EVHRDS EC Compact unit for controlled mechanical ventilation, dehumidification and air handling systems from 300 to 500 m³/h
Description
The EVHRDS EC is a compact INVERTER-driven unit for Controlled Mechanical Ventilation systems with a dehumidification section and cooling and heating integration. The unit is supplied as a plug-and-play solution for quick and easy installation. The unit consists of a one-piece structure including every component for correct operation with wide temperature ranges.
Characteristics
Painted sheet metal self-supporting perimeter structure. 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.
Use
The unit is particularly suitable for residential, commercial or collective residential buildings where dehumidification is required in addition to air exchange due to the presence of radiant systems.
Command electronics
Version K: 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.
Accessories
- V2-1-EVHRD - 2-Way On/Off Water Valve 1/2";
- V3-1-EVHRD - 3-Way On/Off Water Valve 1/2";
- EVFHRDS - Filter Kit (for Recirculation Versions Only);
- EPIV - Insulated Supply Air Plenum.
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.
