HE-RTU
High-efficiency roof top units

The High-Efficiency Roof Top Units from the Roccheggiani HE-RTU range are units designed to guarantee (based on the chosen configuration and accessories) air handling, renewal and purification inside buildings and are particularly beneficial in large production, storage and distribution areas within Industry and the Tertiary sector.

The units in the HE-RTU range are packaged units, designed to be installed outdoors (typically on the roof) and use heat pump technology enabling the units to be extremely compact and efficient.

The units in the HE-RTU range ensure high seasonal energy efficiency also at partial loads, with performances that contribute towards achieving the best energy classification levels in the building where they are installed. Upon request the units can be supplied together with a “Product Compliance Report”, to assist the heating engineer, architectural designer or facility manager, in understanding the contribution provided by the HE-RTU units in terms of certification points for the major world protocols in the field of Green Buildings, such as LEED®, BREEAM®, Home Quality Mark®, Estidama® and HK Beam Plus®.

From a technical point of view, compared to traditional hydronic solutions consisting typically of plants with UTA, chillers and heat generators (which normally use fossil fuels), the use of high-efficiency Roof Top units from the HERTU range can provide better system efficiencies, reduced energy for pumping the various media fluids and lower primary energy consumption, thus facilitating better energy assessments for the plant-building system, based on the various relevant standards.

The Roccheggiani high-efficiency Roof Top units are manufactured in compliance with the UNI EN 12100 standard and the CE marking directives, following an ISO 9001/2000-certified quality assurance system and use R410A Gas as the refrigerant, in line with the applicable legislation.
