Condensate tray
Under the cooling coil, in the casing floor a tray made of stainless steel sheet has been used to collect
condensate with condensate drains, provided outside the casing. On the tray perimeter, between
the tray and the casing silicone seals are fitted. The tray is fitted with guides, where the cooling coil
is mounted. This enables use of the whole volume, owing to which condensate is drained efficiently
out of the section.
8.3.5.
Droplet eliminator
Droplet eliminator comprises panels made of plastics. Labyrinth-type system to trap the air-entrained
water molecules provides efficient operation even up to 4 m/s. After opening the inspection door it
can be removed freely for maintenance or cleaning.
8.4. SILENCER SECTION
The section has been designed as air-supply and exhaust type in double-deck configuration. The
section comprises: casing, removable splitters.
8.4.1. Casing
Casing construction bases on the spacious frame made of aluminium profile. Wall, roof and
base planes are heat insulation panels made of 45 mm thick mineral. Inside the panel special
reinforcements are used thanks to which the whole structure is stiff and strong. At the service side
there is hinged inspection door closed using clamps with thumb screws. In order to ensure proper
tightness of the whole casing the panels are sealed with special adhesive, and inspection door is
provided with double seals.
To keep tightness between the connected sections, air supply inlets and outlets have insulation on
their circuits. Additionally, in corners of the casing at air supply inlet and outlet sides, steel section
connectors with oblong holes are fitted. When connecting sections, this solution enables to level
freely any slight surface unevenness of setting both vertically, and horizontally.
In order to ensure proper setting of the section on the ground, the casing, in all sizes, is equipped
with load-bearing feet.
8.4.2. Removable splitters
Removable splitters of 100 mm in thickness are fitted. They are made of mineral wool and covered
with thin cloth “veil” type in order to eliminate infiltration of mineral wool parts to the air. Removable
splitters are designed to be fitted horizontally and can be removed by pushing them out down the
guides. This solution enables access to the section for easy cleaning, and connection of the silencer
section to other sections at the inner side of the casing.
8.5. OPTIONAL COMPONENTS
8.5.1. Flexible connector
Designed for connecting the unit to a duct system flexibly so that possible unit vibrations are
not transferred onto ventilation ducts. Comprising strong fabric and mounting frames facilitating
connection to duct flanges.
8.5.2. Air intake cowl
Designed for units in external version. Specially shaped drip with trays on the perimeter protect
the unit inlet against direct penetration of precipitation, e.g. snow or rain. Additionally, inside the
air intake cowl a droplet eliminator is built-in to provide protection of the units against possible
entrainment of rain drops or light snowflakes. Air intake cowl inlet has an inlet grille protecting the
units against, e.g. birds.
