DUPLEXVENT FLEXI
The ventilation units of the new original patented DUPLEXVENT FLEXI design range are intended for comfort ventilation with the highest heat recovery efficiency and hot-air heating in all kinds of civil and residential buildings. They are made in four sizes: DUPLEXVENT FLEXI DV1100, DV1600, DV2600 and DV3600. The units are available in multi-purpose design, i.e. for installation on the floor or beneath the ceiling. In addition the unit sides may be interchanged, i.e. supply and exhaust air ports can be used conversely, allowing installation flexibility. The units can optionally by fitted with a hot water heating coil or a chiller (water-based or direct) to be installed directly on the unit. The duct downstream the unit may be equipped with an electric re-heater; an electric pre-heater can also be installed upstream the unit. The DUPLEXVENT FLEXI DV1600 also includes alternative ports that can be interchanged and used on site as side ports. From the construction point of view all units are compact sets containing in a single cabinet two independently powered, highly efficient EC fans with flexibly mounted motors a counterflow high-efficiency heat recovery core with large heat-transfer area, a by-pass damper with an actuator, removable supply and extract air cartridge filters F5 or F7 and a condensate drain pan, all in the same housing. The front door enables easy access to all components. Inlet and outlet ports are round or rectangular based on the unit type. The housing is manufactured with white painted sheet metal panels with polyurethane insulation (U = 0,82 Wm-2K-1). As an option the units can be equipped with a complete control system, including a connection to the internet or to a third party management system – for detailed information see the section on controls.
Features of the DUPLEXVENT FLEXI: • low profile significantly simplifies installations such as ceiling-suspended applications • extreme compactness of new unit types ensures up to 60 % space reduction in comparison with modular units • low purchase cost • multipurpose unit design (floorstanding / ceilingsuspended installations) simplifies ordering and on-site installations • low power input – high EC fan efficiency • high heat recovery efficiency thanks to new generation heat recovery exchangers • low noise • light weight • different types of control systems based on application complexity; fully integrated into the unit • the units meet hygienic requirements in accordance with the VDI 6022 • The units meet stringent efficiency and effectiveness criteria and are certified by the renowned Passive House Institute (Germany).

INSTALLATION CONFIGURATION INSTALLATION POSITIONS AND PORT CONFIGURATIONS
The units are available in multipurpose design, allowing the unit to be installed on the floor or beneath the ceiling. For both the floor and ceiling-suspended installation, the standard support steel legs are used. Chillers must always be suspended separately. Each unit is fitted with several condensate drain pipes as standard. During installation the respective drain should be selected. Chillers have their own condensate drains. The condensate drains used must be connected into a sewer system. During installation the respective drain should be selected. In addition, unit sides can be interchanged, i.e. supply and exhaust air ports can be used conversely. This ensures high installation flexibility on site.
Hot water heating coil HW.2 and /or a water-based or direct chiller (to be fitted directly on to the unit) or an EPO-V electric heating coil (to be installed in to the duct) may be optionally connected to the unit. Note: The chiller may not be fitted to units with spigots in upward position e2. In addition the DUPLEXVENT FLEXI DV1600 unit includes alternative ports (e2 and i2) that can be interchanged on site and used as side ports. For a detailed unit design we recommend a special DUPLEXVENT selection software be used; available at www.airflow.com.

MANIPULATION SPACE MANIPULATION SPACE
When installing DUPLEXVENT units it is necessary to allow for the recommended free space around the unit for manipulation. A minimum space of 150 mm is needed under the unit to install a DN 32 condensate drain pipe. A trap with a minimum height of 150 mm must be installed before connecting the pipe to a building sewer. The recommended space is easily ensured when the standard support steel legs are used. Space in front of the unit is required for opening the door, filter changing and access to all components that require service.
Minimum manipulation space required for the hinged door is marked on respective drawings. For all units 600 mm free manipulation space from an electric control panel, is required in accordance with respective standards.
