Heating, air conditioning and ventilation are the most energy consuming systems in a house. Today dictates new principles of design and construction, where energy efficiency, environmental friendliness and energy savings are in the foreground. Therefore, when it comes to choosing the type of ventilation system (centralized or decentralized), more and more people choose the second type.

Usually, centralized (general exchange) ventilation provides air exchange for a number of rooms with one powerful air handling unit. For such system it is necessary to install a network of ducts. Ventilation unit itself has quite large dimensions and often requires a separate room for equipment. Currently, centralized ventilation systems are losing popularity due to the emergence of decentralized (local) ventilation systems.

Decentralized ventilation system with air recovery – a modern ventilation solution for efficient and clearly controlled rooms air exchange. This ventilation system involves installing one or more recuperators, according to the needs of the room. The PRANA decentralized supply and exhaust ventilation system is a compact air handling unit that takes no more than two hours to install. Recuperators weigh from 4.5 to 22 kg (depending on the model), which reduces the load on the supporting structure of the premises. In contrast to centralized ventilations such equipment is suitable for rooms with any height of the ceiling. The main feature of the decentralized ventilation system is the possibility of creating different microclimatic zones in one room – without the construction of walls and partitions.

Where do you need decentralized ventilation?

• Hotels;
• Schools, kindergartens;
• Business centers, offices, co-working spaces;
• Hospitals, clinics, rehabilitation centers, beauty salons, health resorts;
• Hypermarkets, supermarkets, shopping and exhibition halls;
• Fitness centers, swimming pools, gyms;
• Service stations, industrial facilities.

The absence of ducting of the ventilation system is a significant advantage in terms of energy and cost savings. Due to the free air movement, a significant reduction of energy losses and noise is achieved. The recuperator has no operating costs. Decentralized ventilation with heat/cold recovery is the most flexible and user-friendly system. Unlike massive centralized ventilation, this system allows step-by-step modification and renewal of ventilation equipment (if necessary – independent ventilation units repair) without stopping the activity in the room.
