UV Curing calculator
UV Oven vs UV Cure Payback Calculator
Replacing a gas or electric cure oven with UV cure unlocks energy savings, frees significant floor space, and usually slashes cycle time from minutes to seconds — but the capex is real. This calculator combines installed UV cell cost against the annual savings (energy delta + floor-space rent freed + cycle-time labor freed) and any new UV maintenance to give a years-to-payback number you can defend in a capital request.
What this calculator does
- Compare a UV cure cell's installed cost against the energy + floor-space + cycle-time savings vs a thermal cure oven on the same product.
- Use it on capital reviews when the question is whether to displace a thermal cure oven (gas or electric) with a UV cure cell on a new or refreshed line.
- Returns years to payback for a UV cure cell displacing a thermal cure oven, plus net annual savings.
Formula used
- Net annual savings = annual thermal savings − annual UV operating cost
- Payback (yr) = installed cost ÷ net annual savings
Inputs explained
- UV cell installed cost: All-in: UV head, fixturing or conveyor, controls, install labor, validation, ventilation changes.
- Annual savings vs thermal oven: Energy delta + floor-space rent freed + labor freed by faster cycle + scrap reduction.
- Annual UV operating cost: Lamp / array consumables, validation cadence, any new utilities (chiller, exhaust).
How to use the result
- Use it on capital review for line refreshes, new program launches that would otherwise require an oven, and any time floor space is the binding constraint at the plant.
- Payback model only — it doesn't capture chemistry-change cost (most thermal-cure resins need re-formulation as UV-cure), substrate-temperature compatibility (UV is much cooler — lets you cure on heat-sensitive substrates the oven couldn't handle), or product-quality wins (faster cycle = less ambient contamination).
Common questions
- What's a typical payback for thermal-to-UV? 1–3 years on energy-heavy ovens (gas-fired bake ovens running 24/7 are the sweet spot). 3–5 years on electric ovens with moderate utilization. Past 5 years, the case usually rests on floor space (UV cells are ~10–20% the footprint of an oven of the same throughput) or cycle time, not energy.
- How do I value floor space? At fully-loaded $/ft²/yr — that's rent + utilities + insurance + the opportunity value of using that space for capacity. In coastal U.S. plants this often runs $25–$60/ft²/yr; freed space from displacing an oven (200–800 ft²) makes a real number on the savings line.
- What about chemistry change cost? Real and not in this calc. Most thermal-cure formulations need re-formulation as UV-cure (different resins, photoinitiators, additives). Add 6–12 months of formulation work and any qualification cost as a one-time uplift to the UV cell installed cost — that often pushes payback from 18 months to 30.
- Does this model substrate-compatibility wins? No, but they can be the deciding factor. UV cure happens at near-ambient surface temperature, so heat-sensitive substrates (thin films, heat-strain plastics, electronics) become accessible. If the new product mix needs that, value it as enabled-revenue rather than savings.
