Innovative energy efficiency solution. Exhaust air discharge to the condenser section (by means of a specialised air damper) allows a reduction in condensing temperature. Additional condenser - split condenser mode (optional) - Supply air humidity reduction - dehumidification by deep cooling in the evaporator and then heating of the air in the condenser; - For use in regions with high humidity outdoor air, as well as for facilities with requirements to reduce and maintain a set humidity level. Optimal solution for supply and exhaust systems with predominant recirculation In this case, integration of the condenser into the exhaust flow is not feasible. Low noise level - Compressors inside a noise-insulated enclosure; - Quiet and energy-efficient EBM PAPST HyBlade axial fans. Versatility of application
