Product Application 

R508B (SUVA 95) is a widely used ultra-low temperature refrigerant. With excellent comprehensive performance, it serves as an efficient and safe substitute for CFC-13, R503 and HFC-23.It is mainly used in cryogenic equipment such as environmental test chambers (thermal shock test machines), freeze dryers, ultra-low temperature freezers, blood bank refrigerators and biochemical test chambers, covering scientific research refrigeration, medical refrigeration and other fields. It is commonly applied to the low-temperature stage of cascade refrigeration systems.

The refrigerating temperature of R508B can reach -80℃ or lower. It is a long-term replacement for R13, R503 and R23 in line with industrial standards, and fully adapts to the operating environment of R503.
