   Big on energy savings, performance
ENGIE REFRIGERATION HAS announced the availability of its new Pensum Air with a refrigeration capacity of 295 kilowatts.
The German company redesigned its air- cooled Pensum Air series to optimise the range for medium-capacity use, especially under partial loads. The first Pensum Air from the Free Cool Line has been installed at a large research institute.
The eco-friendly chiller uses the future- proof refrigerant R-454B. This has a low GWP value of 466 and, consequently, already meets the future requirements of the F-Gas Regulation which take effect in 2030.
“THE FIRST PENSUM AIR FROM THE FREE COOL LINE HAS BEEN INSTALLED AT A LARGE RESEARCH INSTITUTE.”
For a large German research laboratory working in the field of infectious diseases, this was the key factor in its decision to choose a Pensum Air from the Free Cool line. The cus- tomer was also won over by the low overall weight and the extremely low noise levels made possible by the machine’s installation position on the roof of the building.
ENGIE chillers are already widely used in medical facilities and in the pharmaceuti- cal industry.
   SYDNEY-BASED CONTRACTOR RCS Air recently trialled a new coil coating solution in a bid to reclaim the lost cooling performance of air-cooled HVAC units.
The contractor applied the coating to over 100 coils with impressive results.
RCS Air reported an 80 per cent reduction in heat related breakdowns in summer and savings of between 14 per cent and 20 per cent in energy costs. RCS Air also reported call outs in winter caused by coil ice ups had dropped to zero.
The training provided by Thermal-XR made the application process simple, with 100 per cent positive feedback from clients and the RCS ser- vice team, the contractor said.
The local distributor and technologies direc- tor of Promek, Tony Power, said Thermal XR can extend the life of units by five to 10 years.
He said the coating can reclaim the lost cool- ing performance of air-cooled HVAC units by up to 28 per cent.
“The simple procedure of applying a thin layer of thermally conductive graphene coating to the heat exchanger tube and fins rebuilds the effi- ciencies lost due to environmental corrosion,” Power said.
“Every degraded HVAC&R air cooled condenser
in Australia will improve. The product is aimed at units from five to 40 years old and has shown ex- traordinary results.”
The technology has been developed by Aussie firm, Ozkem, using high tech carbon from the Graphene Manufacturing Group in Brisbane.
Thermal-XR has been also been applied to IGA Brisbane, Downer Group, as well as hotels, banks and health care sites reporting energy savings in the 16 to 28 per cent range.
Power said distributors are now in place across Asia including Hong Kong, Singapore and Vietnam. Middle East trials are also under way with strong interest from the petrochemi- cal industry.
The Thermal-XR coating is rated ASTM B117 10,0000 salt spray hours.
“That rating is equivalent to 12 years in ex- treme marine environments,” Power said. “It will extend client capex by five to 10 years with pay- back in less than two years.
“These are exciting days and we are thrilled to see an Australian HVAC innovation being rolled out across the planet; that hasn’t happened since James Harrison invented the mechanical refrig- eration process.”
The Pensum Air is reliable and eco-friendly.
