The water quality, water temperature and cooling tower design dictate which pack to select as well as considerations for removal and maintenance. Construction of Cooling Tower. This type of fill provides much more water surface exposure per cubic foot than splash type fill. Evaporative cooling is the process where warm water from an industrial process is pumped up to the top of the cooling tower where the water distribution system is. It is important to periodically inspect an operating cooling tower for good biological control and to have a proactive water treatment plan in place, per ANSI/ASHRAE Standard 188 and Guideline 12. The tower structure (frame) encloses the cooling components (e.g. The packing ensures maximum contact between air and water to enable cooling. By no means does this type of packing replace the need for water treatment but rather provides additional protection in areas that are not reached by the water treatment. Of course, it is possible to increase the performance of the cooling tower by specifying a smaller flute size and to the in turn, decrease performance by using a larger flute size. Tower Design – The type of packing used must be suitable for the type of tower. Light weight, cross flow, modular packing will not only maintain the system performance but improve the maintenance regime through being easy to remove, clean and replace as required. Although theoretically easy to separate and clean. Types: Induced draft counter flow type with film flow packing as heat exchange fill media. Understanding the duty of the cooling tower is important when considering the packing. Generally measured upwind of a tower in a number of locations sufficient to account for all extraneous sources of heat. Countercurrent-induced draft towers are the most prevalent in the process industries, capable of cooling water within just over 1 °C (2 °F) of the wet-bulb air temperature. In vertical fills, as the name suggests, the flutes are arranged vertically. Please try again in a few minutes. A basin is provided at the bottom of the cooling tower to collect the cold water which is to be reutilized. Our company choose the high quality Fill Packing Media for the cooling tower. There are many different types of tower packing and tower fill materials. The distance between the top of the cooling tower packing and the bottom of the fan should be 1.2 times the diameter of the fan. This is a permanent GRP open mesh grid that is installed beneath the bottom layer of the packing. Cooling Tower Hygiene An unclean tower can be an amplifier of unhealthy biological agents. Tower Design – The type of packing used must be suitable for the type of tower. Using the incorrect packing can seriously hamper system performance and cause overflow issues if water is directed through the pack in the wrong direction. This article focuses on cooling towers and more specifically, open circuit cooling towers and the importance of the heat transfer layer of cooling tower packing. Companies affiliated with GlobalSpec can contact me when I express interest in their product or service. A condenser is used in the high pressure side of a refrigeration or air conditioning system to convert the high-pressure vapour refrigerant from the compressor into liquid refrigerant. The counter flow type cooling tower mechanism is displayed below. Tower packing includes structure and gauze packings as well as high-performance trays and custom-designed internals. Cooling tower packing is one of the most important parts of a cooling tower. This separates the cooling circuit from the process loop. Using an anti-legionella packing material provides additional protection in areas of the cooling tower that water treatment doesn’t reach but is not a replacement for an appropriate water treatment regime. Modular blocks of packing can be assembled in a variety of ways. Include me in third-party email campaigns and surveys that are relevant to me. GlobalSpec may share your personal information and website activity with our clients for which you express explicit interest, or with vendors looking to reach people like you. The experimental study was conducted in a forced draft cooling tower. Depending on the design of the tower, air is either pushed through (forced draft) or drawn through, (induced draft) the packing layer. The variations in many variables, which affect the tower efficiency, are described. Cooling Tower Fills are also named cooling tower filler, cooling tower filling, cooling tower fill packing, cooling tower fill media, cooling tower infill,cooling tower honeycomb fills etc. Learn how natural draft cooling towers work! A heavily fouled, narrow fluted pack will be far less efficient than a splash, grid or larger fluted pack that is not fouled. Packing comes in all shapes and sizes and it is important to know when and where to use each type. Most packaged cooling towers use fans to force or draw air through the tower. Modular Packing for Cross Flow Cooling Towers. The co… Today, plastic in the form of either polyurethane (PP) or Polyvinyl Chloride (PVC) is the most commonly used material for packing. Replacement of cooling tower packing , It need to remove waste cooling towers on the basis of the tower clean and clean, scientific laying of new packing in order.The replacement of old and new construction, generally follow the following steps: 1. the construction site before the protection of other equipment, the necessary isolation and listing. Introduction Cooling towers are used for cooling large amounts What is a Cooling Tower A cooling tower extracts heat from water by evaporation. Refer to HSG274 Part 1 for specific cleaning requirements suitable for your system design and process.

