HR HEAT RECOVERY DUCT SYSTEM
The revolutionary HR heat recovery synthetic
duct system is available in Ø 125, Ø 150 and Ø
180 mm. The material insulates and allows
creation of a neat system. The availability of long
sections (2.25 m) makes the HR heat recovery duct
system very quick and easy to assemble with only
a little waste.
Also under complicated assembly conditions,
the flexible material offers practical possibilities.
In addition, the long socket sleeves and
compact bends (15°, 30°, 45° and 90°) take up
less space and make the entire system functional
and practical. The HR heat recovery pipe is used
for the primary fresh air supply from atmosphere
to the unit and the secondary waste air from the
unit to atmosphere.
BRINK AIR EXCELLENT – AIR
DISTRIBUTION SYSTEM
Brink has developed an innovative low profile
range of ducts for the MVHR ventilation market,
complete with all required accessories such as
couplings, end pieces, air seals and restrictors
(dampers). The sophisticated design, dimensions
and layout of the system result in a low air
resistance, which is important for proper
performance of the ventilation system. All ducts
are semi-rigid 100 mm x 50 mm oval.
INSTALLATION EXAMPLE
Every situation requires its own appliance.
For the above installation, the Renovent HR
Medium 2b/2o R was opted for. The ducts from
and to the atmosphere are from our range HR
heat recovery duct system. The ducts to and from
the dwelling are provided with the semi rigid PE
Green Brink Air Excellent ducting. This is all part of
the Brink ‘Climate OK’ program
SOUND REDUCTION
The relatively soft EPE material offers additional
sound absorption compared to more rigid
materials such as metal and EPP. A comparative
measurement of a 90° bend and 3 metres of duct
on a heat recovery unit (at 225 m
3
/h) shows an
additional sound absorption of EPE compared to
metal and EPP of 6 and 5 dB(A) respectively.
