How do you calculate good fill plant capacity?

Multiply cylinders per cycle by available cycles for gross capacity, then multiply by uptime and first-pass yield. With 24 cylinders × 18 cycles × 88% × 96%, you get 364.95 good cylinders from a 432-cylinder gross.

What's the difference between gross and good fill capacity?

Gross is the theoretical maximum — rack size times cycles, or 432 cylinders here. Good capacity is what actually passes uptime and final release, 364.95 cylinders, after losing 51.84 to downtime and 15.21 to yield failures.

What is a good first-pass release yield for cylinder filling?

For standard industrial gases, 96 to 99% first-pass release is typical; specialty and high-purity gases run lower because purity analysis rejects more cylinders. At 96%, you're losing about 15 cylinders per 432-cylinder run to release failures.

Is uptime or yield costing me more cylinders?

Compare the two loss lines directly. Here downtime costs 51.84 cylinders versus 15.21 from yield, so uptime is the dominant constraint — improving compressor and changeover availability would recover more output than chasing yield.

How do I increase fill plant capacity?

You can add cycles, enlarge the rack, lift uptime, or improve yield. Because losses compound multiplicatively, attacking the largest loss line first gives the biggest gain — here that's the 51.84-cylinder downtime loss.

Why multiply uptime and yield instead of adding them?

They're sequential losses: cylinders first have to be filled during available time, then those filled cylinders have to pass release. The survivors clear both gates, so the factors multiply — 88% × 96% leaves 84.5% of gross as good output.

Industrial Gases & Cryogenic Systems calculator

Fill plant capacity Calculator

A cylinder fill plant's nameplate throughput is almost never what it actually ships. Compressor downtime, pallet changeovers, and analytical holds eat into available cycles, and cylinders that fail purity or pressure checks at final release don't count as good output. This calculator turns rack-size and cycle count into a realistic good-cylinder figure by multiplying gross capacity through expected uptime and first-pass release yield, then breaking out exactly how many cylinders each loss costs you. Fill-plant managers and S&OP planners use it to commit to delivery volumes they can actually hit and to see whether uptime or yield is the bigger constraint on output.

What this calculator does

Estimate accepted fill plant capacity from cylinders per fill cycle, available cycles, plant uptime, and first-pass release yield.
Use it when checking whether a gas fill plant can cover cylinder demand, dewar fills, bundle fills, or specialty gas batch requirements.
It computes good (releasable) fill plant capacity in cylinders by adjusting gross rack throughput for uptime and first-pass release yield.

Formula used

Gross fill plant capacity = cylinders or containers per fill cycle × available fill cycles
Good fill plant capacity = gross fill plant capacity × expected fill plant uptime × first-pass release yield

Inputs explained

Cylinders or containers per fill cycle:
Available fill cycles:
Expected fill plant uptime:
First-pass release yield:

How to use the result

Use it for shift or weekly capacity planning, order-promising, and diagnosing whether downtime or release failures is your tighter constraint.
It assumes a fixed cylinders-per-cycle rack size; mixed cylinder sizes, gas changeovers, and purge-down losses between products aren't modeled and would reduce real output further.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
