3 UR Heat recovery unit These units allow to extract a certain amount of exhaust air from the room and supply an equivalent quantity of fresh air. A crossflow aluminium plate exchanger assures an efficient heat exchange between exhaust and fresh air: therefore the fresh air is pre-heated or precooled according to the seasons. The supply air is filtered before entering the heat recovery exchanger that is protected with a synthetic filter also at the exhaust air side. The supply air can optionally be re-heated with a hot water coil or with an electric coil. Features 7 sizes are available: UR: standard version UR W: same as standard version and equipped with water heating coil with copper tubes and 3 rows aluminium fins. Not to be used with chilled water UR E: same as standard versions and equipped with electric heating coil with aluminium fins and double safety thermostat Double suction centrifugal fans coupled directly to the electric motors, equipped with adjustable speeds via an electronic control to vary the flow rate G3 class synthetic filter on the air outlet Aluminium plate reheater housed in the condensate tray that is easily removed from the bottom G3 class synthetic filter on the fresh air intake Self-bearing panels made of galvanized plate with injected polyurethane insulation and thickness 0.8 in. Galvanized condensate tray Fans can be inspected from the bottom Filters can be removed from the bottom for cleaning or replacement Two versions available for horizontal and vertical installation (it is not possible to install the cooling coil accessories and silencers for the vertical installation) Electronic Regulator with Slave Application allowing continuous variation of rotation speed and air flow rate 3

7 NEW URX CF Heat recovery unit with refrigerant circuit. Air flow from 750 to 3,300 m 3 /h. R410A The URX_CF series is the mono-bloc solution designed for the installation requirements typical for public spaces like bars, restaurants, offices, meeting rooms. The URX_CF units combine in one mono-bloc unit, besides the fan, filter, and heat recovery sections, a heat pump refrigerant circuit with scroll compressors of high output and low noise. The supply air is heated or cooled, based on the season, through the heat pump refrigerant circuit located within the unit and charged with refrigerant R410A. All this allows to have a complete unit, with the automatic operation in each season and capable of combining the required space ventilation requirements with efficient heat recovery. The careful design of the machine combines very compact dimensions, which permit easy installation in false ceilings, with an excellent accessibility for maintaining all the internal components.

11 NEW URHE CF High efficiency heat recovery unit with refrigerant circuit without an external unit. Air flow from 588 to 1942 cfm R410A TECHNOLOGY HIGH EFFICIENCY The units from the URHE_CF series represent the high efficiency solution to satisfy the temperature and humidity comfort and ventilation requirements in air conditioning systems that serve public spaces and the commercial sector, such as offices, bars, restaurants, etc. The URHE_CF units are particularly efficient machines in that they use a high efficiency cross flow plate heat exchanger of high capacity combined with a heat pump refrigerant circuit operating with refrigerant R410A. The use of a high capacity cross flow heat recovery unit permits a significant reduction in the operating time of the refrigerant circuit throughout the year, thereby reducing to the minimum the electrical energy consumption. The small unit dimensions allow an easy installation even in false ceilings, allowing excellent accessibility for the maintenance of all the internal components. The numerous accessories available on request, for example the high efficiency compact filters, the hot water coil or the silencers, complete the functions of the machine which is usually combined to an air conditioning system. Characteristics VERSIONS 4 sizes available in horizontal configuration for ground or ceiling void installation. Unit complete with temperature controller and ready for installation. STRUCTURE AND PANELS: Structure in aluminium profiles with glass fibre reinforced nylon corner pieces. Sandwich panel 1 in thick with galvanised steel for the internal surface, prepainted for the external surface with injected polyurethane insulation (density 2.62 lb/ft3). HEAT RECOVERY: Cross flow plate heat exchanger in aluminium optimised to ensure high outputs. PLEATED FILTERS: Class G4, 80% gravimetric efficiency according to EN 779, thickness 1.9 in located before the heat recovery both in the supply and return air flow. CENTRIFUGAL FANS: High pressure forward curved impeller directly coupled to the motor. The air flow is maintained constant by the use of an electronic controller.. REFRIGERANT CIRCUIT: Heat pump with refrigerant R410A, complete with high efficiency low noise rotary or scroll compressors (depending on size), 4 way refrigerant cycle reversing valve, evaporator coil, condenser coil, liquid receiver, thermostatic expansion valve, liquid sight glass, filter drier, high pressure pressostat, low pressure pressostat, safety valve, bypass valve (for the smaller sizes). ELECTRICAL PANEL: The unit is provided with an electrical panel complete with power and control section (including the control for the 3 way valve for the supplementary hot water coil and associated actuators), ensuring the control of all the refrigerant circuit functions.
