When you choose a recuperator, you must be aware of

Usually modern homes are very air proof because of heat insulated walls and plastic windows. State-of-the-art building materials are specially created in order to preserve as much heat as possible. Of course, this is ideal for energy saving. However, it is not enough for comfort living, as such airtightness eliminates normal air exchange.
Healthy and normal ventilation happens only when you have both extract and intake of fresh air. Air shafts in our flats cannot fulfill this function as they do not have additional ""assistants"", such as holes in windows, for example. As a result, windows get wet, humidity is increased, fungus emerges and you barely can breathe.

In such conditions you must create forced ventilation in order to provide a healthy microclimate in the premises. Very often it is performed with the help of intake valves on plastic windows. It is a cheap method. Is it effective?

Intake valves have the following principle of operation: specialists make small holes in a window frame of the installed plastic windows, by means of that they decrease the sealing rubber material. Of course, this gives some freshness, though we have cold air in winter and hot air in summer getting into the premises. In fact, it is the same as just to open a window. Moreover, if you ventilate in such a way, you fully destroy the energy saving function of your windows.

There is an alternative. Namely for such situations when it is warm in your household but you cannot breathe, air recuperators have been created not to lose precious warmth.

A recuperator is a heat exchanger which transmits heat from one source to another. It is one of the energy saving innovative methods for ventilation of the premises. Heated up air is removed from the premises and it transmits heat to the cold air outside through the walls of a heat exchanger.

PRANA recuperators have a heat recovery system coefficient which reaches 92%. It means that the air from outside gets into the premises only 9% colder. Whereas intake valves, which are installed into insulated glass units, transmit air of the same temperature as outside. It means that if it is -20°C outside, the air getting inside the premises will be of the same temperature as outside. The benefits of using recuperators are obvious: you receive quality ventilation maintaining warmth.

Apart from that, PRANA decentralized ventilation system has a copper heat exchanger which additionally sanitizes the air.

PRANA Recuperator is an intake-extract countercurrent flow ventilation system (intake and extract happen simultaneously without mixing of air flows). Ventilation system body frame is made of food grade ABC plastic. A highly effective copper heat exchanger is used as an air recuperator.

The system cleans the premises off the air which is polluted with microparticles of dust and smoke; it also provides intake of fresh and clean air from the outside. At the same time intake and extract air goes along different channels and doesn’t mix. During ventilation we have interchannel heat transmission and that actually provides energy effectiveness of the system in any season. A possibility to regulate volume of air which is taken in and extracted provides comfort in premises.

The main task of PRANA recuperator ventilation system development was to reach maximally possible preservation of energetic features of the air. There may be a filter installed in the recuperator frame for the most effective cleaning of the intake air. In PRANA recuperators we use technologies and materials which help maintain natural air features, all their energetic conponents (ion composition, thin energies). These materials sanitize the air and by this preserve its natural freshness. The main component of a healthy microclimate (i.e. preserving warmth in the premises) is gained with utilization of warm air through the effective heat exchanger, heat recuperator.

The system, which was developed consequently, provides fresh sanitized air in the premises with the preservation of energetic component including natural ion composition and thin energies.

When you choose traditional intake ventilation, you must remember that premises chill in winter. It will not happen if you use systems with recuperation. Recuperation, which means return receipt, becomes today more and more popular. Heated air, taken away from premises, transmits heat to cold air from the outside through the walls of the heat exchanger. Due to PRANA recuperators the heat utilization coefficient by the system reaches 91%. The fact that the PRANA system doesn’t contain any filters allows getting fresh air whose energy coefficient is 95-97%. In summer time it will let maintain the comfortable chill of the air conditioner and this is really a double profit. Firstly, you will need less powerful air conditioners, which means cheaper air conditioners. Secondly, you can get significant energy savings while using it (electricity consumption of PRANA recuperators is up to 30 W per hour on average).

The air in the premises is energetically the same as in nature and exactly this creates a healthy microclimate with significantly lower air exchange volume. That in its turn means walls without mould and fungus and dry windows without condensation. There is one more important issue, namely the effectiveness of energy saving. Traditional ventilation consumes up to 30% of money for heating in winter and in summer we spend up to 70% of our budget on conditioning. The usage of a heat recuperator considerably decreases the costs of climatization.

In the era of plastic windows a lot of their owners have a sad experience of emergence of asthma symptoms, allergies and other threatening illnesses which are connected with the organs of breathing. In that context not only people but the houses themselves get sick, mould and fungus appear. It is clear that being in such premises is not only harmful but sometimes is very dangerous for our health. As such illnesses are directly connected with bad quality ventilation, a logical question arises: which ventilation systems and recuperators solve the very essence of the problem and provide us with quality air in all respects. What is the right and effective ventilation?

There is a definite answer for this question: straight flow decentralized ventilation systems with recuperation and they are air recuperators.
