Recuperator Prana-200G - supply and exhaust unit. Suitable for domestic use and helps create a pleasant microclimate in a house or apartment. It is unique that when working in the system, exhaust and supply air flows have a parallel flow and do not mix with each other. The device is able to free the room from small particles of dust, pollen and other allergens. And fill it with fresh, slightly warmed air from the street. Although the system does not have filters, this process is possible thanks to a copper heat exchanger. Copper has disinfection properties similar to silver and good heat transfer. This process helps reduce heating costs and keep your home cool in the summer.
