The TAT series are dedicated to every industrial sector with a modular conception. These models are characterized by SCAM T.P.E. S.r.l. well defined standards and are supplied with a structure preassembled and welded in continuous with a polyurethane coating and  epoxy-bituminous according to ISO 12944-5:2007. The stacks and the collecting basin are supplied with a treatment carried out on processed carpentry SCAMBOND/STD, a protective cycle carried out on processed carpentry of polyurethane type for external surfaces and epoxy-bituminous for internal surfaces, according to EN ISO 12944-5:2007(E) standards. This type of towers has dimensions compatible with road and ocean transport. The ordinary maintenance is ensured by oversized ispection doors placed for every cell/fan unit. The fan units are planned for a long life and with components of utmost quality, with a very easy maintenance program.



For TAT series of classic induced execution towers, the choice concerning the type of fan is almost obliged. The electric motor is placed inside the saturated air flow, the motor foreseen for utilization in saturated ambient, in hard working conditions. On the same an axial fan in reinforced polypropylene (or FRP) or in aluminum alloy is placed. The stacks of pyramid truncated shape allow a dynamic pressure recovery and a consequent reduction in the energy consumption.

Axial fans: With multiblade solution, have the function to ensure the cooling tower with the necessary air volume. The axial fan is placed on the cell high section (levelled with tower decking) and it is directly coupled  on the motor drive shaft. The high efficiency blades are of asymmentric profile “NACA” aeronautic type, balanced with “PALA MASTER” system. All the blades are equipped with the adjustable incidence solution with still fan in order to better optimize the tower performances and the electric power consumption. The constituent materials are the galvanized steel for the hub and the 6060T5 aluminum (FRP or PPG) for the blades.     

Electric motors: are planned for severe conditions with continuous working type S1 asynchronous three-phase TEFC with SKF bearings type 2RSC3 with watertight oiled “for life”, IP55 + SCAM T.P.E. S.r.l. specifications ensuring durability. They are placed inside the flow crossing the truncated cone stacks for a better fluo-dynamic distribution. The electric motors frames are designed to transfer the dynamic loads to the cooling tower structure, minimising vibrations and allowing an easy and intuitive maintenance. All the rotating parts outside the stack are protected against accidental interferences in accordance with the most updated safety standards.

Unexpected vibration switch: All the fan cells/groups  are equipped with a switch cutting the motors power in case of excessive vibrations and it is contained outside the fan duct on every stack of the tower. This device is already wired to the external Junction box on which the power supply is grafted.



All the mechanical groups in each cooling tower cell have an high thickness steel stack with SCAMBOND/STD protection. Each stack has a circular inlet junction and a pyramidal section: the outlet section is designed to recover dynamic pressure obtaining an high efficiency of the axial fan. The stacks are fixed to the structure through dedicated bolts by securing them to the tower planking level.



Inside the cooling tower upper section is placed the distribution system of “pressure” type. It is composed by a main channel connected to secondary ones whereon the spray nozzles are placed to ensure a water uniform distribution upon all the dispersion section.   

The a.m. nozzles are of Eco type. This innovative spray nozzle has been designed to reach the following main goals:  

  • - Large square water distribution (approximately 1 m2) in order to avoid any possible overlapping of the nozzles distribution on the same dispersion surface.
  • - Uniform hydraulic load in order to avoid any air bypass where the load is low and not equally supplied.
  • - Lower distance between nozzle and filling  (600 mm) in order to reduce the pumping elevation.
  • - Low pressure of utilization in order to reduce the pumping elevation.
  • - Self cleaning surface by means of dedicated hydraulic impeller.   
  • - Anti clogging. 



The structure is characterized by painted steel profiles with continuous welding.  Stainless steel bolts, lightness and main structure solidity  are the main features. This structure typology envisages the utilization of lateral cover panels realized in stainless steel with SCAMBOND/STD protection cycle.



SCAM T.P.E. towers may be proposed with structure and paneling completely in stainless steel (304 or 316 according to the requirements)  where the project characteristics make necessary to use highly corrosion resistant metallurgies.
