As the Kigali Amendment to the Montreal Protocol is implemented domestically, HFCs production quotas are further tightened. Prices of high-GWP fluids such as R134a, R404A and R410A trend upward, while low-GWP alternatives accelerate their substitution.

Read More →Blends such as R404A, R407C and R410A differ fundamentally from single-component refrigerants in charging method. Wrong vapor charging causes composition segregation, capacity loss and even compressor damage.
