Application, Operating Conditions and Construction

Manufacturer's Notification

AeroMaster air-handling units are manufactured in accordance
with valid Czech and European regulations and technical standards.
AeroMaster air-handling units must be installed and used only in
accordance with this documentation. The installation and operating
documentation must be available for the operating and servicing
staff, and it is advisable to store this documentation close to the
installed air-handling unit.

Application and Operating Conditions

AeroMaster XP air-handling units are designed for comfortable air-
handling and air-conditioning in an air flow range from 1,500 m
28,000 m 3 /h at air pressure deference of the fan of up to 2,500 Pa.
AeroMaster XP air-handling units are intended for installation on the
floor, and are delivered with a base frame mounted in the factory. They
are designed to transport air without solid, fibrous, sticky, aggressive,
respectively explosive impurities. The transported air must be free
of corrosive chemicals or chemicals aggressive to zinc and steel,
respectively aluminium.
Aeromaster XP air-handling units can be used in normal rooms
(IEC 60364-5-51, resp. ČSN 33 2000-5-51 ed. 3,
ČSN 33 2000-1 ed.2) and in rooms with extended ambient temperature
range ranging from -30 °C to +40 °C without additional measures.
When designing the air-handling assembly, it is necessary to take into
account the temperature and humidity of the inlet and outlet air in
relation to the ambient temperature and humidity. It is especially
necessary to analyze the relation of the unit's casing classification
pursuant to EN 1886 and the risk of condensation, respectively ice
build-up. Degree of protection – IP 44. The unit's accessories (M & C)
are not included – they must be assessed separately. The device can be
used for outdoor installation if equipped with
a protecting roof, the device is water spray proof (rain up to 60° verti-
cal slant) while observing the Installation and Operating Instructions.

Air-Handling unit Construction

The air-handling unit is designed as a modular system. The individual
panels are connected by braces of 50 × 25 mm cross-section. The
panels and braces are interconnected with screw joints - self-tapping
hexagon-head screws 4,2×16 (DIN 7504-K) and plugs.
It is recommended to use a magnetic screwdriver inner hexagon bit,
size 7 (BN 31522, length 75 mm), to assemble and disassemble the
panels.

Panels which are expected to enable occasional service access to the
internal built-in assemblies are provided with grab handles to make
handling easier. Selected sections are, for regular service purposes
(replacement of filter inserts, cleaning of internal assemblies, etc),
provided with inspection doors which are equipped with swivel locks.
All panels are of sandwich construction with a total thickness of
50 mm. They are provided with a quality anti-corrosion surface finish.
The panels are made of steel sheets – galvanized steel sheets (inner
or outer panels), coated steel sheets (outer panels only), or stainless
steel sheets (inner panels only). The thickness of the outer sheet is
1 mm and the thickness of inner sheet is 1 mm or 0.8 mm (galvanized
side panels only).
Galvanized sheet steel material quality: galvanized sheet steel; contin-
uous hot-dip galvanized EN 10 346 Z275 g/m
C2 environment class as per EN ISO 14713. Painted sheet steel material
quality: galvanized sheet steel - continuous hot–dip galvanized EN 10
346 Z275 g/m 2 + 25 m polyester paint, RAL 9002 EN10169 (corrosion
resistance RC3), C2 environment class as per EN ISO 14713.
The panels are insulated with 50 mm thick fireproof mineral wool of
110 kg/m density. The 12x3 self-adhesive sealing, temperature resist-
3
ance from -40 °C to +80 °C and rate of volume absorption below 5%,
is applied on the contact surfaces of panels. The joints are sealed with
a silicone sealant of temperature resistance from -50 °C to +180 °C.
The complete AeroMaster air-handling unit consists of sections. The
section consists of the casing and built-in assemblies. The air-handling
unit sections are assembled in the factory in so-called „transport-
installation" blocks.

Air-Handling Unit Marking

Each section (except the frame) is provided with a type (name) plate
indicating the following data (if applicable):
 Manufacturer's name
 Type, size and marking code of the section
 Order number and year of production
 Weight
 Power supply connecting data (electric distribution system)
 Degree of electric protection

Side Variability of Unit Connections

The design of the AeroMaster unit enables you to combine the sides
of the media supply connections and inspection door location. The
connection side is determined according to the air flow direction (see
figure #1).