Water Temperature – Where the return water temperature is high, typically in excess of 80oC, there are special high temperature packs available. These should always be specified where this is the case as packing not suited to these high temperatures can melt and lose its integrity. Reducing the required size of a cooling tower by typically 2/3rds. Tower packing is also used in water treatment, direct-contact hot water production, oxygenation, degasification, absorption, desorption, rectification, extraction, desalting, drying, mixing, fish farming, biological filtering, and the treatment of greenhouse gases. Structured packings provide higher efficiency and lower pressure-drop than either random packings or trays. Depending on the application, packing may be random or structured. Installing modular packing, that can easily be removed, makes cleaning and future replacement far easier. Passive or natural draft cooling towers combine the upward motion of warmed air with a steep chimney architecture to organically pull air throughout the tower. Pack should be regularly inspected through either removal or by way of a borroscope inspection, to check for scaling and fouling levels. Some products are comparable to pall rings in terms of mechanical strength and efficiency. In the case of an open circuit cooling tower the heat transfer surface is the cooling tower packing. Mechanical … This allows for easier flow of more polluted water. Vistech is an established engineering business focused on cooling technology.

In the case of water cooled condensers, the warm water being pumped by the condenser s… In a crossflow tower, air flows horizontally through the cooling tower’s structure … The medium used in a condenser may be water or air, depending upon the application. ♦ First, the cross-flow cooling tower standard size. It should be noted that the same biocide is available in drift eliminator materials and even GRP cooling tower casings. Contrary to popular belief, swapping out OEM cooling tower packing with a generic pack will not necessarily reduce system performance. For thermal performance levels typically encountered in air In basket held pack, the baskets are often plastic coated wire, which over time degrades, exposing the wire which causes corrosion in the tower. Water is circulated over a coil within the tower, which through input from the fan delivers evaporative cooling to the process loop, which in turn, returns cool water to the application. I agree to receive commercial messages from GlobalSpec including product announcements and event invitations, This is a method of cooling that has been used by humans for thousands of years, as far back as the ancient Egyptians and Persians; who used wind shafts on their roofs to catch the wind and pass it over subterranean water. As such, the hot exhaust gases and/or steam from a gas scrubber, incinerator, furnace, pollution control device, or similar equipment pass through a vertical column; the hot gases rise in the flue. Cooling tower fill will be packed in wooden pallets or wooden case,with plastic film wrapped inside. This in turn extends the life of the pack. This cooled air would then be discharged into buildings, providing the origins of comfort cooling. The packing height in FBCT reduces considerably because of fluidization. The main function of cooling tower is to reject heat of hot water into atmosphere & cooling down the water for further reuse.There are different types of cooling tower Anti-Legionella packing, often blue in colour, is impregnated with a non-leaching biocide that lasts for the lifetime of the packing, and provides additional protection against bacteria.

