Main components
n
Load bearing structure made of galvanized steel sheet of suitable
thickness, duly insulated with noise-proof/anti-condensing
material, self-extinguishing in class 1. The unit is equipped with 4
anti-vibration isolators.
n
Fan unit with single, dual or triple fan wheel, dual intake centrifugal
type, with statically and dynamically balanced impellers, coupled
directly, equipped with permanently fit condenser and thermal
safety device
n
Switch box located at the side of the hydraulic connections in
order to reduce the service space. Electric connection by means
of screw terminal strip.
n
High efficiency 3, 4 or 6 row heat exchanger, made of copper tube
and aluminium fins secured to the tubes by mechanical
expansion. They are fit with brass manifolds and contain air
valves. The heat exchanger, normally supplied with left-hand
attachments, may be turned 180°.
n
System for collecting and discharging condensate, extending
beyond the hydraulic connections, enabling collection of
condensate from regulating valves eventually. The off-centre
position considerably reduces the required installation space.
n
Air filter made of acrylic material, self-extinguishing in class 1,
with filtering class EU 2. The removable cassette-type filter is
positioned on the air suction inlet and can be pulled out from
below like a drawer.
n
Straight duct connectors on both the air intake and air outlet.
