The unit is equipped with plug-and - play solution for quick and simplified installation. The unit consists of a monoblock inclusive of each component for the proper operation and allows the operation with wide temperature range.
Characteristics
Perimeter structure self-supporting in galvanized sheet. Panels are made from double sandwich panel, with extrernhally painted finish. The insulation panel is made with high-performance insulation 23 mm thickness. Polypropylene exchanger in countercurrent high efficiency exceeding 90%. Summer and winter operation. Fans plug -fun brushless electronic motor and modulating control. High efficiency and low noise levels. Comply with Directive Erp. ePM1 filter easily removable on external air inlet and outlet on the air. Coarse filters with low pressure drop and easily removable on the air recirculation . Electrical panel on the unit with microprocessor and dedicated control. Refrigeration circuit with high efficiency inverter compressor.
Use
The unit is particularly suitable for residential, commercial or collective residential buildings where, in addition to the air exchange, it is necessary to dehumidify the presence of radiant systems.
Command electronics
Version K: Electrical panel on board unit with microprocessor and dedicated regulation. Fan management, display of internal machine temperature probes, timed dirty filter management, recirculation and renewal air management.
Possibility to control the unit with these three solutions:
- 1: Management through external commands and 0-10vdc signal to control air flow from minimum to maximum;
- 2: Management through remote panel with integrated T / H sensor;
- 3: MODBUS RTU RS 485 communication.

Version
Version DC: version for dehumidification and integration in cooling / heating.
Unit for the renewal of the ambient air with the external one through a high efficiency recuperator, the air flow is increased by partially recirculating the ambient air thus allowing to dehumidify the air and to provide an integration of the cooling / thermal power radiant air conditioning system.
During the summer (active compressor) the unit can work in 2 modes:
Renewal + Dehumidification: The unit condenses partially in air and partially in water through the plate condenser, obtaining dehumidified air;
Renewal + Dehumidification + Cooling integration: The unit completely condenses in water, thus obtaining dehumidified and cooled air. During the winter period (compressor off) the hydronic battery is supplied with hot water from the heating system and behaves like a thermo-ventilator with recuperator.
Operation Only with Ventilation
The EVHRD unit will cater for mechanical ventilation with high efficiency heat recovery. It will be possible to select the fan speeds in order to obtain the desired flow rate to meet the air renewal requirements.
The selectable flow rates are:
On size EVHRD EC 30-15 from 0 to 150 m³/h.
On size EVHRD EC 50-25 from 0 to 250 m³/h.
Ventilation, Dehumidification and Integration Operation
The EVHRD EC unit will continue to satisfy mechanical ventilation with high efficiency heat recovery but will increase the air flow, recirculating from a dedicated room air duct to increase the air volume on the integration part.
The integration part consists of a version
with dehumidification and integration and hydronic integrative batteries.
It finds its most common application in radiant systems where there is a need for dehumidification and the integration of cooling in the summer period. During operation, the unit uses humidity and temperature probes to activate the refrigeration circuit composed of the compressor, the air evaporation coil and the air and water condenser powered by the radiant system, thus realizing the dehumidification of the air and the integration of cooling.
In the winter period, it is however possible to use the unit to integrate the radiant heating by feeding the hydronic hot water battery, obtaining a rapid heat input to the room.