Various types cooling tower fills and accessories, applicable to various models cooling towers. Cooling tower is simply a one type of heat exchange equipment where air & water comes in to the direct contact with each other. Water in the tower packing, water from top to bottom, air from the bottom, both flow to the opposite of a cooling tower. Not only does this allow operatives to work safely at heights, in accordance with the Working at Heights Directive, but also provides improved support for the pack through distributing its weight evenly across the tower. Therefore, we must choose high-quality cooling tower packing. The heat and resistance characteristics of the cooling tower packing are the main factors affecting the cooling efficiency. MX Fill is available in MX75 configuration and higher-performing MX625 configuration. as well as subscriptions and other promotional notifications. Note that despite the different designs, the basic function remains as that of dissipating heat from a building system or a process to the air through evaporation. Stephen Hall, in Branan's Rules of Thumb for Chemical Engineers (Fifth Edition), 2012. In cross fluted packing, the flutes are arranged diagonally opposite each other to further increase the total surface area. The openings within cooling tower packs are commonly referred to as flutes. size Fluidized Bed Cooling Tower (FBCT) is found to be encouraging. An important device used in any refrigeration or air conditioning system is a condenser. This has the potential to occur in all towers irrespective of the quality of the water distribution. There are many different types of tower packing and tower fill materials. Historically, cooling tower packing was constructed using wood, either in a grid / splash pack formation or layers of off-set lathes. Other types of tower packing are also available. Why would I need this if I have a robust water treatment regime?Although cooling tower water must be treated to minimise the risk of harmful bacteria including legionella, there are always areas of the packing that are in a wet / dry state. This should also be the case when looking to improve the performance of the cooling tower. There are also larger cross fluted options if required. As long as the replacement packing delivers the same level of heat transfer and is suitable for the design of tower then it is perfectly acceptable, and in some instances advantageous to replace OEM packing with a generic variant. In Comparison, a closed circuit cooling tower has a primary and secondary circuit. When the packing is removed, it also provides an excellent opportunity to install a permanent safe clean platform.

These types of cooling towers are factory preassembled, and can be simply transported on trucks, as they are compact machines. The cooled water flows through the process and returns to the cooling tower, heated by the process, ready to be cooled again through evaporative cooling. Cooling Tower FILM-TYPE FlLL PACKING FILM-FILL REGION SPLASH-TYPE FlLL PACKING dd db db db Fig. because of its ability to expose greater water surface within a given packed volume. FREE Tower packing materials provide a high surface area with a low bulk density. After many years of development of this technology, cooling towers are available in different types and sizes. The smaller the flute size, the larger the surface area per m2 therefore the larger the film of water, creating  a higher potential heat rejection per m2. Sheet packing is installed using hangars. It is also lightweight, making it easier to handle and therefore encourages replacement and regular removal for cleaning. For cooling towers, mechanical equipment that cools water produced by industrial processes like chemical processing and food processing, this is especially true. Keywords: cooling tower, ceramic packing, efficiency I. For example, cross flow cooling towers require cross flow packing and likewise, couterflow cooling towers require packing designed for either forced draft or induced draft cooling towers. There are many different types of cooling towers but the cooling tower working principles stay pretty much the same.Most cooling towers work based on the principle of “evaporative cooling“. 1. We provide consultancy, technical design, manufacturing, installation and maintenance services for industrial and commercial cooling systems. Ceramic structured packing is designed to promote the mixing and radial distribution of the liquid and gas streams. Each of these is applicable in a certain load configuration, the reason it is important to outline the options available. Ensuring the performance of the cooling tower packing is critical to the overall performance of the cooling tower. ACCESS Cooling tower packing will ultimately require replacement. Approximately half of the fill used in crossflow cooling towers, and virtually all that which it utilized in counterflow cooling towers is film-type. Cooling tower packing is the main factor that promotes hydrothermal cycle. Features include high distillation, absorption, and stripping efficiency; high strength to weight ratio; and a high specific heat transfer coefficient. It should be noted that it is possible to have an open circuit tower (with heat transfer pack) but create a closed circuit through the introduction of a heat exchanger, which achieves separation of the process side and cooling side of the system. Today, evaporative cooling adopts exactly the same principles but uses technological advancements in materials and design to further improve this efficient method of cooling. Plus and minuses of each cooling tower material is given below: These come in various sizes, typically ranging from 12mm to 38mm. This is of particular importance when it comes to replacing the packing, which will be inevitable over the typical life of any cooling tower. MX is a hanging film type cooling tower fill which spreads the water into a thin film, flowing over large vertical surfaces, promoting maximum exposure to air flow.
