WRG Rondo Plus with 90% heat recovery and up to 51 dB, Dnew acoustic insulation

The extremely compact dimensions of the round form of device provides ther right solution for nearly all wall structures to the new building and especially for Renovation. Here, the modular concept with the variable control system has proven already in the planning as highly flexible. Unlike purely cable systems allows your domestic ventilation at all times to changing user or lifestyle habits by groups (to) definition constantly readapt.

All WRG Plus Rondo Plus devices are designed as a compact supply air and exhaust air 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, moister, pollen and allergens from the outside with fresh air supply.

The used fans 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, has a surface optimized honeycomb structure. The Bionic influenced honeycomb structure allows the optimum ratio between the 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 - Rondo Plus is preferably used in renovation construction. The necessary outside wall duct will be made easily with a core drilling (approximately 200 mm in diameter). In this wall opening the Rough construction ring module Set will be installed.

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

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.

     

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

  • The mounting type V-WRG Rondo 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 Rondo Plus defined zones with central device 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 Rondo 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

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
  • 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

LAW

LAW Mounting straight through the wall

The arrangement of the WRG RONDO IQ is free within the outer wall. Outer wall (through a rough opening of about 200 mm diameter). The adaptation to the different wall assemblies is done via the RS-LAW Plus (Rough construction Ring Module Set), which are designed for defined below wall thicknesses:

  • RS-LAW Plus 300 mm
  • VLE 150 => 80mm; extension module

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

LAL Concealed within the reveal

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

The WRG RONDO IQ sound absorbing ventilator will install with the Rough construction Ring Module Set (RS-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).

LAF3

LAF3 with because of delay down

The air duct of WRG RONDO IQ is freeze proof, vertically guided within the façade cladding down. This ensures problem-free condensate drainage on the external wall cover element e.g. FA-xxx.

The WRG RONDO IQ is sound absorbing ventilators with the rough construction ring module Set (RS-LAL 3) straight out through the wall, and is reduced within the thermal insulation layer to the factory pre-assembled LAF flat duct system.

The weatherproof feature is ensured by the final facade connecting element (with integrated condensate drain).

LAK jamb wall Integrated mounting

The arrangement of the WRG RONDO IQ is free within the jamb wall with horizontal distortion due to the jamb walls. The adaptation to the different wall constructions takes over the LAW Rough construction Ring Module Set (RS-LAW Plus) in special lengths. The weather protection is via a system-compatible stainless steel facade connecting ensured. This installation variant essentially corresponds to the mounting type LAW

LAK1 jamb wall Integrated mounting

The arrangement of the WRG RONDO IQ is free within the jamb wall with horizontal distortion due to the jamb walls. The adaptation to the different wall constructions takes over the LAW Rough construction Ring Module Set (RS-LAW Plus) in special lengths. The weather protection is via a system-compatible stainless steel facade connecting (RS-LAW-K Plus) ensured. Within the jamb wall all ductworks must be insulated!
