Rotary heat exchanger (RX)
Coil heat exchanger (CX)
Plate heat exchanger (PX)
1 GENERAL
1.1 Field of Application
The GOLD units are designed for use in comfort ventilation appli-
cations. Depending on the variant selected, GOLD units can be
utilised in buildings such as office buildings, schools, day nurser-
ies, public buildings, shops, residential buildings, etc.
GOLD units equipped with plate/coil heat exchanger (PX/CX) and
separate GOLD supply air and extract air handling units (SD) can
also be used for the ventilation of moderately humid buildings;
however not where the humidity is continuously high, such as in
indoor swimming baths.
The separate GOLD supply air and extract air handling units (SD)
are designed for applications in which the supply air and extract
air flows need to be completely separated from one another or
where, due to limited available space, separate units for supply
air and extract air are needed. They can also be used individually
if only one of the variants is needed.
In order to fully obtain all the benefits the GOLD system has to
offer, it is important to take the special characteristics of the
air handling units into account when planning them into the
project, installing, adjusting and operating them.
The air handling unit in its basic version should be installed
indoors. The TBTA/TBTB accessory should be used if the air
handling units are installed outdoors. If the duct accessories are
installed outdoors, they must be housed in an insulated casing
(type TCxx).
Important!
Always read the safety precautions in Section 2
about what generally applies concerning risks
involved and who is qualified to carry out the work,
and carefully follow the installation instructions that
are given in each section.
The product identification plates are located on the inspection
side of the air handling unit and on a wall inside the fan section.
Refer to the particulars on the product identification plate when
you contact Swegon.
1.2 Mechanical Design
The GOLD is available in 8 physical sizes and for 14 airflow
ranges.
Its sheet steel exterior is painted in a beige colour. NCS-
2005Y30R. Its door handles and the upper part of the junction
hood are painted light grey. NCS 53502-B. Its interior material
is mainly galvanized sheet steel with 50 mm thick intervening
insulation.
The size 12-30 GOLD units with plate heat exchanger (PX) or
rotary heat exchanger (RX) with air intake from above and the
separate size 04-08 supply air and extract air units (SD) as well as
the GOLD RX Top are equipped with pleated, class F7 filters. The
units in other variants/sizes have class F7 supply air and extract
air filters made of glass fibre.
The type RECOnomic rotary heat exchanger is variable speed
controlled and has a temperature efficiency of up to 85%.
The plate heat exchangers are as standard equipped with by-pass
and shut-off damper for variable and automatic control of the
heat exchanger’s efficiency on heat recovery.
The coil heat exchangers in the one-piece units (CX) are supplied
complete from the factory; including mounted the pipework
package with all the necessary components. The system is nor-
mally filled with liquid, vented, adjusted and performance-tested
prior to delivery, but can be ordered in unfilled condition e.g. for
housing improvement projects or if a liquid mixture other than
30 % ethylene glycol is required. The pipework package is avail-
able loose as an accessory for separate, size 14-80 supply air and
extract air handling units (SD)
The supply air and extract air fans are of GOLD Wing+ type, an
axi-centrifugal fan with backward-curved blades. The fans are
direct-driven and have a motor control system for variable speed
control.
1.3 Control System
The control system is microprocessor-based and is integrated
into the unit. It controls and regulates the fans, heat exchanger,
temperatures, airflows, operating times and a large number of
internal and external functions as well as alarms.
1.4 Environmental Documentation
Environmental documentation with the Dismantling instructions
for recycling and the Environmental Declaration are included as
appendices in these instructions.
The air handling unit is designed for simple to dismantling into
its natural parts. When the unit has reached the end of its useful
product life, engage an approved recycling company for scrap-
ping.
Approximately 94% of the total weight of the GOLD is can be
recycled.

have any questions regarding the dismantling instructions or the
air handling unit’s impact on the environment.
1.5 Type of heat exchanger
The GOLD one-piece air handling units are supplied with either
rotary heat exchanger (RX), plate heat exchanger (PX) or coil heat
exchanger (CX). Coil heat exchangers are optional for the sepa-
rate supply air and extract air handling units (SD).
Sections, functions, etc. that deal with one specific type of heat
exchanger are preceded by an appropriate symbol. The three
symbols used are as follows:
