EVDEH Dehumidifiers for residential applications.
Description:
The EVDEH is a high-efficiency dehumidifier with an air handling, dehumidification, cooling and heating integration section. Thanks to its internal water coil, the unit can be connected to a heat pump or radiant system to be able to integrate hot and cold air in the room according to the season. The machine 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.
Versions:
Version D: neutral air dehumidification (isothermal).
Unit that dehumidifies the air coming from the recirculation fan only.
The air flow rate is increased by recirculating the room air, thus allowing the cooling circuit to operate, obtaining dehumidified air during summer (compressor on).
The unit is equipped with a post-cooling/heating water coil which, if powered, supplies a cooling/heating integration to the radiant air conditioning system (the connection to the heating/cooling system is optional and does not affect air dehumidification).
Version DC: for dehumidification and integration in cooling/heating mode.
The air flow rate is increased by recirculating the room air, thus allowing the air to be dehumidified and providing 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.
Characteristics:
EVDEH has a compact size, thanks to which it can be easily installed concealed in ceilings and walls.
The structure consists of a self-supporting frame made of galvanised sheet metal with internal insulation, a water coil and a low pressure drop and easily removable filtering section.
Each unit is also equipped with an EC centrifugal fan with low energy consumption, with forward blades for reduced noise. In addition to this, the motors are of the CONSTANT FLOW type, and this allows for self-adaptation to the plant made.
Control electronics
On-board electrical panel with microprocessor and dedicated control, capable of controlling the operation of the unit in terms of temperature and humidity, ventilation, water temperature at the integration coil and refrigerant temperature in the cooling circuit.
The unit features three operating modes:
-SLAVE, the unit is controlled using external controls from the radiant system electronics.
-MASTER the dehumidifier is supplied with the EVCND remote touch panel control (not included, to be purchased separately), which allows the dehumidifier to become an autonomous unit.
-MODBUS the unit is controlled via Modbus RS485 communication.
Models:
EVDEH dehumidification units can be supplied suitable for wall or ceiling installation.
