Active ventilation with heat recovery

General Information

Modern construction techniques prioritise energy efficiency, resulting in tightly sealed building envelopes that cannot ensure adequate air exchange through single-window ventilation. Consequently, the risk of moisture damage, mold development, and the build-up of pollutants in indoor air has increased. Hence, numerous regulations, including standards for ventilation systems, now demand both airtight building envelopes and a minimum level of air exchange.
In the Energy Saving Ordinance (EnEv), specific guidelines were established to regulate the essential air circulation, in addition to natural ventilation through open windows. This presents a unique challenge for designers and architects to incorporate efficient controlled ventilation solutions that comply with these requirements. Moreover, the overarching objective is to incorporate heat recovery systems wherever feasible, enhancing energy efficiency.

Ventomaxx offers the optimal solution with its lineup of decentralised ventilation units with heat recovery series WRG RONDO, WRG PLUS and WRG MAKANI R/Q. Our Heat Recovery series is synonymous with top-tier decentralised ventilation comfort, offering exceptional energy-efficient heat recovery and outstanding noise protection. These units go beyond standard individual room ventilation, thanks to a smart control system that opens the door to various cross-room ventilation solutions for controlled air quality in homes, offices, medical centres, schools, kindergartens, and a wide range of residential and commercial spaces.

WRG MAKANI R/Q

NEW IN

Introducing the WRG MAKANI, the cutting-edge evolution of the popular WRG PLUS and RONDO series, equipped with state-of-the-art, high-performance components. It redefines the benchmark for decentralised ventilation solutions with exceptional heat recovery capabilities.

At the heart of the innovative WRG MAKANI series lies a compact fan meticulously designed for decentralised home ventilation, coupled with a robust heat exchanger. This dynamic duo not only delivers impressive airflow performance, reaching up to 62 m³/h (36.5 cfm), but also boasts a solid 85% heat recovery rate, assuring both sustainability and outstanding energy efficiency.

The selection of the appropriate inner wall cover (Z-IQ DESIGN or the Z-PLUS DESIGN) guarantees seamless integration of the WRG MAKANI series into any interior design. With a timeless appeal and the ability to customise airflow direction, it ensures a comfortable indoor environment.

WRG MAKANI  ventilation units can be effortlessly managed through either central or decentral control units. Our customers have the freedom to select the control unit that perfectly aligns with their specific needs, whether it’s about functionality, fan count, or budget considerations.

Central control options are the ZS-PLUS and ZS-TOUCH. Whereas the V-PLUS control unit option offers a decentral solution with built-in control right on the inner wall cover. This convenient feature lets you operate the fans directly from the cover, putting ultimate control at your fingertips.

The V-PLUS emerges as the top choice for control units when it comes to renovation or refurbishment projects as it eliminates the need for laying new cables and offers ventilation system installation without the extra wiring work.

HRV RONDO

The WRG RONDO series boasts a round, highly compact, and modular design that excels as a versatile solution throughout your ventilation concept planning, whether for new construction projects or renovations.

This fan series distinguishes itself with a creative modular ring-module system, consisting of separate, insertable ring sections. We can tailor production to match your precise requirements, and the set’s pull-out feature easily accommodates construction variances. Furthermore, we provide a customized EPP wall module that smoothly integrates into the structure during initial construction phases, eliminating the necessity for subsequent core hole drilling. This not only accelerates the process but also improves sound and thermal insulation. With multiple mounting choices, we guarantee maximum flexibility for your convenience.

Incorporating advanced sound-insulated heat-recovery technology (up to 74 dB Dn,e,w), the WRG RONDO series offers optimal decentralised ventilation comfort. The choice of roomside covers, whether it’s (IQ DESIGN cover or PLUS DESIGN cover) ensures seamless integration of the WRG RONDO into any interior design.

Our fan units can be conveniently controlled either centrally or decentrally. For central control, the Z-WRG RONDO solutions are managed through a central control unit such as ZS-PLUS or ZS-SMART, offering a wide array of program and operating options with an intuitive user interface. This makes it the go-to ventilation system for both new construction and renovation projects.

The V-WRG RONDO version allows you to  control the individual fans directly at the roomside cover. (only PLUS DESIGN cover) and thus more individuality in use. Without any additional cabeling, you can also control several heat recovery devices or device groups at any time via an “internal device bus”. This bus communicates via the existing power grid. The V-WRG system therefore also proves to be particularly advantageous for subsequent installation – without plaster damage.

When using the PLUS DESIGN cover you have the freedom to directly manage individual fans at the roomside cover. This allows for a more personalized and customised ventilation experience of the V-WRG RONDO version without the need for any additional cabeling. What’s more, you can effortlessly control multiple heat recovery devices or device groups through an ‘internal device bus,’ using the existing power grid, eliminating the necessity for extra wiring. This quality makes the V-HRV system an excellent option for retrofit projects, as it doesn’t entail any plaster damage during installation.

WRG PLUS

HRV PLUS

WRG PLUS units represent the premium category in decentralized ventilation systems with heat recovery. Going beyond providing superior ventilation comfort and energy-efficient heat recovery, this unit series offers exceptional noise reduction (47 dB Dn,e,w) in the standard version (LAW) with extremly quiet device operation.

The compact and square design of these units proves to be a strategic advantage when planning an energy-efficient ventilation strategy, especially in the context of new construction projects with angular shell openings.

Every component within this series features telescopic adjustability and have predefined mounting points for easy installation of the roomside cover and facade cover. The assembly process can be adapted to the construction progress at any stage.

The thermally insulated roomside PLUS DESIGN cover includes an adjustable air outlet roller with customisable air flow direction.

Our fan units offer both centralised and decentralised control options. The Z-WRG PLUS solutions are operated through central control units such as ZS-PLUS or ZS-SMART, offering a multitude of program and operating choices with a user-friendly interface, making it the preferred ventilation system for new constructions and renovation projects.

The V-WRG PLUS version empowers you to directly control individual fans at the roomside cover, providing a higher degree of customisation. Without the need for additional wiring. You can manage multiple heat recovery devices or device groups at any time through an ‘internal device bus,’ which communicates via the existing power grid. This feature makes the V-HRV system particularly advantageous for retrofit projects, without causing any plaster damage.
