Push an air-cooled LED array hard enough for long enough and intensity starts drifting downward mid-shift as heat builds faster than the fans can pull it out — a problem that shows up as inconsistent cure quality between the first part of a production run and the two-hundredth. Incure’s W-Series™ removes that ceiling with closed-loop water cooling, trading a plumbing connection for headroom an air-cooled array can’t reach.
Two Models, Same Water-Cooling Principle
W44 covers a 4″×4″ curing area with 144 high-power LEDs; W1212 scales up to a 12″×12″ area with 1,296 LEDs. Both use the same closed-loop water-cooling architecture, sized to the LED count each model carries. W44 suits compact, bench-top setups where a smaller footprint fits the fixture; W1212 targets large-area or inline production curing where covering more surface per cycle matters more than peak intensity at any single point. Recommended working distance on both models is 1 to 3 inches, with peak intensity specified at 2 inches; static uniformity across the field runs 0.78 at 2 inches and 0.62 at 3 inches, improving to 0.88 and 0.82 dynamic uniformity when the part or lamp is in motion during cure, relevant on any inline-integrated installation.
Water Cooling Buys Higher Intensity, Not Just Longer Duty Cycles
The intensity gap between the W-Series™ and Incure’s air-cooled L-Series™ flood lamps is the real reason to specify water cooling, not a side benefit. W44 delivers 8,100 mW/cm² at 365 nm — more than double the 3,100 mW/cm² the similarly-sized, air-cooled L44 produces at the same curing area. The same gap holds at the larger end: W1212 reaches 3,100 mW/cm² against L1212’s 1,900 mW/cm² over the identical 12″×12″ field. Packing that many LEDs into the same footprint generates more heat than forced air can remove fast enough to sustain the higher output, which is exactly the ceiling water cooling exists to raise.
One Wavelength Per Unit
Each W-Series™ model ships in 365, 385, 395, or 405 nm, factory-configured to a single wavelength at the time of order — the same configuration rule as Incure’s L9000™, L-Series™, and M-Series™ lines. As on those lines, intensity reads higher at 365 nm than at the longer wavelengths on both W44 and W1212, so confirming the adhesive’s absorption peak has to happen before the order is placed rather than adjusted once the unit is installed.
Chamber Compatibility Mirrors the L-Series™ Split
W44 pairs with Incure’s C131C and C131D cure chambers; W1212 pairs with the larger C191C — the identical chamber assignments as the L44 and L1212 air-cooled models covering the same curing areas, detailed in Incure’s guide to B/C-Series™ cure chambers. A facility already running enclosed batch curing on an L-Series™ lamp can move to the water-cooled equivalent for the intensity increase without changing chamber hardware.

Water Cooling Requires Plumbing, Not Just Power
Unlike the air-cooled L-Series™ or M-Series™ lines, W-Series™ installation needs water inlet and outlet connections in addition to the standard 100–240V auto-ranging power input — a facility infrastructure requirement that has to be planned into the installation, not just the electrical drop. That’s the real trade-off behind the intensity gain: water cooling isn’t a drop-in upgrade to an existing air-cooled fixture location unless coolant lines are already available or can be run to it.
Where the W-Series™ Fits
High-volume electronics assembly — continuous-cycle PCB conformal coating cure, underfill sealing, and SMD component bonding — is the clearest fit, where sustaining full rated intensity across an entire shift matters more than on a low-duty-cycle bench station; the same coating-cure logic applies whether the lamp is air- or water-cooled, covered from the air-cooled side in Incure’s guide to UV LED flood lamps in conformal coating lines. Optical component work — lens bonding, prism assembly, and filter lamination — benefits from water cooling specifically because thermal drift in the lamp housing can shift alignment tolerances on precision optics, a risk sustained high-intensity air-cooled operation doesn’t fully eliminate. Inline conveyor integration draws on the same PLC and RS232 signal inputs Incure’s CDM™ UV conveyor uses, so a water-cooled area lamp synchronizes into the same control architecture as the rest of the line. Batch and inline curing of UV conformal coatings, dome coatings, and encapsulants uses the large-area W1212 to cover multiple components per cycle at full rated intensity rather than indexing parts through a smaller field. In R&D settings, the timer and continuous operating modes support high-intensity adhesive qualification and cure-schedule development where consistent output at maximum intensity is part of the test itself.
