Decentralized heat recovery is a ventilation system that is installed in individual rooms of a building, instead of centrally in one place.It works by recovering heat from exhaust air and redirecting it to the supply air, helping to improve the building's energy efficiency.This type of recuperation allows for individual control of ventilation in individual rooms and minimizes heat losses.It is an increasingly popular option in residential and office buildings due to energy savings and improved indoor air quality.Technical parameters: • Unit air flow rate: 20/30/40/49/70 m3/h• Aluminum heat exchanger • Heat recovery efficiency: up to 89%• Highly effective filters F7/M5• Length 300 - 550 mm, with the possibility of extension by 315 mm (dedicated extension) • Bypass for passive cooling in summer • Unit umożliwia obsługę 1 of the room
