NEW CO2 Refrigerant Reach-In Test Chambers
Platinous J series and AR series are now available with eco-conscious natural refrigerant R-744
ESPEC’s new Platinous J and AR Series reach-in test chambers featuring CO₂ (R 744) refrigerant technology, have been designed specifically for the European market. These innovative chambers combine high-performance testing capabilities with eco-conscious, safe cooling technology, supporting manufacturers across electronics, automotive, aerospace, and industrial sectors in achieving reliable, sustainable testing.
With the new CO2 chambers, ESPEC has integrated CO₂ (R 744) refrigerant, a non-flammable, non-toxic natural refrigerant classified as safety class A1 by ASHRAE, with a global warming potential (GWP) of just 1 and zero ozone depletion potential (ODP). This technology provides manufacturers with compliant, environmentally responsible solutions without compromising on performance.
Key Features of the New CO₂ Chambers:
• Platinous J Series
o PU/PL-3J-C: Lowest temperature –40°C, capacity 408 litres
o PU/PL-4J-C: Coming soon, lowest temperature –40°C, capacity 800 litres
• AR Series
o ARG/ARS-0680-C-W: Lowest temperature –50°C, capacity 680 litres
o ARG/ARS-1100-C-W: Lowest temperature –50°C, capacity 1100 litres
These chambers comply with IEC 60068-2-30 and IEC 60068-2-38 standards for temperature and humidity cycling tests, ensuring your testing meets international quality requirements. Automated control, precise temperature and humidity regulation, and robust design make these chambers ideal for a wide range of R&D and quality assurance applications.
By adopting CO₂ refrigerant technology, the Platinous J and AR Series offer manufacturers the ability to meet environmental regulations, reduce carbon impact, and maintain high standards of product testing — all in one comprehensive solution.
