O.ERRE GHOST-U 160 ACTIVE Local Heat Recovery Ventilator \u2013 60 m\u00b3\/h, Turbo 90 m\u00b3\/h<\/h2>\n

The O.ERRE GHOST-U 160 ACTIVE<\/strong> is a high-performance local heat recovery ventilation unit, or heat recovery ventilator<\/strong>, that ensures controlled air exchange in a room without the need to install a central ventilation duct system.<\/p>\n

The unit is installed through a \u00d8160 mm opening<\/strong> in an exterior wall and uses a high-efficiency ceramic heat exchanger. According to the manufacturer, the heat recovery efficiency reaches up to 93<\/strong>%.<\/p>\n

The GHOST-U 160 ACTIVE is well-suited for single-family homes, apartments, bedrooms, living rooms, offices, and buildings undergoing renovation<\/strong>.<\/p>\n

Airflow up to 90 m\u00b3\/h<\/h3>\n

The GHOST-U 160 ACTIVE has a nominal maximum airflow of 60 m\u00b3\/h<\/strong>, but the Turbo function allows the airflow to be temporarily increased to up to 90 m\u00b3\/h<\/strong>.<\/p>\n

This makes the \u00d8160 model suitable for situations where the airflow from a smaller \u00d8100 local heat recovery unit is insufficient.<\/p>\n

Turbo mode can be used, for example, when there are more people in the room than usual or when more intensive air exchange is temporarily needed.<\/p>\n

Heat recovery up to 93%<\/h3>\n

At the heart of the GHOST-U is a ceramic heat exchanger<\/strong> with a heat recovery efficiency of up to 93<\/strong>%.<\/p>\n

According to the manufacturer, the heat exchanger in the \u00d8160 version is longer than usual\u2014 150 mm compared to 100 mm<\/strong> \u2014which improves average heat recovery efficiency by approximately 5%.<\/p>\n

The purpose of heat recovery is to use the energy from the warm indoor air being extracted to raise the temperature of the fresh outdoor air. This allows the room to be ventilated with less heat loss than simply opening windows.<\/p>\n

Very low power consumption\u2014only 6.5 W<\/h3>\n

Despite a basic airflow of up to 60 m\u00b3\/h, the GHOST-U 160 ACTIVE has a maximum electrical power consumption of just 6.5 W<\/strong>, according to the official technical documentation.<\/p>\n

The device uses an electronically commutated brushless DC motor and ball bearings designed for long-term, energy-efficient operation.<\/p>\n

Quiet Local Heat Recovery Unit<\/a><\/h3>\n

In the GHOST-U 160 design, the motor is located inside the wall behind the heat exchanger<\/strong>. The purpose of this design is to reduce fan noise entering the room.<\/p>\n

According to the manufacturer\u2019s latest official technical data sheet, the GHOST-U 160 ACTIVE has a maximum noise level of 25 dB(A) at a distance of 3 meters<\/strong>.<\/p>\n

This makes the unit an attractive option for bedroom ventilation<\/strong> as well.<\/p>\n

ACTIVE \u2013 Devices Work Together<\/a><\/h3>\n

One of the most important features of the ACTIVE version is the ability to connect multiple GHOST-U devices to each other via a cable to form a Master\/Slave system<\/strong>.<\/p>\n

Up to 16 GHOST-U devices<\/strong> can be connected to a single system. The role of each device is determined by DIP switches.<\/p>\n

This allows you to create a local ventilation system in multiple rooms without traditional central ventilation ductwork.<\/p>\n

For example, you can install units in bedrooms and the living room and have them operate in a coordinated manner.<\/p>\n

4 operating speeds and night mode<\/h3>\n

The GHOST-U 160 ACTIVE offers four fan speed<\/strong> settings, one of which is a special night mode.<\/p>\n

This allows you to reduce airflow when particularly quiet ventilation is desired in the room.<\/p>\n

Integrated humidity sensor<\/h3>\n

The ACTIVE version features built-in humidity and twilight sensors<\/strong>.<\/p>\n

These features allow you to use automatic operating modes and adjust the ventilation according to the conditions in the room.<\/p>\n

A humidity sensor is particularly useful in rooms where humidity levels fluctuate throughout the day.<\/p>\n

Control via Remote Control<\/h3>\n

The GHOST-U ACTIVE system can be controlled using a remote control with a display.<\/p>\n

It\u2019s important to be precise on the Pro Air product page: the latest English-language product information lists the display remote control as an optional accessory sold separately<\/strong>. Therefore, I would not write \u201cremote control included\u201d unless the set you are shipping specifically includes one.<\/p>\n

No condensate drain required<\/h3>\n

One of the practical advantages of the GHOST-U is that, according to the manufacturer, the device does not require a separate condensate drain<\/strong>.<\/p>\n

This simplifies installation, as there is no need to install separate condensate piping to the exterior wall.<\/p>\n

Operates at temperatures as low as \u201330 \u00b0C<\/h3>\n

The operating temperature range for the GHOST-U 160 ACTIVE is:<\/p>\n

\u201330 \u00b0C to +50 \u00b0C.<\/strong><\/h3>\n

This is an important characteristic in Estonia’s climate.<\/p>\n

At the same time, it is important to distinguish between the unit\u2019s operating temperature and its heat recovery efficiency\u2014at very low outdoor temperatures, the actual efficiency of heat recovery may decrease. The Estonian distributor also notes this.<\/p>\n

IPX4 protection rating<\/h3>\n

The GHOST-U 160 ACTIVE has an IPX4<\/strong> protection rating.<\/p>\n

This means protection against water splashes in accordance with the IPX4 rating.<\/p>\n

Washable filters<\/h3>\n

The device uses a double washable dust filter<\/strong> that is easily accessible for maintenance.<\/p>\n

The LED indicator also signals when the filter needs to be cleaned. On the \u00d8160 model, the standard filters can be replaced with compatible filters available as optional accessories.<\/p>\n

Also suitable for recessed installation<\/h3>\n

(with accessory)<\/p>\n

The GHOST-U 160 ACTIVE can be mounted on the wall in the usual way or installed using the separate Built-in Kit<\/strong>, which allows for a more discreet recessed solution.<\/p>\n

The minimum wall thickness for standard wall mounting is 250 mm<\/strong>, and 300 mm<\/strong> for the recessed version.<\/p>\n

The duct included in the standard kit is 500 mm long; a 1000 mm version is available as an accessory.<\/p>\n

I checked these key specifications in O.ERRE’s latest official GHOST-U technical data sheet.<\/p>\n

GHOST-U 160 ACTIVE or GHOST-U 100 ACTIVE?<\/h3>\n

The main difference lies in the airflow and the size of the installation opening.<\/p>\n

GHOST-U 100 ACTIVE:<\/strong> \u00d8100 mm, up to 30 m\u00b3\/h.<\/p>\n

GHOST-U 160 ACTIVE:<\/strong> \u00d8160 mm, up to 60 m\u00b3\/h + Turbo up to 90 m\u00b3\/h.<\/p>\n

Therefore, I would choose the GHOST-U 100<\/strong> for a smaller room or a situation where a \u00d8160 mm duct opening cannot be installed.<\/p>\n

The GHOST-U 160<\/strong> is the better choice if you want greater air exchange, for example, in a bedroom, living room, or office.<\/p>\n

Who is the GHOST-U 160 ACTIVE suitable for?<\/h3>\n

The GHOST-U 160 ACTIVE is a good choice if you want:<\/p>\n

    \n
  • ventilation with local heat recovery;<\/li>\n
  • reduce high CO\u2082 levels;<\/li>\n
