When a conveyor process is already running at target throughput but isn’t quite reaching full cure, the instinct is to slow the belt down — the CDM™ + F100x2A exists so that isn’t the only option.
Two Heads, Double the Dose, Same Speed
The Incure CDM™ + F100x2A pairs the CDM™ 9-inch polypropylene belt conveyor with two 400W F100 UVA lamp heads mounted in series along the belt. Each part passes under both heads in a single pass, accumulating dose from each consecutively — the result is 2,100 mJ/cm² UVA at 6 ft/min, exactly double what the single-assembly F100x2AC delivers at the same belt speed. That doubled dose holds across the full speed range: at 12 ft/min the F100x2A still delivers 1,060 mJ/cm² UVA, matching what the F100x2AC achieves at half that speed.
UVA-Only, No UVC Compliance Layer
The F100x2A configuration uses two UVA lamp heads only — there’s no UVC tube. Facilities that haven’t installed UVC-rated exhaust ventilation, or that run under a process qualification specified as UVA-only arc lamp exposure, get the full doubled-dose benefit without introducing a UVC handling requirement. If an adhesive’s SDS or qualification data specifies mercury-arc exposure that includes UVC, the F100x2AC single-assembly configuration is the correct choice instead — the two configurations aren’t interchangeable once UVC is part of the qualification.
Where the Extra Dose Actually Helps
Doubled UVA dose isn’t just a safety margin on paper — it directly supports deeper bondline cure, UV-absorbing or pigmented formulations that need more energy to reach full conversion through the material depth, or a belt speed increase for the same dose target a single head can only hit at half the throughput. For a line running at process minimum with a single F100 head and looking for either more margin or more speed, the F100x2A is the direct next step on the same conveyor platform.
Working out whether a UVA-only or broadband configuration fits your adhesive’s actual qualification data is worth confirming before ordering — Email Us with your process specification and Incure can help match the right configuration.
No External Control, and What That Means
Like the rest of the F-series arc configurations on the CDM™, the F100x2A has no external PLC or RS-232 control port — belt speed adjustment is the only process control available. For process integration that requires external control signals, an LED configuration on the same conveyor chassis is the alternative path — see the Incure L-Series™ UV LED Flood Lamps family that includes the CDM™-compatible L64 and L88 heads. Bulb replacement is planned at the 1,000-hour threshold per head, and both heads should be replaced on the same maintenance cycle to keep dose uniform across the two exposure zones.
This configuration is one of several Incure lamp-head options on the Incure CDM™ UV Conveyor platform — matching lamp configuration to both your adhesive’s dose requirement and your line’s control needs takes a look at the whole process.
A Straightforward Upgrade Path
Because the F100x2A shares its conveyor chassis and belt platform with the entry F100x2AC configuration, moving from one to the other is a lamp-head addition rather than a full system replacement — a line that starts with the single-assembly F100x2AC and later finds it needs more UVA dose can add the second head without re-plumbing the conveyor or reconfiguring the belt. That makes the F100x2AC a reasonable starting point for a new process with uncertain dose requirements, with the F100x2A as a known, straightforward upgrade if production data later shows it’s needed.
Belt and Curing Envelope
The F100x2A runs on the CDM™’s standard 9-inch polypropylene belt (anti-static option available), with belt speed adjustable from 1.5 to 12.0 ft/min and curing height adjustable from 0.5 to 5.0 inches — a wide enough range to accommodate parts from thin flat panels to taller fixtured assemblies without a chassis change. Maximum part width is 8 inches, matching the F100x2AC single-assembly configuration exactly; adding the second lamp head increases dose, not the usable belt footprint.
When Two Heads Beats a Faster Belt
A common instinct when a process is under-curing is to slow the belt down — but that trades throughput directly for dose, one-for-one. Adding a second lamp head instead increases available dose at the same belt speed, which is the more throughput-efficient fix whenever the underlying limitation is total UV energy rather than something belt-speed-independent like fixture dwell time or a curing chamber’s physical length. Confirming which constraint actually applies to a specific line before choosing between “slow the belt” and “add a head” avoids solving the wrong problem.
Uniformity Across Both Heads
Dynamic uniformity at 2.0 inches working distance is 0.82, with static uniformity at 0.75 — typical values for the F-series arc lineup with roughly ±5% measurement variation. Because both heads contribute to the combined dose figure, keeping both lamp heads on the same replacement cycle isn’t just a convenience — a mismatched pair with one head well past its 1,000-hour mark and one freshly replaced introduces a real uniformity gap between the two exposure zones that a single combined-dose reading won’t necessarily catch.
