induced draft counterflow cooling towers
shanghai tyacht induced draft counterflow cooling tower (for short tat series), cooling tower body adopts the high quality hot-dip galvanizing technology, achieve single cooling tower deal with large amount of water, efficient cooling, energy saving and environmental protection. aiming at the inlet and outlet water temperature difference and adverse weather conditions, have a significant role, in the solar photovoltaic industry, iron and steel casting industry and electric power and chemical industry wide acclaim, tat series fully galvanized steel cooling tower adopts unique independent pvc water filler design, the internal structure of reasonable design, beautiful appearance, high heat exchange efficiency, sufficient cooling, acquire high opinion from the majority of customers. according to the different needs of customers, to change the color of the tower body.
advantage:
1) water basin internal inspection and maintenance simple.
2) hinged access door is designed for maintenance on the drive system and the unit is equipped with extended lubrication line.
3) maintenance platform and ladder as free accessories shall be supplied for convenient inspection
4) space saving, compared with other manufacturers, tat is smaller and space-saving
optional accessories
1.electric heater
standard heaters are sized to maintain water temperature at 4°c or above in basin, which shall include electric heater, temperature relay and low water level cut off switch. standard heater design based on ambient air temperature of -18°c
2.electric water level control package
the electric water level control replaces the standard mechanical make-up value when a more precise water level control is required. this package consists of a conductance-acturate level control mounted in the basin and a solenoid valve in the make-up water line.

3.maintenance ladder
inclined maintenance ladder with handrail does not need another safety protection device, it guarantee the safe operation of maintenance personnel, and should be on-site installed.
4.external service platforms and motor davit with base
for external service, access door platforms can be added to the unit when purchased or as an aftermarket item. the service platforms include vertical ladders which are designed for easy field installation.
motor davit with base convenient for mobile motor and drive system, save the cost of renting the crane. transport and separated from the unit, must be on-site installed.
5.access door
inlet grille access door realize easy maintenance work for water dish, water components, filter check, without removing the entire air intake grille.
6.the water basin maintenance platform
part of the box size can be equipped with water basin maintenance platform and ladder, in order to maintain water disc components, vertical ladder must be on-site installed.
7.noise reduction measures
acoustic blanket, constructed of pvc sections, is located in the falling water area of the cold water basin, this option will reduce the overall sound.exhaust muffler assembled with fan cylinder, and complete by factory. exhaust noise will reduce when the fan on operation. standard material is galvanized steel(to follow with 304 stainless steel), including sound insulation outer box and a group of low resistance and noise reduction plate. exhaust muffler and unit transport separately , on-site installation.
8.option stainless steel cold water basin
stainless steel cold water basin is available. this provides superior corrosion resistance over other materials of construction. 
9.vibration cut-off switch
mechanical and electronic vibration cut-off switch could prevent the equipment from breakdown due to excessive vibration from mechanical drive system.
10two speed fan motors
two speed fan motors can provide an excellent means of capacity control. in periods of reduced wet bulb temperatures, the fans can operate at low speed. in addition, the sound levels of the units will be greatly reduced at low speed.
