air handling units technical description Modulys® TA 350 TAC 3 ECM ➤ Dimensions, reservation and weight • he dimension features of Modulys® TA 350 TAC 3 are identical T to those of Modulys® TA 350. • For more information, please go to page 463 of this Guide. low profile air handling unit with constant air flow or constant pressure ➤ eatures (electric, acoustic, various...) F • otor ECM : an intelligent motor for an intelligent fan M - otor of continuous supply type and with permanent magnets, M with alternative supply 230 V, 50 or 60 Hz. - otor ECM equipped with a microprocesser (fixed to the M motor), controling the functioning of the motor (commutation of the rotor). - icroprocesser capable of precisely communicating the instant M value of it’s functioning point. modulys® ta 350 tac 3 ecm ➤ advantages • aintains the chosen air flow, whatever the evolution M of the pressure drop of the network (serie TAC 3 CA). • aintains the chosen pressure, whatever the evolution M of the pressure drop of the network (serie TAC). • High efficiency of the motor. • otor ECM : extremely high efficiency M - Very high efficiency of motor, whatever its rotation speed. - fficiency is between 60 % and 85 % for a rotation speed E between 300 and 1800 revolution per minute. • Energy saving. • Removable regulation in TAC 3 Full. ➤ range • ersion TAC 3 CA : constant flow V - nables to choose a flow among a finished serie of possible E flows. The fan is auto-piloted as to maintain the flow, independently from the pressure drop of the network. - Application : constant flow chosen by dip-switch. • ersion TAC 3 FULL : choice of regulation V 1. egulation CP : constant pressure R - aintains the defined nominal pressure, independently from M the pressure variations of the network. - Application : ventilation in constant flow. 2. egulation LS : link 0/10 V R - nables the connection of the constant air flow to maintain E an analogical entrance signal 0-10 V. - Application : constant flow variable via an external signal 0-10 V. 3. egulation CA : constant flow R - nables to choose a flow among a finished serie of possible E flows. The fan is auto-piloted as to maintain the flow, independently from the pressure drop of the network. - Application : constant flow chosen by dip-switch. ➤ application • ir treatment in installations needing the placing of an air A handling unit with a small height and of which the flow must stay constant or of which the pressure must stay constant. • nit : U - or construction and composition of the unit, f go to the features of Modulys® TA 350, p. 463. • echnology TAC : control of air flow or pressure T - ased on the construction of aeraulic models, and algorithm B calculations enabling the use of the informations of the ECM motor. - ntegrates the instant calculations models of the functioning I point of the fan, enabling the control of the fan in constant floor or constant pressure. • echnology TAC : energy savings T - pecific motor based on the saving of electric consumption. S - onsumption compared to a standard centrifugal fan is reduced C from 40 % to 50 % according to the application point and the type of regulation considered. ➤ option • ossibility of piloting the fans via a computer network.
