Controlled Mechanical Ventilation (CMV)
Renovated
and energy efficiency,
in every space.
Controlled mechanical ventilation (CMV) continuously renews indoor air, extracting stale air and humidity while introducing fresh, filtered air. In hotels, event spaces, offices, or homes, it ensures a healthy environment where humidity, odours, and stagnant air previously accumulated.
In dual-flow systems, heat from the extracted air is recovered to warm the incoming air, maintaining air quality without wasting the energy already used to condition the space.
Why ventilation
controlled makes the difference
For Always
Renovated
Extracts stale air and humidity, and continuously and automatically introduces new, filtered air.
Heat Recovery Efficiency
In twin-flow systems, heat from the extracted air warms the incoming air, preventing energy wastage.
Less Humidity
e Bolor
By controlling indoor humidity, you prevent condensation, mould, and the damage they cause to spaces.
Comfort
Health and Well-being
Cleaner air improves the well-being of those who live, work, or visit the space.
A range of solutions
adapted to each space.
Effective air renewal, with simpler installation.
The simple flow system extracts stale air from humid zones and allows fresh air to enter through dry zones. It's an effective and more accessible installation solution, suitable for spaces where the priority is to ensure reliable air renewal.
Renovated, simply and effectively.
Renovated, with the most direct solution.
Renewed without losing the energy already spent on climate control.
The dual-flow system extracts indoor air and introduces new air through separate circuits, recovering heat from one to the other. It maintains air quality with minimal energy loss, making it the most efficient and suitable option for air-conditioned spaces such as hotels, offices, or high-performance homes.
Maximum air quality, minimum energy waste.
The air that comes in, heated by the air that goes out.
Zoned ventilation,
no need for conduits.
The decentralised system is made up of units installed directly in each space, eliminating the need for ductwork. It is the recommended solution for renovations or for buildings where the installation of a centralised system would be difficult, maintaining performance with less invasive intervention.
The ideal solution when there's no space for ducting.
Ventilation for every space, with no ductwork required.
What if the air in a space
if it were so cared for
How is your air conditioning?
In hotels and event spaces, where occupancy is high and variable, air renewal is crucial for visitor comfort and often a regulatory requirement.
In offices, good indoor air quality reduces the feeling of stale air and contributes to the well-being and concentration of those who work there every day.
In a dwelling, it prevents moisture and mould, and ensures a healthy environment. In any case, the starting point is the same: assess the space and size the appropriate ventilation system.
Complete comfort
from a space is born
from the right combination.
Combine mechanical ventilation with other Inwatt solutions and ensure a healthy, comfortable, and efficient environment.
VMC + Underfloor Heating
While underfloor heating warms the space from the bottom up, the mechanical ventilation with heat recovery (MVHR) renews the air and eliminates present pollutants. The combined solution allows for the uniformisation of air in the dwelling.
Ventilation, Mechanical Control and Air Conditioning
While the air conditioning regulates the temperature, the MVHR renews the air and controls humidity. Together, they ensure a space with the right temperature and constantly clean air, providing complete comfort for an occupied space.
VMC + Photovoltaic Panels
Mechanical ventilation operates continuously, which represents a permanent consumption. Powered by the energy from the panels, this consumption is largely met by electricity produced in the building itself.

Perguntas frequentes
Uma VMC, ou Ventilação Mecânica Controlada, é um sistema que renova o ar interior de um edifício de forma contínua, controlada e motorizada.
Em termos simples, ela funciona da seguinte forma:
* **Extrai o ar viciado:** A VMC retira o ar sujo e húmido dos ambientes internos, como casas de banho, cozinhas e lavandarias.
* **Introduz ar novo:** Ao mesmo tempo, capta ar fresco do exterior e introduz-o nos espaços de estar, como quartos e salas.
* **Troca de calor (em sistemas de dupla fluxo):** Em sistemas mais avançados (VMC de dupla fluxo), o ar viciado que sai transfere calor para o ar fresco que entra, pré-aquecendo-o no inverno e pré-arrefecendo-o no verão. Isto permite economizar energia em aquecimento ou arrefecimento.
**O que faz uma VMC?**
As principais funções e benefícios de uma VMC são:
1. **Melhora da Qualidade do Ar Interior (QAI):**
* **Reduz a humidade:** Ajuda a combater a condensação e o aparecimento de bolor e maus odores associados à humidade excessiva.
* **Elimina poluentes:** Remove do interior dióxido de carbono (CO2), compostos orgânicos voláteis (COVs), partículas finas, odores e outros contaminantes que se acumulam devido ao uso, à respiração e a atividades domésticas.
* **Melhora o conforto:** Um ambiente com ar renovado é geralmente mais agradável e saudável para os ocupantes.
2. **Economia de Energia (principalmente em VMC de dupla fluxo):**
* Ao recuperar o calor do ar extraído, a VMC de dupla fluxo reduz a necessidade de aquecer o ar frio que entra, diminuindo o consumo de energia para climatização.
3. **Prevenção de Problemas de Saúde:**
* Uma boa QAI contribui para reduzir problemas respiratórios, alergias e outros desconfortos associados à má ventilação.
4. **Proteção do Edifício:**
* A redução da humidade protege as estruturas do edifício contra danos causados por bolor e condensação.
Em resumo, uma VMC é um sistema essencial para garantir um ambiente interior saudável, confortável e energeticamente eficiente, controlando ativamente a renovação do ar dentro de um edifício.
VMC stands for Controlled Mechanical Ventilation. It is a system that continuously and automatically renews indoor air, extracting stale air and humidity and introducing new, filtered air from outside. Unlike simply opening windows, it guarantees constant and controlled renewal, without unnecessary energy loss or the entry of noise and pollution.
What is the difference between single flow and dual flow?
In simple flow, the system extracts stale air and allows fresh air to enter naturally, making it a simpler and more affordable solution. In double flow, air intake and exhaust are done through separate circuits, and the heat from the extracted air is recovered to warm the incoming air. Double flow is more efficient and best suited for air-conditioned spaces, where it prevents the waste of already expended energy.
Is VMC mandatory?
In certain buildings and uses, indoor air quality regulations establish air renewal requirements, particularly in high-occupancy spaces such as commercial establishments, hotels, and services. The conditions vary depending on the type and size of the building. During project monitoring, Inwatt assesses the applicable requirements for each case.
How long should the VMC be on for?
The VMC is designed to operate continuously, ensuring permanent air renewal. Its consumption is low, and in twin-flow systems, this is largely offset by the recovered energy. Turning it off frequently compromises air quality and can encourage the development of damp and condensation.
Does VMC help to combat damp and mould?
Yes, and it's one of its main advantages. By constantly extracting humid air from areas prone to steam and renewing the indoor air, CMV reduces condensation on surfaces and prevents mould, protecting both the health of the occupants and the building itself.
Does the VMC make a lot of noise?
No. Current systems are designed to operate discreetly, with reduced noise levels, suitable for resting and working environments. Good acoustic performance largely depends on a correctly sized and executed installation, with the equipment well-positioned and appropriate ductwork.
Is installation included?
Yes. Inwatt ensures the complete solution: space assessment, sizing, equipment supply, installation by qualified technicians, and subsequent assistance. In the case of Mechanical Ventilation with Heat Recovery (MVHR), the ductwork layout, unit positioning, and airflow balancing are crucial for the system's performance, as important as the quality of the equipment itself.
