, and the limit temperature of cooling is the dry bulb temperature of the air.
Cooling Tower Pump Cooling tower water circulation pumps are critical to the chiller system they serve. Your chilled water system may even have more than one type of chilled water pump, with one main pump circulating water through the chiller and another main pump circulating water through the building. All chilled water or condensate pumps should have good seals, bearings, rotating parts and drive motors. Both circuits have controls, bypasses and valves that are often overlooked during inspection and maintenance. Pump filters should also be clean. Characteristics Of Cooling Tower Pump a.Stable operation: the absolute concentricity of the pump shaft and the excellent dynamic and static balance of the impeller ensure smooth operation without vibration. b.No leakage: cemented carbide seals of different materials ensure no leakage of different media. c.Low noise: the water pump supported by low noise bearing runs smoothly, and there is basically no noise except the weak sound of motor. d.Low failure rate: the structure is simple and reasonable, the key parts are equipped with international first-class quality, and the trouble free working time of the whole machine is greatly improved. e.Easy maintenance: easy to replace seals and bearings. f. Less land occupation: the outlet can be left, right and up, which is convenient for pipeline layout and installation and saves space.
