The multi-purpose Units with R290 natural coolant for 4-tube hydronic systems in Roccheggiani NRE-MPU range are units designed to ensure (based on the chosen configuration and accessories) the efficient and independent contemporary production of fluids suitable for winter heating and summer air conditioning of buildings, maximising heat recovery and ensuring maximum seasonal yield. The Units are designed for all commercial applications, multifamily housing and service industries requiring simultaneous loads for heating and cooling, even with ratios that may differ and vary over time.
The multi-purpose units in the NRE-MPU range enable reduced consumption of primary energy from non-renewable sources with minimum impact on global warming.
Maximum efficiency is achieved through the smart use of heat pump technology, exploiting the request for contemporary loads to ensure heating and cooling demands from the various areas in the building. In high-efficiency buildings, often characterised by opposing, concurrent thermal loads, the multi-purpose units in NRE-MPU range are the most efficient solution compared to conventional systems (e.g. Chillers and Boilers). The distinctive feature which makes the Multi-purpose units by Roccheggiani a truly “long-term green solution” is the use of R290 natural refrigerant. In compliance with the EU F-gas regulations (that have for some time opened the way, in commercial refrigeration, to natural coolants such as R290, NH3 and CO2), this coolant is highly efficient and also future-proof because, with a GWP value of 3 and an ODP of 0, it is already in line with the deadline of 2025 as regards F-gas.
The multi-purpose Units with R290 natural coolant for 4-tube hydronic systems in Roccheggiani NRE-MPU range are manufactured in compliance with the UNI EN 12100 Standard and the CE mark directives, according to an ISO 9001-certified quality assurance system.
