HRD2 050 - 410
High efficiency Heat Recovery Units
3,68 - 31,4 kW
-
format_align_leftDescriptionThe HRD2 heat recovery units are developed for installation in commercial and service sector such as offices, bars, restaurants, meeting rooms, shops, schools, gyms, and in general in all facilities where the energy cost reduction is of high importance. In modern air-conditioning and air treatment systems, is necessary to create forced ventilation which involves air conditioned expelling, with high energy consumption and high costs. HRD2heat recovery units, using a high efficiency aluminum static heat recovery, can solve this problem by saving more than 70% of the energy that would otherwise be lost with the expelled stale air. These units may be integrated with traditional systems such as fan coils, water coolers or radiators, and can operate both in summer and in winter. The range HRD2 is recommended for suspended ceiling installation and can be ducted to allow the fresh air intake and distribution.
Versions

- OR - Horizontal Installation, right air supply
- VL - Vertical Installation,left air supply
- VR - Vertical installation, right air supply
Features
- High efficiency counterflow heat recovery with aluminium heat exchanger plates, supplementary sealing and built-in motorized by pass device. Aluminium drain pan, fitted with 1/2" condensation outlet (on side for horizontal units and bottom for vertical units). High Efficiency >75% on dry conditions. All sizes are Eurovent Certified
- Plug Fan Direct driven EC motor with Brushless tecnology. Plastic fiber glass reinforced impeller for size 05 to size 10, and aluminium impeller for bigger sizes.
- Self -supporting steel structure, made of 25 mm double pannels with galvanized steel pannel internaly and RAL9002 painted pannel externally. Inspection doors and panels. For horizontal installations longitudinal steel brackets are supplied for ceiling installation, while for vertical installation (floor installation), galvanized steel feet are supplied as standard.
