Espec, represented in the UK by Unitemp, has announced the release of a new refrigerant known as R-473A for their environmental test chambers. The gas is an environmentally friendly low GWP refrigerant that has cleared regulations globally, and can be ordered as an option to replace R23 and R-508A. “Its characteristics make it possible to reduce both power consumption and the amount of refrigerant required,” the manufacturer explained.
The new material is designed to achieve high performance in ultra-low temperature cooling applications. Effective to -75°C it has a refrigeration capacity 15% higher than R-23 delivering energy savings and sustained performance. With a GWP of 1830, the gas is 88% lower than R-23 and offers no ozone-depleting potential.
“By combining Espec’s technology with the highly efficient refrigerant, power consumption during product usage can be significantly reduced as well as CO2 emissions lowered,” the company said.
The new refrigerant is currently available on the Bench top temperature & Humidity chambers, constant climate chambers, Platinous J series, environmental stress chambers and walk-in temperature chambers. It will also soon be rolled out across the remaining cabinets.
“Climate change caused by global warming is having a significant impact on earth’s environment and people’s lives,” the company said. “Espec recognises the critical importance of environmental conservation, preservation and improvement and this newest feature demonstrates their commitment to offer the best eco- and user-friendly solution for a long product lifetime.
“Plans are in place to carry out further energy savings in their manufacturing processes and offices and to actively proceed with the introduction of renewable energy. They also intend to carry on development to create further energy savings in their products, to encourage suppliers to set reduction targets and to carry out activities for reducing GHG emissions throughout the supply chain.
“For the moment the new refrigerant is available only for ARS/G -0680-5-E and ARS/G -1100-5-E chambers ordered from May 1st, 2022, on. Other chamber models will follow later, and the company will announce their availability in the near future.
