Welcome Page Active ventilation with Heat Recovery

Active ventilation with heat recovery

General Information

With the aim of reducing the overall energy consumption of buildings and thus both saving heating costs and protecting the environment, buildings have become increasingly dense over the past few years. This means that “natural” ventilation is severely restricted. The adequate supply of fresh air serves on the one hand to improve living comfort and on the other hand to prevent mold and thus to protect the building and the residents. In the Energy Saving Ordinance (EnEv) requirements for the “air exchange” were defined which determine the necessary air circulation, in addition to ventilation by open windows. The challenge for the planners and architects to adhere to these requirements by planning proper controlled ventilation. In addition to a mechanical ventilation, the goal should be to provide some form of heat recovery, where possible.

Decentralized ventilation units from Ventomaxx with heat recovery are available as HRV RONDO, HRV PLUS as well as HRV MAKANI R/Q series. They stand for high-quality, decentralized ventilation comfort with extremely energy-efficient heat recovery and with above-average protection against outside noise. In addition to typical individual room ventilation, the intelligent and sophisticated control system includes numerous combination options for cross-room ventilation concepts for controlled living space ventilation, office ventilation, ventilation for medical centers, schools, kindergartens, etc.

HRV MAKANI R/Q

NEW- as of summer 2023

The HRV MAKANI is the latest iteration of the successful HRV PLUS and RONDO series, featuring updated high-performance components. It sets the standard in decentralized ventilation with heat recovery.

With the high-performance heat exchanger and a fan specially developed for decentralized ventilation, these two components are the heart and lungs of the MAKANI series. Maximum air flow rate of up to 62 m³/h (36,5 cfm) and a heat supply rate of 85 guarantee sustainable construction and a high energy efficiency.

The selection of the appropriate roomside cover(Z-IQ DESIGN cover or the Z-PLUS DESIGN cover) guarantees seemless integration of the HRV MAKANI series into any interior design. Its timeless aesthetic, combined with optimal airflow and customizable adjustment of the airflow direction ensures a superior indoor climate.

HRV MAKANI  ventilation units are controlled via central or decentralised control units. Tailored to the individual requirements in terms of function, number of fans, handling and scope of investment, it can be
selected between the central controllers ZS-PLUS and ZS-TOUCH.
The V-PLUS series with integrated control at the roomside cover allows the fans to be operated directly at the cover. It is the recommendation for refurbishments/renovations, as there is no need to lay cables.

HRV RONDO

The round, very compact and modular design of the HRV RONDO series already proves to be an all-rounder within the planning process of your ventilation concept, both in new buildings and renovations.

The fan series is characterized by the modular ring-module set. It consists of individual inserted ring segments. Production takes place according to your specifications, construction tolerances can easily be compensated due to the pull-out function of the set. A wall module made of EPP and tailored to the system is available, too. It can be integrated directly into the wall during the shell construction phase. This eliminates the need for subsequent core hole drilling and, in addition to time, it also offers extra sound and heat insulation. Different mounting solutions guarantee maximum flexibility.

With sound-insulated heat-recovery (up to 74 dB Dn,e,w) the HRV RONDO series provides highest decentralized ventilation comfort. The selection of the appropriate roomside cover (IQ DESIGN cover or PLUS DESIGN cover) ensures the perfect integration of the HRV RONDO into any interior design.

The fan units are controlled either centrally or dcentrally. The Z-HRV RONDO solutions is operated through a central control unit (ZS-PLUS or ZS-SMART).  Numerous program / operating options and the simple, intuitive operation make this system the most widely used ventilation system in new buildings and renovations.

The V-HRV 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-HRV system therefore also proves to be particularly advantageous for subsequent installation – without plaster damage.

WRG PLUS

HRV PLUS

HRV PLUS units represent the premier class among decentralized ventilation units with heat recovery.  In addition to maximum ventilation comfort and energy-efficient heat recovery, this unit series already offers above-average protection against external noise (47 dB Dn,e,w) in the standard version (LAW) with extremly quiet device operation.

Its very compact, square design already proves to be advantageous when planning your energy-efficient ventilation concept, especially in new buildings (with angular shell openings).

All shell sets of this series are telescpically adjustable and have predefined mounting points for the final assembly of the roomside cover and the facade cover. The assembly of this serie can also be adapted to the construction progress at any time.

The roomside PLUS DESIGN cover is completely thermally insulated and equipped with an adjustable air outlet roller with adjustable air flow routing.

The fan units are controlled either centrally or dcentrally. The Z-HRV PLUS solutions is operated through a central control unit (ZS-PLUS or ZS-SMART).  Numerous program / operating options and the simple, intuitive operation make this system the most widely used ventilation system in new buildings and renovations.

The V-HRV PLUS version allows you to  control the individual fans directly at the roomside 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.
