HE HRU
High efficiency heat recovery unit

The heat recovery units in the HE-HRU range by Roccheggiani meet change of air and energy saving requirements in a wide range of applications. Ecodesign Directive 2009/125/EC requires the control of air quality through the use of forced ventilation for the change of air, causing however greater energy consumption and an increase in costs. The units are equipped with heat recovery units with aluminium plates and high-efficiency cross flows. The exchange surface of the heat recovery device is very large in proportion to its volume. This feature enables greater yields compared to other types of heat exchanger, reaching efficiencies of 85%, with the advantage of a low pressure drop and extremely modest dimensions for units with considerable air flow rates.

The high level of recovered heat allows the use of normal heating/cooling systems to be considerably reduced with obvious economic advantages.

To cover a vast range of applications, these units are available in 5 sizes, with nominal air flows from 1.000 to 8.000 m³/h and available operating static pressure of 300 Pa.

A rapid selection software is available.
