NC-ST Design Features

The NC and ST water cooling towers are derived from a common standard and are supplied pre-assembled,
since their dimensions are compatible with transportation by road, avoiding the separation between the
cooling tower body from the ventilation group.
For oversea shipping a special size suitable for container packing is also available.

> FILLING
STT-STG Resting system
The splash grids are assembled on several overlapping layers, and rest on a strong lower bearing frame. Due to this supporting system, the splash grids could be replaced or combined with a film filling.
NCP-NCG  Suspended system
The splash grids are assembled on several overlapping layers, and are suspended by stainless cables to an upper frame.

> STRUCTURE
STT AND STG MODELS
Every module  is composed  of a main cooling unit, one or two ventilating group and an additional separated cooling unit. The structure is composed by a strong welded frame and assembled casing. The top of the cooling tower is flat and suitable to walk on.
The module can be completed with the air inlet section and the cooled water basin.

> FAN UNITS
The ventilation is operated by induced draught, characterized by fans in drawing position.
The electric motors are equipped with all the special protections for the operation in presence of water droplets and moisture; the fan is assembled directly on the motor shaft and the whole group is assembled on a monolithic structure which can be easily disassembled. The fans have an high efficiency wing profile .The ventilation duct is protected by a safety metal grid.

> DISTRIBUTION SYSTEM
The water to be cooled enters into the module through a single flanged connection. The nozzles are assembled through a threaded connection and their dimensions are factory selected to suit the design water flow and guarantee the best performances.
The passages size are large, in order to avoid any risk of blockage.

> DRIFT ELIMINATORS
The drift eliminators are made of PVC/PP sheet modular elements. The efficiency of the eliminator is very high and it limits the water leaks due to dragging to less than 0.005% of the circulating range.

> ENVIRONMENTAL IMPACT - LOW NOISE MODELS  

The sound power level generated by the NC - ST cooling towers is suitable for the installation in most environments. In case of very strict requirements, special models and execution are available, which are characterized by differentiated and very low level of sound emissions. ILMED is in position to propose many technical solutions, and to combine them together in order to attain the best result
