The year 2013 is the beginning of a new era for Airvent. Based on our extensive, 18 years of experience and knowledge gathered in the manufacturing and distribution of air handling units, we set out to develop a brand new line of units under the new name, Plex. The main target in the development process was to use a wide range of creative engineering solutions, while preserving the excellent quality and reliable characteristic that Airvent products are known for. As always the main focus of our design team was to create a product line that includes a variety of solutions that are valuable to our customers. One of our innovations we are really proud of is EasyLink. This is a new and patented assembly system, for a simple and elegant way of connecting or disconnecting the sections of the air handling units, without having to enter the modules. This is one of many solutions we believe our customers will appreciate, due to the really short installation time on site. We have also partnered with the most reliable fan and heat recovery suppliers in the world to be sure that Plex is in compliance with present and future energy-saving regulations and quality requirements. We provide all our standard air handling units with silent fans equipped with speed controlled EC motors.
Please contact our sales engineers to receive the best support when choosing the unit type and size that suits your needs the most.

EasyLink is a brand new, revolutionary and patented assembly system specially designed for Plex. As the name implies it is a simple, elegant and accurate method of connecting or disconnecting the air handling modules from outside with a regular screwdriver tool in just a few minutes. EasyLink steers the modules to the correct position, is extremely solid and prevents leakage.

The inspection doors of our air handling units are as standard equipped with Dual, a flexible handle-hinge device. Dual enables the inspection doors to be opened both to the left and to the right side, or if the space is limited on site, the door can easily be removed. This makes the maintenance and cleaning of the units a lot easier for the operator.

The rotary heat exchangers applied in Plex air handling units are Eurovent certified and operate with a very high heat and cooling energy recovery efficiency. Besides the high energy efficiency a great advantage of rotary heat exchangers is the short installation length, for smaller machine rooms. The rotors used for Plex units have as standard variable speed regulation and operation control functions, plus a purging sector to prevent the leakage of exhaust air into the supply air. Hygroscopic surface is an option.

Plate heat recovery
The cross-flow plate heat recovery units applied in Plex air handling units are Eurovent certified. The flat air passages in the airflow direction results in a low pressure drop and low risk of dust or dirt deposits in the passages. The special jointing technology ensures that the unit is tight and it minimizes the risk of leakage between the extract air and supply air paths. Plate heat recovery exchangers are produced with bypass and drip trays as standard. Epoxy coated surface is an option.

FanAs standard, Plex units are produced with plug fans equipped with EC motors (which even meets the strict requirements due to be introduced from 2015 in the EU), and integrated variable speed control. The support brackets for the fans are specially designed for Plex units; upon request tandem arrangement of the fans is also possible. To facilitate the maintenance, the fans are produced in a slide-out or in an easily removable design.
The regulation of Plex air handling units are performed with an integrated automatic control system. To save heating and cooling energy, the temperature can be regulated with heat recovery control. The air volume is measured on the supply and extract air sides and it is easy to set. The Plex control unit can manage the control of external units (cooling units, pumps, etc.) as well. The control system can be connected to Modbus or LON building management systems and can be ordered optionally with a hand-held or wall-mounted LCD display control terminal. Besides the local remote control, the web interface also enables to record operation data and to obtain statistics. The automatic control is the executive component of ControlAir System Management developed by Airvent, which leads to significant energy saving.

Our well-known, high quality sound attenuators are produced either with fixed, or for an easy cleaning with pull-out baffles. The attenuators are designed with regards to the noise level of the source and the required level of noise reduction. The attenuators built in the air handling unit’s casing are available from 500 to 1500 millimeters length.
The heating- and cooling coils applied in Plex units are produced in a conventional design of aluminum fins pressed on copper tubes. Each coil is selected according to the required parameters and optimized for its working point. The special plastic profile of the droplet eliminator’s lamellas is made of environment-friendly recycled material. Electric heaters are made of stainless steel tubular heating elements for high surface temperature. They are provided with double thermal protection and integrated control equipment.

Plex air handling units with heat recovery are produced in two types of cross-section design: in square or rectangular versions. These designs ensure the application of heat exchangers with the lowest internal pressure drop, the most advantageous settlement of fans, and the easier placing of air handling units in engine rooms with standard height.
