Description
Altair HR is a unit of controlled mechanical ventilation with high efficiency specially designed for ventilation of small, medium and large commercial buildings.
Altair HR enables an almost total recovery of the calories on the air extracted through the excellent performance of 92% of the heat exchanger to transmit air breathed new.
Available with standard adjustment CTR and evolved CTRX
HR units with horizontal installation
- Capacities from 330 460 to m3/h
- Countercurrent heat exchanger, high efficiency, PP
- Filters classified according to EN 779: G4 in F7 extraction renewal
- Electronic fans EC plug fans with high efficiency (ERP 2015)
- Automatic defrost function of the heat exchanger
- By-pass for the exploitation of external climatic conditions
- High efficiency in recovering sensible heat (up to 93%)
- Plug-n-play connection to the mains
Compact ventilation system
Altair HR is realized with a self-supporting sandwich panels, 23 mm thickness, insulated with polyurethane foam.
The outer part of the structure is made of sheet metal gray color plastofilmata, while the internal part of the panels is Aluzinc (material that provides high resistance to corrosion).
The interior of Altair HR is in expanded polypropylene, a material that ensures a high degree of thermal insulation between the air flows.
Access to filters, fans and the heat exchanger, is facilitated by the removable front panel that allows you to operate free from any obstacle.
evolved command repositioned
And 'possible to combine the mechanical ventilation system Altair HR the advanced control with an elegant display that can be installed in an area convenient for the user control.
The menu is easy to use for basic configuration of the unit (manual or automatic, programming time slots, setting temperature and humidity).
Low noise
The acoustic structure of Altair HR units ensures absolute quiet operation.
The maximum efficiency and quiet operation of the ventilation system is achieved thanks to a complete air distribution system with silencers output and following the recommended design criteria.
The extensive use of sound absorbing material together with the use of oversized fans, reduce the level of sound power at exceptionally low levels.
Property for Class A
The installation of a high efficiency heat recovery unit housing allows access to energy classification Class A, Thereby increasing the value and creating the conditions for it can be preserved over time.
Install a heat recovery Altair, then, in addition to ensuring healthier environment, it is also on the property investment.
In CTR CTRX unit and the fans they are of electronic type with brushless permanent magnet motor with built-in inverter, and in fact ensures high performance by optimizing electricity consumption and reducing noise.

Design
Dimensional
In designing the new range of heat recovery units, they were used exclusively components of absolute aeraulic and electrical quality then making Altair VR and VRX units of the landmarks in the category in terms of efficiency, reliability, accessibility, and reduced noise levels.
All heat recovery units with high efficiency, guarantee returns over 90%.
only type heat exchangers high efficiency, countercurrent, EN308 certificates.
Fans
To obtain a low noise and efficiency, the RER units exclusively use centrifugal fans with reverse blades combined with brushless EC motors with modulating signal 0: 10V. The synchronous electric motors BLDC (Brushless Direct Current) are characterized by a constant rotation speed independent of the load (or torque resistant) but linked to the frequency defined by the inverter. The synchronous brushless motor is "brushless" since current is not sent directly to the rotor but only to the stator, so there is the need to introduce sliding electrical contacts. The onboard microprocessor manages a signal (BEFM Back Electro Carrier Force) feedback that certifies whether or not the synchronous rotation of the rotor with the magnetic field and provide the possible torque corrections so that it is re-established / maintained synchronism and thus the maximum efficiency.
Wall user display
The display makes the unit is completely autonomous, allowing to perform all the operations of common use by the user (ON / OFF, the SET point setting, time programming, air replacement, etc.). It also shows the status of the unit and allows the development of advanced control parameters and configuration used during the starting phase. On display there are the temperature and humidity probes. For a correct reading of the ambient temperature and humidity, it is therefore essential that the display is placed away from drafts and heat sources, or locked in technical compartments.
High efficiency heat recovery
In a dwelling a good ventilation is very important, but when the outside air temperature is significantly different from the internal air temperature, the parts would result in a large amount of scattered energy. The heat exchanger in countercurrent high efficiency maximizes the energy exchange between the air flows in and out, allowing maximum energy recovery. The heat recovery high polystyrene efficiency allows energy recovery exceeding 90%.
ALTAIR VR AERAULIC PERFORMANCE (UNI EN 13141-7)
The unit must be ducted: it authorizes the use only within the represented curve. The declared performances are with CLEAN filters, and guaranteed ONLY with the original filters with low pressure drop.

RECOVERY EFFICIENCY OF HEAT SENSITIVE
Based on the following conditions (UNI EN 13141-7): Tbs fresh air 7 ° C; External 72% RH; Tbs environment 20 ° C; 28% RH environment
Installation
The units are designed for installation in a fixed position, it is equipped with brackets to be fixed prior to the floor or ceiling in a horizontal position, to which attach the unit. Ensured the unit in the right position to connect with the raceway, the connection to the grid and fix the drain pipe on the side inferiore.Le specified dimensions are considered the minimum useful for the correct positioning of the unit and for subsequent maintenance. Allow free access to all the area indicated as shown below.
Maintenance and cleaning filters
Filters can be removed with ease, they can be washed by hand or in the dishwasher.
