The PME-E series is suggested for medium and large size plants.
All models are totally pre-assembled at our factory.
– Axial motor-fan with direct coupling, low installed power, low noise levels.
– Support structure in hot dip galvanized steel after fabrication.
– Distribution system in PVC, PP or PE equipped with wide non-clogging PP spray nozzles.
– Fill pack with different kinds of air/water channels, suitable for the use with different water types.
– Certified PP drift eliminators (entrainment 0.01%).
– Tank with sloping base entirely made of fibreglass.
– Capacity: from 860 kW to 2.6MW (indicative capacity referring to a machine, thermal gradient 5°C).
LOAD BEARING STRUCTURE in high thickness, hot dip galvanised steel (galvanisation process in accordance with UNI EN ISO 1461-99 standard, thickness not inferior to 80 micron).
CASING consisting of 22 mm thick polyester resin sandwich panels reinforced with fibreglass with gelcoat for UV-protection.
Sealing between the load bearing structure and the panels is guaranteed by a special bituminous sealing gasket.
The tower casing is equipped with FRP man-sized access door(s) in hot-dip galvanised steel after fabrication frame to allow easy inspection and access to the inside of the tower.
Totally removable side-wall(s) (each 2100x1760mm), located on the short side(s) of the PME-E units, can be supplied as an option, to simplify routine maintenance operations to the tower internal components.
PERIMETER FRAME with FILL PACK SUPPORT in high thickness, hot dip galvanised steel (galvanisation process in accordance with UNI EN ISO 1461-99 standard, thickness not inferior to 80 micron). It is located and fixed to the base of the tower body to form a strong structure.
Hot dip galvanized steel after fabrication metal supports are fixed to the frame to support the fill pack.
NUTS AND BOLTS in stainless steel AISI 304.
FAN DECK entirely in FRP, adequately structured and reinforced, with gelcoat for UV-protection.
Every fan deck is equipped with an adequately sized FRP fan ring, with such a shape as to minimise vortex and air pressure drops. The axial fan, directly coupled with the electric motor, is located inside the ring.
AXIAL FAN SYSTEM made of:
FAN PROTECTION GRID in stainless steel AISI 304
ELECTRICAL ISOLATOR (lockable), located on the tower casing, for emergency stops, box IP65
DRIFT ELIMINATORS, high efficient, certified by EUROVENT, consisting of three folds PP sheets, thermoformed under vacuum and welded together to form panels of such shape and size as to guarantee maximum efficiency of droplet separation from the airflow drawn by the fan.
WATER DISTRIBUTION SYSTEM made of PN 10 pipes and connectors complete with flanged connection, entirely made of plastic material, consisting in a main header and branches with non-clogging, static type, spray nozzles.
This system grants a perfect and even perfusion of the fill pack, and therefore an optimal performance.
The non-clogging nozzles are made of isotactic polypropylene with full cone (120° angle) spraying.
FILL PACK (or heat exchange surface) consisting of PVC or PP sheets, thermoformed under vacuum and welded together (air/water channels of different kinds suitable for the cooling of different water types).
The shape and the size of the fill pack optimise the contact between air and water, and therefore the heat transfer process.
WATER COLLECTION BASIN entirely in fibreglass reinforced polyester (FRP).
As standard the basins are equipped of a sloping base with rounded corners for easy cleaning operations, complete with flanged water outlet connection(s), drain, make-up and overflow connections.
The basin is a separate component which is fixed to a hot-dip galvanised steel after fabrication frame, which includes the removable FRP louvers.
