RRU
High efficiency heat recovery unit
- ErP 2018
- Air flows from 1.500 to 15.000 m³/h
- EC fans adjustable with 0… 10V signal
The heat recovery units in the RRU range by Roccheggiani allow all requirements on air quality and energy savings to be met. 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 in the RRU range are equipped with high-efficiency thermal wheels with a very large heat exchange surface in proportion to their volume. This feature enables greater yields compared to other types of heat exchanger, reaching efficiencies of 78%, with the advantage of low pressure drop and extremely modest dimensions for units with considerable air flow rates.
The high level of recovered heat also allows the use of normal heating/cooling systems to be considerably reduced with obvious economic advantages. To cover a vast range of applications, these RRU units are available in 7 sizes, with nominal air flows from 1.500 to 15.000 m³/h and available operating static pressure of 400 Pa.
