PRODUCT DATA SHEET
CONSTRUCTION FEATURES
TAP-type machines, open-circuit evaporative towers with prementi axial fans, are built and assembled in accordance with our ISO 9001 certified quality system
MAGNELIS
All our machines are built as standard in Magnelis®, it is an eco-sustainable alloy made up of 93.5% zinc, 3.5% aluminum and 3% magnesium. The percentage of magnesium allows the self-repair process after cutting and punching operations and protects deformed surfaces. Another characteristic is the corrosion resistance, superior even in environments rich in chloride and ammonia. The maximum workability and greater resistance, compared to other materials, allows the use of a smaller quantity of metal coating and therefore a greater lightness of the machines.
STRUCTURE & ASSEMBLY
The standard unit is built with Magnelis® (steel, zinc, aluminium, magnesium) ZM310 type sheet metal panels to ensure maximum surface protection empirically comparable to a galvanized sheet metal with over 1000 g/m2 of zinc. The individual panels, following the cutting and folding phase, are assembled with AISI 304 (A2-70) or on request AISI 316 (A4-80) stainless steel small parts and highly adhesive butyl mastic gasket reinforced with polyester mesh inside to guarantee great shape stability and resistance to temperature variations. No welding is required in the various stages of assembly of the structure (self-supporting). The color of the sheet metal type Magnelis® is RAL 9006.
WATER COLLECTION BASIN
The basin section is built with a thick Magnelis® ZM310 sheet metal structure and is equipped with a removable anti-fog filter. cavitation in AISI 304L (to protect the primary circuit pump) and water make-up valve with brass/stainless steel body and floating sphere in stainless steel or polypropylene. All machine connections are made of galvanized steel (AISI 304L on request).
FILLING
The fill or exchange pack is made of PVC(PP upon request) with proprietary geometry design. The filling standard is type W1300 and on request, depending on the characteristics of the water to be used it can be type W2000 or for particularly dirty water filling W2700 is available. The geometry used is such that the heat exchange surfaces between air and water are maximized.
WATER DISTRIBUTION SYSTEM
The water is uniformly distributed by a piping system inside the machine made of PVC with a sheet metal distribution box Magnelis®. The spray nozzles are of the non-clogging type, of medium and large diameter, in ABS and easily replaceable in case of maintenance. The pipes that connect the recirculation pump with the internal ramp are made of PVC, easily removable for possible cleaning of the circuit, in accordance with the latest health provisions (anti-legionella).
VENTILATION SYSTEM
(MOTORS + FANS)
The fan unit is placed in the basin section, housed on a sturdy galvanized steel structure fixed to the frame which
supports the entire unit. The axial fan is made with high efficiency glass fiber reinforced polypropylene (PPG) blades, aluminum hub, galvanized steel bush and bolts. The fan protection net will be made of galvanized steel. The motor, efficiency class IE3, with tropicalized IP56 mechanical protection, insulation class F, continuous duty S1, shape B3 and automatic condensate drain, is keyed directly to the axial fan (direct coupling). The motors are suitable for being coupled to frequency variators (VSD-Inverters) 30-50Hz. The engines comply with CE 2019/1781 regulation. The electrical connection terminals and the connection of any optional extras (anti-condensation heater and PTC thermistor) are enclosed inside the terminal box of the electric motor.
DROP SEPARATOR
Drift eliminators are made in PVC (PP on request) and divided in various sections to facilitate their removal in case of replacement or inspection of ventilation and water distribution system. The used drift eliminators allow a passage of drops equal to 0.001% of the droplets present at the entrance, removing water loss, potential aerosols drift that might contain Legionella bacteria.
TEST
All components are supplied assembled. Each unit, before delivery, is subjected to hydraulic testing, to ensure that there are no water leaks in the tank, and electrical to check that the electric motors have an absorption in line with the plate data.
