Swegon’s GOLD units are designed for comfort ventilation. To ensure superior performance, we design our own components, such as our rotary heat exchanger, fan impeller and control equipment. Commercial or retail construction? Public premises or residential properties? Whatever your segment, there’s always a model to serve you best. Our unrivalled expertise and support are naturally included, right from your planning phase and commissioning through to the first actual use of the unit in future.

GOLD Unit with Composite Hinges and Flush Mount Handles
The door arrangement on GOLD units is set up for maximum accessibility even in tight spaces. Access to all internal components is achieved from one side so placements against a wall or in a corner are no problem. The F version door handles are flush-mounted for safety will offering a two-step opening process. The first step holds the door slightly open allowing any pressure to be relieved and the second step allows the door to swing past 90 degrees for service accessibility.
The composite hinges greatly reduce thermal bridging. Thermal bridging leads to heat loss and gain through the cabinet lowering performance and increasing operating cost.
The performance goals of any air handling unit cabinet are to have the lowest air leakage rate and heat/loss/gain possible. Low leakage saves fan energy while improved thermal performance improves heating and cooling costs. The advanced cabinet design used in GOLD is tested to Eurovent EN 1886 – Ventilation for Buildings – Air Handling Units – Mechanical performance.
The GOLD unit has the highest ratings for cabinet and filter rack air leakage while still delivering excellent thermal performance and low noise.
Filter leakage: F9
Thermal bridges: TB2.
Thermal transmission: T2.
Mechanical strength: D1. F
GOLD Outdoor Unit
Not all projects have space indoors for mechanical equipment. That is why the GOLD units can be placed both indoors and outdoors. The top panel of the GOLD unit overhangs the doors and along with improved door handles the GOLD unit can be used rain or shine.
GOLD Roof Panel With Integral Rain Gutter
The enhanced roof design has triple broken roof panels for weather sealing and an integral rain gutter to redirect rain away from the door area.
A smart system also has to be easy for the user. The IQlogic control system with its award-winning user interface and convenient IQnavigator hand-held terminal makes it easy for you to unlock the full potential of GOLD. Naturally, GOLD is readied for online connection and communication with the main control system. Thanks to our built-in WiFi, you can connect with the unit’s control functions via your smartphone or other mobile devices.
The IQLogic controller contains more than 60 control algorithms to configure it to meet the needs of your project. For more information on the available control sequences, click here.
This feature allows you to test the control system in the GOLD unit from your internet browser.

The fans in an energy recovery ventilation unit will use more energy annually that anything else. That is why at Swegon we developed our own fans which are quiet and energy-efficient. The fans are direct drive, mixed flow plenum type. Direct drive avoids the energy loss, maintenance and reliability issues associated with belt-driven fans.
Swegon fan performance is based on the fans in the cabinets so what you see is what you get without any additional system effect corrections required.
The plenum fans have a high number of blades that shift the sound into the higher frequencies making it easier to attenuate. In most applications, GOLD units do not need any additional sound attenuation. The whole fan/motor assembly is mounted on special rubber in shear (RIS) vibration isolators with flexible bulkhead connectors specifically designed to stop any high-frequency vibration from entering the building. No other isolation is required.
The motors are EC (permanent magnet synchronous motor) type that deliver the highest efficiency over the full speed range of the fan. The motors are serviceable TEAO (totally enclosed, air over) providing long life.
The EC motors are matched to Swegon designed motor controller that can vary the airflow so all GOLD units can be either constant volume or variable airflow. The motor controller is linked with the GOLD IQLogic controller via Modbus for fully integrated control.
All GOLD fans include a piezo ring airflow monitor connected to the GOLD units IQLogic controller so you know the airflow all the time. You can control the airflow by simply inputting the required airflow rate and the GOLD unit will deliver the airflow regardless of air density, filter loading or external static pressure.
Fan servicing is quick and easy. Just disconnect the control and power wiring harnesses, loosen the turnbuckles and flex duct connector and remove the fan assembly. Install the new fan assembly and you are up and running in minutes.
Keeping the ventilation air clean is critical to achieve good IAQ. While ASHRAE standard 62.1 only requires MERV 8 filters, GOLD units come standard with MERV 13 filters in the supply and exhaust airstreams for added protection.
The special filter rack in GOLD units pulls the filters forward and seals the filters to the filter frame to ensure the air flows through the filters and not around them. The leakage rate is less than 0.5% of nominal airflow, giving GOLD a Filter leakage classification of F9, the highest for Eurovent Standard EN1886.
GOLD units have integrated filter pressure drop transducers that monitor the filter life and let you know when the filters require changing.
GOLD units also include a 2 inch (50 mm) prefilter rack that can hold MERV 8 prefilters. This filter rack also has integrated pressure drop transducers so prefilter life can be monitored separately from main filter life.
Other filter options are also available including carbon filters and hoare frost filter arrangements.
Units with rotary heat exchangers allow you to achieve the ultimate in temperature and annual energy efficiency; our patented heat exchangers with turbulent air flow are uniquely effective. This, combined with the short installation length typically makes them the first choice for most applications. The turbulent flow in the rotor and the Carry-Over Control feature makes them ideally compatible with VAV and DCV system applications. The rotors can be surface-treated in different ways. For example, with the RECOsorptic sorption technology coating for enhanced humidity recovery, or epoxy for heavy-duty environments. GOLD RX is designed to minimise the risk of air and odour transmission between the air flows.
A counter-flow heat exchanger is an excellent choice for applications in which you want to separate the air flows. GOLD PX is available in two versions depending on whether your priority is superior temperature efficiency or low pressure drop.
The RECOflow heat exchanger has a high air-seal class, which minimises internal leakage. This makes the GOLD PX an excellent choice for residential properties. Cold weather and humid extract air pose a risk of frost formation in the heat exchanger. To prevent this, our GOLD PX integrates RECOfrost – the best anti-freeze protection on the market. This unique feature uses the latest data from the unit to provide adaptive and demand-controlled adjustment for optimised energy recovery. RECOfrost adjusts the pressure drop across the heat exchanger in periods when full recovery is not needed, e.g. in spring and autumn. The result is superlative temperature efficiency and energy balance, in any climate.
The GOLD SD is a complete air handling unit with separate supply and exhaust air components, supply air and exhaust air fans as well as supply air and exhaust air filters as optional extras. The unit components can also be used as stand-alone supply air fans, exhaust air fans and for single direction air flow. SD units in the supply and exhaust air streams can be connected with a run around loop for energy recovery. A run around loop overs 100% air separation and can connect the supply and exhaust air streams in different parts of the building.
Seamless integration into your Building Automatic System with GOLD IQLogic controls is easy. GOLD IQLogic supports BACnet IP, Lonworks, Metasys and Modbus.
GOLD NA units are UL 1995 and 1812 certified.
Swegon GOLD RX (sizes 04-35 and 50) is certified by the Passive House Institute for its high energy efficiency and heat recovery. GOLD is unique in being the only certified ventilation unit for high air flows (<5,400 cfm).
