Purchase guide for DamaTajhiz fiberglass cubic cooling tower DTC-CO 400
- DamaTajhiz fiberglass cubic cooling tower model DTC-CO 400 is designed to work with a counterflow air system.
- In this design in order to cool the circulating water, some of the water in the cooling tower is evaporated and because evaporation is endothermic, the remaining water in the tower gets cool (the maximum temperature which the circulating water can reach is the ambient's wet-bulb temperature) and is sucked by water circulating pumps after gathering in cooling tower basin.
- The performance of fiberglass cooling towers is designed in accordance with the ATC-105 code of C.T.I. Additionally, the performance of these towers is approved by E.P.A.
- Generally, calculation and designing of cooling towers are based on the following standard parameters: temperature of inlet water: 95oF, the temperature of outlet cool water: 85oF, and W.B.T: 75oF.
- Outlet water temperature depends on W.B.T and the maximum temperature reduction in outlet water of the cooling tower is about 3ooC more than W.B.T. For example, if W.B.T of Tehran in summer is 22oC, in the best condition temperature of cooled water in the cooling tower is about 25oC.
- DamaTajhiz fiberglass cubic cooling tower model DTC-CO 400 is of draft induced type. In these cooling towers, air circulation in the tower takes place naturally or could be a forced type. Induction is done by an axial fan placed on top of the tower.
- DamaTajhiz fiberglass cubic cooling tower model DTC-CO 400 has 3 years body warranty, 2 years internal parts warranty, and 15 years of technical support.
Casing
- Body parts of DamaTajhiz cooling towers are made of reinforced fiberglass and have high strength. They have two special covers and are UV-resistant. Casing parts can be assembled easily for yearly services.
- All attachments are of non-metallic materials such as PRC-FRP-ABS or stainless steel or aluminum.
- Air inlet vents in DamaTajhiz fiberglass cubic cooling tower model DTC-CO 400 is made such that they have the least resistance against air entering and prevents water loss. These vents can be opened and closed to provide access to the basin of the cooling tower.
Electromotor
- The Electromotor of DamaTajhiz fiberglass cubic cooling tower model DTC-CO 400 is generally of SIEMENS brand and has IP55 sensitivity in a water-resistant thermal class of F.
- Based on their cooling method they are categorized in TE AO and TE FC classes.
- DamaTajhiz cooling towers have standard noise but they are also produced in low noise and super low noise models with different dimensions and prices than other cooling towers.
Packings
- Layers of Sheets in packings of DamaTajhiz fiberglass cubic cooling tower model DTC-CO 400 are waved and are put on each other like a honeycomb.
Steps have a sinusoidal design and their obstruction is impossible so they can maximize heat transfer by providing an appropriate bed for water film formation and fast evaporation and larger interface with air.
- By customer request, drop catcher parts are installed on packings to prevent transpiration of water drops by a fan; installing these parts reduces the water drop jet to less than 0.02 percent of circulating water in the cooling tower (this is less than the amount allowed by EPA).
Water distribution system
- In cubic cooling towers, inlet water enters the tower through a polyethylene central pipe and then is transferred to an aluminum sprinkler head and then is sprayed evenly and radially on packings by distribution arms that have orifices with appropriate diameter and angle.
- to prevent water waste, the least distance is considered between the arm's exit place and packings.
Supports
- Supports of DamaTajhiz fiberglass cubic cooling towers up to model DT-175 are of fiberglass and in higher capacities, hot-dip galvanized supports are used. Cooling towers of model DT50 and higher are subject to O.S.H.R as mandatory standard and hot-dip galvanized ladders are used to access mechanical and electrical parts on the cooling tower.
Inverter system
- In case of customer request, the speed of the fan and motor (RPM) can be changed by installing an inverter system on the electrical panel of cooling towers to provide exact control of outlet water (if an inverter system is ordered a separate electrical board should be provided for the tower).
- The order of inverter frequency change is applied by a sensor in a determined temperature range. The performance of inverters is as frequency changes and therefore electromotor power remains constant.
- When the temperature of outlet water is not so important, the thermostat is used to control water temperature by motor on and off.
Final words
- If the diameter of your fiberglass cooling tower is more than 250cm, it is recommended to transport it to the project site as separated parts to prevent any damage to it. It is obvious that the final assembly of these towers on the project site has separate expenses that should be paid by the customer.
- If it is not possible to transport the integrated cooling tower to the project site or installment site, please order a cooling tower as DEMONTAGE on order time.
- All transport and montage expenses (if needed) should be paid by the customer.
