  • Always more in the modern plant design there is the demand to have a Controlled Mechanical Ventilation, which implies the expulsion of con- ditioned air, determining a higher consumption of energy and consequently an increase of prices.
  • The units RPF thanks to the cross-current heat recuperator permit to save more than 90% of energy which otherwise would be lost with expelled stuffy air.
  • RPF could be integrated with traditional systems realized with fan coils, chillers, and could work both in winter and in summer. This series is indicated for both horizontal and vertical installation.
  • The structure is formed by aluminium profiles with thermic cut, connected by nylon angles charged with glassfibre. The sealing panels, of 50 mm thickness, are of the sandwich type in pre-painted plate RAL 9002 (external) and galvanized sheet iron (internal) insulated with polyurethane with density 45 kg/m3. The expandent of the polyu- rethane foam is based on water permitting to reach GWP=0 (Global Warming Potential). The casing is in fire reaction class M1 according to the French regulation NF P 92-512:1986. Removable panels are also foreseen to access to internal components, equipped with safety locks, condensate drain and internal modula- ting rolling shutter of motorized and controlled bypass for free-cooling.
  • Fans of supply and extract of plug-fan-type with synchronous motor with electronic control permanent magnetos (EC). The impellers are oriented in such a way to grant an optimal air flow which goes through the internal com- ponents, with the minimum noise.
  • Air filtration with a filter with G4 efficiency (according to EN779) with low pressure drops on extracted air flow and a compact filter and with efficiency F7 (according to EN779) having a large filtrating surface made of glass microfibre paper, inserted in the intake flow. The two typologies of filters are positioned upstream of the components to be protected, in order to grant low pressure drops, having a large surface available. The filtrating cells are fixed on a proper bearing frame to avoid any by-pass of non-treated air. Their extractability is guaranteed from a proper side opening (standard), superior or inferior (optional) [with reference to the horizontal version].
  • Static high efficiency cross-current heat recovery unit with high efficiency and aluminium plate. The heat recovery unit guarantees the non- contamination of air flows, because the plates are properly sealed.
  • Its performance is not inferior to 90% (EN308) in function to the external conditions: Air of intake: -10°C/90% - Air of extract 20°C/50% and equal capacities between supply and extract. It is included also the function of automatic defrosting made easy by the internal modula- ting rolling shutter and from the possible modulation with intake flow.
  • Regulation Costituted by power electric panel and programmable controller with integrated graphic display. Everything is internally fitted in the unit in an accessible position. The function of regulation are:
    1. Ventilation control (manual control of the standard fans speed);
    2. Thermo-regulation completed with all elec- tric/electronic components (modality of regu- lation in standard extract);
    3. Integrated logics of energy savings: modulating free-cooling / free-heating, anti-freeze, night cooling, air quality control, dynamic set point, speed economy of ventilation , ranges of time;
    4. Complete interfaceability with BMS systems.
