MANUFACTURING FEATURES
CHASIS
• Internal support structure in hot-dip galvanized steel profiles Z140; construction in accordance with EN1886, mechanical resistance class D1.
• External casing made of sandwich panels,25 mm thick and in 6/10 thick sheet steel.
• Internal sheets hot-dip galvanized Z140, external sheets pre-lacquered RAL 9010 and covered with a protective PVC film.
• Internal insulation using high-density polyurethane foam (40 kg/m³). Airtightness guaranteed by an adaptable and resistant neoprene gasket.
• Opening panels, tightened by push screws that ensure adequate and constant pressure on the sealing joints.
• AISI 304 (EURONORM 1.4301) stainless steel condensate collection tank, internally sloped to facilitate drainage, in correspondence with the areas subject to condensation.
HEAT EXCHANGER
• Aluminum counterflow heat exchangers, whose efficiency certified by Eurovent exceeds the requirements established by the ecological design regulation No. 1253/2014/EU.
• Sized to achieve the best balance between heat recovery efficiency, pressure drops and electrical consumption of the fans.
• The heat exchangers also integrate a bypass damper (100% of the air flow) with automatic control to achieve the free-cooling and free-heating functions provided for by the aforementioned Ecodesign regulations.
• Inclined set to facilitate the discharge of condensates and simplify the start-up of the machine.
FILTERS
• Each OREQA series recovery unit is equipped with 1 ePM1 50% (F7) extraction filter and another ePM1 50% (F7) supply filter, both mounted on guides with gaskets for effective sealing and placed upstream of the internal components to guarantee adequate protection.
•Optionally, an ePM1 80% (F9) filter can be requested in supply side.
MOTOR-FANS
• Centrifugal fans in galvanized steel, independently controllable. With forward curved blades, aerodynamic profile, statically and dynamically balanced. Directly coupled to electronically commutated type motors (EC brushless), thermally protected and regulated by a 0-10V modulating signal.
ELECTRONIC CONTROL
• Supplied with an advanced electronic display, which includes temperature probes in the external air intake and the ambient air intake, which supervises their operation. The user interface consists of a remote control panel with an LCD screen.
•There are 3 control modes, all with Modbus communication protocol to integrate the unit in the most modern home automation systems through the RS485 serial port, supplied as standard.
-Control BASIC
-Control EVO COP (Constant pressure)
-Control EVO CAV (Constant airflow)
BYPASS
• Automatic by-pass damper 100% of the airflow rate.
RANGE
• 7 construction sizes.
• Circular connection from Ø150 to Ø315mm, depending on the model.
• Vertical and horizontal configuration.
• Flows up to 400 and 4.000 m³/h.
• Factory configurable only. Standard configuration H2 and V1.
• 3 controls with Modbus.
APPLICATIONS
• Designed for mounting in a false ceiling, in residential and commercial environments.
• For outdoor use, the installation of a weather protective roof is mandatory.
• In full compliance with the requirements of Ecodesign Regulation No. 1253/2014/EU, in force since January 2018, the devices in the OREQA range guarantee high standards of comfort and health in enslaved environments, optimizing the general energy balance and against a particularly low power consumption.
• Suggested minimum outside temperature of -5°C.
