Why Piped Medical Gas System Piped Medical Gases System is a concept, in which different gases are conveyed constantly at the specific pressure and flow through copper pipeline in different areas of hospital from source units. Oxygen, nitrous oxide & carbon di-oxide is achieved by keeping sufficient quantity of gases and liquid in bulk high-pressure in a cylinder or liquid storage tank. Air compressor and vacuum pump achieve medical air and central vacuum. The out coming gases from source units are regulated by automatic control panels and finally reaches to the outlet point for patient use. All the components & designing of PMG system compiles with all these relevant standard of BS, HTM-2022 (U.K.), NFPA (U.S.A.), CSA (CANADA), DIN (FRANCE). PMG system is efficient, economical, hygienic, convenient and flexible to customers need.
