Active ventilation with heat recovery

The SEPHYR series represents a new generation in the field of modern, integrated ventilation solutions for common spaces and offices, nurseries or commercial units, both for new builds and refurbishment projects. Thanks to its innovative design, the SEPHYR can be installed as a centralised or decentralised ventilation solution.

The SEPHYR series can be installed both as a centralised or decentralised system and mounted vertically, horizontally or attached to the ceiling, offering exceptional flexibility and versatility. With its custom design cladding, the decentralised version enhances the aesthetic appeal while ensuring optimal comfort and an unparalleled air performance throughout.

At the heart of the SEPHYR range is an intelligent trio: a highly effective heating coil, an energy-efficient heat exchanger and a powerful fan unit. These three main components are the key to improved indoor air quality with efficient energy utilisation.

Tailored to the specific requirements and installation positions, the SEPHYR series offers up to 144 configuration options as well as a selection of optional components.

The SEPHYR is operated via the supplied ZS-SEPHYR COMFORT control unit. The intuitive and uncomplicated
user interface of the control system enables effortless operation of the ventilation unit in just a few simple steps.

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 D_n,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 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 D_n,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.
