Battling the Coronavirus: new ventilation systems for single-family homes, apartments, schools and medical practices 

Effective protection against infection and fresh air for pleasant room conditions

The image shows the Vitovent 300-W home ventilation system.
The new Vitovent 300-W centralized home ventilation system with an air volume flow rate of 225 m3/h is designed for stand-alone operation in condos and smaller apartments in large residential complexes thanks to its compact dimensions.

Since the outbreak of the global coronavirus pandemic, awareness has grown considerably that good ventilation systems play a decisive role in health and well-being. Fresh, clean and, above all, germ-free ambient air is more important today than ever before. At the same time, it prevents mold growth and protects building structures. During the cold months of the year, heat recovery can also save heating costs and protect the climate. Viessmann creates and maintains living spaces for future generations – with innovative air purification and ventilation systems.

Vitovent 200-P: Innovative ventilation solution for schools

It has long been known that without ventilation systems the air quality in schools and other rooms where people congregate is inadequate. This has negative consequences for health, well-being and learning efficiency. The coronavirus pandemic has sharply increased awareness of this fact. In order to enable essential work in public institutions and, in particular, teaching in schools, Viessmann has developed Vitovent 200-P as an innovative air purification device. The hybrid ventilation unit combines two functions: it purifies the ambient air from aerosols and fine dust while also supplying the room with fresh outside air.

The following contribute to the improvement of room conditions:

  • A HEPA filter filters out fine dust, pollen, bacteria and 99.99 percent of all viruses
  • Low CO2 and VOC concentrations (VOC = volatile organic compounds)
  • Humidity recovery prevents excessively dry indoor air
  • Fresh and clean air evenly distributed in the room

Fresh air – automatically and at the right time

Vitovent 200-P uses what is known as the displacement ventilation principle: by means of a fresh air supply at floor level and the body’s own buoyancy flow, direct and permanent air circulation is guaranteed. Consequently, stale air rises and is then fed into the units, where it is purified and enriched with fresh outside air before being fed back into the room as fresh air at floor level.

The intelligent sensor technology permanently measures the CO2 concentration in the room. The air volume is automatically adjusted based on these measurements. This means it is not necessary to set time programs. The permanent supply of fresh air with heat and moisture recovery ensures a comfortable learning atmosphere and good air quality in an energy-efficient way, even without window ventilation.

TÜV (German technical supervisory association) confirms: Vitovent 200-P fulfills the guidelines of VDI 6022

Following extensive testing by TÜV (German technical supervisory association), it has been confirmed that Vitovent 200-P complies with the structural and design requirements and the hygiene requirements for room ventilation systems as specified in VDI 6022-1.

Smooth operation for undisturbed teaching

Vitovent 200-P is impressive with its very smooth operation and the comfortable room conditions it creates. Since regular ventilation by opening the windows is no longer necessary, the health risk of the indoor air drying out excessively when outside temperatures are very low in winter is also reduced, and both the energy consumption and CO2 emissions of schools are prevented from rising.

Easy to retrofit

The Plug & Play system can be set up within a short period, and as a stand-alone unit it is ideal for retrofitting – for example in classrooms. The units are easy and inexpensive to retrofit by replacing a window pane with an Isopanel. They thus make it possible to keep heavily occupied recreation rooms and public facilities open despite a generally high risk of infection. A 230 V socket is all that is needed to operate the Vitovent 200-P.

Benefits for trade partners

  • Plug & Play allows simple installation – ideal for quick retrofitting

Vitovent 300-W: centralized home ventilation for condos and smaller apartments

The central home ventilation system Vitovent 300-W with an air volume flow of 225 m3/h supplements the proven systems with 325 and 400 m3/h. Thanks to its compact dimensions and particularly quiet operation, it is designed for stand-alone operation in condos and smaller apartments in large residential complexes. The proven combination with a heat pump in smaller single-family homes is also possible.

Control and monitoring via app

With a Vitocal heat pump, convenient control is easy thanks to the ViCare app. And with an online connection, the specialist partner can use Vitoguide to check the proper functioning of the Vitovent 300-W via a web browser.

Save heating costs through heat recovery

With Vitovent 300-W, heat losses that occur with conventional window ventilation are a thing of the past. The central system ventilates with almost no energy loss. It is also extremely energy-saving. During the cold season, the heat exchanger uses up to 92 percent of the energy contained in the extract air to heat the incoming fresh air. The integrated electric pre-heating coil ensures continuous frost-free operation even at low outside temperatures.

