KUMA R455A

The new Cibin monoblock range use the latest generation ultra-low GWP refrigerants. With a GWP of only 146, R455A is the definitive solution for future low medium temperature commercial and industrial refrigeration.
After multiple tests and studies based on the entire cold chain, it has been shown that the TEWI (Total equivalent warming impact) of machines operating with R455A is significantly lower thanks both to the refrigerant, COP and the ease of managing the machines, which are more user-friendly compared to old R404A machines.

Safety

The refrigerant used is composed of a mildly flammable azeotropic mixture (A2L in accordance with ISO 817). However, the use of R455A is made safe (in compliance with the principal safety standards) due to the specific flammability properties of the refrigerant, which include:
a) Relatively high lower flammability limit equal to 11,8% (LFL);
b) Relatively low upper flammability limit compared to the low flammability limit 12,9% (UFL);
c) Minimum ignition energy more than 1000 times higher than propane;
d) Flame propagation speed lower than 1,5cm/s.
