2.7.2.
INTEGRAL LPHW POST HEATING COIL
The unit can
optionally be supplied with an
integral
water heater operating with LPHW
to
provide supply air top up heating.
The coils are manufactured with
aluminium fins
,
copper tubes
and assembled on a corrosion
resistant
galvanized casing
.
The maximum operating pressure is 16bar at 110°C.
The heating output is automatically modulated by the
in-built temperature sensors and the integral unit
controls.
Valves and actuators are not included and must be
ordered separately
2.7.3.
INTEGRAL DX (DIRECT EXPANSION)
OR WCO (WATER CHANGEOVER COIL)
Where cooling is also required an
optional
changeover water coil
can be provided operating
with either chilled and/or hot water (depending on the
seasonal requirements) on a common water circuit.
Alternatively a single circuit
reverse cycle
direct
expansion (DX)
coil operating with
R410A
refrigerant
can be offered.
All DX coils are tested to 46bar.
Both DX and WCO coils are manufactured with
aluminium fins with hydrophilic coating
,
copper
tubes
and assembled on a corrosion resistant
galvanized casing
. The cooling coil section is also
equipped with a
plastic droplet eliminator
.
A fully
removable
,
epoxy coated, galvanized
condensate tray
fitted with a 22mm OD drain
connection is provided for condensate collection and
disposal.
The condensate tray is equipped with a
water level
sensor
to
avoid overflow of the tray by stopping
operation.
