Medical Gas Outlet & Cost Calculator

It estimates the distribution side only: terminal units, copper pipework, valves and AVSUs, alarm coverage, bed head panel or pendant interface, installation labour and brazing, and testing and certification. It excludes the source plant entirely — PSA oxygen generation, liquid oxygen tank and vaporiser, manifold banks, medical air and surgical air plant, and vacuum plant are all priced separately because plant selection depends on total flow demand rather than outlet count.

It depends entirely on the clinical area, which is why the calculator asks you to split beds by type rather than accept a single bed count. A general ward bed typically needs two outlets, oxygen and vacuum. An HDU or step-down bed usually needs three. A Level-3 ICU bed generally needs five or six, covering oxygen, medical air, vacuum and often a second oxygen point. A major theatre needs a full thirteen-terminal suite including anaesthetic gas scavenging. Applying a ward ratio across a whole hospital is the most common sizing error we see in early budgets.

Because the decision is driven by consumption and resilience rather than by how many outlets you have. A hospital chooses between manifold banks, a liquid oxygen tank with vaporiser, or on-site PSA generation based on total oxygen demand, footprint, capital versus operating cost preference, and the redundancy the facility needs. The crossover points between those options — and the capex against opex comparison — are worked through in our medical gas cost guide, which is the right next read once you have an outlet count.

Pipeline run length and building geometry matter more than most budgets assume — a dispersed campus or a high-rise with long vertical risers costs materially more per outlet than a compact block. Retrofit into an occupied building adds labour cost through restricted working hours and out-of-hours tie-ins. Terminal unit origin is a significant swing, with imported BS, NIST or DISS units running roughly 1.8 to 3 times Indian equivalents. Copper price movement affects the largest single line item, since tube and fittings are typically 35 to 45 percent of the per-bed cost.

Yes, and it should be visible as a line in any quotation rather than buried. Purging, pressure testing, cross-connection testing and purity verification are what make the system safe and what a NABH assessment expects documentation for. It typically runs 5 to 8 percent of the installed cost. A quotation that omits it is not cheaper — it has simply moved a mandatory cost off the page, and you will pay it later, usually under time pressure before commissioning.
