Roccheggiani Spa products

The high efficiency Roof Top Inverter units in the NHE-RTU range by Roccheggiani are designed (based on their chosen configuration and accessories) to guarantee the handling, renewal and purification of air inside buildings, especially in small and medium service applications, where an air system is likely to be the best solution for quick installation and commissioning and engineering simplicity. New energy regulations pose a variety of challenges to air conditioning systems used over an annual cycle, that are increasingly based on the use of heat pumps, and may provide opportunities for improved comfort while reducing running costs, thanks to the use of variable speed technologies.

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 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.
