MCC MCE Non-corroding cooling towers MCC MCE Series Evaporative condensers Closed circuit evaporative cooling towers Series MCC and evapo MCC Series: closed circuit evaporative cooling towers The MCC series closed circuit evaporative cooling towers are employed as an alternative to open-type cooling circuits with heat exchangers, in those cases in which the cooling ﬂuid for the user’s equipment (generally water or water with glycol) must maintain its chemical and physical characteristics constant over time and unpolluted by external elements. In fact the ﬂuid to be cooled circulates within the tubes constituting the heat exchanger coil placed inside the cooling tower: the coil, in turn, is continuously wetted by the water, contained in the basin of the tower, which is sent to a spray system with nozzles via the appropriate pump. Thanks to the combined effects of the evaporation of a small part of the spray water and of the turbulence created inside the tubes, the cooling of

the ﬂuid, which can hence be returned to the user’s equipment, is achieved. MCE Series: evaporative condensers The MCE series evaporative condensers can be employed in air conditioning and industrial refrigeration installations, representing in their operation an alternative to the classical water-cooled condenser with evaporative cooling tower or systems with aircooled ﬁnned coils. The refrigerant gas to be condensed is fed to the upper header of a coil of smooth-surface tubes which, continuously wetted by water appropriately sprayed and in contact with an adequate countercurrent airﬂow, permits the progressive condensation of the gas. The gas, thus cooled and condensed to the liquid state, can be returned via the lower header to the installation. Hence the evaporative condenser, in the context of water-cooled condensing systems combines the “open circuit cooling tower/S&T condenser” system in a single and compact unit exploiting, inside the unit, the forced evaporation o

f a small quantity of the recirculating spray water to achieve the heat load rejection which is necessary to condensate the refrigerant gas. Constructional features Fitted with one or more axial fans according to the model, the MCC and MCE series are built with a strong supporting structure in hotdip galvanised steel and side walls made of ﬁbreglass sandwich panels. The internal heat exchanger is composed of smooth-tube coils, fabricated in compliance with PED directive 97/23/EC for MCE series only. The standard conﬁguration is completed by the water collecting basin and the fan cylinders made entirely of ﬁbreglass (FRP). The range includes 36 models suitable for installations with requested refrigeration loads between approx. 80 and 1500 kW. orative condensers Series MCE MCC MCE Series Structural characteristics 2 3 1 4 7 6 5 1 Structure and main casing Construction Materials: steel supporting structure, hot-dip galvanised after fabrication, sandwich panelling in 22

mm thick ﬁbreglass. Characteristics: • optimum mechanical resistance • good sound-absorption properties • non-corroding • easy internal inspection (with optional man holes). 2 Multi-blade axial fan Construction Materials: hot-dip galvanised steel (support), electric motor, plastic (fan blades), stainless steel (protective grid). Characteristics: • high performance, low absorbed electric power, fan directly driven by the motor • safety function of the protective grid unaltered over time • easy blade replacement. 3 4 5 Water distribution system Construction Materials: normalised PN 10 PVC pipes, polypropylene tangential nozzles. Characteristics: • non-corroding • uniform and complete spraying of the coil, full-cone spray • exclusive MITA-design nozzles: the water ﬂow is induced in the diffuser cone solely by the tangential connection to the main body of the nozzle, hence there are no internal parts which could give rise to obstructions.
