Key advantages of the PRANA 150 Silent recuperator
Dual-channel system with continuous bidirectional airflow
PRANA 150 Silent operates with two separate channels – one supplies fresh air, the other exhausts used air. This continuous flow without directional change prevents air shocks, maintains optimal humidity, and ensures a constant balance between supply and exhaust.
Copper heat exchanger – natural antiseptic
The heart of the system is the copper heat exchanger, which not only provides exceptional thermal conductivity but also works antibacterial and antimicrobial. Copper naturally destroys microorganisms, keeping the air supplied by the device clean and healthy without additional filters. Read more about the exchanger here.
Extremely quiet operation
With only 8–44 dB(A) operation, PRANA 150 Silent is among the quietest recuperators on the market. The built-in night function further reduces the fan speed, making the device operate virtually silently – ideal for sleeping spaces.
Smart management and automation
You can control it via PRANA Online 2 app, via Wi-Fi or Bluetooth connection, and remote control. A programmable operation schedule is also available, automatically adjusting ventilation according to the hour or season.
Usage and functionalities
Winter mode and automatic defrosting
The Winter Mode function automatically prevents the exchanger from freezing at low temperatures, while the Mini-heating system slightly warms the incoming air for greater comfort.
Free cooling and energy savings
In warmer months, the free cooling mode allows switching to operation without heat recovery, enabling natural cooling of the room and additional energy savings.
Easy installation without modifications
PRANA 150 Silent is installed directly into an external wall – without breaking and additional pipes. The entire installation is completed in about two hours, providing a quick solution without construction work.
