EvoAir R25 Ventilation Unit

EvoAir R25 is a compact and flexible MVHR unit designed for installations where energy-efficient operation, robust construction and great installation freedom are important. The unit is manufactured in Älvsbyn and combines Acetec's many years of experience in ventilation with a well-designed industrial construction. It is built for the Nordic climate and reliable year-round operation.

EvoAir R25 is built with insulated panels, a frame of insulated aluminium profiles and a sturdy base frame. The unit is equipped with energy-efficient EC fans and a stepper-motor-driven rotary heat exchanger for effective heat recovery. Filters with a large filter area provide effective filtration while keeping the pressure drop low. EvoAir R25 is also Eurovent-certified, which means that the stated performance data is verified in accordance with established European standards. Combined with robust components and demand-controlled operation via EvoControl, this keeps operating costs low, year after year.

R series – flexible connections for different installations

The R series design offers great freedom in design and installation through multiple possible duct connections. Each airflow – supply, extract, outdoor and exhaust air – has two possible connection positions, allowing the unit to be adapted to the project.

For example, both extract air spigots can be used at the same time to achieve the required airflow. The supply air is connected to one of the spigots, as the duct heater is installed on a supply air duct. The same unit can be configured with top, side or L-connection. A common arrangement is to connect the exhaust air at the top and the other ducts from the side.

Unused connections are easily covered with the supplied cover caps. This makes it easy to use the same unit in different types of installation and simplifies adaptation during both design and installation.

Choosing the connection variant

Right-hand variant = Supply air on the right (as delivered)
	On delivery, parameter 100 is set to upper, which means the right-hand (upper) fan is the supply air fan. Decide which connections are to be used at the top and side. Cover the remaining connections with the supplied cover caps. Install the duct coil for heating and, if applicable, cooling in the supply air duct and, if required, dampers in the outdoor/exhaust air duct. Cooling coils must be installed in a horizontal duct to allow for the condensate tray. Install the labelled temperature sensors in the respective supply, extract and outdoor air ducts.
Green = Outdoor air Blue = Supply air Yellow = Extract air Brown = Exhaust air
Left-hand variant = Supply air on the left (change parameter 100 to lower)
	Change parameter 100 to lower, which means the left-hand (lower) fan becomes the supply air fan. Decide which connections are to be used at the top and side. Cover the remaining connections with the supplied cover caps. Install the duct coil for heating and, if applicable, cooling in the supply air duct and, if required, dampers in the outdoor/exhaust air duct. Cooling coils must be installed in a horizontal duct to allow for the condensate tray. Install the labelled temperature sensors in the respective supply, extract and outdoor air ducts.

EvoControl Touch

EvoAir R25 is supplied with EvoControl and a separate 4.3-inch touch display as standard – so you get a complete, user-friendly control solution straight away, with no need to buy a display separately.

The system connects to the network via cable for stable communication, and the EvoCloud cloud service is included as standard. With EvoCloud, you can control and monitor the unit remotely from your phone, tablet or computer – adjusting operation as needed, following measurements and history, and quickly checking the current operating status.

With Modbus TCP support, the unit integrates easily into a supervisory control or building management system.
