Highline 270 EC Waterside Fan Coil Unit

Highline 270EC Waterside Fan Coil Unit
Fan Coil Unit
The most popular waterside control
fan coil unit in the UK for the past
15 years, now available with EC
fans having low Specific Fan
Powers. Initially designed to be
fitted into a ceiling void, the
flexibility also allows the unit to be
installed underfloor. Furthermore an
alternative to the standard design is
the Highline 260d, which
incorporates a detachable discharge
plenum and enables a more flexible
discharge arrangement.
Chassis
Units are manufactured from 1.0 -
1.6mm hot dipped galvanised steel and
are constructed without the use of self
tapping screws. All thermal and
acoustic lining is CFC and HCFC
free and class '0' fire rated. All
bearings and moving surfaces will
operate without requiring further
lubrication. All electrical components
and electrical wiring comply with the
current edition of the I.E.E.
regulations. Each unit is factory
tested to ensure that it will continue
to meet its specified performance
with the minimum of maintenance,
throughout its life.
Fans
The fans are of the double inlet, double
width centrifugal type. The scrolls are
manufactured from galvanized mild
steel, complete with forward curved
aluminum or galvanized steel bladed
impellers. All fan and motor
assemblies are statically and
dynamically balanced to prevent the
transmission of vibration to the fan
coil unit casing. Each fan and motor
assembly has thermal
overload protection fitted, via
imbedded thermistors or the
commutation electronics. The motors
comply to BS 5000-11 and BS EN
60034. The motor frame is totally
enclosed and fitted with maintenance
free sealed for life ball bearings.
Motors are insulated to BS 2757
class B (minimum) and tested to BS
EN 61000-3-2 for Harmonic
Distortion and BS EN 61000-3-3
for Flicker.
Heat Exchangers
Coils are manufactured from 0.35 mm
thick solid drawn copper tubes,
mechanically expanded into accurately
pre-formed collars in rippled aluminum
fins. The coils are arranged for
single or multi- circuit operation
via headers. Each coil is fitted with
a manual air vent and drain point.
All coils are factory tested to a
minimum of 35 bar and are suitable for
operating pressures of up to 12 bar
static head. Coils are fitted with 15
mm o/d plain copper tails.
Condensate Drip Tray
The condensate drip tray is manufactured
from hot dipped galvanized steel,
welded at each corner. The tray is then
degreased before anti-condensation
insulation is applied to all internal and
external surfaces. The tray is fitted
with 15 mm o/ d plain brass connection
(22 mm o/d optional). The tray has a
built in gradient to ensure correct
drainage of condensate.
Temperature Controls
Temperature control shall be by
modulation of the control valves
allowing either chilled or heated
water to flow through the
appropriate coil.
Air Filter Options
-Mesh Filter - The filter is
permanent and is manufactured
from a fine woven mesh of
galvanized steel wire, welded to a
rigid galvanized steel frame. It can be
vacuum cleaned in-situ, or
periodically removed for washing
when necessary.
-Media type filter - Filters are
EU3 to Eurovent 4/5 and
manufactured from a synthetic media
secured to a wire metal frame.
Discharge Plenum
The discharge and inlet plenums are
attenuated and thermally lined with a
CFC and HCFC free class '0' fire
retardant non-migratory foam,
which is both vermin and rot proof.
The density of the foam is 11
kg/m3 thereby helping to reduce the
total weight of the fan coil unit.
Electric Heat Element (if required)
The element is manufactured from
stainless steel sheath with spiral
wound stainless steel fins to minimize
surface temperature. It is located
upstream of the fan(s) to evenly
distribute the heat to the final
discharge spigots. Each unit shall
incorporate a manual reset high
temperature cut-out and a Pressure
Differential Switch or Current
Switch, wired to prevent operation
in the event of a fan failure.
