Process and packaging demand
Record the actual flow, pressure, quality and event pattern of each user. Short simultaneous requests can cause local problems that average compressor output conceals.

Food plant compressed air systems.
Assess demand before adding capacity.
Evaluate compressors, receivers, drying, distribution, quality and real equipment demand as one operating system.
How DPS can scope the process and investment decision.
Start with the business outcome
Pressure complaints do not automatically justify another compressor. DPS can coordinate source, storage, treatment, distribution, controls and equipment interfaces with qualified specialists. Compare metered operation and the actual user requirement. A leak or control correction can reduce purchased energy, but it does not establish extra accepted food output without a separate production case.
The responsible product / equipment teams specify air quality and any product-contact requirements. Qualified specialists establish receiver / pressure systems, electrical work and treatment packages. No generic air-quality class or universal leak saving is assigned to the plant.
Product and operating requirements: materials, quality and equipment duty.
Source / receiver / dryer train
Check controls, load states, storage, treatment and available duty together. A receiver cannot create source energy or cure an unsuitable air-quality basis.
Distribution and leakage
Measure local pressure loss and nonproductive demand. Repair priorities should follow measured loss and the ability to isolate / verify work, not only audible leakage.
Compare the process sequence, equipment options and interfaces.
Meter the system and map equipment requests across production and nonproduction states.

Investment boundaryThe preset is a hypothetical intervention in an existing operation. Defined capital scope, separate site additions, owner startup expense and working capital have different boundaries. Verify useful output, purchase reductions and payroll changes independently.
Compile equipment demand, concurrent events and required air quality before source / receiver / dryer selection. Include distribution, electrical, controls and annual service costs.

Worked operating case
Hypothetical screening case: 250 days × 0 equivalent useful hour/day × 0 accepted kg/h × 0% realization, capped at 0 kg incremental demand, gives 0 additional sold kg/year. Net price $0/kg less incremental variable cost $0/kg gives $0/kg contribution. Verified baseline purchase savings are $0, realized payroll savings $0, energy $40,000, cleaning resources $0 and maintenance $5,000 per year. Deduct $8,000 additional annual fixed cost. The default is energy-led and assumes no additional product sales. It does not convert a pressure improvement or leak estimate directly into production revenue.
Calculated from these assumptions: steady annual net benefit $37,000; year-one net cash $28,000; cash payback Beyond 5 years; five-year NPV at 10% is −$84,923. Change the assumptions below to test a different case.

All defaults are illustrative. The default case is an operating-plant improvement, not a greenfield quote. For a new operation, set baseline savings to zero and enter every additional operating and capital cost.

| Upside | $37,000 | −$84,923 | Beyond 5 years |
Downside: installed and site costs +20%, realization ×0.75 and unit contribution reduced by 20% of its absolute value. Upside: realization ×1.15, capped at 100%, and unit contribution improved by 10% of its absolute value. The demand ceiling still applies.
Formulas, scope and double-counting rules
Initial cash = (defined project scope + site additions) × (1 + contingency) + separate startup / shutdown cost + working capital. Contingency is conservatively treated as spent initially.
Sold incremental kg = min(days × recovered hours/day × constrained good kg/hour × realization, incremental demand). Contribution = sold incremental kg × (net price − incremental variable cost). New-volume labor, energy and packaging belong in that variable cost.
Baseline material benefit uses the verified percentage of actual purchases avoided at unchanged accepted baseline output. It is not a direct subtraction of two loss rates. Count a recovered kilogram once, either as its applicable cash saving or as incremental contribution.
Net annual benefit = contribution + independently realized baseline cash savings − added fixed operating cost. Year one scales gross benefits by the ramp factor while paying the full added fixed operating cost. Do not also count the same launch loss in the one-time startup amount.
Cash ROI = net annual benefit / initial cash. Five-year net ROI = (five-year cash inflows − initial cash) / initial cash. NPV = −initial cash + Σ cash flow(t)/(1 + discount rate)^t. Payback uses annual cash with linear interpolation within the recovery year. The threshold solver excludes terminal working-capital recovery.
This is a five-year screening horizon, not an asset’s entire life. No tax, debt, depreciation, grants, escalation, asset resale or additional replacement capital is modeled. Include recurring service costs in operating expense and use a detailed monthly budget for formal capital approval.

Food plant compressed air systems project FAQ
Can a bigger receiver solve every pressure drop?
No. Storage can address certain demand events, but source, distribution, treatment and user requirements must be assessed together.
What air quality does a food plant need?
Define the actual equipment and product-contact requirements with the responsible qualified teams. This page does not assign one universal specification to all users.
Can we use an industry leak percentage in ROI?
Use it only as a screening question, not as an achieved saving. Meter your system and cost the verified reduction at the actual tariff and service boundary.
Are these prices or returns a DPS commitment?
No. The example inputs exist to make the business-case calculation reviewable. Actual scope, prices, schedule, savings and performance need project-specific assessment and agreement.
What should the first DPS conversation include?
Bring the product and package mix, operating baseline, commercial target, retained assets, site constraints, available outage window and the capital options you are considering. Mark unknowns for measurement or supplier trials.
Bring an operating baseline and a testable investment brief.
Prepare the information below, export the assumptions you have modeled, and discuss the unknowns with DPS. An unmeasured input is a question to resolve, not a reason to invent precision.