Prevents mold, protects the building structure

Through the permanent air exchange, Vitovent 300-W prevents excessively humid ambient air, which is one of the main reasons for mold growth. The humidity in the ambient air always remains in the optimal range. This protects the health of the occupants, as well as the building structure, from permanent damage.

Allergy sufferers can breathe easily

A filter system with an effective optional pollen filter purifies the supply air from allergens and pollutants. The growth and spread of mites and mold is significantly curbed.

Cool ambient air on hot summer days

Operators of the new ventilation system will appreciate the passive cooling function of the Vitovent 300-W on hot summer days. During the warm season, the heat exchanger of the Vitovent 300-W can be completely bypassed via the integrated automatic bypass damper. This temperature-controlled circuit allows cool outside air to enter the rooms at night, ensuring a pleasant freshness.

With an overall height of just 245 millimeters and an air volume flow rate of up to 300 m³/h, the new Vitoair FS central ventilation system is the flattest and most compact unit in its class. Added to this is the particularly quiet operation at maximum output.

System integration with new electronics platform

Vitoair FS is compatible with the new electronics platform and can be seamlessly combined with a Vitocal heat pump. An expansion module to include additional components, such as a photovoltaic system and a electricity storage system Vitocharge VX3 for self-generated electricity, is possible at any time. Then Vitoair FS and Vitocal can be operated independently of the public power grid for large parts of the day.

Convenient remote control via app

With the ViCare app, users can conveniently control their entire energy system at any time according to their specific needs.

High indoor air quality and well-being through enthalpy heat exchanger

The enthalpy heat exchanger in the Vitoair FS recovers not only heat but also humidity from the extract air in winter through its special polymer membrane. It thus ensures that the quality of the ambient air is always comfortable and contributes to a sense of well-being. The water vapor molecules contained in the extract air diffuse through the membrane and are absorbed on the supply air side by the incoming outside air. In this way, excessively dry ambient air can be prevented in winter. In summer, the humidity in the outside air is directly released again, which has a positive effect on comfort. Since the polymer membrane prevents the transmission of viruses, mold and bacteria, Vitoair FS is a perfect hygiene solution for optimal room conditions.

Easy to install and quick to commission

Thanks to universal mounting options, flexible installation is possible, either in a suspended ceiling or on the wall in a utility room. The ventilation ducts can be connected on the right or left.

Quick and convenient commissioning of Vitoair FS is ensured by the ViStart app or the new Vitoguide, which will be available from April 2021.

Click and Go air distribution system: quick, easy and safe to install

Quick, easy and safe – the new Click and Go air distribution system for centralized home ventilation systems makes it particularly easy to install its pipework. The fittings are equipped with an integrated seal – the otherwise time-consuming installation of a seal is no longer necessary. A fixing bracket made of stainless spring steel on the fittings ensures a secure hold of the connection point between the fitting and the duct. Separate small parts – such as gaskets and fastening material – are not necessary and therefore do not get lost or forgotten. Specialist partners thus also benefit from significant time savings.

Visual control for a tight fit

All fittings have a viewing window. The color of the seal clearly contrasts with that of the fitting and the air duct, making a faulty connection easily recognizable. A connection is secure when the seal disappears completely into the fitting and can no longer be seen. In the event of incorrect assembly on the construction site, the connection can simply be loosened and securely reconnected without additional tools.

Available with round and flat ducts

All components follow a uniform, flow-optimized design concept. The new system is also characterized by high step stability. The smooth antistatic inner walls also meet the highest hygiene requirements.

Compared to conventional systems, the new round ducts with 75 or 90 millimeter diameters offer significantly greater flexibility. Narrow bending radii can be realized very easily and with minimal effort.

The flow-optimized free cross-section of the flat duct with dimensions of 140 x 50 millimeters allows more air to be transported. It is suitable for installation in the floor structure, in the wall and in a suspended ceiling.

Markings on the round and flat ducts allow the required length to be determined quickly. Compatibility between round duct and flat duct and with all components in the air distribution network is thereby ensured. Thus, the new Click and Go air distribution system offers a wide range of applications and a high degree of flexibility in new buildings and in modernization projects.

Straightforward – from planning to installation

Planning is the first step before installing the air distribution system. This is just as easy with the new planning tool. The web-based tool can be used from almost any terminal device. Thanks to its intuitive operation, the building setup can be created and the ideal home ventilation system designed with just a few clicks. The automatic compilation and the integrated pressure loss calculation always guarantee reliable planning results. Afterwards, the required material can be transferred directly to the online ordering system.
