Purchase guide for DamaTajhiz circular fiberglass cooling tower DT.C.1000

In addition to producing circular open-circuit fiberglass cooling towers, DamaTajhiz Engineering Company can also produce closed-circuit cooling towers in compliance with all technical principles and conventional standards for industrial use. The design of circular fiberglass cooling towers is circular.

Performance of DamaTajhiz circular fiberglass cooling tower DT.C.1000

  • In this case, some of the water in the circular fiberglass cooling tower of the 80-ton refrigeration equipment is evaporated to cool the circulating water. Due to the heat absorption of the evaporation process, the rest of the water inside the tower pan is cooled (with a temperature higher than the WET BULB temperature of the environment ), which after collecting in the pan of the cooling tower, is sucked by the water circulation pumps of the tower and enters the condenser of the water chiller.
  • Fiberglass cooling tower performance is designed according to the American Cooling Tower Institute (C.T.I..) code ATC-105. In addition, the performance of this type of tower has been confirmed by the American Environmental Protection Agency (E.P.A....).
  • In general, the calculation and design of all types of cooling towers have been done based on the inlet water temperature of 95 degrees Fahrenheit, the outlet cold water temperature of 85 degrees Fahrenheit, and the ambient humid air temperature of W.B.T.75.
  • The temperature of the water leaving the cooling towers depends on the temperature of the humid air in each place, but the expected decrease in the temperature of the water leaving the cooling tower is about 2.5 to 3 degrees Celsius higher than the temperature of the humid air (wb) in the same place. For example, suppose the maximum humid air temperature in Tehran in summer is equal to 22 degrees Celsius in a normal state. In that case, the temperature of cooled water in the cooling tower of the temperature equipment will be around 25 degrees Celsius. Of course, we can reduce this temperature difference to some extent by increasing the volume of the packings, fan speed, and airflow in the cooling tower, but this action will increase the noise and splashing of the water in the tower.
  • The fiberglass cooling tower is of the suction type (DRAFT INDUCED), and the airflow in the tower is possible in both natural and forced ways; the forced suction is done by the AXIAL fan located on the top of the tower.

Cooling tower body and pan (CASING)

  • The body parts of the temperature equipment cooling tower are all reinforced and high-strength fiberglass resistant to U.V... rays with two layers of external coating. The body parts and pan are easily assembled for annual services—non-metallic materials such as PRC-FRP-ABS, stainless steel, or aluminum.
  • The air intake valves of the fiberglass cooling tower manufactured by the DamaTajhiz company are made in such a way that they have the least resistance to air entry and prevent water drops from being thrown out. These valves can be opened and closed to access the cooling tower pan.
  • Fibers: The type of essential fibers in producing fiberglass parts is the type of wicker or mesh made in Korea, and needle, arzil or matte fibers are used to strengthen the body.
  • Resin: The basic resin in producing fiberglass parts is unsaturated polyester resin, isophthalic model, B.K.C.... brand, with ISO9001 quality management certificate from S.G.S.... company, and the desired resin code is 2200.
  • The basin of the cooling tower is made of one fabric made of P.R.F. fiberglass with a thickness of 10 mm and two layers of matte reinforcement fibers, more than the panels, to increase the strength, as well as two layers of vinyl anti-UV gel coat. Ester is made in the inner wall, which is also drawn from the outside for easy installation on the foundation of the chassis.
  • Louvers or shutters, air intake made of P.R.F.. blade or sinus model with 8 mm thickness - includes 12 valves on 4 sides of the cooling tower, considering the linear speed of the incoming air in the louvers equal to 5 meters per second in the design they take.
  • The fan stack or fan oven is made of P.R.F.. fiberglass fibers with a thickness of 8 mm and includes anti-UV materials resistant to ultraviolet radiation. The diameter of the top opening of the fan stack is 235 cm.

electric motor

  • The electric motors of DamaTajhiz cubic fiberglass cooling towers are generally Motogen products and have IP54 sensitivity.
  • DamaTajhiz cubic cooling towers are standard in noise level, but they are also produced in low-noise and ultra-low-noise types, different from other towers in size and price.
  • The fan of the system is suction type, axial or axial. It has aluminum material, an aerodynamic section, 6 blades, low noise Super model, with a width of each blade of 25 cm, and the fan angle is set at 16 degrees.
  • The material of the airfoil propeller is 6-blade adjustable, anti-corrosion, and has static and dynamic balance, which causes smooth movement and long life of the bearings.
  • The power transmission system to the money belt is also 1 to 4.

electric motor (MOTOR)

Cooling tower packings

  • The packing sheets of the thermo-equipped fiberglass cooling towers are corrugated and stacked on top of each other in the form of a honeycomb, and the steps of the grooves of the packings are designed sinusoidally. There is no possibility of water sediment clogging them to create a suitable substrate for forming a water film and rapid evaporation and the contact surface—more with air to maximize the heat transfer. Packing of thermal equipment cooling towers is usually 19-step film type and made of P.V.C.. material with a special antibacterial coating with pharmaceutical grade (with F.D.A.... approval), and 400-micron thickness or splash packing or random splash etc. made of first grade P.P.. material with pharmaceutical grade and It is antibacterial with a thickness of 500 microns, the height of the packing media arrangement with a unique surface is 170 square meters per cubic meter, which is offered according to the choice and order of the respected buyer.
  • At the request of the respected customers, drip catch parts are also installed on the packings to prevent water droplets from coming out by the fan to reduce the water particle ejection to less than 0.02 of the circulating water in the cooling tower (which is the minimum allowed amount). By the U.S..... Environmental Protection Agency is less.

