HEAT RECOVERY UNIT ( HRU )

What are Heat Recovery Units? A Heat Recovery Unit is designed to capture energy from the exhaust air that exits a building and repurpose it to precondition the incoming fresh air. This method not only saves energy but also lightens the burden on the building’s heating and cooling systems.

Usage  HRU units are commonly employed in building ventilation systems to recover waste heat from exhaust air. By doing so, they reduce the need for extra heating or cooling, leading to lower energy costs and a smaller carbon footprint.

• Cold climate operation: HRUs preheat incoming cold air using heat from exhaust air.
• Warm climate operation: HRUs precool incoming hot air using cooler exhaust air.

Construction  HRU units are commonly designed in two types are as follow :

• Plate Heat Exchanger Recovery Unit
• Rotary Heat Exchanger Recovery Unit
