Mechanical Ventilation box with Heat Recovery DucoBox Energy Comfort D400

Description

Mechanical Ventilation box with Heat Recovery (MVHR) DUCO DucoBox Energy Comfort D400

The DucoBox Energy Comfort D400 is an individual mechanical ventilation unit with heat recovery.
Demand-controlled balanced ventilation/heat recovery unit with supply and exhaust fan, equipped with intelligent frost protection, modulating bypass and a high-efficiency plastic cross-flow heat exchanger. The new DucoBox Energy
Comfort D400 combines a high flow rate with high efficiency within a very compact unit thanks to the unique dynamic airflow filters.

The semi-automatic adjustment, by means of unique pressure measurement via the internal sensors, ensures a quick and durable installation of the unit and guarantees a qualitative calibration. Here there is a time saving of 60 % for the
installer and a consequent cost reduction.
By integrating a copy function into the software, it is possible to take over the settings within similar houses in serial construction. This again saves time for the installer.
Since the product is 100% left/right interchangeable, this makes this low-threshold heat recovery unit a very easy product for the installer to order because of only 1 reference. This reduces the margin of error as well as stock
management to an absolute minimum. In addition, all existing Duco sensors and/or user controls are compatible with this new heat recovery unit, due to its modular principle.

Additionally, the unit is future-proof when using the Connectivity Board. This allows interfacing towards home automation and building management systems via REST API (locally or via the cloud) or ModBus TCP (locally). Both are
possible via Ethernet or WiFi. The Connectivity Board also allows the use of the Duco Installation App, which enables the installer to adjust the Duco System (with implementation quality assurance in function of government obligations (e.g. STS in Belgium or Quality Assurance Act in the Netherlands)). For the end user, this means that he can also control his Duco system remotely via his smartphone or tablet.

Operation:
The unit supplies fresh air mechanically to and extracts stale air mechanically from the home with the help of integrated fans. During this process, the heat is recovered from the extracted air and transferred to the air supplied.

Material:
Casing: sheet steel and EPP
Inside: PP, ABS (without thermal bridges) and closed-cell insulation material (EPP)
Integrated heat exchanger: plastic (100 % recyclable; manufactured from recycled material).

Connections: The air ducts for the home connection can be connected at the top of the DucoBox
Energy Comfort D400.
4 Top connections (in EPP):
Outdoor air to the house
Extraction from the house
Exhaust to the outside
Supply from outside
Air connections: 4 x Ø 180 mm female
Exhaust duct from the unit to the outside: Insulated duct
Quantity (pcs.): 1, individually
Outdoor air supply duct to unit: Insulated duct
Quantity (pcs.): 1, individually
Number of zones supply side: The 1-zone system with demand control ensures extremely quiet, intelligent and energy-efficient operation.
Optional, compact and quick to install 2-zone valves provide the most energyefficient result that can be achieved with a heat recovery system.
Frost protection: Equipped as standard with an automatic intelligent energy-efficient frost protection by means of speed control on supply/temporary imbalance and flow
restriction. This ensures frost-free operation of the DucoBox Energy Comfort D400,
guaranteeing proper ventilation during the winter period. Alternatively via an
optional external heater.
Variant: 1 product reference = the product is 100% left / right interchangeable (by the software)

Fans: The direct current EC fans have robust backward-curved blades, making them easy to clean. The fans are vertically mounted and very quiet. The unique positioning of the fan, namely in front of the heat exchanger, ensures optimum noise reduction on the supply side.
Fan type: EC
Type of heat exchanger: The cross-flow heat exchanger is characterised by low resistance, which also contributes to minimal noise and energy consumption. The heat exchanger consists of polystyrene.
Energy class: A+ (in combination with 2 sensors = control factor 0.65)
Air filter/Dust/grease filter: Supply and exhaust sides, standard equipped with dynamic airflow filters coarse 65% (ISO 16890) (class G4).
The filters are easily accessible and removable through a filter drawer mounted at an angle. The filters in the DucoBox Energy Comfort D400 are electrostatic and
anti-bacteriological. They filter the air from pollen and coarse and fine dust. The
filters are selected for a replacement period of 6 months.
(Supply) voltage (V): 230 V, 50 Hz
Electrical connection: Equipped with 2 m cord with earthed/Euro plug
Protection rating: IP 40
Colour: Black with white lid
Surface treatment: Coated (sendzimir galvanised)
Condensate drain: A condensate drain (with pipe diameter 32 mm (1 ¼") externally integrated / threaded) is provided for the drainage of condensation water. This condensate
drain should be connected to the indoor sewer via a water trap (siphon) with a
minimum level difference of 60 mm.
Connection of the condensate drain to the drain line is by means of a siphon with a sufficiently large water trap, e.g. Siphon flat.
Two are provided: depending on which version one chooses (left or right), the
other must be closed.

Features:

Settings: Adaptive / demand-driven, can be expanded with humidity sensor and/or CO2 sensor.
Customised demand control based on sensors that can be linked modularly.
- Time control: Possibility of programming a fixed time schedule.
- Absence mode: In the event of prolonged absence, the absence mode can be
activated so that the ventilation system runs at the most energy-efficient mode.
Control: Direct current constant volume with flow control, always guarantees balanced air flows and flow rates are kept constant.
Automatic calibration: The DucoBox Energy Comfort D400 unit is equipped with a constant volume control. The set air flow rate is automatically controlled independently of duct resistance and filter fouling.

(Summer) bypass: Double automatic 100% modulating bypass as standard.
Can be operated automatically or manually.
The bypass operates fully automatically based on indoor and outdoor temperature measurement. The bypass directs the air around the heat exchanger. In this way, the house is naturally cooled during summer nights.
NightBoost: With DUCO’s standard NightBoost function, the ventilation system is deployed
during summer to support the cooling of warm indoor temperatures. This fully
automatic, smart (night) cooling function temporarily deactivates demand control and causes the system to operate at nominal value. Not only does this reduce the risk of overheating, it also reduces cooling requirements. Smart NightBoost algorithms ensure energy-efficient operation without disturbing night rest.

Filter notification: The unit is equipped with an automatic filter notification, based on the amount of ventilated air. When the filters need to be replaced, the LED on the user control lights up orange when the control is operated. The filter notification can be reset via the RF switch sensor.