Cooling tower packings

cooling tower water distribution system

In circular cooling towers, the incoming water enters the tower through a central pipe made of polyethylene. Then it is transferred to the sprinkler head (SPRINKLER HEAD), made of aluminum, and then through the distribution arms, which have openings with a suitable diameter and angle. They are sprayed evenly and radially on the packings by the pressure created by the tower pumps. The minimum distance between the arms outlet and the packings has been considered to prevent water wastage.

Supporters

  • The supporting bases of the temperature equipment cooling tower up to the DT-175 model are fiberglass and used in higher capacities than hot galvanized supports.
  • Cubic cooling towers in D.T... 50 and higher models are subject to the O.S.H.R.. mandatory standard. Hot-dip galvanized ladders are installed to access the mechanical and electrical components of the cubic cooling tower.
  • The supporting chassis of the fan stack is made of galvanized sheet with a thickness of 6 mm, and the protective nets of the fan guard are made of heated iron with plated zinc ranging from 83 to 110 microns. The bases and chassis of the motor holder are also made of hot-dip galvanized angle.
  • The panel holder, cooling tower floor chassis, external supports, and coil holding support on the tower chassis are made of hot galvanized zinc-type iron with a thickness of 150 microns.
  • All the internal support supports, including the supports of the drippers and the packing, are made of fiberglass with the pultruded process of anti-corrosion P.R.F. tensile fibers and an anP.R.F.h tensile and bending strength 4 times that of iron in one direction.

Eliminator or dropper

P.P. eliminators are installed in the upper part of the nozzle, which is a blade type and reduces the number of water drops to less than 002.0% of the water in the rotation to reduce the number of water droplets drifting from the top of the cooling tower.

Components of the cooling tower fan

  • Fan blade: The fan blade is made of plastic reinforced with glass fibers (fiberglass), which has more chemical and physical stability than aluminum propellers, and due to its polished surface, it has less friction with the surface and minimizes air resistance. Isophthalic resin and high-quality fibers are used in the production of these propellers.
  • Fan handle: This part is the connecting factor of the propeller and the hub, which is made of carbon steel with galvanized plating.
  • Fan hub: It is made of unbreakable cast iron and is in the form of a coupling, which makes it possible to assemble the propeller quickly.
  • Types of bolts and nuts: In producing propellers, dry bolts and nuts are used, which have a lot of resistance. Stainless steel connections are also used if the fan is placed in acidic and corrosive environments.

Inverter or variable speed cooling tower system

In the case of ordering and purchasing a cooling tower customer, by installing an inverter system in the electrical panel of the cooling tower, the speed of the fan and motor is changed to control the temperature of the cooling tower outlet water accurately (in case of ordering an inverter system, the tower must be equipped with a panel Installs separate electricity.)
The command to change the frequency of the inverter is operated by a sensor set in a temperature range. The operation of inverters is in the form of frequency changes. As a result, the power of the electric motor remains constant. In cases where the output water temperature is not very sensitive, the thermostat controls the output water temperature by turning the engine off and on.

Estimating the required space for installing a cooling tower

  • All cooling towers must be installed outdoors and exposed to the direct flow of free air.
  • There should always be enough space without obstacles around the cooling tower so that fresh and sufficient air is readily available to the tower. (According to ASHRAE standards)
  • The hot air coming out of the tower must be discharged in such a way that it is not possible to return and recirculate it to the cooling tower because the recirculation of such air in the tower causes the wet bulb temperature to increase and the water at the tower outlet to remain warm. becomes
  • In general, we can say that to install towers up to 2.5 meters high for each ton of refrigeration, we need a surface of 0.1 square meters (in construction uses) for every 50 square meters under the building's helpful structure.
  • Also, in towers with a height of more than 2.5 meters per ton of refrigeration, we need a surface of 0.12 square meters per 50 square meters under the building's helpful foundation.

Transportation and installation of the cooling tower

Suppose the diameter of the fiberglass cooling tower you purchased is more than 200 cm. In that case, it is recommended to transport it separately to the project site to prevent damage to the cooling tower during transportation. The final assembly of the cooling towers with a diameter of more than 200 cm will be done at the project site by paying a separate fee.
If it is impossible to transport the cooling tower to the project site or the installation site on the roof, please order it separately (DEMONTAGE) when purchasing the cooling towers.
All shipping costs and, if necessary, reassembly of the cooling tower at the installation site are the responsibility of the respected buyer.
