HEAT RECUPERATORS WITH AIR-AIR CROSS FLOW
OVERVIEW :The XRC series of heat recuperators are fitted with a highly efficient air-air heat exchanger that makes it possible to reuse a significant amount of the heat present in the extracted air. It is therefore suitable for all those installations where a significant amount of heat can be recovered thereby making energy savings, such as in ventilation systems in shops, offices, catering premises, bars and restaurants.CONSTRUCTION DETAILS:- The XRC model is made with an aluminium profile structure and box shape panels of pre-varnished galvanized steel, internally isolated with glass wool having an average thickness of 15 mm, ideal to guarantee the maximum results for acoustic and thermal isolation with density greater than than 120 Kg/m³. - Static type heat exchanger, highly efficient, made with aluminium plates using cross-air flows kept separate by a suitable sealing.- G4 class supply and extraction filter elements, wavy model, in polyester fibre with a metal frame and electrically welded containment net with purposely ideated slots to facilitate maintenance and periodic substitution.- Supply and extraction centrifugal ventilators with double aspiration removable on each side of the unit for frequent maintenance.- One or three speed electric motors directly coupled, usually available in stock 1 speed version. - On board terminal for electrical connections and ventilators control.- Condensation collecting basin in galvanized steel with condensation discharge.ACCESSORIES :Cooling or heating batteries.Speed regulator and switch.

HEAT RECUPERATORS WITH AIR-AIR CROSS FLOW
COOLING SECTION :Allows cooling and the possibility of dehumidifying the air on exit from the recuperator unit. An exchange battery is used with copper tubing and and aluminium pack with a collection basin in galvanized steel. The unit is boxed in a special aluminium profile casing and a dobble panel, sandwich, system insulated with glass wool. The characteristics of the frame allow the unit to be fixed into place in linear square air ducts.
Example of connection between recuperator and battery unit. Duct connectors are not supplied.
WATER COOLED BATTERIES XRC e XRCE
Sizes chosen with the following criteria: injected air at 29 °C dry bulb, U.R. 50%, water temperture of 7/12 °C.

COMPLETE CONTROL SYSTEM
HEAT RECUPERATORS WITH AIR-AIR CROSS FLOW SERIE
XRCCOMPLETE CONTROL SYSTEM
The heat regenerators of the series XRC have an efficient control system that allows the control of two single-phase motors to a variable speed up to a maximum of three speeds or two three phase motors of varying power, while also allowing the modular control of temperature is for three-way valves that electric coils.
TECHINICAL CARATTERISTICS OF THE BASIC MODULEThe control panel CRK has a sealed containment box with protection degree IP65 in white PVC, and is installed on the machine, while the control is via a remote keyboard with BUS. It is prepared for the management of the temperature control system at a fixed point, for the management of the antifreeze safety of the battery to heating water, for the warning signal for the dirty filters, for the signal of the presence of flow and other external safety as the signaling plant status. Is supplied or installed complete with diagrams, instructions for use and conformance claims. The testing of the control panel, if installed by our staff takes place at the factory, otherwise if required will arrange for supervision of testing to be agreed with the technical department. The dimensions of the control panel are 410x285x140, while the size of the command are 120x70x15. Part of Power:• Circuit breaker for motor protection• Fuses for transformer protection• Transformers for the auxiliary circuits and modulating 230V-0/24VacCommands front door:• Remote terminal with LCD display in the container wall type LX1Control Regulations:• Electronic control type NK109:- The ambient temperature- Ambient humidity- Free cooling The quality of air CO2 (prepared)- The quality of air CO2 (prepared)

CONSTRUCTION CHARACTERISTICS FOR STANDARD BASE MODEL:The COMPACT command panel has a tin containment casing with a protection rating IP55 in PVC all in white. This is installed on the side of the unit. The control is done via a remote and/or infrared signal keypad. It is set up to manage the thermal regulation fixed point system, to control the anti freeze danger of the cooling and heating battery, to indicate when the filters need maintenance, for the presence of air flow and other external warnings like for example the general status of the set up.The unit is delivered complete with power supply connection diagrams, instruction manual and conformity declarations. The testing for the control panel is done at the factory if installed by our technician or our technician can be present if installed by a third party.The dimension of the control panel are 300x300x150mm and those for the control are 153x110x66mm.
HEAT RECUPERATORS WITH AIR-AIR CROSS FLOW
The XRC series heat recuperators make use of an efficient system that can control two single faze motors at a variable speed, up to a maximum of three speeds. Alternatively two different power tri-faze motors allow a modular control of the temperature, both for three way valves and electric batteries.
