PMM series Cooling towers
M.I.T.A. S.r.l
Founded in Milan in 1960, M.I.T.A. S.r.l. designs,
produces and sells:
� Open and closed circuit cooling towers for civil
and industrial water
� Evaporative condensers
� Adiabatic coolers and condensers
� Complete systems for industrial cooling.
In over 50 years of business more than 25.000 cooling towers have been installed all over Europe. They
operate in several industrial fields of applications
and they can solve different and complex cooling
problems.
Beyond the choice among different standard units,
MITA provides customised solutions and it is constantly engaged in the study and design of technologically innovative models and solutions, focusing
on the customer’s demands, the energy saving and
the respect for the environment.
PMM series

PMM
Series
PMM
� Open-circuit counter flow cooling towers composed of pre-assembled mod
ules
� Capacity from 2.6 to 14 MW (approximate values
referred to one cell, 5° C temperature range,
19 mm fill pack), modular systems.
The PMM series is proposed in big-size plants.
Each unit is engineered according to the technical
data of the relevant project.
All models are made of factory pre-assembled
modules and components.
This particular design grants a quick and inexpensive
final installation, minimizing the erection times and
costs.
Beside, this the PMM range can be engineered to fit
existing basins or structures in many cases.
PMM series cooling towers can be used in many
fields of application and sectors including:
� Steel mills and metals manufacturing in general
� Energy production facilities
� Chemical and pharmaceutical plants
� Food industry
� Air conditioning systems (for shopping malls,
hospitals, exhibition halls, etc...)
� Technical gas production facilities.

PMM series Cooling towers
Constructive characteristics
� Non-corroding towe
r casing, made up of fibreglass sandwich panels
� Supporting frames made of thick steel, hot dip
galvanized after all the processing
� Fill packs (heat exchanging surface) with different
types of air / water channels, suitable for the use
with various water qualities
� Certified PP Drift eliminators (drift loss 0.01%)
� Water distribution system in PVC / PP / PE and PP
non-clogging spray nozzles
� Each unit can be supplied with one or more
removable walls / access doors in order to
allow quick and easy inspection and maintenance
operations
� Fibreglass fan stack in segments, giving the
possibility to access the fan area in a fast, simple
and safe way
� Axial motor fan system with mechanical gearbox
and transmission shaft, low installed motor
power, low noise levels
� IP56 motor, located outside the air flow, easy to
access.

Why MITA PMM?
� For our actual experience in the field:
`` We are offeri
ng solutions for over 50 years for
civil and industrial water cooling
`` For the quality in the choice of materials, preferring components that are naturally non-corroding.
� For the solutions, designed from time to time according to the customers’ demands and the various
critical issues of systems:
`` For the possibility of adaptation to existing tanks
or structures (replacement of other cooling towers)
`` In case of limited available spaces
`` In case of short plant shutdown for the replacement of existing towers
`` Because of the short erection time with limited
use of workforce for the final installation
`` For the short time from the order confirmation
to the start-up
`` Easy, fast and safe access to internal parts: the
operations for ordinary and extraordinary maintenance are greatly simplified
`` Transportability of pre-assembled modules and
components on standard vehicles
`` Limited use of cranes or forklifts for final assembly
`` Energy savings (axial fans, low rpm)
`` Mu
ltiple solutions to curb the sound levels
`` Cooling of different types of water
`` Maximum operating flexibility to optimize the
system according to the different loads and environmental conditions.

Feasibility and engineering
process analysis
�
For every order a static and dynamic
structural analysis is carried out,
considering seismic factors, wind thrust,
snow load, etc.
� Computer tools, specific selection software
to calculate the heat exchange surface,
the impellers and motors used to achieve
maximum efficiency and energy savings
� Wide range of customized solutions and
optional items
� Pre- and after-sales technical inspections
� On-site supervision and support.
Noise impact assessment
� MITA technical department makes use of a computer program
for its cooling towers especially developed in cooperation
with a company experienced in developing noise reduction
solutions and vibro-acoustic analysis software
� The measurements of so
und levels were made in cooperation
with an acoustical consulting firm enrolled in the “Assoacustici”
register
� All values related to noise emissions are measured and
calculated according to ISO 3744 and EN 13487 standards.

PMM
Series
All PMM series cooling towers are assembled with different heat exchange fill packs
selected according to the type of water to be cooled and the customer’s needs.
The fill packs used by MITA (internally tested in the own test station) are composed of
self-extinguishing PVC sheets or thermoformed PP, available with different geometries
depending on the characteristics of water:
� 19 mm (PVC or PP*)
panels for industrially clean water, with maximum temperatures of +55 °C (PVC) and peaks up to +80 °C (PP)
� GS-L (PVC also available for high temperatures)
panels for dirty water, developed by MITA to provide maximum heat transfer by combining an effective
splash effect to a film component
� GS (PP)
grids for very dirty water (suspend
ed solids and colloids with a diameter <200/300 microns, concentration
<1000 mg / l) and with a maximum peak temperature of +80 °C.
