Fiberglass Cooling Tower(DBNL3-70)

Fiberglass Cooling Tower(DBNL3-70)
All of the cooling tower products introduced in this web site are energy saving, because of lower installation capacity of motor compared among the same kinds at home and abroad. Temperature drop of water in the low noise and extra-low noise type cooling water ranges normally within 3-8C, which is suitable for cooling of air conditioner and other kinds of equipment.The extra-low noise type cooling water takes a series of noise control measures on the basis of the low-noise cooling tower. Its noise value at the standard points is ~5dB(A) lower than that of the corresponding low noise, and therefore, it is more suitable for places with higher requirements for noise level such as hotel, hospital, public building structures and places adjacent to residential area.Industrial type, i. E. Medium/high temperature cooling tower, shows a normal water temperature drop of 10~25C. This type takes a series additional measures to improve diameter of tower body, flow rate, air pressure, power and height of packing, etc. It is appropriate for cooling of service water that has higher requirements for water temperature drop.Its code is as follows:DBNL 3 100 type: D-low noise; B-FRP; N-counter-flow; L-cooling tower; 3-the 3rd modification design.100-Nominal flow rate at typical working conditions is 100m 3 /h.GBNL 3 100 type: G-industrial type, medium and high temperature drop.CDBNL 3 100 type: CD-extra low noise type.DBNL 3 J-100 type: J-water collection type (water pan of this type of cooling tower is 300~400mm higher than that of the ordinary water pan).DBNL3W-100 type: W-no water collection pan type (i. E. No lower body of the tower, which fits for being installed at the upper part of the water tank, and can economize equipment investment and improve temperature reduction effect).Selection and operation:Known values for selection will cover the water amount Q, water inlet temperature t1, water outlet temperature, and design wet bulb temperature, Then, type should be finalized according to thermal performance curve.Concerning cold resistance of the material, it is applicable for area reaching up to 50C, however, for places with the mean atmospheric temperature of the coldest month below 10C, anti-freezing measures should be required upon ordering. The manufacturer can provide rainwater guide to prevent the water from flowing onto the louver.The cloudiness of circulation water should not exceed 50mg/L, and be within 100mg/L for a short term. It should not contain greasy dirt or mechanical foreign maters. Measures should be taken for sterilization and maintenance of water quality.Foundation drawing is for installation reference only. Direction of water inlet/outlet pipe of big tower is show on the drawing, while that of the small tower can be laid freely at horizontal position, however, it should not interfere with the foundation. If there is foundation in the middle part, its load should weight 25% of the operation load, while the other 75% will be shared averagely on the peripheral rectangular foundation. If it is installed on the roof deck, then, additional pressure caused by wind load should be taken into consideration.
