CLEANER AND FRESHER AIR

Nowadays we spend most of our time indoors, often at home or at work. All of us are exposed to biological pollutants such as harmful bacteria, viruses, moulds and chemicals.


HRD2 presents an ideal solution to ensure a constant flow of fresh air, to maintain the correct level of oxygen and to remove pollutants. The outside air is filtered and treated by the recovery unit, which integrates with the existing air conditioning or heating system perfectly.

TOTAL CONTROL OF ALL FUNCTIONS

Equipped with an electrical panel pre-installed on the machine and the remote control display provided as standard, the heat recovery does not require any other additional component.


All you need for the heat recovery and air renewal is given within one ready-to-use solution.

CONSTANT AIR FLOW MONITORING

Electronic control of the fan speed guarantees perfect adjustment of the air flow, keeping it constant during the operation and thus maintaining the performance required by the distribution system.


Alternatively, the air flow can be dynamically modulated thanks to the CO2 probe: according to the environmental requirements, HRD2 adjusts the fan speed in order to handle the exact required flow, with great advantages in terms of energy consumption reduction.

BY-PASS SYSTEM WITH MOTORIZED DAMPER

The by-pass system with motorized damper enables the use of the heating or cooling capacity (free cooling or free-heating) contained in the outside air to ensure a further reduction of energy consumption. All of this for free, just by taking advantage of the favorable conditions of the outside temperature.

EC MOTOR - PLUG FANS

The air movement is carried out by centrifugal EC plug fans with free impeller and backward blades.The impeller is made of plastic, reinforced with fiberglass for sizes 050 and 090, and aluminum material for larger sizes. These materials ensure high solidity and resistance that make the impeller ideal for heavy workloads. HRD2 features two brushless type fans, one for the supply air and the other for the exhaust air.

CONSTRUCTION DETAILS

The self-supporting HRD2 structure is characterized by top quality features and details that ensure durability and easy maintenance:

  • Self-supporting steel structure with 25mm double panels made of galvanized sheet metal internally and painted sheet externally;
  • Thermal and acoustic insulation made of non-flammable mineral wool and additional insulation for the parts close to the heat exchanger in order to avoid condensation even with extreme outdoor temperature conditions;
  • Removable inspection openings and panels for easy access to internal components;
  • Supporting feet for vertical versions;
  • Longitudinal mounting brackets for horizontal versions;
  • Compact air filters made of synthetic material (outer layer), fiberglass (inner layer) and a galvanized  
    steel frame. The filters are type F7 with a very low  pressure drop on the external air intake, and type M5  on the ambient air intake. Access to filters is facilitated by removable panels.
