WRG-Plus with 90% heat recovery and highest external acoustic insulation

General information Series WRG Plus

All WRG Plus devices are designed as a compact decentralized mechanical extract ventilation [DMEV] unit with up to 90% heat recovery and optimal acoustic insulation. Ideal for use in „tightly sealed" buildings for the prevention against formation of mold, pollen and allergens from the outside with fresh air supply.

The Installation Preparation by means wall integrated telescopic unit can be already be in the construction phase done. A clean final assembly is ensuring through the prepared threaded fasteners in 20 minutes. The electrical connection is recommended in the new building as a fixed connection (standard) or for the renovation as a network plug connection (optional).

The fans used meet the latest and most energy-efficient state of the art. In all used components, is high quality standard in the foreground, so that a durable operation is guaranteed.

The heat exchanger for intermediate storage of heat from the exhaust air, are equipped with surface features Optimized aligned memory cells in the relationship between surface (= storage area) and free cross section (low pressure drop).

The characteristics of the ceramic material specifically used has a very high specific Caloric storage capability and is equipped with its closed-pore surface easy to clean and thus anti allergen nearly. The outer guide bars center the heat exchanger in the installation set and thus ensure the best possible outflow.

The modular design series of WRG Plus is preferably used in new building construction.

The necessary outer wall feedthrough wall with wall opening (approx. 200 x 200 mm) made easy. In this wall opening will take in the rough telescope set.

  • TE - LAW (straight through the wall)
  • TE - LAL (air supply and exhaust air in the window reveal) installed

The additional duct strip in accordance with the rules of "golden section" in window reveal duct which guarantees an optimal length / width ratio. So unwanted air turbulence are excluded and additional noise sources reduced.

After completion of the finely works the functional unit, Including the design - cover will be mounted. This excludes damages during the construction phase.

Integrated in the room-side design panel control systems differ in the requirements for selected types and thus functions. A humidity sensor is available for all types.

Series V-WRG Plus provides a interface for intuitive device operation. The fan automatically communicate over power lines and do not require additional physical connection to each other.

Units of Series Z-WRG be brought together on a central control units (for up to 6 stations). The centrally located room control ZS-Plus serves as an operating unit.

The Series P-WRG Plus is a type in combination with the Types above and specifically assigned to Premounting. All maintenance work on the WRG Plus series, from filter changing to fan revision are possible without using tools.

The device controller has several program selection functions in five fan speeds (e.g. permanent humidity monitoring, continuous ventilation, push ventilation or cross ventilation). A tamper-proof only memory allows the reading of the actual operating hours since commissioning of the fan and is a possible records procedure in the case of moisture damage as example. May arise between tenant and landlord.

For optimal and concerted equipment control are powerful and flexible systems are available.

  • The mounting type V-WRG Plus serves as a homogeneous interface for intuitive device operation. The fan automatically communicate over power lines and do not require additional physical connection to each other.
  • The mounting type Z-WRG Plus with central control devices (for up to 6 stations) is especially suitable for new construction or for use in more complex renovation works.
  • In combination with the foregoing existing mounting type and especially for pre-installation additional stands the building type P-WRG Plus to choose from.

All systems are designed for easy and quick installation. However, the operation and maintenance of the equipment is possible almost self-explanatory and without tools. For the device controllers stands optionally more program selection functions in five fan speeds available (e.g. permanent humidity monitoring, continuous ventilation, push ventilation or cross ventilation as well night cooling optional, available KNX / EIB).

A tamper-proof only memory allows the reading of the actual operating hours since commissioning of the fan and is a possible verification management in the case of moisture damage as e.g. Between tenant and landlord may occur.The intelligent control system is immediately after connection operational. It coordinates the ventilation equipment room air across and meets all requirements of the requirements for optimal energy savings.

ZS – Plus

The ZS-Plus, is the Room user panel for device series Z - WRG Plus. The control and regulating unit are installed in the device and communicates with other devices regulating units usually group. Preferably, this system is used in new construction or extensive refurbishment case. The communication wires comes together in the central room operating panel.

  • max. 6 devices with only one control unit in one control group
  • up to 4 Program function 
  • low voltage of only 12 V in the device 
  • Comfort control in 5 stages of operation 
  • incl. filter change indicator 
  • various firmware versions 
  • unpaired device operation possible 
  • Operating hours counter standard 
  • Humidity monitoring (optional)

V – WRG Plus

V-stands for variable. The control panel is located in the top cover of the WRG Plus. The communication of the device to each other takes place with the "Powerline" system This saves complex cabling between the devices and therefore preferably that takes place at the subsequent installation or In case of renovation case application.

  • Individual control of each unit 
  • bis zu 4 Programmfunktionen 
  • Single-Mode and Group formation possible 
  • Comfort control in 5 stages of operation 
  • incl. filter change indicator 
  • unpaired device operation possible 
  • Operating hours counter standard 
  • Humidity monitoring (optional)

LAW Mounting straight through the wall

The arrangement of the WRG Plus is free within the outer wall. Outer wall (through a rough opening of about H / W 200x190 mm). The adaptation to the different wall assemblies is done via the TE-LAW Plus (Telescopic unit), which are designed for defined below wall thicknesses / adjustment ranges:

  • TE-LAW Plus 275-460 mm 
  • TE-LAW Plus 460-640 mm 
  • TE-LAW Plus 640-820 mm

The weatherproof function is ensured by a system-compatible stainless steel facade completion (FA-LAW-K Plus) with condensate drainage. In addition to the standard versions, stainless steel natural brushed stainless steel and powder-coated white, other colors are available on request.

LAL Concealed within the reveal

The arrangement of the WRG Plus takes place in wall integrated in the window or door reveal. For floor-length windows arise so ideal possible solutions!

The WRG-Plus sound absorbing ventilator will installed with the telescopic unit (TE-LAL plus left or right of the window) straight through the wall, and is reduced within the insulation layer on the factory a preassembled LAL-flat duct system.

The weatherproof function is ensured by the concealed, final facade connecting element (with integrated condensate drain) including the aluminum facade completion (FA-Plus LAL).
