COMPONENTS WITH THE LATEST TECHNOLOGY
The DV245 Adroit (Integral CO2 Sensor) includes an easily removable, plastic heat exchanger which transfers warmth from the outgoing waste airstream into the incoming fresh air with a thermal efficiency up to 90%, where at no point do the airstreams mix.
The DV245 Adroit (Integral CO2 Sensor) is designed with a unique triple filter facility including a F7 (ISO ePM1 50%) pollen filter which provides additional protection against invisible, harmful particles and creates an ultra hygienic environment, particularly relevant for those suffering from asthma or other respiratory conditions.
Now including an internal carbon dioxide sensor as standard, the DV245 Adroit (Integral CO2 Sensor) units have both relative humidity and carbon dioxide sensors for a demand-controlled ventilation reducing the energy consumption even more by boosting the unit only when necessary. Extracting indoor humidity and carbon dioxide particulates whereas providing fresh air, helps creating a healthy indoor environment for the residents.
All the supply/exhaust air filters (2 x G4/ISO Coarse > 75%, 1 x F7/ISO ePM1 50%) as well as the heat exchanger and fans can be easily maintained via the front access door. To assist this process the maintenance indicator alerts the user for maintenance at a pre-set time interval.
FULLY AUTOMATIC OPERATION
An optional digital controller with LCD display which incorporates four independent environmental profiles, weekly ventilation programming, and full internet control at home or on the go via the Adroit 'Cloud' for separate fan control for easy commissioning and the optional smart frost protection facility which significantly reduces the energy consumed to protect the heat exchanger from freezing during the winter season.
When fitted with an optional electric post-heater, the unit keeps the indoor air temperature at the required level hence saves on heating bills especially during the winter period. It is also equipped with an automatic, 100% bypass facility which fully isolates the heat exchanger at the pre-defined temperature and helps to effectively maintain a temperate indoor air climate during the summer months.
On-demand ventilation can be achieved by using optional external humidity and CO2 sensors which boost the air volume gradually based on the moisture and occupancy levels in the dwelling. It is also possible to integrate the unit into a Building Management System via the MODBUS or the optional KNX converter to monitor and control unit’s functions by a central control system.
EXTRA PROTECTION AND SAFETY
The DV245 Adroit Integral CO2 Sensor) is made of a galvanised steel housing unit which is powder coated both internally and externally to ensure high durability and meet the hygiene requirements. The robust double-skin casing includes 20mm insulation, this avoids any thermal bridging which minimises condensate build-up in the unit and significantly absorbs the fan noise.
Also an auto cut-out switch is fitted which immediately cuts the power off as soon as the front cover is removed providing full safety for the user.
ACCESSORIES:
In addition to a choice of compatible ducting systems a full range of controls, sensors, in-line silencers, floor/wall/ceiling inlet and outlet diffusers are available to complete the installation.
WHAT HAPPENS NEXT?
All centralised mechanical ventilation units require good quality compatible ducting installed to a high standard. To ensure the best results, we recommend the innovative AIRFLEX PRO semi-rigid ducting system to be used with heat recovery ventilation systems.
*Excluding motors. Motor warranty is one year from date of purchase.
CONSULTANT SPECIFICATION
UNIT SPECIFICATON - DV245 ADROIT
The mechanical ventilation with heat recovery unit shall be the DV245 Adroit as manufactured by Airflow, shall be sized as indicated on the drawings and shall be in accordance with the specification.
The unit shall be fully insulated to provide optimum thermal and acoustic performance and shall include a cross counterflow heat exchanger with a 90% thermal efficiency. The heat exchanger shall be protected by a unique triple filter design containing two ISO Coarse>75% (G4) grade filters and one ISO ePM1 (F7) filter on the supply and extract air flow path. The triple filter design shall provide additional protection against harmful particles and shall create ultra-hygienic environment.
The unit shall have low energy consumption EC fans with backward curved impellers design providing a quiet operation and achieving low specific fan power values. The sound power level requirements shall be detailed by the unit's manufacturer and in accordance with the ventilation equipment operation schedule.
The unit shall benefit from a smart frost protection which works in a more energy efficient manner constantly monitoring the heat exchanger conditions and uses the frost heater only when necessary. This significantly reduces the energy consumption and provides more heat recovery throughout the winter season.
As per the Passive House certificate, appropriate measures should be taken to prevent the heat exchanger from getting damaged by frost during extreme winter temperatures (-15C). The heat exchanger frost protection shall be provided by two supply air heaters (total power of 3.0 kW), which comes built-in as standard with the Adroit EPH unit models (Part number: 90001271EPH – DV245(R) Adroit EPH / 90001272EPH – DV245(L) Adroit EPH).
The unit shall be equipped with an automatic, 100% bypass which totally isolates the heat exchanger so that no air passes through it. This prevents overheating the dwelling in the summer season.
The unit shall be supplied with a 3/4 BSP insulated condensation trap. The unit shall be suitable for 250mm (4 ports) duct diameter installed at the top entry.
The unit shall have a dead man's switch preventing the fans from still running, which will enable the filters to be changed and maintained, avoid particulates matter as could cause damage to the heat recovery cell; also for operational safety reasons.
The unit shall be DV245 Adroit as manufactured by Airflow and shall be listed on the SAP Appendix Q Database PCDB. The Adroit DV245 can be right or left handed as per the manufacturer's technical datasheet.
