UTW 63÷544MODULAR DUCTABLE TERMINAL UNITS.FROM 4,6 kW TO 43 kW.UNIT DESCRIPTIONThe modular <strong>water</strong> <strong>terminal</strong> <strong>unit</strong>s of the UTW series are the ideal solutionto meet the air treatment needs of systems including distributionthrough ducting or directly into the room and installation in false ceilingsor in serv<strong>ice</strong> rooms.If equipped with a <strong>water</strong> cooler, they generate cool air silently and immediately.Otherwise, during the winter, if combined with a heating systemwith boiler or heat pump, they deliver warm air to satisfy the heatingneeds of households and the serv<strong>ice</strong> industry alike. A filter, which absorbsand retains dust in suspension, allows to keep the air quality at asuitable level, and its easy removal enables continuous cleaning cyclesto be carried out which are particularly important in order to guaranteesuitable hygiene standards in highly frequented rooms.This product range, available for 2- and 4-pipe systems, is complete withvarious accessories such as: outdoor air intake plenum, mixing sectionwith dampers room delivery plenum for flexible ducts and resistanceheating section. These <strong>unit</strong>s can be combined with the innovative monitoringand control system CLIMAFRIEND which allows to program andobtain a level of comfort intuitively and efficiently.VERSIONSUTWBase <strong>unit</strong>FEATURES• Structure in galvanized sheet (63÷274) or in prepainted metalsheet (333÷544), entirely lined with heat/sound insulation material.• Centrifugal type fan with double intake, statically and dynamicallybalanced to reduce vibration and noise to a minimum, directlycoupled on single-phase 3-speed electric motor (63÷274)or with belt and pulley transmission, connected to 3-phasesingle speed electric motor (333÷544).• Heat exchanger in copper tubes and aluminium fins, completewith air vent and drain pan.• Air filter made of recyclable synthetic material class EU3;inspection is foreseen from the bottom part (63÷274) or side part(333÷544).• Air bleed valves these are found on the <strong>water</strong> connections ofthe coil and make it possible to bleed air from the coil.• Electrical panel comprising a <strong>terminal</strong> board for wiring to roomcontrol panel and power supply.ACCESSORIESLoose accessories:AF Filter sectionSF Supply frameGRI/R Intake grille+air filterBM Supply grille with adjustable finnsPR Intake plenumMB Mixing box with damperSP Supply plenumP3Supply plenum for flexible ductsWS Section for 4-pipes systemEH1 Electric heater sectionEH2 Electric heater sectionDPG Intake/supply panelSM Servomotor for damperVR Fan speed controlDRM Control panelDRA Automatic control panel166
