New addition to rooftop portolio
TRANE HAS INTRODUCED the new Airfinity S rooftop air-to-air heat pump units with low global warming potential (GWP) R-454B refrig- erant and Adaptive Frequency Drive variable speed compressors.
The new addition to the Trane Airfinity roof- top portfolio is the Airfinity S air-sourced roof- top heat pumps with R-454B, variable speed technology and intelligent control.
Available in capacities between 16 and 39kW
The new Airfinity S rooftop unit.
in cooling and 14-36kW in heating, the new units offer proven performance with lower envi- ronmental footprint and a business-sound and sustainable alternative for fossil-fuelled heating systems in small to medium commercial and process applications.
The Airfinity rooftops are designed for flex- ibility and can be easily adapted to any roof curbs, eliminating complicated retrofit proce- dures. Being a plug-and-play, all-in-one
cooling, heating and ventilation solution, the units save installers’ time and reduce first and ongoing maintenance and ownership costs.
The Trane Adaptive Frequency Drive technol- ogy delivers improved part load efficiency and adapts seamlessly to the building’s demand reducing energy consumption and offering tighter temperature control.
“THE ADAPTIVE FREQUENCY DRIVE TECHNOLOGY DELIVERS IMPROVED PART-LOAD EFFICIENCY.”
To further increase sustainability of the buildings’ operations, Trane Airfinity S rooftops come with additional energy-saving features like adaptive airflow with variable speed fans, free cooling and heat recovery of exhaust air.
The low GWP R-454B refrigerant, offered by Trane across its entire portfolio of scroll compressor chillers, heat pumps, multi-pipe units and rooftops is a non-ozone depleting HFO/HFC blend with GWP level of 467. The GWP is the lowest among the refrigerants available today for scroll compressor technology.
R-454B offers 76 per cent reduction in direct GWP impact against R-410A and 34 per cent reduction against R-32 refrigerant.
Global coalition of first movers
ALFA LAVAL IS now part of the First Movers Coalition (FMC), a global initiative launched by the World Economic Forum.
It is a coalition of companies joining purchas- ing power to support the decarbonisation of seven sectors of industry and long-distance transport that produce hard-to-abate CO2 emissions.
Alfa Laval’s membership is a part of the com- pany’s commitment to becoming carbon neu- tral by 2030.
The First Movers Coalition (FMC) was launched in 2021 by US president Joe Biden.
Alfa Laval will work together with more than 70 other member companies to address road- blocks to securing the supply of required low- carbon technologies by 2030.
The coalition addresses several areas: alu- minium, aviation, chemicals, concrete,
shipping, steel, and trucking, along with innova- tive carbon removal technologies. These sectors account for 30 per cent of global emissions.
Alfa Laval’s work with the FMC is connected to steel and the company’s commitment to be carbon neutral by 2030. By reducing its own CO2 emissions in Scope 3 (related to the steel the company is using in its products) and through- out the value chain, Alfa Laval contributes to meeting the 1.5-degree target defined in the Paris Agreement.
The coalition’s members commit in advance to purchasing a proportion of the industrial materi- als and long-distance transportation they need from suppliers using near-zero or zero-carbon solutions, despite the premium cost.
Alfa Laval has been established in Australia since 1926. ✺
