Petra Accomplishes the Environmentally Friendly Project with UNIDO

Petra completed a new project initiative in cooperation with UNIDO that aims to replace refrigerants that contribute to ozone depletion and have a high GWP. R290 that is known for its low GWP and zero ODP, was used as a refrigerant in the manufacture of large commercial rooftop HVAC units of up to 113 tons (400 kW).
