Mixed structure casing
Construction materials:
• hot-dip galvanized steel (internal and external support structure), sandwich panels in fibreglass of 22 mm thickness, top-plate/covering supports foot-loads
Characteristics:
• high thickness (5-7 mm) of the profile channels of which the structure is composed, hot-dip galvanized (600 g/m2) after fabrication
• internal and external surface protection of the panels with a gel-coat resistant to UV radiation, hot and cold water, abrasion caused by weathering and by chemicals
• non-corroding
Fibreglass sandwich panels means
• double wall of fibreglass laminate between which is interposed the expanded support material
• only the inside surface of the side wall is in contact with the water to be cooled
• good sound absorption effect on the internal falling water noise
• 2 completely removable side-walls on the opposite side of inlet water are included instandard supply
Gearbox and shaft driven axial fan
Construction materials:
• hot-dip galvanized steel (electric motor support), extruded aluminium alloy with propeller profi le(fan blades)
• the drive system is composed of a hollow shaft without intermediate supports with flexible “lamellar” joints in 316 stainless steel (on request a carbon-fibre shaft can be supplied)
• the fan stack is entirely manufactured infi breglass, with fl anged segments for easy on-siteassembly
Characteristics:
• high performance, low electrical power input
• electric motor is positioned outside of the humid air stream
Fill pack (or heat exchange surface)
Construction materials:
• self-extinguishing PVC
Characteristics:
• 20 mm wide flute (air/water channels), reinforced top layer, reduced fouling
• high air/water heat exchange efficiency.
NOTE: all the models can be transported in several factory pre-assembled sections (also in container), whilst their subsequent site assembly is extremely simple and rapid.
