Air Separation Units (ASU) and Cold Boxes
PTC supplies small, medium and large industrial gas plants using cryogenic technologies for high-purity oxygen, nitrogen and argon production.
Petro Kara Energy Hiva (PTC) is active in the design, manufacture and supply of air separation units (ASUs) and can provide industrial-gas plants in small, medium and large capacities with maximum local-manufacturing participation.
Through capable engineering and R&D teams and cooperation with established international licensors, PTC offers high-performance, energy-efficient ASU plants. Artificial intelligence and new-generation intelligent controls improve operation, reduce energy consumption by up to 15 percent and shorten plant delivery time.
