EVHRDS EC Compact unit for controlled mechanical ventilation, dehumidification and air handling systems from 300 to 500 m³/h
-BLDC INVERTER-driven rotary compressor.<br /> -High dehumidifying capacity EVHRDS EC 30 - 65l/day EVHRDS EC 50 – 85l/day.<br /> -Software and algorithm to achieve maximum dehumidifying capacity<br /> -Modulating integration air flow rate and dehumidification. The inverter-driven compressor allows for room comfort to be managed with maximum efficiency.
Description
The unit consists of a one-piece structure including every component for correct operation with wide temperature ranges.
Characteristics
The panels are insulated with 6 mm thick polyethylene.
Dual-suction fans with Brushless EC motor.
Very high efficiency and low noise levels in accordance with Erp regulations.
Coarse filters with low pressure drop easily removable on the recirculation air.
Cooling circuit made of brazed copper complete with: high efficiency compressor, filter drier, finned coils, water exchanger, solenoid valves, throttling device, liquid receiver, high pressure switches.
Command electronics
On-board electrical panel with microprocessor and dedicated control. Fan management, motorised recirculation damper management, timed dirty filter management, recirculation and fresh air management. Possibility of controlling the unit with these three solutions:
1: management via external controls and 0...10vdc signal for air flow rate control from minimum to maximum;
2: management via EVCNU remote panel with built-in T/H sensor;
3: MODBUS RTU RS 485 communication.
Use
Versions DC
Version DC all outside air: unit for the dehumidification of the air coming from the heat recovery unit and for the cooling/heating integration to the radiant air conditioning system.
During summer (compressor on) the unit can operate in 2 modes:
- dehumidification: the unit condenses partially in air and partially in water by means of the plate condenser, obtaining dehumidified air;
-dehumidification + Cooling integration: the unit condenses completely in water, thus obtaining dehumidified and cooled air.
During winter (compressor off), the water coil is supplied with hot water from the heating system and behaves like a fan coil with heat recovery unit.

- EVHRDS EC 50 H K DC
Version DC outside air and recirculation: unit for the dehumidification of the air coming partially from the heat recovery unit and partially from the indoor environment, with cooling/heating integration to the radiant air conditioning system.
