With any system it is always important to have the right product and application to maximise efficiency, with
Flkt Woods new e3co Crown ERU units we have a variety of applications which benefit from our new range.
The applications below give an indication of where the new e3co Crown ERU units can be installed and used to
minimise energy consumption and provide precise air volume control.
Environmental Assessment Schemes
It is now very common for new build projects to try and achieve environmental standards such as those set
out in LEED and BREEAM programs. Flkt Woods, with its market leading knowledge and products in energy
recovery, has helped many projects achieve the very highest levels in both of these schemes.
Energy using Products Directive (EuP)
The various lots within the EuP directive dictates the eco design requirements for minimum efficiency grades and
labelling. Efficiency grades for fans from 125W to 500W are already published, and e3co Crown products are
expected to be included in the near future. The efficiency requirement is the combination of the fan and drive
efficiency, so EC technology will offer the end user or the designer a solution that is better than the minimum
eco design standards.
Energy Performance of Buildings Directive (EPBD)
The Commission of the European Union has recently proposed a revision of the EPBD (Energy Performance
in Buildings Directive, 2002/91/EC). The objective is to further strengthen the effectiveness and impact of the
existing Directive.
The background to this initiative is to optimise energy usage. It was noted that even in member states where the
existing Directive has been successfully implemented, the Commission still identified an untapped potential for
improvements that could further reduce the energy consumption and CO2
emissions from buildings.
Building Regulations - Part L2 for New (A) and Existing Buildings (B)
Effective from October 2010, Building Regulations Part L and F outline the need for a healthier working/indoor
environment, with the target to decrease CO2
emissions by a further 25% from the initial reduction stated
within the 2006 document. The eco design of our e3co Crown range will allow specifiers to create designs
which incorporate the necessary energy usage reductions, whilst still providing precise control of mechanical
ventilation.
European Energy Related Products Directive (ErP)
Not only does the e3co-Crown meet the requirements of the ErP 2009/125/EC, but also EN15232. In addition,
at the heart of the product, its heat exchanger core is Eurovent Certificated.
LEGISLATION
In Europe, all countries now have to design their new buildings to meet energy targets that
are set out in the Energy Performance in Buildings Directive (EPBD). All Flkt Woods Energy
Performance of Buildings Directive solutions are designed to enable full compliance with this
and other directives regarding ventilation and air conditioning.
Being a global manufacturer and supplier makes meeting legislation easier for Flkt Woods. It means that
Flkt Woods must produce solutions at standards that equal the most stringent legislation and guidelines around.
Only by doing this can we ensure that we meet relevant standards within every market.
Applications Legislation
OFFICES
Flkt Woods offer a highperformance product rangecovering all key elements ofthe overall ventilation system.Our products are designedto secure the best overallperformance of the system as a
whole, considering parameterssuch as health and air quality,energy efficiency, noise, firesafety and ease of installation.
EDUCATION
High occupancy levels
during teaching periodsrequire energy-efficient andcontrollable demand-basedmanagement of air quality andtemperature. The comfort,health and alertness ofstaff and pupils is ensuredduring the learning process,but operating costs can beminimised when these facilitiesare unoccupied.
GYMNASIUM/INDOOR SPORTS
Differing types of activityand occupancy mean abroad spectrum of functionalrequirements to ensure efficientremoval of used air and theintroduction of fresh supplies.Systems need to contain and
control the periodic build upof high humidity levels andtemperature.
HEALTHCARE
For a hospital to operate atits maximum potential, it has tohave all systems workingat the optimum. This notonly applies to staff,communications and lifesupport systems, but also
to pipework, cleaning andventilation systems.
RETAIL/SHOPPING AREAS
With high activity levelsduring the working week andweekends, its important tomake sure that all areas ofventilation are maintained and
Flkt Woods has the systemsto achieve all requirements.
RESIDENTIAL
The purpose of ventilation is to
provide clean good quality airby removing the stale, pollutedair from our homes. The maintask is of course to ensure thatthe indoor air is healthy andsafe to breathe. Ventilationtoday is also about energy andsaving energy costs by addingheat recovery to the ventilationsystem.
TOILETS
Fast, efficient removal ofodours and air-borne pollutantscontribute to the maintenance
of cleanliness and anacceptable environment in
communal sanitary areas.
INDUSTRY
Flkt Woods technologyis used widely in industrialprocessing plants and factoriesfor ventilation of work spaces,as vital components in hightech manufacturing facilities,and for maintaining delicateenvironments within high
tolerance levels inpetro-chemical andpharmaceutical plants.

Notes:1) Coil air on temperatures are based on 2 scenarios, where the external air temperature onto the plate heat exchanger is either -5C/90% RH
or 0C/90% RH, which typically result in plate heat exchange air off temperatures of 11C or 15C respectively, which we have then stated aswater coil air on temperatures.
2) Rated kW Powers and coil air off temperatures stated above are max valves, so should not be used to calculate heating loads.

Notes:1) Coil air on temperatures are based on 2 scenarios, where the external air temperature onto the plate heat exchanger is either -5C/90% RH
or 0C/90% RH, which typically result in plate heat exchange air off temperatures of 11C or 15C respectively, which we have then stated aswater coil air on temperatures.
2) Rated kW Powers and coil air off temperatures stated above are max valves, so should not be used to calculate heating loads.
Typical Plate Heat Exchanger Core Performance data
Thermal performance data for the Counter-flow Plate Heat Exchanger core is basedon a nominal Air flow per unit (approx. 80% of maximum) and the foll owing air conditions:
External air temperature: -5C @ 90% RH and Return air temperature: 22C @ 50% RH

Performance curves shown are based on the e3nhanced or e3lite product versions, with an Electric Post Heater fitted (i.e. BE variant).Performance (in terms of pressure) for the e3ssential variant (with no heaters fitted) is approximately 25 Pa higher, while performance(in terms of pressure) for the e3nhanced or e3lite versions, with a Hot Water Post heater fitted (i.e. BC variant) is 45 Pa lower than the BE variant.
Aerodynamic performance has been obtained from tests based upon EN 13053 and conform to ISO 5801.
Max Fan Pressure is optimum for HVAC applications. Data for higher pressures is available on request.
Notes:
1) Coil air on temperatures are based on 2 scenarios, where the external air temperature onto the plate heat exchanger is either -5C/90% RHor 0C/90% RH, which typically result in plate heat exchange air off temperatures of 11C or 15C respectively, which we have then stated aswater coil air on temperatures.
2) Rated kW Powers and coil air off temperatures stated above are max valves, so should not be used to calculate heating loads.
Typical Plate Heat Exchanger Core Performance data
Thermal performance data for the Counter-flow Plate Heat Exchanger core is basedon a nominal Air flow per unit (approx. 80% of maximum) and the foll owing air conditions:External air temperature: -5C @ 90% RH and Return air temperature: 22C @ 50% RH
