Deeply pigmented adhesives and thick bond layers both do the same thing to a UV cure schedule: they absorb dose before it reaches the depth that still needs to react, and the only real fix is more available energy per pass.
The Ceiling Configuration for UVA-Only Arc Curing
The Incure CDM™ + F200x2A pairs the CDM™ 9-inch polypropylene belt conveyor with two 600W F200 UVA lamp heads mounted in series, with no UVC tube. At 6 ft/min it delivers 4,500 mJ/cm² UVA — more than any other arc configuration on the CDM™ fleet at the same belt speed, including the F100x2AC (1,050), F100x2A (2,100), and F200x2AC (2,250). At the slowest setting, 1.5 ft/min, dose reaches 18,000 mJ/cm² UVA, giving formulations that need extended or high-energy exposure the widest dose headroom available on this platform.
Doubling the F200x2AC at Every Belt Speed
The F200x2AC delivers 2,250 mJ/cm² UVA at 6 ft/min from a single 600W lamp assembly. The F200x2A mounts two of the same 600W heads in series — each part passes under both in one belt run, accumulating exactly double the dose at every point across the speed range, from 18,000 mJ/cm² at 1.5 ft/min up to 2,260 mJ/cm² at 12 ft/min. In practice that means the F200x2A can run roughly twice the belt speed of the F200x2AC for an equivalent dose target, or hold the same speed with a full 2× safety margin built into every production run.
UVA-Only by Design
No UVC tube means no UVC ventilation or PPE overhead — this configuration is the right fit specifically when a process is qualified under UVA-only arc lamp exposure and the goal is maximum available UVA energy, not broadband coverage. If a formulation’s qualification data specifies UVA + UVC together, the F200x2AC single-assembly configuration is the correct alternative; broadband qualification data doesn’t transfer to this UVA-only configuration without re-validation.
Working out whether maximum UVA dose or broadband coverage is what a specific adhesive actually needs is worth confirming directly — Email Us with your formulation’s qualification data and Incure can help match the configuration.
Maintenance and Uniformity
Both lamp heads should be replaced on the same maintenance cycle — planned at the 1,000-hour threshold per head — to keep dose uniform across the two exposure zones rather than letting one head degrade ahead of the other. Dynamic uniformity at 2.0 inches is 0.82, consistent across the F-series arc lineup on this platform. As with every arc configuration on the CDM™, there’s no external PLC/RS-232 port; for process integration requiring external control signals, an LED configuration on the same chassis is the alternative — see the Incure L-Series™ UV LED Flood Lamps family for the LED heads available on this platform.
This is one configuration within the broader Incure CDM™ UV Conveyor lineup — matching maximum available dose to what a formulation actually requires avoids over- or under-specifying the lamp configuration.
The Same Chassis Handles the Whole Range
Because every F100/F200 arc configuration on the CDM™ shares the same 9-inch polypropylene belt and 8-inch part-width envelope, a line specified conservatively at the F100x2AC tier can step all the way up to the F200x2A’s dose ceiling later without touching the conveyor itself — only the lamp assembly changes. That continuity is worth factoring into an initial equipment decision: there’s less risk in starting at a lower tier and upgrading based on real production dose data than there might first appear, since the upgrade path doesn’t require replacing the underlying platform.
Belt and Curing Envelope
Like the rest of the F100/F200 arc lineup, the F200x2A runs on the CDM™’s 9-inch polypropylene belt (anti-static option available), with belt speed adjustable from 1.5 to 12.0 ft/min, curing height adjustable from 0.5 to 5.0 inches, and maximum part width of 8 inches — the two 600W heads increase dose, not usable belt footprint. Power input is 100–240V, 50/60Hz auto-ranging, with forced-air cooling and exhaust ventilation required for both heads.
Comparing Against the F400x2A
It’s worth noting the F200x2A isn’t the only dual-UVA option on the fleet — the F400x2A delivers even more total dose per pass (5,260 mJ/cm² at 6 ft/min versus the F200x2A’s 4,500) but at the cost of a narrower 5-inch maximum part width instead of the F200x2A’s 8 inches. For parts that fit within 5 inches, the F400x2A is worth comparing directly; for anything wider, the F200x2A remains the higher-dose UVA-only option available at the full 8-inch part width.
Is Maximum UVA-Only Dose Actually the Requirement?
It’s worth pausing before defaulting to the highest-dose UVA-only configuration on the fleet: if a formulation cures reliably on the F100x2A or F200x2AC at typical belt speeds, the F200x2A’s added dose is headroom, not a requirement — useful for future formulation changes or throughput increases, but not something every process needs from day one. The F200x2A earns its place specifically on lines running deeply pigmented, UV-absorbing, or unusually thick-bondline formulations where a lower-dose configuration has already been tried and found insufficient, or where belt speed targets genuinely require the extra dose margin to hit throughput without slowing down.
